ST. CLOUD – In St. Cloud, though, a pair of powerful solar arrays and a state-of-the-art biodigester that turns sewage into electricity, heat and fertilizer sometimes generate more power than the plant can use. That happened for the first time on April 12 of last year. Since then, it’s happened on 30 additional days, most recently on June 5.
