Power Purchase Agreement Structures for Corporate Clean Energy Buyers
Corporate clean energy PPAs exceeded 50 GW globally in 2025, with evolving structures including VPPAs, physical PPAs, and aggregated deals driving solar prices of $25-$40/MWh.
Corporate power purchase agreements (PPAs) have become the primary mechanism for large companies to procure clean energy, with over 50 GW of corporate PPAs signed globally in 2025 alone. The structures have evolved significantly from simple fixed-price contracts to sophisticated instruments that manage price risk, ensure additionality, and provide 24/7 clean energy matching.
Virtual PPAs (VPPAs) remain the most common structure for large corporate buyers. In a VPPA, the corporation agrees to pay a fixed price for the output of a renewable energy project, receiving renewable energy certificates (RECs) and a settlement payment based on the difference between the fixed and market price. This structure allows companies to procure clean energy from projects in different grid regions without physically receiving the electrons.
Physical PPAs, where the buyer takes delivery of electricity at a specific interconnection point, are gaining traction as companies seek closer alignment between clean energy procurement and actual consumption. Google's strategy of matching clean energy supply with demand on an hourly basis has raised the bar for corporate procurement, driving development of more sophisticated matching and procurement tools.
The pricing landscape for corporate PPAs has shifted. Fixed prices for solar PPAs in competitive markets range from $25-$40 per MWh, while wind PPAs typically range from $20-$35 per MWh. Hybrid structures combining solar and storage offer dispatchable clean energy at $40-$60 per MWh. Some buyers are willing to pay premiums of $5-$10 per MWh for projects with specific attributes such as domestic content, community benefits, or 24/7 matching.
Aggregated PPAs, where multiple smaller buyers pool demand to reach the scale needed for utility-scale procurement, have opened the corporate clean energy market to mid-size companies. Platforms like LevelTen Energy, Schneider Electric's NEO Network, and Google's Clean Energy Direct Connect facilitate these aggregated transactions.
