Wind power in Indiana

The following table compares the growth in wind power installed nameplate capacity in MW for Indiana and the entire United States from 2007 through 2019. As of 2017 the state of Indiana ranks 12th in installed wind capacity and number of wind turbines with 1,897 MW and 1,096 turbines, respectively. Together, these yield 4.82% of the total in-state electricity production (~4,368,000 MWh or enough to power ~453,000 homes). However, offshore wind power development is far behind onshore development in the United States generally, because onshore development is cheaper and the United States has an abundance of suitable onshore sites to develop. As of 2026, Indiana has no offshore wind farms. ==Wind generation==

Teal background indicates the largest wind generation month for the year. Green background indicates the largest wind generation month to date. Source: As this graph indicates, Indiana generally tends to have more steady wind from fall to spring months, evidenced by the fact that even in southern Indiana, wind chill is a common factor of outside conditions. October and November, for example, often see large variances in temperature, causing more days of strong gusty winds, thereby generating more wind electricity production. The same happens in March and April. However, often in the summer months, the air tends to stagnate, resulting in less wind electricity production. == Wind farms ==

The following table of wind farms and utility-scale wind power developments uses data from the AWEA, and other sources. For the larger projects constructed in phases, the table lists separate information for each phase. The name of each wind farm is the one used by the energy company when referring to it. The "wind farm" suffix is implied and hence removed for brevity. For more details and references for each wind farm, see its article. ==Single-unit turbines==

In addition to the above wind farms, single stand-alone units have also been built in multiple other locations, mostly at schools. Some of these units were placed to test the environment for future wind energy development. ==Environmental impact==

According to the USDOE, each 1000 MW of wind power capacity installed in Indiana will annually save 1,684 million gallons of water and eliminate 3.1 million tons of carbon dioxide emissions. For comparison, Indiana emitted a total of 1,883 lbs/MWh of carbon dioxide in 2015. Indiana lacked a renewable energy standard, unlike several other midwestern states: Ohio, Illinois, Michigan, Minnesota, Missouri and Iowa. Nevertheless, Indiana's wind power development had outpaced that of Ohio and Michigan. ==Government policies and initiatives==

The Indiana State government, along with the Federal Government, has put many incentives in place for the use of wind energy. The three main categories of incentives are utility, state, and federal. Utility Utility incentives target customers who have their own small wind energy systems. These incentives consist of net metering and feed-in tariff (FIT) incentives. Net metering allows the utility company to track the energy the wind system produces, and customers can then use that energy as a credit on their bills. The FIT program, only adopted by the utility company Northern Indiana Public Service Company (NIPSCO), pays their customers per kWh of energy produced by their wind turbine, as opposed to offering a credit. Currently NIPSCO mandates a rate of $0.17/kWh for systems less than or equal to 100 kW and $0.10/kWh for systems 100 kW to 2 MW. State State-level incentives consist of the Renewable Energy Property Tax Exemption and Indiana Sales Tax Incentive for Electrical Generating Equipment. The renewable energy exemption states that the assessed value of any wind system installed after December 31, 2011, is eligible for property tax exemption pending the completion of state form 18865. The sales tax incentive states that the equipment used to produce renewable electricity are eligible for a sales tax exemption. The state of Indiana also implemented a voluntary Clean Energy Portfolio Standard (CPS) in May 2011. The CPS set a goal for the state to have 10% of its electric generation come from clean energy by 2025. Federal Federal incentives include the Rural Energy for America Program (REAP), Business Energy Investment Tax Credit, and the Residential Renewable Energy Tax Credit. The REAP program provides grants to agricultural producers and rural businesses for projects that yield more energy efficiency and renewable energy. The Business Energy Tax Credit, as of September 18, 2017, is only available to large wind turbines (greater than 100 kW in capacity) and was set to expire on December 31, 2019. The credit is currently at a rate of 24% of invested expenditures with no credit cap. The Residential Renewable Energy Tax Credit is similar to the Business Investment credit except only small turbines qualify (cannot exceed 100 kW). As of September 18, 2017, the tax credit was at 30% with no max. This credit was also set to expire on December 31, 2019. ==See also==
