Sources of Power

Pella Cooperative Electric is a distribution cooperative. The electricity we distribute comes from CIPCO (Central Iowa Power Cooperative), a generation and transmission cooperative. Approximately 60% of the electricity is generated from carbon and emissions-free resources minimizing the impact on the natural environment.

Coal (32.0%)

Coal is a primary source of power because it ensures a reliable electric supply and is less expensive than other technologies. CIPCO has partnered with other investor owned utilities in Iowa in co-ownership agreements in order to supply the power that is delivered to your homes. 

Nuclear (33.2%)

One third of your electricity is generated at the NextEra Energy Duane Arnold nuclear facility in eastern Iowa. Like coal, this facility is capable of producing baseload power to meet consumer demand. Nuclear is the only source of electricity that can produce a large amount of baseload power in a carbon-free environment. As our nation continues to address the climate change challenge, nuclear will surely be a necessary portion of our power portfolio.

Wind/Hydro/Solar/Landfill Gas (34.6%)

A growing percentage of your electricity is generated with renewable sources. CIPCO currently obtains hydroelectric power through the Western Area Power Administration and wind energy through partnerships with the Hancock County, Story County, Rippey Wind, Hawkeye Wind, Pioneer Grove and Elk Wind Energy Centers. CIPCO's purchase power agreement with Linn County Solid Waste Agency is for the entire output from this landfill gas-to-energy system. Electricity is produced when the system captures methane eliminating its release into the environment. The methane is used to produce electricity.  A utility scale solar project located on six member sites; Osceola, Pella, Marshalltown, Urbana, Wilton and Corning, is a photovoltaic system of 6.4 MW generation capacity owned and operated by CIPCO. All sites completed construction and began production in 2016-2017. Though the kilowatt hours produced from renewable sources can be more expensive than those generated from baseload technologies, CIPCO will continue to utilize these resources as part of the balance between reliability, affordability, and environmental responsibility.

Natural Gas & Oil (0.2%) 

Because of volatile fuel prices, natural gas and oil peaking plants are used only at times when demand for electricity is very high.


When demand for electricity is greater than what can be produced by CIPCO's generation fleet, electricity must be purchased on the open market. This is the most expensive power. If more generation sources are not brought online as consumer demand grows, CIPCO will be forced to purchase more energy on the open market which could increase the cost of your electric service.

Coal provides baseload power (power that is available 24/7 to meet consumer demand for electricity).


All or some of the renewable energy credits associated with the generation may have been sold or may be sold in the future to other parties.
