Solar PV
Solar energy systems, also known as photovoltaic (PV) systems, use a visible renewable resource - the sun. Solar systems are most effective when they are part of an energy efficient home or business. Purchasing and installing a solar system can be a significant investment for a consumer. We recommend you carefully research the potential investment so you make the right decision. If you are interconnecting a PV system to your home or business and it is less than 10-kVA please refer to the Level 1 grid interconnection application criteria below (click "Level 1").
Grid Interconnection Application Criteria
Level 1- Lab-certified inverter-based interconnection equipment with an aggregate electric nameplate capacity less than or equal to 10-kVA. (Application fee is $50.)
Level 2- Lab-certified interconnection equipment with an aggregate electric nameplate capacity less than or equal to 2 MVA. (Application fee is $100 plus $1.00 per kVA.)
Level 3- Distributed generation facility does not export power. Nameplate capacity rating is less than or equal to 40 kVA if connecting to area network or less than or equal to 10 MVA if connecting to a radial distribution feeder. (Application fee amount is $500 plus $2.00 per kVA.)
Level 4 - Nameplate capacity rating is less than or equal to 10 MVA and the distributed generation facility does not qualify for a Level 1, Level 2 or Level 3 review, or the distributed generation facility has been reviewed but not approved under a Level 1, Level 2 or Level 3 review. (Application fee amount is $1,000 plus $2.00 per kVA, to be applied toward any subsequent studies related to this application.) This application process will be used if levels 1-3 do not apply.

Energy Value
Monthly kWh credit carried over month to month with any remaining balance reset at the end of the annual period. Any credits received by the member will be carried over to subsequent billing periods. Unused credits will expire either at the end of the annual period ending in April of each year or, at the time in which the member terminates service from the cooperative. Members remain responsible for all taxes, fees, and delivery charges that would otherwise be applicable to the gross amount of electricity supplied to the member.
In Henry County (Geneseo area) where PPI is our power provider, the cooperative will net meter up to 10kW(DC). If you would like to install distributed energy resources in excess of this, please contact Jo-Carroll Energy at 800-858-5522 or email dg@jocarroll.com
Avoided Cost and Power Purchase Agreements, PPA ( > 20 kW)
If the member is a net seller of electricity, the Cooperative shall compensate the member for any excess kilowatt-hour credits at the Cooperatives avoided energy cost of electricity supply over the monthly period or as otherwise specified by the terms of a power-purchase agreement negotiated between the member and Cooperative or Cooperative’s electricity supplier. For purposes of calculating the member's electricity bill, any resulting credits may be used to offset other charges assessed by the electricity supplier.
