Corporate PPA volumes fell 10% in 2025, and Renewabl CEO JP Cerda says uncertainty around pending scope 2 accounting changes are causing some buyers to hold off. A shift to hourly matching should see battery storage center stage.
Greenhouse Gas Protocol revision may be cooling demand for solar corporate PPA deals, but there is a chance deal volume will spring back when more certainty returns.
Corporate PPA deals were down 10% in 2025 according to BloombergNEF, and JP Cerda, CEO of online energy attribute certificate (EAC) and PPA trading platform Renewabl, told pv magazine the reason might be proposed changes to the Greenhouse Gas Protocol.
Cerda argued the pending update to scope 2 guidance, which governs how companies account for the renewable electricity they consume, has introduced enough uncertainty to put a dent in corporate PPA activity. Proposed changes to the GHG Protocol include taking a more granular approach to carbon accounting, potentially placing new hourly matching obligations onto corporates.
“Corporates are kind of waiting on the final decision on the protocol to see what kind of rules are going to be imposed on them,” he said.
