Fort Wayne-based Indiana Michigan Power seeking approval to make emissions improvements to one of the two units at its Rockport Plant in Spencer County. The utility says the controls will reduce nitrogen oxide emissions.

The utility has filed for approval from the Indiana Utility Regulatory Commission to install the SCR emission controls on Unit 2 at Rockport. The IURC has already approved I&M's plans to install the technology on Unit 1 at the plant.

"Adding new, advanced emission control equipment at Rockport will further cut emissions from our lone coal-fueled power plant in Indiana while maintaining the low-cost, reliable supply of electricity it produces to support the local economies," said Paul Chodak, chief operating officer of I&M. "I&M constantly works to reduce our environmental impact while generating and delivering reliable, affordable power to our customers."

I&M says, if approved by the IURC, it plans to install the emission controls by the end of 2019. The Rockport plant employs more than 230 workers and each of the two units at the plant can generate up to 1,300 megawatts of electricity.

I&M has built three solar power facilities, two in Indiana and one in Michigan, in the past year. The Indiana facilities are located near Marion and Mishawaka. Chodak says another facility near New Carlisle is expected to come online before the end of the year.
