The U.S. Department of Energy and the North Carolina Clean Energy Technology Center are excited to announce that a new, modernized DSIRE is under construction. The new version of DSIRE will offer significant improvements over the current version, including expanded data accessibility and an array of new tools for site users. The new DSIRE site will be available in December 2014. Staff are currently working hard on the new version of DSIRE but are also maintaining the content of the current version of DSIRE. Thank you for your continued support and patience during this transition. We hope you are as excited for December as we are!

Summary:

The South Carolina Public Service Commission (PSC) adopted simplified interconnection guidelines for small distributed generation (DG) in December 2006. These guidelines address renewable-energy systems and other forms of DG up to 20 kilowatts (kW) in capacity for residential systems, and up to 100 kW for non-residential systems. Provisions for three-phase generators are not included.

South Carolina's interconnection guidelines apply to Progress Energy, Duke Energy, and South Carolina Electric and Gas.

There is a $100 application fee for residential systems and a $250 application fee for non-residential systems. Utilities may not require residential customers to carry liability insurance beyond the amount required by a standard homeowner's policy ($100,000 minimum coverage), but non-residential generators are required to carry comprehensive general liability insurance ($300,000 minimum coverage). Generators are responsible only for upgrade and improvement costs associated directly with a system's interconnection, but these costs may be determined by utilities. Utilities are prohibited from imposing indirect fees and charges. The guidelines include a mutual-indemnification requirement.

A redundant external disconnect switch is required, and the capacity of all interconnected generation is generally limited to a maximum of 2% of rated circuit capacity.
