Electricity is flowing into the Greeneville Light & Power System grid from two solar farms in Tusculum and in Greene County.Testing began at the Silicon Ranch solar farm off Ball Road and another company-operated facility the middle of the month, and the two facilities linked into the power grid shortly after, says Chuck Bowlin, president and CEO of the utility.The other operational site is on Liberty Hill South Road off Old Snapps Ferry Road in an unincorporated section of Greene County.
