BAY FRONT, a 67 MW Biomass power plant in Ashland County, Wisconsin. Operated by NORTHERN STATES POWER CO - MINNESOTA, commissioned 1952.

How BAY FRONT compares

With 67 MW of capacity, BAY FRONT ranks 32nd among the 141 operating power plants Bywatts maps in Wisconsin and 2nd of the 12 operating Biomass plants in the state. It accounts for about 21% of Wisconsin's operating Biomass capacity and 0.4% of all operating capacity in the state. Nationally it is the 50th-largest of the 350 operating Biomass plants in the database. Commissioned in 1952, it is older than 53% of the 141 operating Wisconsin plants with a recorded commissioning year. Its operator, NORTHERN STATES POWER CO - MINNESOTA, runs 18 operating plants in Wisconsin totaling 806 MW. It shares Ashland County with one other operating plant, WHITE RIVER.

Under the same EIA plant code, EIA-860 lists 2 generators at the site with 47 MW of nameplate capacity (this page's HIFLD capacity figure is 67 MW). Net generation was 160 GWh in 2024 (a 39% capacity factor), down 8% from 2022. Its generators came online between 1952 and 1957.

Weather peril exposure

BAY FRONT is a 67 MW biomass power plant in Ashland County, WI, operated by NORTHERN STATES POWER CO - MINNESOTA, commissioned in 1952. Ashland County carries moderate modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.8 of 5 at the 21st national percentile. Lightning is the leading peril, rated Relatively Low by FEMA at the 96th percentile.

The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a biomass plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
