October 2012 - The U.S. Navy has switched on a 13.78-megawatt (MW) solar array at its Naval Air Weapons Station at China Lake, California. The Navy will purchase the system's power through a 20-year power purchase agreement (PPA) with an affiliate of MetLife, Inc. The project was designed and developed by SunPower. Using a long-term energy procurement authority (U.S. Code Section 2922A), the 20-year solar PPA at China Lake marks the first of its kind for a federal agency.
The array will generate enough electricity to account for 30 percent of China Lake's annual electricity demand and is expected to reduce the Navy's energy costs by roughly $13 million over the course of the agreement.

March 2010 - The U.S. Navy awarded a $200 million contract to five solar development companies for the construction of up to 40 megawatts (MW) of photovoltaic (PV) power plants in the southwestern United States. The companies, SunEdison, AECOM Energy, Solar Power Partners, Inc., SunPower Corporation, SunDurance Energy LLC, and Chevron Energy Solutions Company, will construct, own, operate, and maintain the PV systems, selling power to the Navy and Marine Corps through power purchase agreements. In October 2009, the U.S. Navy established a goal of producing at least 50 percent of its shore-based energy from renewables by 2020.
