Steam from the boiler is piped into the #1 Turbine Generator which generates about 1.9 MegaWatt hours(MWh) of electricity each hour. After the #1 Turbine Generator, the steam passes into the District Energy System (DES) for heating or cooling.
When steam demand in the DES is low, the steam passes into the #2 Turbine Generator, which generates up to 2.1 MW hours of electricity for each hour it operates. The #3 Turbine Generator is capable of condensing all of the inlet steam and generating up to 5.5 MWh, or extracting a portion of the inlet steam to supplement the district heating and cooling system resulting in a maximum of 3.0 MWh of electricity each hour.
Excess electricity, not needed by the nearby government buildings, is sold at wholesale cost to the local power grid and provide green energy for the Southern Minnesota Municipal Power Agency (SMMPA) and Rochester Public Utilities (RPU). Buildings on the DES include the Olmsted Medical Center Hospital, the Rochester Community and Technical College (both campuses), the Federal Medical Center, the City/County Government Center, Mayo Civic Center, the Human Services Campus. Green energy opportunities also exist for businesses who wish to locate in the newly created energy park just east of the OWEF.
