Northern Indiana Public Service Copany (NIPSCO) announced plans to shut down four of its coal generation units in the near future.
Specifically, NIPSO plans to close Bailly Generating Station and its two coal-fired units as soon as mid-2018, and two coal-fired units at R.M. Schahfer Generating Station by the end of 2023.
The company cited an aging fleet, low prices for natural gas and new environmental regulations that would require significant investments as the main factors behind the move.
NIPSCO will rely on existing capacity to replace the lost generation, and plans to seek out combined-cycle gas turbine generation for permanent replacement. However, the company may need to purchase power during the transition.
The utility now receives 72 percent of its power from coal, down from 90 percent in 2010.
NIPSCO’s closure announcement comes as the utility submitted its Integrated Resource Plan covering the next 20 years of operation to the Indiana Utility Regulatory Commission.
