Rooftop Solar

Distributed generation (DG) is the term we use for small generation equipment located around Tri-County EMC’s distribution system. Distributed generation can be gasoline, diesel, or propane fueled engines, solar (PV), wind, micro-turbines or fuel cells. For distributed generation located at a home or business, Tri-County EMC requires the following:

  • A double throw transfer switch is required to isolate the generator from Tri-County EMC’s distribution system if the DG device is to be used only for emergency backup. Failure to install a double-throw switch can result in injury or death of utility employees or the public and can also lead to damage to your generator.
  • If you intend to operate your DG device in parallel (connected to) with Tri-County EMC’s distribution system with the intent to sell energy to Tri-County EMC, you must complete the Net Metering & Interconnection Agreement.
  • Consult with Tri-County EMC personnel prior to the installation of DG equipment. Prior to the physical connection of any DG, a Tri-County EMC representative will inspect for proper installation and operation.

Selling Energy to Tri-County EMC

The term we use for selling energy back to the utility from your DG system is “net metering”. This term is used because each month’s actual bill is the difference between the energy metered and purchased from Tri-County EMC, at the applicable standard rate, and the energy sold back to the cooperative, which is purchased at an avoided wholesale energy cost rate. Tri-County EMC uses a bi-directional meter to record energy usage from both directions.

Tri-County EMC will purchase DG energy at the Net Metering Rate from residential systems up to 10kW and commercial systems up to 100kW. The total committed capacity of all generators cannot exceed 0.2 percent (0.2%) of Tri-County EMC’s annual peak demand for the previous year.
