Cary software developer SAS will double the size of the solar farm on its corporate campus.
The company said today it will build a 1.2-megawatt addition, enough to power about 200 homes, to the existing 1-megawatt facility that began operating in December. The new solar project is scheduled to begin generating electricity in March.
When combined, the 2.2-megawatt SAS solar project will constitute the state's biggest solar energy farm. However, Charlotte-based Duke Energy is in the process of building a 16-megawatt solar farm, which will be one of the biggest solar farms in the nation.
The grass growing on SAS's 12-acre solar farm will be grazed by sheep -- an increasingly accepted environmental practice at solar energy facilities.
Progress Energy has contracted to buy the electricity from both SAS solar farms. The Raleigh-based utility is buying solar power and other forms of renewable energy to meet the state's green mandates.
