First used with wind projects, a pgPPA manages weather-related risk by settling a facility’s energy transfer based on a proxy generation index, rather than on actual metered generation. Operational risk shifts from buyer to seller.
“We were delighted by the contribution [vPPAs] made to our sustainability goals but were frustrated by the financial volatility of the settlement payments and the limited ability we had to predict or manage that volatility,” wrote Kenneth Davies when he was director of energy portfolio management at Microsoft. Working with insurer Allianz and analytics firm REsurety, Davies came up with solutions including the proxy generation PPA, the volume firming agreement and the settlement guarantee agreement.
Data management company Iron Mountain has layered additional hedge contracts onto virtual power purchase agreements that it signed with two wind farms in 2016 and 2017 as it seeks to mitigate various risks associated with the popular renewable energy contracts.
