At 100% efficiency, the biofuel generator has the potential to generate 5.4 Million kWh's of electricity annually. Prior to 2016, The St. Cloud Wastewater Treatment Facility purchased nearly 6 Million kWh of electricity to treat 10 Million gallons of influent flow a day.
In 2021, The St. Cloud Wastewater Treatment Facility generated over 98% of the required electricity on-site. When daily conditions are optimal (for example: no snow covering the solar panels) the facility can run at net zero - which means it is not purchasing any electricity from the grid.
With the addition of community solar garden subscriptions, St. Cloud creates or subscribes to over 100% of their annual energy demand.
