Virtual PPAs and Sleeved PPA Transactions: a Primer

November 10, 2023 – In recent months, Centennial's corporate and industrial customers have increasingly asked for Sleeved PPAs and, in some cases, Virtual PPAs.  

Sleeved PPA Structure

Sleeved PPAs often involve a direct Power Purchase Agreement (PPA) between the corporate offtaker and the solar project company.  The offtaker usually enters into associated arrangements, which are either managed by the offtaker itself or via a utility or other load-serving entity, to enable the output purchased to be used for the benefit of the offtaker's off-site facility load. 

Virtual PPA Structure

Whereas, Virtual PPAs are a financial derivative under which the parties agree a strike price, with payment flows being determined by comparing that strike price against a market reference price. They do not involve the physical delivery of output to the buyer or a utility agent of the buyer.
