Amazon to purchase power generated from Birch Solar project By Sam Shriver - sshriver@limanews.com COLUMBUS — Lightsource bp announced Tuesday that they’ve reached a deal to sell power produced from the Birch Solar farm to Amazon. The 375-megawatt solar farm, proposed for portions of Allen and Auglaize Counties has yet to be approved by the Ohio Power Siting Board, a process that is expected to be completed by the end of the year. According to a news release issued by Lightsource bp, the “facility is expected to deliver nearly 600,000-megawatt-hours annually of additional renewable energy for Amazon operations locally — equivalent to the annual electricity consumption of about 55,000 U.S. homes.”
