An arrow graphic shows that Colorado’s voluntary renewable energy goals increases from 6% in 2013, to 10% in 2025.

Carve-out: None
Tracking system: PJM-Generation Attribute Tracking System (PJM-GATS)

Indiana's Clean Energy Portfolio Standard sets a voluntary goal for not just renewables but also conventional resources such as nuclear, coal, and natural gas. Up to 30% of the goal may be met with clean coal, and 50% of the goal should be met by in-state resources.

Indiana allows net metering for up to 1 MW of capacity, enabling midmarket solar customers to receive credit for excess generation. It offers an expedited interconnection process for systems <2 MW.

Latest Updates

  • Indiana passed a law in May 2017 to lower the credit that customers get for excess generation from the retail rate to an avoided cost rate for projects installed after June 30, 2022.
  • Existing solar customers and any additional projects installed before 2018 will continue to receive retail rate compensation for 30 years. Projects installed between 2018 and 2022 will receive retail rate credit until July 1, 2032.

Net Metering

The Indiana Utility Regulatory Commission (IURC) requires the state's IOUs to offer net metering to all electric customers. The compensation rate will change for projects installed after the end of 2017.

System size limit: 1 MW

Aggregate cap: Aggregate capacity limits at 1% of utility's most recent peak summer load

Credit: Net excess generation is credited for 30 years at the retail rate for existing projects and qualifying projects installed before January 1, 2018; projects installed between 2018 and 2022 will receive retail rate credit until July 1, 2032; projects installed after June 30, 2022 will receive credit for excess generation at an avoided cost rate.

RECs: Not addressed

Meter aggregation: Not addressed


IURC approved rules governing the interconnection of distributed generation in 2005, requiring the state's IOUs to provide three levels of interconnection to customer-generators.

Eligible Systems Type of Interconnection
Inverter-based systems ≤10 kW Level 1
>10kW and ≤2 MW Level 2
All other systems Level 3

System size limit: Not specified

Liability insurance: Not required, "only reasonable amounts of insurance against risks for which there is a likelihood of occurrence."

External disconnect switch: Not required

Third Party Ownership

The status of third party solar power purchase agreements is unknown in Indiana.

Community Solar

Indiana currently does not have statewide community solar policies or programs. Individual utilities offer community solar programs.

State Incentive Programs

Indiana exempts solar PV modules, racking, and inverter from state sales and use taxes. The entire solar generating system is exempt from property taxation.
