S.C. Code Ann. § 48-52-635

Pursuant to Section 48-52-630, an agency's savings realized in the prior fiscal year from implementing an energy conservation measure as compared to a baseline energy use as certified by the State Energy Office, may be retained and carried forward into the current fiscal year. This savings, as certified by the State Energy Office, must first be used for debt retirement of capital expenditures, if any, on the energy conservation measure, after which time savings may be used for agency operational purposes and where practical, reinvested into energy conservation areas. The agency must report all actual savings in the energy portion of its annual report to the Office of Regulatory Staff.
