Building the Marshalltown Generating Station

The Marshalltown Generating Station (MGS) project will make the state’s air cleaner for decades while creating good-paying jobs in Iowa today. We are proud that this facility will provide reliable, cleaner and cost-competitive energy to current and future generations of Iowans in a responsible way.

Work is on schedule and on budget as we work to complete the MGS in Marshalltown, Iowa. The 650-megawatt, combined-cycle, natural gas-fired facility is expected to power more than 500,000 homes. It is creating long-term environmental benefits and economic opportunities for Iowa.

Combined with retiring older coal-fired units that are no longer cost-effective to operate, the natural gas-fired MGS will improve air quality. Natural gas-fired generation has the ability to ramp up and ramp down quickly. This provides flexibility to better integrate renewable energy into the electric supply mix.

MGS is expected to begin operations by the second quarter of 2017.
