Fuel Mix and Emissions Disclosure

August 09, 2023


Iowa adopted regulations in 2003 that require a rate-regulated electric utility to annually disclose to its customers the fuel mix of its electricity production and the associated sulfur dioxide, nitrogen oxide, and carbon dioxide emissions emissions, expressed in pounds per 1000 kilowatt-hours. This requirement excludes non-rate-regulated electric utilities physically located outside of Iowa that serve Iowa customers.
