Solar power in Indiana has been growing in recent years due to new technological improvements and a variety of regulatory actions and financial incentives, particularly a 30% federal tax credit, available through 2016, for any size project.[1]

An estimated 18% of electricity in Indiana could be provided by rooftop solar panels.[2] In 2011, Indiana's largest solar installation was the six acre array located on the roof of the Maj. Gen. Emmett J. Bean Federal Center in Lawrence, Indiana, capable of generating a peak power of over 2 MW.[3]

Three 10 MW solar power plants are planned for Indianapolis.[4]

Government policy[edit]

The Government of Indiana has taken a variety of actions in order to encourage solar energy use within the state.

Net metering[edit]

The state has a net metering program that allows installations of up to 1 MW of on-site electrical generation to continuously roll over any excess generation to the next month. Participation is limited to 1% of utilities most recent peak summer demand.[5] Peak summer demand for the state for 2011 was 20,251 MW.[6]

Feed In Tariff[edit]

Indiana's Northern Indiana Public Service Company, NIPSCO, offers a feed-in tariff of $0.30/kWh for systems from 5 to 10 kW, and $0.26/kWh for systems from 10 kW to 2 MW.[7] Indianapolis Power & Light has a Renewable Energy Production program that pays $0.24/kWh for solar from 20 kW to 100 kW and $0.20/kWh for solar arrays of from 100 kW to 10 MW. Payments are for 15 years, participation is limited, and one third of the program, 45,900 MWh/year, will be made available through a reverse auction. No new applications will be accepted beyond March 2013.[8]

Indiana Solar Energy Working Group[edit]

The Indiana Office of Energy Development has created the Indiana Solar Energy Working Group to promote the development of solar energy, including local manufacturing.[9]
