Duke Energy Renewables has bought six solar farms in Eastern North Carolina, raising its total in the state to 30 sites.
Terms of the purchase from Community Energy were not announced. Five of the farms are already operating, with the sixth coming online in May.
Together they will have total capacity of 30 megawatts, enough energy to supply about 6,000 homes. Output from the solar projects is being sold to Dominion NC Power under 15-year agreements.
Four of the sites are in Northampton County, with one each in Edgecombe and Hertford counties.
Duke Energy added 300 megawatts of solar energy in North Carolina in 2015. The company has spent more than $4 billion on renewable energy and says it will invest about $3 billion more over the next five years.
North Carolina in March became the nation’s third-largest state for installed solar capacity, the Solar Energy Industries Association says, up from fourth place. California and Arizona rank first and second.
