Can you follow the money and responsibility through the contract?
Separate market value from contract cashflow, then test authority, fees, deductions, performance and exit.
Lesson 1 of 5
Define the mandate
List every market action the optimiser can take, every physical limit it must respect and who can override it.
Authority can include wholesale trading, BM submissions, service tenders, nominations and imbalance management. Define asset constraints, warranty envelope, state-of-charge reserves and safety overrides.
Set change-control and emergency authority. An EMS instruction path should match the legal mandate.
Hostile check
Broad discretion with vague physical constraints can transfer degradation and performance risk back to the owner.
Lesson 2 of 5
Choose the commercial model
Merchant share, fixed fee, floor, toll and hybrid structures allocate upside, downside and control differently.
A revenue share aligns gross-market upside but can reward turnover rather than margin. A floor provides downside protection subject to definitions and credit. A toll transfers dispatch economics for a fixed payment while preserving technical obligations.
Identify which market incomes sit inside the contract and which remain with the owner.
Hostile check
Calling a floor guaranteed revenue is unsafe until exclusions, deductions and counterparty security are tested.
Lesson 3 of 5
Build the settlement waterfall
Start with market receipts and payments, then apply energy costs, pass-throughs, fees, shares, floors and true-ups in contract order.
Define data sources, sign convention, settlement timing, revisions, tax and invoice dispute. Track who funds collateral and negative cash periods.
Reconcile public market data with operator statements while respecting portfolio allocation and private trade boundaries.
Hostile check
A fee quoted as a percentage can apply to gross receipts, positive margin or owner cashflow, producing very different outcomes.
Lesson 4 of 5
Test performance and incentives
A benchmark needs an observable opportunity set, feasible constraints and a remedy for underperformance.
Define availability assumptions, forecast horizon, transaction costs, degradation and service commitments. Exclude impossible perfect-foresight comparisons unless clearly labelled as analytical bounds.
Balance performance incentives with penalties for warranty breach, service failure and data-quality problems.
Hostile check
An optimiser cannot be fairly benchmarked against information that was unavailable when decisions were made.
Lesson 5 of 5
Audit risk, credit and exit
The contract must survive market-rule change, system failure, counterparty distress and transfer of the asset.
Review credit support, liability caps, cyber and data obligations, force majeure, change in law, exclusivity, assignment, termination and transition assistance.
Ensure the owner can retrieve data, credentials and operational control at exit.
Hostile check
A strong floor from a weak counterparty can be less valuable than a lower secured payment.

Detailed Course · 75 to 90 minutes
Audit the optimiser agreement as an operating system
Map who can act, what is measured, how cash settles and which risks remain with the owner.
Module 1 of 9
Map control and responsibility
Create a RACI for bidding, nominations, physical dispatch, service qualification, maintenance, safety and compliance.
Align contractual authority with EMS, PPC, BMS and market interfaces. Define command priority and safe fallback. Record owner consent rights for unusual duty or new products.
Allocate consequences for unauthorised dispatch, missed instructions and stale constraints.
Hostile check
Responsibility without the data or control needed to perform it creates an unmanageable risk gap.
Module 2 of 9
Specify data and audit rights
Settlement and performance depend on timely access to market, meter, telemetry, bid and control data.
Define ownership, retention, timestamp, quality, correction and export formats. Provide owner audit rights and independent verification while protecting legitimate portfolio confidentiality.
Set cyber, access-control, incident and business-continuity requirements.
Hostile check
A monthly PDF cannot support a detailed benchmark when dispatch and settlement occur at sub-hourly resolution.
Module 3 of 9
Compare commercial structures
Each structure should be evaluated on cashflow boundary, risk transfer, control and counterparty credit.
Merchant share preserves exposure. A floor limits downside with conditions. A toll fixes owner cashflow while the toller captures dispatch value. Hybrids can add caps, collars or performance shares.
Model the same market scenarios under each structure, including collateral, tax and termination value.
Hostile check
Comparing headline annual payments without option value and exclusions can select the weaker contract.
Module 4 of 9
Write the settlement waterfall
Every cashflow must enter once, in a defined order, with a source and revision rule.
Map wholesale, BM, imbalance, services, Capacity Market, energy purchases, fees, charges and taxes. Define portfolio allocation and transfer pricing. State whether negative components can carry forward.
Include provisional invoices, settlement revisions, dispute windows and final reconciliation.
Hostile check
Unspecified allocation lets a portfolio optimiser move value between assets in a way the owner cannot audit.
Module 5 of 9
Interrogate floors and guarantees
Protection depends on eligible revenue, exclusions, owner obligations, measurement period and security.
Check annual or monthly testing, make-whole timing, caps, carry-forward, change in law and availability adjustments. Determine whether Capacity Market and insurance receipts offset the guarantee.
Review parent guarantee, collateral, letter of credit and termination payment mechanics.
Hostile check
A floor tested only at year end can leave the owner funding a long working-capital shortfall.
Module 6 of 9
Design a feasible performance benchmark
The benchmark should reproduce decisions with information available at the time and the same asset constraints.
Define forecast data, decision gate, liquidity, bid-ask spreads, market impact, efficiency, degradation and concurrent service obligations. Use an agreed independent calculation.
Specify tolerance, review, cure and compensation. Avoid metrics that reward gross turnover at the expense of net value.
Hostile check
Perfect foresight can be reported as an upper bound, while it is unsuitable as the sole contractual performance test.
Module 7 of 9
Allocate operational and compliance risk
Market penalties, imbalance, service non-delivery, warranty use and safety constraints need explicit ownership.
Link each loss to control, causation and evidence. Define liability caps and carve-outs. Set process for grid or OEM constraint updates and optimiser acknowledgement.
Coordinate insurance and indemnity so the same risk is neither uninsured nor assumed twice.
Hostile check
Assigning all service penalties to the owner while the optimiser controls bids creates weak incentive alignment.
Module 8 of 9
Plan change and exit
Long-term contracts must adapt to new products, settlement reform, ownership change and technology updates.
Define change-in-law pricing, new-market approval, system upgrades, assignment, lender step-in and termination. Require data and control transition, credential revocation and parallel-run support.
Test termination payments under both owner and optimiser default.
Hostile check
An owner can regain the asset but remain operationally stranded without data, market access and control transition.
Module 9 of 9
Ashdown worked contract audit
The case converts a headline floor into an effective downside-protection calculation.
Ashdown's 50 MW contract states a £60,000/MW annual floor, equal to £3.0 million. Capacity Market income of £0.25 million sits outside the floor. Pass-through costs of £0.35 million are deducted before the make-whole. Owner-caused unavailability of 5 percent scales the floor to £2.85 million.
Eligible net market revenue is £2.2 million. The preliminary make-whole is £0.65 million, producing £2.85 million inside the floor plus £0.25 million Capacity Market income. Credit support is capped at £0.5 million, leaving £0.15 million unsecured.
Adjusted floor£2.85m
Make-whole£0.65m
Unsecured£0.15m
Hostile check
Quoting £3.25 million guaranteed cash ignores availability adjustment, costs and the unsecured portion of the make-whole.
