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.
- 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.
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.
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.
Utility Incentive Programs
|Northern Indiana Public Service Company (Solar PV feed-in-tariff)||
$0.1564 and $0.17/kWh
$0.138 and $0.15/kWh
>5kW and <10 kW
>10kW and <200 kW
The list below provides some resources for each type of policy or program. Please reference and contact relevant authorities and local utilities for the most up-to-date and accurate information on state and utility policies and incentive programs.
