Minnesota municipal group permits 47-MW peaking project

The Minnesota Municipal Power Agency is proposing to build and operate a 47-MW plant in Shakopee, Minnesota, said a Jan. 1 public notice from the Minnesota Pollution Control Agency, which has up for comment until Feb. 1 a draft air permit for the project.

The facility will generate electricity with five Wartsila 20V34SG spark ignition (SI), natural gas-fueled, 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 control devices; a selective catalytic reduction device (SCR) with urea injection for NOx control, and a chemical oxidation (carbon monoxide catalyst) device for carbon monoxide, volatile organic compounds (VOC), and hazardous air pollutants (HAPs) control.

This is called the Shakopee Distributed Generation project, and will be located at Vierling Drive E in Shakopee in Scott County.

A listed project contact is: Anna Harmon, 220 South Sixth Street, Suite 1300, Minneapolis MN 55402. That is the address for the Minnesota Municipal Power Agency, which manages several power plants for its member cities.

Notably, Wartsila said Dec. 30 that it has agreed to supply Rochester Public Utilities (RPU) in Minnesota with a 47-MW natural gas plant that should begin operation in the spring of 2018. The order includes five Wartsila 34SG engines, Wartsila said. The quick-start attributes of the facility will also support increased use of wind and solar energy in Minnesota.
