SunEdison to sell output from 18 MW plant in North Carolina

June, 2008: Duke Energy Carolinas, the Charlotte, North Carolina-headquartered subsidiary of large US electric utility Duke Energy, confirmed on May 21 that it will purchase the output from what would be the largest PV power plant in the US under a 20-year contract with Maryland-based solar energy provider SunEdison LLC.

The projected start date for the system, which will be »more than 16 MW,« is »no later than Dec. 31, 2010,« according to Duke.

Commissioners in Davidson County, North Carolina – where SunEdison will now install and own the PV plant – approved approximately $2 million in incentives for the company to locate the system in their county. Construction is scheduled to commence in early-October 2009.

According to SunEdison, the total capacity of the plant will actually be 18 MW AC, or 21.5 MW DC, even though Duke has committed to only 16.1 MW AC of that amount. Duke, or another utility operating in North Carolina, may be the intended target for the remaining power. The state last year passed a Renewable Portfolio Standard (RPS) requiring utilities to supply 12.5 percent of their electric demand with renewable resources by 2021. The law, which SunEdison and other US solar industry representatives helped shape, included specific requirements for solar-generated electricity beginning in 2010. According to the North Carolina Sustainable Energy Association, the law is expected to result in approximately 30 MW of solar power in 2010 and 300 MW by 2018.

If built, the proposed plant would be the largest in North America – ahead of the 14 MW plant at Nellis Air Force Base in Nevada, built by SunPower Corp., and SunEdison's own 8.2 MW plant in Colorado. SunEdison in late April broke ground on a 19 MW solar farm in Ontario, Canada.
