1. Frame the wider-grid allocation decision
A transmission project can produce reliability, congestion, resource-access, resilience and option benefits across several pricing zones. The allocation decision must connect each supported benefit to identifiable beneficiaries and a durable recovery route.
The evidence file should identify the governing tariff, planning instrument, system model, cost estimate, benefit calculation and approval authority. Every material input needs an owner, date, source and review trigger so the allocation remains reproducible.
A practical transaction review asks who pays, how much, from when, under which instrument and subject to which adjustment. The answer should support tariff approval, contractual commitment and financeability at the same time.
2. Define the facility and decision perimeter
The record should distinguish local, regional, interregional and cross-border facilities, including shared substations and enabling works. Asset boundaries determine which costs enter the common pool and which remain directly assigned.
The analysis should distinguish measured system effects, scenario outputs and policy judgements. Where monetisation remains uncertain, the decision record should retain the physical metric and explain how uncertainty affects the allocated share.
Allocation becomes executable when the approved cost base, payment obligation, credit support, true-up and dispute route are documented together. The capital structure should use only revenue supported by that enforceable package.
3. Separate cost causation from benefit attribution
Cost causation asks which activity created the need. Benefit attribution asks which customers gain from the selected investment. A defensible method documents both tests and reconciles conflicts between them.
The working model should reconcile project cost, benefits and beneficiary geography under a common set of scenarios. Changes to topology, demand, generation or timing should flow through the same controlled calculation rather than an off-model adjustment.
The board and regulator should see the distribution of value and downside by region before committing capital. The preferred method should remain operable under delay, cost escalation, lower benefits and changes in participant composition.
4. Map the regulatory authority
Jurisdiction over planning, tariffs, siting and consumer protection can sit with different bodies. The allocation design should identify who approves the method, who files it and who resolves disputes.

Beneficiary-pays allocation links charges to estimated benefits and protects customers from unrelated expenditure. Application requires transparent benefit metrics, geographic granularity and treatment of uncertainty.
The analysis should distinguish measured system effects, scenario outputs and policy judgements. Where monetisation remains uncertain, the decision record should retain the physical metric and explain how uncertainty affects the allocated share.
Allocation becomes executable when the approved cost base, payment obligation, credit support, true-up and dispute route are documented together. The capital structure should use only revenue supported by that enforceable package.

This gate tests revenue timing, credit, debt capacity, liquidity and change risk. Financing should reflect the approved allocation rather than an expected future compromise.
The evidence file should identify the governing tariff, planning instrument, system model, cost estimate, benefit calculation and approval authority. Every material input needs an owner, date, source and review trigger so the allocation remains reproducible.
A practical transaction review asks who pays, how much, from when, under which instrument and subject to which adjustment. The answer should support tariff approval, contractual commitment and financeability at the same time.
59. Run the delivery and monitoring gate
This gate confirms contracts, milestones, cost control, reporting and benefit review. It links actual delivery to permitted recovery and future true-ups.
The analysis should distinguish measured system effects, scenario outputs and policy judgements. Where monetisation remains uncertain, the decision record should retain the physical metric and explain how uncertainty affects the allocated share.
Allocation becomes executable when the approved cost base, payment obligation, credit support, true-up and dispute route are documented together. The capital structure should use only revenue supported by that enforceable package.
60. Adopt the decision record and 90-day plan
The final record states scope, benefits, allocation, financing, protections, risk owners and review points. The first 90 days should close the highest-value evidence and agreement gaps.
The working model should reconcile project cost, benefits and beneficiary geography under a common set of scenarios. Changes to topology, demand, generation or timing should flow through the same controlled calculation rather than an off-model adjustment.
The board and regulator should see the distribution of value and downside by region before committing capital. The preferred method should remain operable under delay, cost escalation, lower benefits and changes in participant composition.
Table 4. Illustrative 90-day regional cost-allocation programme
| Period | Workstream | Core actions | Decision output | Accountable owner |
|---|---|---|---|---|
| Days 1-15 | Project and authority | Confirm scope, alternatives, cost base, jurisdictions and approvals | Controlled project definition | System planner and counsel |
| Days 16-30 | Scenarios and models | Reconcile topology, demand, generation, policy and counterfactuals | Approved modelling protocol | Technical adviser |
| Days 31-45 | Benefits and beneficiaries | Quantify benefits, interactions, geography and uncertainty | Auditable benefits register | Economist and independent reviewer |
| Days 46-60 | Allocation | Apply candidate methods, thresholds, true-ups and protections | Preferred allocation statement | Regulators and participant forum |
| Days 61-75 | Financing and documents | Test revenue, credit, debt capacity, liquidity and dispute terms | Financeable payment package | Financial adviser and counsel |
| Days 76-90 | Decision record | Approve shares, conditions, monitoring and escalation | Executable allocation decision | Authorised regulators and boards |
Timing is indicative and should be adapted to the governing planning and regulatory process.
Each gate requires documented evidence before the next capital commitment.
The framework converts a contested policy question into an auditable investment process. It connects project definition, quantified system value and beneficiary geography to an approved method, enforceable payment and financeable revenue.
Execution quality depends on maintaining the evidence after approval. Delivery cost, system use and benefits should be monitored against the same controlled model so that any true-up follows pre-agreed rules.
