Large electricity consumers such as Apple or DuPont have limited options for directly purchasing green power. End-user consumers can’t easily contract with renewable power generators; they have to work through electric utilities who act as intermediaries. This gives utilities excessive market power as the only potential buyers in the green power market.
Based on a model proposed by WRI, Google set a new precedent in the green power market by committing to a long-term Power Purchase Agreement (PPA) with an Iowa wind farm. This is the largest, longest-term wind deal ever closed in the country between a renewable generator and an electricity end-user, and was only possible because of its creative deal structure.
WRI has been actively engaging Green Power Market Development (GPMDG) companies, including Google, for several years to overcome barriers in the power markets and regulations that make it difficult for non-utilities to sign PPAs. Long-term PPAs are essential for renewable power generators, because they are needed to secure financing—yet the traditional model used by utilities is not suitable for electricity consumers.
WRI provided analysis and connections to technical experts that helped Google better understand the benefits of entering into long-term purchase agreements with wind developers. These long-term agreements help the wind developer secure more attractive financing than traditional short term purchase agreements do, while providing important price stability to the end user (the price of wind does not fluctuate). These contracts can be complex to structure and raise many technical and financial questions. WRI’s research helped Google find a workable approach to these contracts that can now be replicated in the market place. This model could increase the amount of wind power the commercial and industrial sector purchase.
The model created by the groundbreaking Google deal will open the door for private electricity consumers to sign long-term PPAs, creating a whole new stream of credit-backing and access to financing for renewable power generators.
