The central idea
How do generators manage electricity price risk?
A PPA does not eliminate risk; it changes the combination of risks borne by the producer and buyer.
A PPA does not eliminate risk; it changes the combination of risks borne by the producer and buyer. The public preview explains the operating logic, professional relevance and boundaries before the complete guided application.
Professional relevance
Why this matters beyond the classroom.
Developers secure revenue traders shape and balance buyers manage energy cost and claims
What you will learn
Four lessons that build one working mental model.
- 01
Merchant Exposure and Hedge Objectives
Spot/forward exposure, tenor, hedge ratio, price floors, collars and the difference between revenue certainty and value.
A generator earns value from metered electricity, market settlement, certificates and any other services. Without a hedge, future revenues depend on production, hourly prices, location, imbalance and operating availability. “Merchant exposure” is therefore a vector, not one price. A project can be fixed against a day-ahead index yet remain exposed to profile, basis and imbalance. The hedge design begins by mapping the unhedged cash flow interval by interval. Identify volume, settlement point, price index, currency, time profile, balancing responsibility, certificates, curtailment and taxes/fees. Then choose which uncertainty the project or buyer wants to exchange for contractual obligations. A contract creates new exposures: counterparty credit, collateral, termination, legal interpretation and operational compliance. The correct question is not whether risk disappears, but which party can manage each risk at lowest sustainable cost. A hedge can protect a minimum revenue, support debt service, reduce earnings volatility, secure energy cost for a buyer or demonstrate renewable sourcing. These objectives are related but not identical. A project may hedge only the debt tenor or a percentage of expected production while retaining merchant upside. Hedge ratio compares contracted quantity with the relevant expected or risk-case exposure..

PPA Structures
Physical and virtual PPAs, pay-as-produced, baseload/shaped volumes, fixed price, certificates and route-to-market.
A two-way CfD sets a strike and reference. When reference is below strike, the generator receives the difference for eligible quantity; when reference is above, it pays back the difference. Public CfDs are support instruments awarded under a scheme, while private financial contracts can have similar arithmetic but different legal and policy purposes. Design details include eligible technology, competitive award, reference market, quantity, duration, indexation, negative-price rules, curtailment, clawback, termination and revenue redistribution. An hourly reference gives different incentives from monthly or technology-weighted references. Capability or yardstick designs can differ from injection-based settlement. EU electricity market design rules establish principles for specified direct price support schemes, but national implementation and award documentation determine a particular project. Never describe a generic two-line formula as the complete legal regime. Assume an eligible quantity of 10 MWh, strike EUR70/MWh and reference EUR50/MWh. The support payment is (70-50)x10 = EUR200. If the reference is EUR95/MWh, the generator pays (95-70)x10 = EUR250 under a symmetric two-way structure. Suppose the project actually captures EUR45/MWh when the reference is EUR50. Physical market revenue is EUR450, CfD support EUR200, total EUR650 or EUR65/MWh, not EUR70, because a EUR5/MWh negative basis.

CfDs and Settlement Mechanics
Two-way settlement, reference and strike prices, public support versus private contracts, negative prices and basis.
Curtailment can be caused by grid instruction, connection limitation, economic dispatch, support rules or buyer direction. The PPA should determine whether curtailed energy is eligible, deemed, compensated, excluded or subject to mitigation. Metering alone cannot show counterfactual generation, so deemed-energy methodology matters. Negative-price clauses may suspend fixed-price payment after a duration, require shutdown or allocate lost certificates. The producer may still face technical minimums, forecast positions or grid obligations. A buyer should not direct curtailment without considering who controls the plant and bears resulting losses or warranty effects. Model negative-price frequency and clustering, not only annual count. Curtailment can improve capture price by removing negative-value MWh while reducing volume; evaluate both. The contract price is not simply LCOE plus margin or the forward baseload curve. It reflects expected capture, profile and imbalance costs, credit, collateral, tenor, liquidity, optionality, certificates, curtailment allocation, transaction cost and competitive bargaining. A buyer values correlation with load and budget objectives. Start with an hourly merchant case. Subtract or add expected contract settlements and operating/transaction consequences. Calculate producer NPV and buyer expected cost across scenarios. Separate fair-value analysis from strategic willingness to pay. Long-dated illiquid prices.
- 04
Risk Allocation and Bankability
Volume, profile, shape, imbalance, basis, change-in-law and credit risk; collateral, termination, lender controls and merchant tails.
Long-term energy contracts contain explicit and implicit options. Volume tolerances, extension rights, price reopeners, curtailment direction, substitution assets, assignment, early termination and change-in-law adjustments all affect value. An option exercisable by the buyer is not economically neutral merely because it appears outside the price clause. The financial model should represent who chooses, when, under what trigger and with what consequence. Operational flexibility also has value. A producer that may curtail during negative prices, redirect surplus to storage or sell ancillary services holds optionality. Broad buyer consent or exclusivity rights can remove it. Conversely, a buyer allowed to reduce offtake after load closure can leave the project merchant at the worst time. Each right should be tested under scenarios where exercise is economically rational for its holder, not under the base-case assumption that nobody uses it. Amendments often arise when COD slips, grid conditions change, financing requires bankability provisions or corporate demand evolves. A price concession may be exchanged for tenor, security or volume change. Evaluate the entire amendment package through incremental NPV, DSCR, collateral and residual risk. Never compare only the revised headline price. Renegotiation governance should specify authority, valuation.
Key takeaways
What should remain after the details.
- Uncontracted quantity, mismatch, basis, imbalance, credit and contract conditions.
- Bilateral labels do not route named electrons.
- The authored source identifies “commercial delivery within market roles” as the correct interpretation.
- Strike and realised project revenue diverge when basis exists.
- The authored source identifies “eligible metered project output” as the correct interpretation.
- The authored source identifies “hourly surplus/shortfall exposure” as the correct interpretation.
- A profitable hedge can create severe liquidity demand.
- The authored source identifies “requires generator payback for eligible settlement” as the correct interpretation.

Worked reasoning
Worked CfD settlement
Assume an eligible quantity of 10 MWh, strike EUR70/MWh and reference EUR50/MWh. The support payment is (70-50)x10 = EUR200. If the reference is EUR95/MWh, the generator pays (95-70)x10 = EUR250 under a symmetric two-way structure. Suppose the project actually captures EUR45/MWh when the reference is EUR50. Physical market revenue is EUR450, CfD support EUR200, total EUR650 or EUR65/MWh, not EUR70, because a EUR5/MWh negative basis remains. If capture is EUR55, total becomes EUR750 or EUR75/MWh. This example demonstrates why strike price is not necessarily realised revenue. Quantity eligibility, basis, imbalance, fees and availability change the result.
