Central Iowa Power Cooperative (CIPCO), based in Cedar Rapids, is Iowa's largest cooperative energy provider. In operation since 1946, CIPCO generates and transmitts electricity to 13 member-owned electric cooperatives and associations, including Consumers Energy.  These cooperatives distribute the power to populations of nearly 300,000 member-owners located in 58 of Iowa's 99 counties.  The service territory stretches 300 miles diagonally across Iowa, with over 300 member substations and delivery points.

  • CIPCO invests in the development of renewable energy projects in several ways. We operate six small-scale solar arrays near communities we serve and retain the renewable energy certificates associated with each. We also contract with energy producers for the electricity output from wind, solar, hydro, and methane gas from a landfill (converted into electricity). CIPCO cannot claim these resources as renewable within our supply portfolio as we have either sold to third parties or do not receive the renewable attributes associated with the electricity produced from these renewable power sources. By selling these attributes (RECs), we not only support other organizations in meeting their renewable energy goals, we also generate revenue to help us lower our wholesale power rate to our 12 Member-owner distribution cooperatives and 15 municipalities.

  • A percentage of market purchases exist within the portfolio to meet additional supply needs not covered by existing contracts or CIPCO-produced generation. Weather volatility and unplanned operational events at power plants may also impact market purchases.
