    Joint Corporate Renewable Energy Procurement

    Expanding business access to renewable energy through aggregation.

    As the cost of renewable energy has plummeted, more than 125 major corporations have set 100% renewable energy targets. Yet businesses looking to procure renewable energy still face a major obstacle: only the largest companies have the expertise and economies of scale to access the largest, most economic projects. In response, in 2019, a group of BC3 member companies completed a groundbreaking aggregate Virtual Power Purchase Agreement (VPPA) deal, which enabled 42.5MW of a 100MW solar farm to be built in North Carolina. This project served as a blueprint for other companies to collaboratively procure renewable energy.
