Mandatory Utility Green Power Option

August 27, 2021


All electric utilities operating in Iowa, including those not rate-regulated by the Iowa Utilities Board (IUB), are required to offer green power options to their customers. These programs allow customers to make voluntary contributions to support the development of renewable energy sources in Iowa. Utilities must file their program plans and tariff schedules with the IUB; however, the filings for non-rate-regulated utilities are intended to be for informational purposes only.
