The U.S. Department of Defense and military branches aim to obtain 25% of their energy from renewable sources by 2025. They are pursuing larger renewable energy projects through aggregated solicitations and a "systems installation" approach. This involves a combination of on-site and off-site generation, micro-grids, and potentially energy storage. While it creates opportunities for developers, it also presents challenges related to government contracting timelines, approvals between multiple agencies, and guaranteed energy purchase levels. Developers must ensure adequate protections are in place for underperformance given the government's inexperience with renewables projects and third-party financing.
