March 2013 - Wal-Mart has completed the installation of more than 4.5 megawatts (MW) of solar panels atop twelve Ohio stores. The project is expected to produce 6 million kilowatt-hours (kWh) per year—approximately 10-15 percent of each store's power consumption. The systems are owned and operated by SolarCity, which will sell the electricity to Wal-Mart through a negotiated power purchase agreement. The new solar installations account for nearly a tenth of all the solar currently installed in Ohio. Currently, Wal-Mart has 240 renewable energy projects underway worldwide, including three recent solar installations completed in Kahului, Kailua-Kona, and Kapolei, Hawaii. The Hawaii installations each have a capacity of 311 kilowatts (kW) and are expected to individually produce 400,000 kWh annually.
