Solar PV

Important Note: Interconnection procedures in Jo-Carroll Energy's Geneseo service territory are different from the rest of our service area and have different sizing requirements. Please contact our office at 800-858-5522 for more information or email dg@jocarroll.com.

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  20 kVA please refer to the Level 1 grid interconnection application criteria.

Grid Interconnection​​ Application Criteria

Level 1- Lab-certified inverter-based interconnection equipment with an aggregate electric nameplate capacity less than or equal to 20 kVA.

Level 2- Lab-certified interconnection equipment with an aggregate electric nameplate capacity less than or equal to 2 MVA.

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.

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 Schedule

  • Level 1 (up to 20kVA) - $250.00
  • Level 2-4 (greater than 20 KVA but no more than 100 kVA) - $500.00
  • Level 2-4 (greater than 100 kVA but no more than 500 kVA) - $1,000.00
  • Level 2-4 (greater than 500 kVA but no more than 2 MVA) -  $2,000.00
  • Level 2-4 (greater than 2 MVA) - $5,000.00

For Levels 2-4, please contact our office at 800-858-5522 or email dg@jocarroll.com

Energy Value

Net Metering ( ≤ 20 kW)

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.

Important Note: Interconnection procedures in Jo-Carroll Energy's Geneseo service territory are different from the rest of our service area and have different sizing requirements.

In the Geneseo area where power is supplied by Prairie Power Inc. (PPI), members installing solar PV arrays can only take advantage of avoided cost. Net metering is no longer available for new systems in Jo-Carroll Energy’s Geneseo service area. This avoided cost rate in the area served by PPI is an annual rate. For 2023 it is $0.03841/kWh returned. If you would like to install distributed energy resources in the Geneseo service area, please contact Jo-Carroll Energy at 815-858-2207, ext. 1339 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.
