A large solar project built to meet the needs of a major aerospace and defense contractor is also providing electricity for Arkansas electric cooperatives.
The utility-scale 12.5-megawatt array serves a manufacturing and testing facility operated by Aerojet Rocketdyne Holdings in East Camden, Ark. With an annual output capacity of 16.8 MW, the power is primarily used for plant operations. But builder Silicone Ranch Corp. has a power purchase agreement with Arkansas Electric Cooperative Corp. to buy the balance.
Little Rock-based AECC estimates the facility will annually provide approximately 20,000 MWh of excess energy that will be wheeled into the wholesale market. Officials at the G&T said the actual amounts of power for purchase could vary based upon manufacturing plant operations and local weather conditions.
“This innovative partnership benefits electric cooperative members by providing predictable energy costs and contributing to the strong economic growth in the Camden area,” said Duane Highley, AECC’s president and CEO. He said they’re “constantly evaluating energy sources to ensure that our 17 retail distribution cooperatives and their more than 1.2 million members have reliable electricity that is affordable.”
East Camden is served by Ouachita Electric Cooperative Corporation whose technical and engineering staff provided consulting services to Silicon Ranch throughout development of the project.
Mark Cayce, general manager of Camden-based Ouachita EC, said such projects help keep electricity rates affordable for members and promote economic growth in the co-op’s service territory.
System testing of the more than 151,000 solar panels and other components began late last year and the single axis ground mounted pedestals reportedly worked well.
“With the unusually sunny Arkansas winter we have been witness to the exciting potential solar has in Arkansas,” said Gary Vaughan, Aerojet Rocketdyne’s director of production operations.
The facility was formally commissioned during a brief ceremony March 31. Arkansas Republican Senators John Boozman and Tom Cotton attended the event along with Rep. Bruce Westerman, R-Ark.
