Indeck wins air permit for 1,000-MW Indeck Niles project in Michigan

The Michigan Department of Environmental Quality on Jan. 4 issued an air permit for a new natural gas-fired combined-cycle plant being developed by Indeck Niles LLC.

The new natural gas combined-cycle (NGCC) plant would be located at 2200 Progressive Drive in Niles, Michigan. The site is currently a vacant railroad yard. The plant will feature state of the art turbine models with the latest technologies (“H” and “J” classes), which utilize higher firing temperatures (up to 1,620 degrees F) to achieve optimal efficiency of the units. Each combustion turbine generator (CTG) is to be connected to a HRSG, creating a single emission unit, which is referred to as a CTG/HRSG train.

The maximum design heat input capacity, on a fuel heat input basis, for each CTG will not exceed 3,421 MMBTU/hr and for each duct burner will not exceed 740 MMBTU/hr. Two combined-cycle natural gas-fired CTGs with HRSGs will be laid out in a 2×1 configuration with a steam turbine generator.

The proposed turbine generators, heat recovery steam generators, auxiliary boiler, fuel heaters, and space heaters will all burn natural gas. The proposed emergency engine and fire pump engine will burn diesel fuel.

To control NOx emissions, each train will be equipped with dry low NOx burners and selective catalytic reduction. To control carbon monoxide and volatile organic compound emissions, each train will be equipped with an oxidation catalyst. The auxiliary boiler will be equipped with low NOx burners and flue gas recirculation to control NOx emissions.

Separately, Indeck Energy Services has launched a public awareness website for the 1,000-MW Indeck Niles Energy Center. Indeck Energy said it is working through the permitting process now. Construction is projected to take 2.5 years after a fall 2017 construction start, with the facility opening in 2020.

Also in relation to this project:

  • Indeck Niles in September 2016 filed with the Federal Energy Regulatory Commission a notice of self-certification as an Exempt Wholesale Generator. It said the facility will interconnect with American Electric Power and will sell power into the PJM Interconnection market.
  • Indeck Energy Services proposes to interconnect a 994-MW natural gas-fired facility to the AEP transmission system in Michigan, said a PJM study on the project dated June 2016. The point of interconnection is located approximately one mile west of the existing Kenzie Creek 345/138 kV substation. This point will tie together the Cook–Kenzie Creek 345 kV circuit section and the Cook–East Elkhart 345 kV circuit section via a new switching station. The proposed project is under PJM queue #AA2-116.
