Indeck Niles 1.1 GW energy centre comes online

12 July 2022

On July 1 Indeck Energy Services along with its Korean partners KOSPO and DL Energy, officially notified the start of commercial operations of the Indeck Niles Energy Center to local regional transmission operator PJM Interconnection.

Indeck Niles is a 1.1 GW natural gas fired power plant based on two GE 7HA.02 gas turbines. It is located in the city of Niles, Michigan.

For the project, GE delivered H-Class combined cycle plant equipment and is contracted to provide parts, repairs and maintenance services for 25 years, while Kiewit provided engineering procurement and construction capabilities. Indeck developed the plant to fill the need for generating resources created by the decommissioning of older and/or less efficient coal-fired and nuclear plants in the region.

Indeck will operate the plant, located on a 373 acre site on the northeast side of the city. Because of environmental contamination, the land has largely been vacant since it was last used by the rail industry decades ago. But Indeck and its partners – Korea Southern Power Co and Daelim Energy Co – paid $59 million to clean up and contain pollutants on the site. 

The plant was built by Kiewit. All the major equipment was supplied by GE: the two GE 7HA.02 gas turbines, and two H65 generators, an STF-D600 steam turbine powering a H84 generator, and two heat recovery steam generators which are triple pressure reheat drum, along with a Mark VIe distributed control system software solution and services to support the availability and reliability of the plant. Auxiliary equipment includes dry low-NOx burners integrated with selective catalytic reduction technology for controlling the NOx emissions.

In 2020, natural gas generated the largest proportion of Michigan’s electricity for the first time, overtaking coal, which fell to third after nuclear power. Natural gas accounted for 33% of the state’s net generation, while coal’s share declined to 27%. Renewables provided about 11% of Michigan's electricity net generation in 2020, and wind energy accounted for three-fifths of that power.
