The Kansas Department of Health and Environment (KDHE) is soliciting comments until Sept. 2 on a proposed air quality construction permit for Midwest Energy on a 28-MW, gas-fired power project at an existing plant site.
The company wants to install three new spark ignition Wartsila (model 20V34SG) four stroke lean burn (4SLB) reciprocating internal combustion engine (RICE) units using pipeline quality natural gas and auxiliary equipment at the existing Goodman Energy Center. Each engine will be nominally rated at nearly 9.4 MW for a combined power output of approximately 28 MW. The company is asking for no limit on operational hours for these units per year.
The facility will also include a one million British thermal units (MMBtu) per hour gas heater, a 100 horsepower (hp) emergency fire pump, a 250 kW emergency diesel generator, a 200 gallon fuel oil storage tank, and a 20 gallon fuel oil storage tank. The facility is located in Ellis County, Kansas, approximately 4 miles northwest of Hays.
The existing plant, built late last decade, has nine RICE engines of 8.44-MW apiece. Midwest Energy is the largest electric cooperative in Kansas.
