Renewables & Customer Generation

Greenville Utilities supports innovative ways to use and conserve energy sources that protect our environment. 

Renewable energy resources, such as wind and solar energy, are playing an increasingly important role in meeting the nation’s energy needs. Today, there are many renewable technologies that are commercially available to homeowners and businesses that can be safely interconnected to our electrical grid. These resources are important to GUC’s balanced approach to meeting our region’s growing electrical needs and helping to establish a cleaner energy future. Customers may sell the total output of their renewable energy resources to Greenville Utilities depending on the system size and meter arrangement.

The system size limitations are:

  • Residential Customers up to 20kW-AC
  • Commercial Customers up to 500 kW-AC

(For Systems >500kW a Purchase Power Agreement with North Carolina Eastern Municipal Power Agency (NCEMPA) needs to be obtained along with project coordination with GUC).

The Net Billing (Renewable Excess Energy Buy Back Bi-Directional) Metering Arrangement is available to residential customers planning to install a renewable generation system of 20kW-AC or less. This metering arrangement allows for generated energy from the renewable system to help in offsetting the amount of energy consumed from GUC. It also allows for the renewable system to have battery storage.
