Minnesota municipal agency pursues permit for 47-MW Chaska gas project

On Oct. 14, the Minnesota Pollution Control Agency went out for comment until Nov. 14 on a draft air permit that would allow the Minnesota Municipal Power Agency to build the 47-MW Chaska Distributed Generation project, to be located near the intersection of Engler Blvd. and Audobon Rd. in Chaska, Minnesota.

The Minnesota Municipal Power Agency is proposing to build and operate a 47-MW plant composed of five Wartsila 20V34SG spark ignition (SI), 9.341-MW (12,526 hp), natural gas-fueled, 4-stroke lean burn, reciprocating internal combustion engines (RICE). There will also be a 500-kW emergency diesel black start compression ignition (CI) RICE.

Each of the five SI RICE will have a pair (in series) of emissions control devices: a selective catalytic reduction device (SCR) with urea injection for nitrogen oxides (NOx) control; and an oxidation catalyst for carbon monoxide (CO), volatile organic compounds (VOC) and hazardous air pollutants (HAPs) control.

Project contact information is: Minnesota Municipal Power Agency, 220 6th St S, Ste 1300, Minneapolis, Minnesota 55402, Anna Harmon, phone 612‐349‐6868.
