Ppa Agreement: What Developers and Buyers Must Get Right

A PPA agreement is built on four foundational legal components. Developers and buyers entering PPA agreement negotiations should seek energy project finance legal counsel to evaluate the regulatory framework applicable to the specific project and structure the agreement to satisfy both lender requirements and offtaker risk parameters.

The pricing structure of a PPA agreement is the most commercially significant element of the deal, and the most common reference benchmark in indexed structures is the day-ahead locational marginal price in the relevant electricity market, plus or minus a negotiated adder. Fixed-price PPAs set the price per megawatt-hour at a predetermined level for the entire contract term, eliminating market risk for both parties. Developers and buyers negotiating PPA pricing should seek energy capital markets legal counsel to evaluate the revenue certainty, financing implications, and market risk profile of each pricing structure.

PPA agreements for renewable energy projects typically address the intermittent nature of solar and wind generation through capacity obligations and availability guarantees. Economic curtailment, where the buyer directs the generator to curtail output because electricity prices are negative or near zero, is a significant risk for renewable generators that must be addressed in the curtailment and payment provisions of the PPA. Generators negotiating capacity and curtailment provisions should seek renewable energy project legal counsel to evaluate the financial impact of curtailment risk and structure the curtailment compensation provisions to protect project revenue.

A PPA agreement cannot deliver electricity without a valid interconnection agreement with the relevant transmission system operator. Network upgrade costs can range from negligible to hundreds of millions of dollars depending on the project's location relative to existing transmission infrastructure. Developers negotiating interconnection terms in connection with PPA agreements should seek energy and infrastructure legal counsel to evaluate the interconnection queue position, model the expected upgrade cost exposure, and ensure that the PPA's conditions precedent and construction timeline provisions are consistent with the anticipated interconnection timeline.

Force majeure provisions in PPA agreements excuse a party's performance obligations when an event beyond reasonable human control prevents performance. Parties negotiating force majeure and risk allocation provisions in PPA agreements should seek energy and environmental law legal counsel to evaluate the risk profile of the specific project, the applicable jurisdiction's treatment of renewable generation events, and the impact of broad versus narrow force majeure definitions on the project's bankability.

FERC regulates wholesale electricity transactions under the Federal Power Act, and market-based rate authority from FERC is required for any generator that sells power at negotiated market prices rather than at cost-of-service tariff rates. Utility-scale and corporate PPA developers and buyers operating in multiple states should seek energy regulatory enforcement legal counsel to assess the federal and state regulatory approvals required for the specific PPA structure and to avoid the market manipulation and anticompetitive conduct prohibitions that FERC enforces.

PPA agreements distinguish between termination events that constitute a party default and termination events that entitle either party to terminate without fault. The consequence of a generator default is typically payment of a termination payment calculated as the present value of the buyer's expected damages from losing the PPA's below-market pricing, often expressed as a fixed liquidated damages amount per megawatt of contract capacity. Parties negotiating termination and liquidated damages provisions should seek energy and infrastructure projects legal counsel to ensure the liquidated damages provisions accurately reflect anticipated harm, are enforceable under applicable state law, and are consistent with lender requirements for the project financing.

Arbitration is preferred in PPA disputes for its confidentiality, the ability to select arbitrators with energy industry expertise, and enforceability of awards across jurisdictions under the New York Convention. Most utility and commercial PPA agreements specify arbitration under AAA or JAMS rules as the exclusive dispute resolution mechanism, with a defined timeline and a panel of three arbitrators. Parties in PPA agreement disputes should seek energy transition legal counsel to evaluate the dispute resolution clause, assess whether the dispute requires expert determination or full arbitration, and develop a strategy that protects the commercial relationship while pursuing the party's contractual rights.
