Gundersen Lutheran and City Brewery will flip the switch on a combined heat and power project that has been months in the making. As part of the unique partnership, Gundersen Lutheran installed an engine at City Brewery that will send energy to the local power grid. The engine uses methane gas discharged from City Brewery’s waste treatment process and turns it into electricity. The organizations will turn on the engine at a ceremony being held behind City Brewery corner of Front (South 2nd) St. and Market St., on Oct. 7 at 2 pm.

The combined heat and power project is projected to generate three million kilowatt (kW) hours per year, which would offset about 8 percent of the electricity used on Gundersen Lutheran’s La Crosse and Onalaska campuses.
