Power costs at our Sebree plant is impacted by capacity demand charges, which are determined based on available power generating capacity in MISO, from which we purchase energy. The price of such capacity is set by auction annually in the spring. Our expected capacity demand costs for power were approximately $3.1 million for the twelve months ending May 31, 2025, in addition to the market price of power used. We anticipate the capacity demand power costs resulting from the spring 2025 auction for the twelve months ending May 31, 2026 to be approximately $6.2 million.
