The supplemental ratio of earnings to fixed charges includes Minnesota Power's obligation under a contract with
Square Butte which extends through 2026, pursuant to which Minnesota Power is entitled to approximately 71% of the
output of a 455-megawatt coal-fired generating unit (Unit). Minnesota Power is obligated to pay its pro rata share of
Square Butte's costs based on Unit output entitlement. Minnesota Power's payment obligation is suspended if Square Butte
fails to deliver any power, whether produced or purchased, for a period of one year. Square Butte's fixed costs consist
primarily of debt service. Variable operating costs include the price of coal purchased from BNI Coal under a long-term
contract. (See Note 14.)
