Platts proposes to launch US PPA price assessments for long-term solar contracts in PJM

Platts, part of S&P Global Energy, is proposing to launch daily Power Purchase Agreement (PPA) price assessments for long-term solar contracts in a number of hubs in PJM, effective May 8, 2026.

The assessments would focus on PPA prices for physical and virtual long-term contracts for electricity power generated from solar projects across three hubs in PJM.Platts defines long-term as PPAs for a tenure of 120 months or longer.

On Jan. 1, the long-term contracts would roll forward to the following year. For example, on Jan. 1, 2027, Platts would start assessing tenors from January 2028.

The published value would reflect virtual PPAs, financially settled, as the basis. Platts would normalize all PPA data to this standard for assessment purposes.

The proposed assessments are listed below:

• PJM AEP-Dayton Hub Solar Long-Term As-Generated PPA Index
• PJM Dominion Hub Solar Long-Term As-Generated PPA Index
• PJM West Hub Solar Long-Term As-Generated PPA Index

The price assessments would also reflect PPA projects for solar technology with an electricity generation capacity of at least 20 megawatts (MW), and contracted on an as-generated basis with a timestamp of 1330 CT. These assessments would be published in US dollars/megawatt-hour (MWh) and follow the US holiday calendar.

The long-term solar assessments would be assessed as bundled products, reflecting energy and Renewable Energy Certificates (RECs) together.

Platts would consider bids, offers and trades for PPAs using these specifications, including information from our partner REsurety and its CleanTrade platform.

Platts would also publish monthly averages for the assessments listed above. The daily assessments would be found on the alert page CLE0002, and the monthly averages would be available on CLE0007.
