Description of Nisource Inc
NIPSCO Electric generates, transmits, and distributes electricity to approximately 500,000 customers across 20 counties in northern Indiana. Its operations include wholesale electric and transmission transactions, as well as customized electric service agreements for data center customers. The transmission system operates at voltages ranging from 69,000 to 765,000 volts and comprises about 3,000 circuit miles, 65 transmission substations, 240 distribution substations, and approximately 312,500 poles.
NIPSCO owns and operates various generation assets, including eight renewable facilities—three of which were commissioned in 2025—two hydroelectric plants, a combined cycle gas turbine (CCGT), and two coal plants. The company also sources power through power purchase agreements (PPAs) totaling approximately 1,200 MW, with contracts expiring between 2038 and 2045. The R.M. Schahfer coal facility is under a federal emergency order to continue operation through March 2026, while the Michigan City coal facility is scheduled for retirement by the end of 2028.
NIPSCO participates in the Midcontinent Independent System Operator (MISO) transmission and wholesale energy market, with MISO dispatching its generating units. In 2025, NIPSCO's owned generation accounted for 55.4% of system load, with the remainder procured through PPAs and the market. The company operates in exclusive retail service areas, limiting retail competition, but competes nationally and internationally for data center customers. Seasonal sales fluctuations occur, with higher revenues during the cooling season. NIPSCO maintains regulatory compliance and has filed and received approval for recent rate cases covering its electric and gas operations.
