The Energy Cooperative (TEC) recognizes that Members may be interested in purchasing and operating small renewable powered generating systems to provide electricity to their home or business.  However, there are formal rules for interconnections between small customer-owned generators and electric utility providers.  TEC’s primary concern is that these systems be interconnected safely in accordance with all applicable codes and regulations, without adversely affecting TEC’s electrical utility system.  Interconnection requirements for systems up to 25 kW are covered by the Technical Requirements for PURPA Interconnections are available online or by calling 1-800-255-6815.


  • Renewable generation (RG) systems include wind turbine generators, solar photovoltaic panels, biomass from animal waste, fuel cell, or other qualifying renewable energy generating systems as defined by PURPA.
  • Wind systems utilize a wind turbine collects kinetic energy from the wind, and converts it to electricity that is compatible with a home’s electrical system.
  • A photovoltaic (PV) system uses solar cells to convert light into electricity.  The electricity generated by a multitude of these cells can be channeled into an inverter for conversion into a usable power source that is compatible with a home’s electrical system.
