Akin Energy nears permit for up-to-140-MW gas-fired project in Illinois

The Illinois Environmental Protection Agency is taking public comment until Dec. 20 on a draft air permit that would allow Akin Energy LLC to build a new, gas-fired power plant.

Akin Energy applied on Feb. 6 for a construction permit for a power generating facility to be located near Macedonia in Hamilton County. The exact location is on County Road 850 N and Highway 7 near Macedonia. The facility would use reciprocating engines to generate electricity. Natural gas would be the main fuel for the facility. The proposed facility is referred to by Akin Energy as the Hamilton County Facility.

The principal emission units at the proposed facility would be 14 natural gas-fired reciprocating internal combustion engines that will power generators to produce electricity. The nominal electrical output of the facility would be either 130 MW or 140 MW, depending on the model of engine that is selected. The proposed natural gas engines will be modern, spark ignition, turbocharged, lean-burn engines. The engines will operate intermittently to follow load requirements.

These engines will be equipped with selective catalytic reduction to reduce emissions of nitrogen oxides, as well as an oxidation catalyst, to reduce emissions of carbon monoxide. The engines will be housed in a building and each engine will vent through its own stack.

The facility will also have two “low-load” engine diesel generators. These low-load units will provide electricity when the demand is below the level at which the main engines can be operated. Two natural gas fuel heaters, an emergency diesel generator engine, and an emergency diesel fire water pump engine will be used to support the facility.
