Who Pays for the Wider Grid? Cost Allocation across Transmission Regions

1 The allocation decision before capital is committed

A wider-grid investment needs a defensible answer to two separate questions. The first concerns the distribution of the project's resource cost across the regions receiving its services. The second concerns the instruments through which the asset owner can actually collect those contributions. This paper proposes a linked decision record for both questions. The analysis begins with a specified facility and a dated comparison with the system that would exist without it. It then tests the distribution of estimated benefits, the stability of possible contributions, and the timing of the receipts supporting financing. Each test has its own accounting boundary.

The proposed contribution is a reproducible sequence of decisions, supported by an illustrative three-region calculation. Its allocation account places the shared resource cost and regional benefits on one appraisal date and one discount convention. Its cooperation account asks whether individual regions or coalitions would pay more than the assumed cost of their alternative. Its financing account follows the owner invoices and debt payments. The numerical case establishes consequences within explicitly stipulated inputs. It supplies no actual tariff, engineering certification, negotiated agreement, market valuation or financing commitment. A real transaction would need evidence for each of those matters before the same calculation could inform an investment approval.

For an investment committee, the initial output should identify the amount of capital whose repayment depends on an unresolved allocation decision. A useful submission names the candidate payers, the proposed contribution instrument, the approval still required and the maximum expenditure permitted before that approval. A project sponsor could use a conditional procurement commitment while resolving the payer question, provided the cancellation liability and cash covering it were separately verified. The appropriate expenditure limit depends on those documents. System value alone cannot establish the amount that a lender could advance against a future receivable.

The facility definition should cover the connection points, enabling works and asset ownership. A common cost pool can unintentionally include an individual customer's connection equipment or exclude a shared substation. Either error affects the denominator used in every allocation. The decision record therefore needs an explicit reconciliation from the engineering scope to the cost estimate, from the estimate to eligible expenditure and from eligible expenditure to the proposed payer obligations. A public subsidy should appear as a separately identified funding source. Treating an announced subsidy as a confirmed collection would require additional evidence of eligibility, award, conditions and timing.

The framework is intended for an advisor, asset owner, regional planning body or capital provider reviewing a specific cross-regional commitment. It does not select a universal allocation formula. The substantive question is whether a proposed formula remains defensible under the governing method, the chosen counterfactual, plausible changes in system use and the collection instruments available. The following jurisdictional review is deliberately bounded to the identified primary materials. It makes no assertion that every current compliance filing, appeal, licence condition or bilateral project agreement has been examined. The project file should resolve those limitations through the relevant legal and regulatory review.

Author-proposed diligence structure; no executed contract, legal obligation or approved recovery route is represented.

2 Define the transmission boundary before naming the payer

The proposed comparison begins with the asset and the planning boundary across which its costs would move. Identify the line, terminal equipment, associated reinforcements and interfaces required for the service. Record the regions containing each element, the users receiving the proposed service and the authorities that can approve its recovery. These boundaries need separate documentary support. A benefit reaching another region can justify examining a contribution; the calculation alone supplies no enforceable claim against that region's customers.

FERC's Order 1000 requires neighbouring planning regions to develop common interregional allocation methods, with flexibility between regional pairs. Eligibility involves selection in the relevant regional plans. Its principles link allocated costs to estimated benefits and restrict involuntary charges outside the regions containing the facility. A voluntary third-region agreement can have a different perimeter. These are framework requirements, with implementation dependent on the applicable tariffs. [1]

FERC's official explainer describes Orders 1920, 1920-A and 1920-B as long-term regional planning and allocation reforms, including a minimum twenty-year horizon. It expressly cautions against legal reliance on the explanation. This regional framework should be read alongside the separate interregional arrangements; this paper establishes no nationwide cross-region formula or project-specific charging right. [2]

For the proposed alternatives analysis, put each candidate on one service specification. A regional reinforcement, a cross-region corridor and a smaller local solution should address the same stated need before their costs are compared. Record residual constraints and dependencies explicitly. If one alternative needs an additional substation, include its cost and readiness condition. A comparison that leaves a necessary interface outside one candidate gives that candidate an unsupported advantage.

The decision record should identify which allocation question is unresolved. It could concern eligible expenditure, beneficiary identification, the selected method or its implementation through charges. Assign a separate review action to each issue. This permits expenditure on an evidenced package while leaving a wider contribution conditional. The method proposed here supplies no selection approval, tariff disposition, court-outcome finding or authority to charge an unwilling neighbouring region.

3 Connect US benefit evidence to the applicable allocation decision

Order 1920-A preserves cost causation and allocation roughly commensurate with estimated benefits. Paragraphs 778-780 permit multiple methods, known before selection, and different benefit weights or additional benefits within that discipline. They do not prescribe one proportional-benefit calculation for every long-term regional facility. [3]

Order 1920-B explains that FERC considers the entire record when choosing a replacement rate. State-agreed approaches receive consideration, with no generic preference over transmission-provider proposals. Its case-specific decision process supplies no payment undertaking by a state participating in allocation negotiations. [4]

FERC's current compliance schedule separates filings covering the other Order 1920 requirements from filings covering interregional coordination. Listed extensions vary by region and include dates in 2027. This procedural table verifies no completed filing, approved tariff or selected project's recovery outcome; this review also makes no appeal-disposition finding. [5]

The proposed benefit register should preserve the difference between a measurement and a charging proposal. Give each benefit an event, location, affected party, calculation method and reference case. Reliability support should identify the constraint addressed; production-cost savings should identify the dispatch comparison; an avoided reinforcement should identify the expenditure displaced. Record the uncertainty that changes the beneficiary ranking. These are proposed review controls, with no estimated project benefit supplied by this paper.

Then prepare an allocation bridge. Start with the expenditure being considered for recovery, identify the applicable method and show the resulting proposed obligations. A negotiated contribution should retain its conditions and relationship to the remaining charge. Changing a benefit weight in a sensitivity must not silently change an approved payment obligation. Present the analytical alternative and the governing allocation case separately, with the additional approval needed to move between them.

Finally, name the instrument required before construction relies on the proposed contribution. Legal review should establish its effective terms and applicable challenge process. The financing case needs the invoice issuer, recipient, payment condition and collection date. State participation, a favourable beneficiary calculation and an anticipated compliance decision should retain their separate status until those documents support usable receipts.

4 Apply the European investment request within its eligible scope

Article 16 of TEN-E addresses eligible project categories and specified exemptions. It allocates efficiently incurred investment costs, excluding maintenance, with network-tariff recovery to the extent other charges or congestion rents do not cover them. Investment requests include project-specific cost-benefit analysis and a financial business plan. National regulators decide jointly; failure to agree within six months, or a joint referral, invokes ACER's decision route. The April 2026 consolidated text is a documentation tool. [6]

The proposed European diligence should therefore begin with eligibility and the precise request. Identify the project-list entry, category, promoter, relevant regulators and any exemption affecting the route. Obtain the investment request and the resulting decision before treating a cross-border amount as an approved allocation. A project's international location alone does not establish eligibility under this procedure. The comparative method supplies no finding that a particular project or expense qualifies.

Next, construct two reconciled schedules. The economic schedule records the proposed project's incremental benefits and costs by country. The financial schedule records construction funding, eligible recovery, financing costs and collected receipts by legal entity. A country-level net benefit is an appraisal output; the receipt used to pay a contractor needs a separate payment route. Show the chosen tariff implementation and every outstanding decision affecting the interval between expenditure and collection.

The request should be tested against a defined change case. A reduced design, delayed commissioning or additional reinforcement can alter both national impacts and the requested investment amount. Recalculate the economic comparison, then identify which financial terms would need reconsideration. An assumed transfer cannot automatically expand because the construction estimate rises. The proposed review should ask whether the decision contains an adjustment mechanism, what evidence activates it and whose funds bear the unresolved amount.

The resulting recommendation is a bounded commitment against the reviewed allocation and payment documents. It should identify expenditure ready for authorisation, recovery still conditional and the party funding any dated difference. No tariff-payment timing, financing commitment or project-specific implementation decision is verified in this paper. Authentic legislative texts and the relevant national decisions remain necessary for legal reliance.

5 Test European counterfactuals and overlapping compensation

ACER's June 2023 recommendation asks for reference-network and counterfactual information, country-level results and sensitivity analysis. It cautions against double-counting national impacts and double remuneration through other support. Its guidance addresses investment requests and tariff inclusion; the actual national implementation remains with the relevant regulators. [7]

ACER's May 2026 policy paper distinguishes congestion-income distribution, compensation for hosting cross-border flows through ITC, and CBCA for prospective infrastructure. It evaluates reform options and their interaction. These options are policy analysis; they supply no enacted common financing mechanism or additional project entitlement. [8]

The proposed alternatives review should retain the network that exists without the candidate. List projects included in that reference, their readiness assumptions and their relationship to the candidate's service. When two candidates perform overlapping duties, test each against a consistent baseline. A benefit attributed to one candidate should not depend silently on excluding a competing asset while its competitor's assessment assumes that asset is already available. Any difference needs an explicit technical explanation.

For complementary investments, prepare a joint comparison and a contribution analysis for each component. Identify which benefits require the complete package and which survive if one component is delayed. This proposed control makes the dependency visible before costs are allocated to individual promoters. A component's incremental benefit under the full package can differ from the benefit of installing it alone; the approval should state which question the presented calculation answers.

The recovery bridge should also identify receipts that offset the same cost. Record contributions, awarded support and other evidenced recovery against the eligible expenditure categories. Keep an expected award conditional until its terms are established. A policy discussion of future cost sharing should have no automatic effect on present cash sources. The final comparison should show the unrecovered balance and the authority needed to alter it. This paper supplies neither an empirical welfare estimate nor a forecast of the outcome of European reform proposals.

6 Separate Great Britain network charges from interconnector adjustments

NESO's current generator guidance describes TNUoS as recovery of transmission-owner expenditure, collected from generators and suppliers and paid to owners. Liability depends on connection arrangements; charging includes wider and local elements. The publication listing dates this guidance to September 2026. Its explanation establishes no charge for the hypothetical asset or international allocation proportion used in this paper. [9]

Ofgem's December 2024 handbook explains conditional interconnector floor payments and transfers above the cap through the TNUoS process. It covers specified point-to-point regime windows, excludes offshore hybrid assets from that handbook's scope, and gives licence conditions precedence over its general guidance. A floor adjustment is therefore subject to the applicable regime and licence. [10]

The proposed comparison should identify the domestic reinforcement and the interconnector separately. Record the owner of each asset, the expenditure included in each assessment and the instrument supporting recovery. Then show how one asset's readiness depends on the other. A consumer benefit attributed to an interconnector should identify the supporting domestic network assumed in the analysis. Its cost should remain visible where the service requires that reinforcement.

The cash schedule should distinguish market receipts, conditional regulatory adjustments and the domestic charging cycle. Identify the event that determines an adjustment and the date funds become usable. An appraisal of consumer welfare should remain outside the developer's revenue unless a reviewed instrument creates the corresponding payment. Likewise, the participation of consumers in a charging process should not be treated as an unconditional payment promise for every proposed cross-border asset.

For a proposed downside, change the service date, market receipts and assessed costs separately. Obtain project-specific evidence before altering the adjustment formula or assuming an exception to its conditions. Report which party funds the intervening cash requirement. The comparative framework establishes no present cap or floor level, approved interconnector, actual domestic tariff, borrowing term or permission to extend this regime to another asset class.

7 Read Gulf governance and financing at their disclosed level

GCCIA's governance page assigns interconnection-expansion approval and tariff or fee decisions under the Power Exchange and Trade Agreement to the Electricity and Water Cooperation Committee. It describes an institutional decision route. The published page does not disclose a complete project allocation instrument, a member payment schedule or an unconditional regional guarantee. [11]

ADFD's June 2025 announcement reports a signed AED 752 million financing agreement for GCCIA's UAE expansion and describes the associated line and substation scope. It discloses no complete member-state cost allocation, loan draw conditions, repayment schedule or completed service outcome. The reported financing amount remains separate from projected economic benefits. [12]

The proposed transaction comparison should map the asset, borrower, beneficiaries and proposed payers independently. A regional institution can finance works in one country while the intended service has a broader perimeter. The allocation review needs the governing decision and agreements for those works. Record which contribution pays for construction, which charge pays for continuing service and which amount remains a forecast benefit without a corresponding owner receipt.

Interface costs deserve a separate allocation question. Identify the line, substations, protection changes and operating arrangements needed to make the service usable. For each item, establish ownership, acceptance responsibility and the consequence of delay. An illustrative arrangement could assign construction costs territorially while recovering shared service costs differently. That arrangement is a proposed case for analysis; its application would require the actual instruments and a dated sources-and-uses reconciliation.

A financing announcement should enter the evidence register at its reported stage. Request the disbursement conditions, permitted use, repayment source and support terms before using it in a cash-coverage model. Test a contribution becoming available after the first construction obligation and identify the funds bridging that interval. This review supplies no Gulf-wide tariff formula, sovereign support assumption, observed lending threshold or privately verified repayment obligation. Its recommendation is to authorise only the exposure supported by the reviewed agreements and available funding.

8 Distinguish Indian asset revenue from interstate charge sharing

CERC's original 2020 sharing regulations separate national, regional, transformer and AC-system components. The 2023 first amendment moves relevant sharing quantities to GNA and directs bills to drawee customers, leaving contractual settlement to the applicable power-purchase agreement or mutual agreement. These provisions identify distinct regulatory and contractual steps. A current calculation must use the amended framework and the customer's actual access position. [13]

CERC's 2024 tariff regulations cover specified section 62 determinations read with section 79 and exclude tariffs discovered through competitive bidding and adopted under section 63. This asset-tariff boundary differs from the question of sharing interstate charges among users. The paper verifies no individual tariff order or transmission-service agreement. [15]

The proposed review should build the bridge from the asset's authorised yearly charge to the customer's liability. Identify the tariff instrument, admitted elements, commercial-operation status and the applicable sharing calculation. Then obtain the account and billing documents that turn the allocated amount into a collection obligation. Reconcile revisions separately. An estimate of the asset's construction cost should not substitute for its admitted charge; a generic access quantity should not substitute for the customer's documented position.

The alternatives analysis should preserve those boundaries when comparing reinforcement designs. A smaller asset can change capital expenditure, technical service and the resulting recovery base differently. The proposed model should identify each link and show the documentary assumption supporting it. Changing the engineering cost without revising the assumed authorised charge would require an explicit explanation. Changing the user group can alter the sharing question without changing the owner's approved tariff in the same way.

Before lending against an allocation, identify the billed party and any contractual reimbursement expected from another participant. Treat those as distinct obligations, with separate conditions and collection dates. The proposed cash model should show a shortfall if reimbursement is late even when the regulatory bill remains due. No normative financing ratio, actual customer invoice, universal benefit-proportional formula or automatic recovery of increased construction cost is established by this comparative discussion.

9 Keep Indian waivers and the residual payer visible in the comparison

CERC's 2025 fourth sharing amendment changes allocation provisions and technology-specific waiver schedules. Eligibility depends on the specified category, relevant dates and conditions; the text also addresses terminal-bay charges when connectivity-related commissioning is incomplete. The notified rules, corrected Gazette text and subsequent administrative materials must be read within their scope. This review grants no particular project a waiver or extension. [14]

The proposed comparison should show the gross charge, the evidenced waiver and the remaining amount separately. Identify the party legally billed and any different party expected to bear the economic burden under contract. When a waiver assumption changes, update the relevant billing case and explain which other funding requirement changes. A lower charge to one participant alone leaves the wider system's expenditure and residual recovery question unresolved; the analysis needs the applicable allocation documents before assigning that balance elsewhere.

Waiver timing should also be retained in the alternatives. A project's stipulated commissioning or procurement date can place it in a different eligibility case. Show the evidenced date, the rule relied upon and any unresolved determination. An expected extension should remain conditional until its applicable decision is obtained. Compare the funded exposure if that extension is unavailable. This is a proposed diligence sensitivity, with no assertion about any actual project's delay cause or eligibility.

Across the jurisdictions, the proposed decision should retain a benefits account, an allocation account and a collected-cash account. The first supports selection among alternatives. The second records the governing distribution of eligible costs. The third identifies usable receipts and financing obligations on their dates. Reconcile each transfer between accounts and identify the document authorising it. The comparison should conclude with an exposure limit, a specific unresolved decision and a documented payer obligation. Public frameworks and announcements support bounded stages of that review; legal reliance and construction funding require the relevant project instruments.

10 Building a comparable benefit and payment record

The case uses three fictional regions to make the allocation problem visible without attributing the inputs to actual utilities or customers. Its region labels describe only the numerical example. Benefits are assumptions about avoided resource expenditure or service value. A contribution is a proposed share of shared cost. An owner receipt is a dated payment under a stipulated recovery instrument. Debt service is a separate financing outflow. The paper retains those definitions when moving between allocation tables and cash schedules. Combining benefit value with owner receipts would count an economic effect and its funding transfer as though they were independent value creation.

A comparable benefit register should begin with a physical effect and its counterfactual. For example, a reduction in modelled generation cost needs the same demand, fuel assumptions, topology and dispatch constraints in the two runs. An avoided local reinforcement needs an identified alternative asset, expenditure date and adjustment for any difference in delivered service. Reliability value requires a specified service measure and valuation convention. An unmonetised effect can remain in physical units until there is a defensible valuation. A qualitative approval criterion should have an explicit decision role; assigning an arbitrary cash value to it would create precision unsupported by evidence.

Overlap is a particularly important issue for a shared line. A dispatch calculation might already include the generation savings that are later presented as renewable-access benefits. Avoided reinforcement and capacity value might refer to the same underlying constraint. The proposed review assigns each monetised effect to one category and records its treatment in the other categories. Where partial overlap remains, the analyst should publish the adjustment and the resulting range. The fictional model uses disjoint categories by construction. That simplifying assumption does not establish that the categories in an actual grid study would be independent.

Beneficiary geography should be determined using the selected model's evidence rather than the location of towers. A region hosting a corridor can bear construction disruption and receive only part of its economic service. A distant region can receive an assessed benefit without owning a physical segment. The proposed file records both effects. Local land compensation, mitigation expenditure and a contribution toward shared system cost have different purposes and should retain separate treatment. A payment negotiated for corridor consent should not silently become an additional assessed system benefit or reduce a regional charge without a documented rule.

The financing review also needs a reconciliation between the eligible cost base and the capital provided. In the example, the owner capital charge uses a stipulated annuity convention that differs from the resource appraisal discount rate. The debt schedule uses its own stated rate and maturity. These are author-created assumptions. Their differences allow the reader to trace the effect of financing terms without treating the regulatory or contractual rate as a verified market observation. No claimed economic benefit is placed directly into the owner cash account. An actual investment would require executed or approved instruments establishing the payment amount and its collection conditions.

The evidence register should retain model versions, the date on which the allocation became fixed, and the conditions under which it may change. A revised demand forecast might alter an estimate of future benefit while leaving a previously agreed contribution unchanged. A material scope change might require a new approval. The decision record should identify the applicable rule before analysts recompute charges. Otherwise a technically updated study could be mistaken for authority to rewrite an existing obligation. The next sections use explicit assumptions to expose this distinction and make the calculations independently reproducible.

11 Define the beneficiary account before assigning a contribution

This original worked example concerns a fictional wider-grid asset serving three normalized regions, A, B and C. All quantities, scenario weights, contribution limits, alternative service costs and financing terms are author-created assumptions. The example establishes no actual allocation order, tariff entitlement, customer commitment or engineering outcome. Amounts are USD millions. The system appraisal uses a common time-zero date and a fifteen-year service horizon, with benefits and resource costs discounted at 6%. Construction costs 150 at time zero. Annual operating expenditure of 3.089 has a present value of 30, giving total resource-cost PV of 180. There is no salvage value or closure payment. The owner financing account begins at the same date, with its first debt payment at the end of year 1.

Benefit attribution separates energy savings, reliability losses avoided and flexibility value. For this arithmetic, energy savings exclude the outage losses counted under reliability; flexibility excludes both energy savings and outage effects already entered elsewhere. These definitions are stipulated boundaries, without a dispatch or reliability study validating their amounts. A real appraisal would require the underlying events, users and counterfactual to support that separation. The model enters each benefit once, attributes it to one region and records all three categories on the same valuation date. A benefit transfer between regions would change the regional entries without creating an additional system benefit.

The central scenario assigns total benefit PVs of 110, 80 and 50 to A, B and C. Its underlying category amounts are 65, 25 and 20 for A; 40, 25 and 15 for B; and 20, 15 and 15 for C. An A-led scenario changes those regional totals to 150, 60 and 30. A C-led scenario changes them to 70, 100 and 70. Each scenario totals 240, so the example deliberately isolates the allocation consequences of a redistribution in benefits. It contains no variation in aggregate benefit or construction cost across those three scenarios. The separate cost-escalation sensitivity changes the latter explicitly.

Illustrative weights of one-half, one-quarter and one-quarter produce weighted regional benefits of 110, 80 and 50. The word expected therefore means a weighted calculation conditional on those declared weights. No empirical likelihood is established. Total weighted benefit less resource cost is 60. That aggregate surplus provides room for more than one allocation; it does not identify a unique payer. Before using the example in a transaction, a decision team would need to replace the scenarios, category estimates and weights with its accepted evidence and record who has authority to rely on that evidence. None of these benefits enters the owner's operating cash-flow ledger.

12 Compare allocation rules against benefit and contribution limits

Five methods allocate the same resource-cost PV of 180. Equal allocation assigns 60 to each region. A load-based rule uses stipulated shares of 50%, 30% and 20%, assigning 90, 54 and 36. Benefit proportionality divides cost in the ratio 110:80:50, producing 82.500, 60.000 and 37.500. These rules answer different distributional questions. The load shares are fictional inputs with no verified connection to actual regional use, demand, peak responsibility or causation. The benefit shares follow the declared weighted-benefit account. Neither rule establishes a legally payable amount without the relevant allocation instrument.

The equal rule leaves regional net benefits of 50, 20 and negative 10. Region C would bear more allocated cost than its weighted benefit of 50. The load and benefit rules both leave positive net benefits for every region in this example. Under benefit proportionality, those surpluses are 27.500, 20.000 and 12.500. A nonnegative net benefit is an individual participation screen under the specified valuation assumptions. It does not establish liquidity, authority to charge customers, willingness to contribute or a funded mandate. It also depends on the scenario weights used to value the benefits.

Separate contribution ceilings are set at 70 for A, 65 for B and 60 for C. They represent hypothetical maximum resource-PV allocations under an assumed mandate. They are distinct from the benefit estimates. The equal rule satisfies all three ceilings even though C has negative net benefit. The load rule exceeds A's ceiling by 20; benefit proportionality exceeds it by 12.500. This combination makes the two screens useful: a benefit-based participation limit and a separately stated contribution mandate can reject different proposals. The model does not infer a contribution ceiling from a benefit estimate.

The ceiling-constrained rule begins with benefit proportions, caps any region exceeding its ceiling and reallocates remaining cost among uncapped regions in their original benefit ratio. A is first capped at 70. The remaining 110 would initially be divided between B and C in the ratio 80:50, giving B more than its ceiling of 65. B is consequently capped at 65 and C receives the remaining 45. The resulting 70, 65 and 45 allocation is budget-balanced, respects all three ceilings and leaves net benefits of 40, 15 and 5. Total ceilings are 195, which exceeds the base resource cost by 15. That aggregate capacity makes this particular capped rule feasible; regional caps and the redistribution rule still determine the final allocation.

This is an expressly conditional allocation, with no assumed authority to increase another region's obligation. The algorithm represents a proposed rule that all relevant parties would have to accept. If a region refuses the redistributed amount, the transaction needs a revised allocation, a lower-cost scope or another authorized source. The model never converts an unresolved share into an automatic public contribution. It also retains the allocation before translating it into an annual owner invoice, so the reader can see where a financial recovery convention changes the burden measured at a common discount rate.

All entries are resource-cost PV allocations at t0; none is an invoice or automatic payer obligation.

13 Test coalition alternatives without claiming a negotiated result

The cooperative-cost diagnostic introduces separate fictional alternatives for serving individual regions or smaller coalitions. Standalone service costs are 120 for A, 95 for B and 75 for C. Joint service costs are 155 for AB, 145 for AC and 135 for BC; service for all three costs 180. These are resource-cost PVs on the same date and at the same 6% system rate. They assume that each stated coalition obtains its specified service. No network topology, service equivalence or permission to build an alternative is established. The empty coalition has cost zero. All seven nonempty coalition values are disclosed so the calculation can be reproduced.

The Shapley allocation averages each region's incremental coalition cost over all six possible joining orders. For order ABC, A contributes 120, B adds 35 and C adds 25. For order CBA, C contributes 75, B adds 60 and A adds 45. Each ordering sums to the grand-coalition cost of 180. Averaging the six marginal-cost vectors gives allocations of 76.667 for A, 59.167 for B and 44.167 for C. Equal weight across orderings is the mathematical convention of this calculation; it is unrelated to the demand-scenario weights and supplies no prediction of a bargaining sequence.

Coalition rationality is tested separately. For each individual and each pair, the assigned aggregate cost must be no greater than that coalition's specified alternative cost. The full allocation must also sum to 180. The model reports slack as alternative cost less assigned cost. Under the Shapley allocation, individual slacks are 43.333, 35.833 and 30.833, while pair slacks are 19.167 for AB, 24.167 for AC and 31.667 for BC. All are positive. This places the allocation within the core of the stipulated transferable-cost game. The result follows from these particular coalition values; Shapley membership of a cost-game core is not assumed as a universal property.

All five candidate allocations happen to pass these coalition inequalities under the supplied cost assumptions. That outcome leaves other screens relevant. Shapley exceeds A's independent contribution ceiling by 6.667. Equal allocation passes the coalition test while C's net benefit remains negative 10, because C's standalone service cost of 75 is itself above its weighted benefit of 50. The cost game assumes a service requirement and compares ways of supplying it. It does not model an unrestricted option for C to abandon that service and incur zero cost. A transaction in which nonparticipation means no service would require that outside option to be specified and valued explicitly.

The calculation consequently supplies a reproducible reference allocation and a set of stated objections. It establishes no empirical fairness ranking, negotiated agreement or nucleolus solution. A proposed bargain still needs its participation rules, service requirement, transferable-payment permissions and actual alternatives. Changes to one pair's alternative can alter coalition rationality even while total project cost and regional benefits remain unchanged. The full coalition table allows that dependence to be tested directly. A decision record should preserve the reason for accepting the alternative costs, since the mathematical result carries their evidential quality into the allocation.

Slack equals stipulated alternative coalition cost less assigned resource-cost PV. Positive slack here satisfies the displayed cost-game inequalities; contribution ceilings and benefit participation remain separate tests. No negotiated outcome is claimed.

14 Carry caps, changing scenarios and recovery rates through the bridge

The cost sensitivity retains benefit weights and the three contribution ceilings while varying resource-cost PV from 140 to 220. At 140, proportional shares remain below all ceilings. As cost increases, successive caps become binding and the residual is redistributed only among regions with unused capacity. At a resource cost of 180 the allocation is 70, 65 and 45. At 195 it is 70, 65 and 60, exhausting all available ceilings. Costs of 200 and 220 leave unallocated residuals of 5 and 25 respectively. Those residuals remain visible and unfunded. The model assigns no default government payer or unilateral right to bill customers for them.

This sensitivity changes a resource-cost total only. It does not claim that every increase consists of financeable capital expenditure or that the original debt facility expands automatically. A transaction would need to classify the additional scope, its timing and the instrument governing recovery. Where the extra cost exceeds authorized contributions, a positive aggregate benefit could coexist with an unclosed funding plan. The next decision would concern the unresolved source, scope revision or allocation approval. The sensitivity exposes that question without assuming which authority can answer it.

A separate weight sensitivity moves from the central scenario entirely to the A-led scenario, sets the C-led weight to zero and keeps total benefit at 240. A's attributed benefit increases from 110 to 150, B's falls from 80 to 60 and C's falls from 50 to 30. Unconstrained benefit allocation correspondingly moves A from 82.500 to 112.500 and C from 37.500 to 22.500. These endpoints demonstrate the distributional effect of choosing weights even when total system value is unchanged. They are alternative author assumptions, with no statistical confidence interval or probability recommendation. The capped rule would require a fresh application if those weighted benefits were adopted.

For the owner cash illustration, the selected resource allocation of 70, 65 and 45 becomes invoice shares of 38.889%, 36.111% and 25%. Capital recovery is an assumed fifteen-year level annuity at a financial rate of 8% on construction cost of 150. This gives annual capital-charge cash of 17.524. Exact reimbursement of annual operating expenditure of 3.089 raises the total annual invoice to 20.613. The invoice shares apply to both components. Operating expenditure is then deducted to obtain owner CFADS. Capital-charge cash represents a stipulated receipt from the regions; the energy, reliability and flexibility benefits remain outside that receipt.

The conversion uses a different recovery rate from the system discount rate, which changes the payment burden measured at 6%. Under full collection, regional invoice PVs at 6% are 77.856, 72.295 and 50.050, compared with resource allocations of 70, 65 and 45. The contribution ceilings therefore certify only the stated resource-allocation metric. They do not certify that these later invoice PVs meet an identical monetary cap. If the mandate instead caps actual payment PV, the owner tariff and allocations must be redesigned and re-tested. At the owner's declared 8% discount rate, full-collection unlevered NPV is zero by the capital-annuity construction, with operating expenditure exactly reimbursed. Financing flows remain excluded from that NPV.

Iteratively cap benefit-weighted allocations and redistribute remaining cost among uncapped regions. Cost above total ceilings remains unfunded.

Table 11. Scenario-weight sensitivity of benefit allocation

Central weight is one minus A-led weight; C-led weight is zero in this separate sensitivity. Total allocation remains 180; no probability recommendation.

Selected ceiling-constrained fractions applied to a stipulated 8% fifteen-year annuity on capex 150 plus exact operating reimbursement; no actual tariff approval.

Benefit-weighted allocations are capped and redistributed among uncapped regions. Total assumed ceilings are 195; costs above that amount leave an unallocated residual. No automatic public or regional residual payer is assumed.

15 Follow missing regional invoices through debt and reserves

The owner finances time-zero construction with debt of 90 and sponsor capital of 60. Debt represents 60% of construction cost alone and amortizes through ten equal end-year payments at 6%. Annual service is 12.228. The sponsor separately deposits a one-payment reserve of 12.228 at time zero, making total initial sponsor funding 72.228. Sources of 90 debt plus 72.228 sponsor cash equal 150 construction plus 12.228 reserve funding. The example has no construction interval, capitalized interest, financing fee or reserve investment return. A reserve deposit supplies liquidity and remains a financing transfer throughout.

With full collection, CFADS of 17.524 gives debt-service coverage of 1.433. The first interruption case permanently removes B's invoices for years 1 and 2. Other regions' invoices remain unchanged and operating costs remain fully payable. B's absent annual payment of 7.444 reduces annual CFADS to 10.081 during those two years. Coverage falls to 0.824. Each debt payment then draws 2.147 from reserve, for a total drawing of 4.295. The initial reserve is sufficient, so fresh operating sponsor funding is zero in that case. Debt is still fully serviced under the assumed reserve permission; the operating coverage measure remains below one during the interruption.

The second interruption case collects those same two missed invoices together with B's ordinary invoice at the end of year 3. Years 1 and 2 have the same reserve use and coverage result. The catch-up cash changes later liquidity and economic loss. Permanent loss reduces owner NPV at 8% by 13.274. Delay until year 3 reduces it by 1.456, calculated as the discounted value of the two originally due payments less the discounted catch-up amount. The delayed case includes no arrears interest or penalty. The two cases share an initial cash shortage but create different permanent receipt totals and dated owner values.

A separate prolonged stress removes B's first seven annual invoices permanently. Reserve drawings reach the full opening amount of 12.228, and fresh sponsor cash of 2.804 is required after depletion. Owner NPV falls by 38.755. That support is an uncommitted, timely equity contribution assumed solely to calculate the funding requirement; the model gives it no fee, interest or repayment entitlement. It never enters CFADS. After scheduled service, excess owner cash replenishes the reserve before distribution. The reserve is released after the final debt payment in year 10. All debt-service calendars remain fixed, and no missing regional payment is silently reassigned to A or C.

The final exposure comparison repeats the two-year permanent B loss under each allocation rule. It shows how choosing B's invoice share changes the owner's concentration exposure, coverage and reserve use, even though total resource cost is unchanged. This is a deterministic consequence test with no default probability. Supporting calculations retain every annual cash row, all six joining-order vectors and the complete coalition inequalities. High-precision Decimal checks reconcile the annuities and owner NPVs; calculated identities reconcile construction sources, debt principal, budget-balanced allocations, capped residuals and loss-versus-delay valuation. Annual cash conservation is checked across every modeled funding path. Actual payment priority, reserve access, enforcement, tax and intrayear timing require separate evidence before applying the illustration to a transaction.

No construction interval, IDC, fees or reserve return. Reserves and debt draws never enter CFADS; all support is uncommitted and assumed timely.

Fictional annual cash. First two B invoices are lost permanently or paid in year 3; first seven lost invoices are a separate stress. Other regions' invoices and debt service stay fixed. Several reserve paths coincide; reserve movements and sponsor cash never enter CFADS. No committed support is established.

16 Make the benefit assessment independently reproducible

A proposed allocation should begin with a data room that lets another reviewer reconstruct how the asset changes outcomes for each region. The opening record would describe the transmission facilities, their proposed commissioning dates and the network conditions used in the comparison. Each benefit calculation should identify the corresponding case without the investment, including the alternative works and operating decisions assumed in that case. A comparison that silently gives the project a more favourable demand forecast or a different outage assumption would need correction before its regional shares enter a payment discussion. The immediate decision is whether the analytical comparison is sufficiently consistent to support an allocation proposal.

The data room should connect each reported benefit to a reproducible calculation and an identifiable recipient category. For an illustrative reduction in generation expenditure, the reviewer would need the dispatch assumptions, affected generation quantities and cost inputs. For a claimed reliability improvement, the record should explain the event being avoided, the modelled consequence and the valuation convention. A transfer between market participants should be recorded separately wherever it overlaps with a claimed resource saving. This proposed classification allows the reviewer to test whether the allocation counts the same underlying improvement through several descriptions. Any unresolved overlap should remain visible in the assessment rather than disappearing inside an aggregate regional total.

Geographic assignment deserves its own evidence trail. A network model may identify changes at nodes or across an interconnected system, while the proposed payer is a regional institution or a customer class. The bridge between these units should specify the aggregation rule, asset boundary and treatment of customers that operate in more than one region. A benefit that cannot yet be attributed credibly should retain that uncertainty. The board could approve further analysis or a provisional negotiating range without treating the unresolved portion as an accepted invoice. A clear distinction between modelled receipt, attributed benefit and nominated payer would make the subsequent recovery discussion easier to audit.

Version control should preserve the evidence available when each allocation was proposed. An updated demand case may change the result even when the engineering scope remains constant. Reviewers should receive a change register showing which input changed, why it changed and which regional outcomes moved as a result. Replacing an earlier spreadsheet without retaining its assumptions would obscure the source of disagreement. The proposed record should also identify inputs supplied by interested parties and any independent checks performed on them. Confidential inputs can be access-controlled, with sufficient methodological disclosure for affected parties to understand the result and challenge a material assumption through an agreed review route.

17 Convert an allocation into a documented payment route

The next proposed decision concerns the legal and cash mechanism through which the owner could collect its allocated cost. A regional percentage identifies an analytical share. The transaction still requires a specified payer, a recognised payment obligation and a method for determining the amount due. The implementation team should prepare a separate recovery schedule for each proposed contributor. That schedule would connect the allocation to the relevant approval or agreement, identify the invoicing party and describe the conditions preceding the first payment. Counsel and the commercial team would need to verify the actual instrument before its receipts entered a committed funding case.

An illustrative region might benefit through lower operating expenditure while the proposed payer collects funds from a different set of customers. The recovery design should explain that relationship explicitly. It should identify any intermediate collection body, the route by which collected amounts reach the asset owner and the treatment of amounts collected late. The model should distinguish a customer charge, cash held by an intermediary and cash available to service the owner's debt. Each stage can have a different approval dependency and credit exposure. Proposed contractual terms should therefore be evaluated against the dated owner cash schedule, with unverified authority or collection capacity retained as an open condition.

The payment basis also needs a defined cost perimeter. A contribution toward construction expenditure may leave financing interest, reserve deposits, operating expenditure, taxes or closure obligations outside recovery. The owner should prepare a reconciliation between the eligible cost base and the complete funding requirement. Each difference should have an identified proposed source of finance or an explicit unresolved funding requirement. This reconciliation is especially important where regions select different payment profiles. An upfront contribution and a stream of later charges should be compared on declared dates and discount conventions, while the financing assessment separately shows who carries the interim cash requirement.

Changes in participation need deliberate treatment. A new customer may enter after the asset is commissioned, an original beneficiary may close a facility, or a region may contest the continuing basis for its share. Proposed agreements should address the evidence and approval route for any reassessment, including whether earlier payments remain settled. The cash model should show the consequences of the proposed reassessment rule without presuming a right to reopen the bargain. If the parties seek a fixed commitment, the agreement would need to state the relevant boundaries and exceptions. A financing decision would require verified treatment of those exceptions and their interaction with debt obligations.

Proposed review matrix. Contractual allocation, counterparty capacity and enforceability require project-specific verification; no universal assignment is assumed.

18 Structure consultation around decisions that can change

A proposed consultation should present the investment choice and its allocation as connected decisions. Participants need enough information to understand what is being built, why the selected scope was proposed and how their assigned share follows from the assessment. The consultation package should distinguish the decision-maker's verified authority from arrangements that remain subject to agreement. Its timetable should identify the approvals required before the owner can rely on a recovery route. No particular consultation duration or entitlement is assumed here. The appropriate procedure depends on the actual instruments, institutions and affected parties, which require project-specific review.

The package should explain which alternatives remain genuinely open. If a sponsor has already placed equipment orders, that commitment may restrict the options available to the decision-maker. The disclosed analysis should identify those commitments and the associated cancellation exposure. An option should remain in the comparison only with a realistic account of how it could still be implemented. For an illustrative disagreement over regional shares, participants could be asked to identify the contested benefit input, the proposed correction and its consequences for the full allocation. This approach would make submissions usable in the decision process without requiring every participant to produce an entirely new network study.

Responses should be assessed through a documented issue record. A technical correction, an objection to the valuation convention and a concern about customer affordability require different analysis. The owner should record the evidence considered for each material issue and explain any resulting change to scope, allocation or payment timing. Where the decision-maker rejects a proposed change, the record should state its reason within the applicable process. These are recommended documentation practices; they establish no procedural right in a particular jurisdiction. The purpose is to show how the final proposal responds to the evidence actually received.

Affordability should be examined alongside the aggregate benefit calculation. A region can have a positive modelled benefit while a particular customer group faces charges before receiving an improvement. The proposal should show the timing and incidence of payments, the identity of the affected group and the basis for any relief or deferred recovery being considered. Deferral creates a funding question for the owner and potentially for another contributor. Any proposed adjustment should therefore appear both in the customer assessment and in the financing model. The allocation should remain reconcilable after the adjustment, with its funding source and approval dependency clearly stated.

The final recommendation should bring the technical proposal, consultation outcome and recovery instruments to the same version. Approval of revised shares against an obsolete cost estimate would leave an avoidable ambiguity at execution. The decision record should identify the adopted study, approved or proposed cost perimeter, payer schedule and unresolved conditions. If a material issue remains open, the recommendation should define the expenditure that can proceed while it is resolved. The practical decision is the extent of commitment justified by the available approvals and evidence, including whether further consultation or a revised agreement is required.

19 Govern regional boundaries and shared interfaces explicitly

The implementation structure should define the boundary between jointly funded transmission facilities and the assets that remain within an individual region's responsibility. A map alone may leave questions about shared substations, protection equipment, control systems and access works. The proposed boundary schedule should assign each relevant asset to an owner, a delivery obligation and an operating responsibility. It should also identify the point at which expenditure becomes eligible for the shared cost pool. This schedule provides a practical basis for deciding which invoices enter the regional allocation and which require a separate approval or bilateral arrangement.

Interface costs need particular attention when one region's local works are necessary for the shared facility to provide its intended service. The allocation proposal should show that dependency, the expected delivery date and the consequence of a delay. A region's contribution to the common line should not silently imply funding for every associated local reinforcement. Equally, omitting necessary local works from the funding plan would overstate the readiness of the overall project. An integrated delivery schedule should connect the critical interfaces while retaining the contractual responsibilities of the separate owners. Any assumption that one party can direct another party's works should be verified.

The proposed governance agreement should identify the decisions requiring joint approval and the matters delegated to the operator or delivery entity. An increase in capacity, a changed terminal location or the admission of another participant may affect regional benefits and cost shares. Routine technical decisions may require a different approval route. The parties should define materiality with reference to consequences for cost, service and liability, using thresholds appropriate to the actual project. A decision log should record the information available, the approving parties and any reservations. The objective is to give the delivery team a usable mandate while preserving the approvals needed for material changes.

Data access should follow the same allocation of responsibilities. Each region may require operating information to validate charges or assess continuing benefits. The proposed agreement should identify the relevant measurements, who maintains them and how errors are corrected. Confidential commercial data may require restricted access, while aggregate information can support wider reporting. The operator should retain enough underlying evidence for an authorised reviewer to test a disputed calculation. The parties should also decide how a revised measurement method enters the agreement, particularly where the revision changes a payment rather than merely improving the presentation of information.

20 Reconcile changes in cost with collection and default exposure

The proposed change-control system should distinguish a revised engineering requirement, a price change within existing scope and expenditure caused by delay or rework. Each category may have a different treatment under the eventual recovery instruments. The commercial team should therefore avoid applying the original regional percentages automatically to every additional invoice. A change request should identify the triggering event, the incremental scope, the cost estimate and the proposed allocation basis. It should also show which party can approve the change and when the related expenditure becomes unavoidable. This record supports a decision on commitment before the payment obligation is incurred.

The benefit assessment may need revision when the change alters capacity or service. A cost increase caused by a more expensive procurement outcome could leave the regional benefit distribution largely unchanged under the stated model. An added connection or different operating configuration could change that distribution substantially. The owner should propose a rule for determining when the study must be rerun and who reviews the resulting allocation. Pending review, the funding plan should identify the party advancing cash and the terms on which reimbursement is expected. An assumed future redistribution should remain separate from an effective payment commitment.

Cost recovery and collection risk should also have separate records. An approved charge can remain unpaid on its due date. The financing model should test the resulting owner liquidity using the actual payment calendar and the proposed reserve and support arrangements. A disputed invoice, delayed intermediary transfer and counterparty failure may have different recovery paths. Proposed security and support should be linked to the specific event they cover, including any conditions on drawing them. The owner should avoid assigning the same liquid resource simultaneously to construction contingencies, debt service and disputed regional payments without showing its permitted uses and available balance.

The consequences for other regions require explicit examination. If one contributor does not pay, the project may need sponsor support, additional borrowing, expenditure deferral or a negotiated redistribution. Each possibility has a different contractual and political burden. The implementation recommendation should identify which responses are actually available and which require further consent. A scenario that assumes other contributors absorb the shortfall should explain the supporting instrument or retain the assumption as a proposed alternative. The model should show both the original payer obligation and the separate source of interim cash, preserving the distinction between liability and liquidity.

21 Turn the allocation decision into monitored execution

Execution should begin with a controlled schedule that connects the agreed allocation to invoices, construction payments and financing conditions. The schedule should identify the instrument supporting each receipt and the evidence needed before it becomes due. A regional approval date may differ from the first collectible payment date, while an equipment supplier may require an earlier instalment. The funding case should retain those dates separately. Before releasing an irreversible commitment, the owner should confirm the relevant approvals, contribution arrangements and available liquidity against the current version of the schedule, recording any conditions that remain outstanding.

The proposed completion record should reconcile the approved asset scope, executed contracts and opening financing position. Any difference from the approved business case should be explained before the governing body accepts the handover into delivery. If a contribution has been reduced, a payment deferred or a security instrument changed during negotiation, the model and approval record should reflect that change. The responsible teams should sign off their own evidence rather than relying on an undifferentiated statement that the transaction is complete. The practical test is whether an independent reviewer can identify who pays each material amount, when it is due and what happens if it is unavailable.

Monitoring should maintain separate views of physical delivery, benefit assumptions and collected cash. A line can be on schedule while the payer arrangements remain incomplete. Receipts can arrive while the expected beneficiary configuration changes. A proposed reporting cycle should therefore reconcile progress against the integrated delivery plan, explain changes to the benefit inputs and compare actual collections with the approved cash schedule. Differences should identify a responsible action and the next decision required. Any forecast recovery dependent on a pending amendment should remain distinguishable from cash already received and from an existing enforceable obligation.

The review process should also preserve settled decisions. Repeatedly reopening an agreed allocation in response to small model updates could make the payment schedule difficult to finance. Conversely, a material change in scope or participation may justify a formal review under the governing instruments. The proposed monitoring protocol should state what information triggers that review and which approvals are required before charges change. Historical reports should remain available so that participants can distinguish a revised estimate from an error in a previous invoice. Corrections, refunds and prospective adjustments should be recorded according to their actual authorised treatment.

The final board memorandum should state the next expenditure decision, its amount and timing, the verified funding available and the material unresolved conditions. It should identify the assessment and contractual versions on which the recommendation relies. Where the proposal depends on further agreement, the memorandum should set out the consequences of failing to obtain it before the commitment date. This closes the connection between regional benefit analysis and executable financing. The recommended monitoring process continues to test that connection throughout delivery and operation, with changes approved through the agreed instruments and unsupported assumptions kept visible to the parties bearing the cash exposure.

22 Turning the reviewed allocation into an investment decision

The proposed investment decision has a defined perimeter and a dated cash requirement. Its approval should distinguish contributions already established by a relevant instrument, amounts awaiting approval, and receipts whose conditions remain unmet. A conditional contribution cannot support the same commitment as an unconditional payment already due. The advisor should identify what changes each amount's classification and who must confirm that evidence. Examples include an approved tariff method, a signed contribution agreement, a satisfied funding condition or a collection secured by a reviewed credit instrument. The existence of those items must be verified for the particular project.

The calculated comparisons show why the choice of allocation formula deserves a documented explanation. An equal share can exceed a region's assumed benefit even when total project benefits exceed shared resource cost. A proportional share can satisfy the assumed individual benefit limit and still raise a different issue about a coalition's available alternative. A contribution ceiling can change the allocation or leave part of the cost without an identified payer. These are distinct tests with distinct denominators. The displayed calculations help an investment committee understand the consequences of its stipulated assumptions; they do not confer a regulatory preference on a formula.

For the same reason, a contribution method that balances its cost pool is only one part of the funding review. A payer's delayed invoice can create an owner cash shortfall on a debt-payment date. A permanently lost payment can also reduce owner value after the initial liquidity problem has passed. The financing schedule retains the original debt obligations in both cases. It reports any reserve use and additional sponsor cash separately from operating cash available for debt service. Those distinctions help the reader locate the actual funding decision rather than assigning a general financing benefit to the selected allocation method.

A real approval should include a table of unresolved matters with specific consequences for expenditure. If the shared-cost estimate lacks an agreed scope, the submission should identify which tender or works package depends on that uncertainty. If an allocation method is disputed, the submission should name the amount exposed to the outcome and any commitment already made. If payment timing is uncertain, the cash schedule should identify the date and size of the unfunded requirement. Such a record allows a board to approve a bounded next step or defer it with a clear reason. It does not require an invented probability for each unresolved matter.

Subsequent monitoring should use the same definitions as the approval. The owner should reconcile actual expenditure, invoices, collections and financing payments while the planning team tracks the agreed system measures. Changes in those accounts need a clear review trigger and the relevant approval route. The analyst should preserve the original case as the baseline and show what has changed in a dated revision. A sponsor can then distinguish a cost estimate error, a system-use change, a billing dispute and a collection failure. Each issue requires evidence and a potentially different contractual or regulatory response.

The framework's principal limitation is the evidence needed to apply it. No actual benefit study, negotiated contribution, approved tariff, executable procurement contract or payment security has been verified for the fictional project. Its scenario weights are illustrative and its coalition costs are stipulated alternatives. The allocation and financing results therefore remain conditional on those inputs. A project-specific assessment would replace each assumption with reviewed material and preserve the same accounting separation, traceable calculations and clear statement of remaining uncertainties.
