Interconnection agreements are available to Indiana customers in good standing who submit a complete Application for Interconnection to own and operate an eligible distributed generation facility such as solar photovoltaic, wind, biomass, or hydroelectric power. Eligible distributed generation facilities must be designed to operate in parallel with I&M’s system. Customers must also take service from I&M under an applicable standard service tariff.
Applications for Interconnection submitted after June 30, 2022 must meet the requirements outlined in I&M’s Excess Distributed Generation Rider (Rider EDG), while Applications for Interconnection received by I&M on or before June 30, 2022 deemed complete will be eligible for interconnection approval under I&M’s now-grandfathered Net Metering Service Rider (Rider NMS).
Plug-in electric vehicle (PEV) owners taking advantage of I&M’s Residential Service Plug-in Electric Vehicle (RS-PEV) Tariff or General Service Plug-in Electric Vehicle (GS-PEV) Tariff may not operate under Rider EDG.
Distributed Generation Facility Sizing
Under Rider EDG, your eligible distributed generation facility must be operated in parallel with I&M’s system and sized at a nameplate capacity of the lesser of 1,000 kW or a size projected to not exceed the customer’s average annual consumption of electricity in kWh on the premises on a per meter basis.
For eligible customers without historical electricity use data, I&M can review projected load information to ensure the facility sizing is intended primarily to offset all or part of the customer's own electrical load requirements on a per meter basis up to 1,000 kW.
Ownership and Location of Distributed Generation Facilities
Under Rider EDG, the customer must own and operate the eligible distributed generation facility located on the customer's premises.
