A Balanced Approach

With the ever-changing landscape of power generation—not only in our state—but nationally as well, IPL is planning for a future that includes increased diversification of generation resources and cleaner, more efficient options right here in the heart of Indianapolis to better meet the needs of its customers and to comply with current and future environmental rules.

This project, along with IPL's future plans, will significantly reduce dependence on coal, making natural gas IPL's largest source of capacity. This week marks the end of an era for IPL’s Harding Street plant.  Since 1931, when this plant first went online, it has predominantly burned coal.  After this week, coal will be completely eliminated as a fuel source at Harding Street.  In May of 2014, IPL received approval from the Indiana Utility Regulatory Commission (IURC) to convert Harding Street Units 5 and 6 from coal to natural gas.  Those units were converted at the end of 2015.  Unit 7 will follow after this week to complete the plant refueling to natural gas. 

I had the chance to sit down with Kris Larson, Harding Street Station Plant Manager, to talk shop about his role in this change, what kind of training is required to operate new equipment and the effects environmental laws have on the utility industry.

“It’s interesting to see how the development of the environmental laws affect the company and affect the public… and what we are doing here to comply.”


IPL has answered the Environmental Protection Agency’s (EPA) stringent clean-air regulations with a number of environmentally-friendly power generation and energy storage solutions.  To learn more about our efforts, visit our Power Generation  page.

IPL Generation Fast Facts:
  • Petersburg Generating Station–Located in Pike County, this generating station is primarily coal-fired and contains a production capacity of 1,723 megawatts (MW) of power. 
  • Eagle Valley Generating Station–Located in Martinsville, this generating station is primarily coal-fired and contains a production capacity of 263 MW of power. These coal units will be retired in 2016 and replaced with a combined-cycle gas turbine, which will generate about 650 MW of electricity more efficiently and with fewer environmental emissions. 
  • Georgetown Station–Located on the northwest side of Indianapolis, this station is generated via gas-fired combustion turbines and contains a production capacity of 158 MW of power. 
  • Harding Street Station–Located on the southwest side of Indianapolis, this generating station is completely fired by natural gas by spring of 2016 and contains a production capacity of 1,004 MW of power. 
  • IPL purchases 300 MW of wind power under two long-term agreements and contracts to purchase power from nearly 100 MW of solar facilities.
