Indianapolis Power & Light Company (IPWLG) operates as a subsidiary of AES Corporation and provides retail electric utility services to approximately 500,000 residential, commercial, and industrial customers across a 528-square-mile service territory centered in Indianapolis, Indiana; its core offerings include electricity generation, transmission, and distribution from a diversified portfolio encompassing coal-fired plants such as Eagle Valley Generating Station (341 MW), Harding Street Station (1,196 MW), and Petersburg Generating Station (1,760 MW), alongside the Georgetown Gas Turbine Power Plant (158 MW peaking capacity), the 106 MW Hoosier Wind Farm, and advanced energy storage systems including the world's first grid-scale lithium-ion battery deployed in 2008 for frequency regulation. Founded in October 1926 through the merger of Indianapolis Light and Heat Company and Merchant's Heat and Light Company—both originating in the 1880s—and headquartered at One Monument Circle in downtown Indianapolis since 1935, the company delivers reliable power with a total nameplate capacity exceeding 3,500 MW while offering customer programs such as renewable energy options, green power subscriptions, electric vehicle charging rates, outdoor lighting services, and smart metering infrastructure. AES Indiana, its rebranded identity since February 2021, maintains operations exclusively in central Indiana, focusing on grid modernization, decarbonization toward 100% clean energy by 2050, and community investments totaling $2 million annually. Recent developments include the March 2024 acquisition of the 106 MW Hoosier Wind project in Benton County for $22.2 million in customer savings over six years, ongoing expansion of advanced metering infrastructure with Landis+Gyr since 2020 adding 350,000 smart meters and IoT-enabled networks, a 2025 partial settlement in its Indiana Utility Regulatory Commission rate case reducing proposed residential rate hikes by more than half while delaying further increases until 2030, and sustained strategic partnership with CDPQ supporting modernization and renewable transitions.
