A major energy infrastructure project is set to move forward in Marshalltown, as Alliant Energy prepares to begin construction on the new Bobcat Energy Center later this year.
Approved in December 2025 by the Iowa Utilities Commission, the 720-megawatt facility will be built adjacent to the existing Marshalltown Generating Station, reinforcing the city’s growing role in regional power generation.
The new Bobcat Energy Center (BEC) will be located near Alliant’s current generating station, which has been operational since 2017 and produces approximately 650 megawatts of electricity.
Company officials noted that Marshalltown stood out among several potential sites due to its infrastructure, location and readiness for expansion.
“Construction of the new plant is expected to begin late in the third quarter,” said Dave Herkert.
While a final project cost has not yet been disclosed, officials indicated that estimates remain flexible as planning continues. Once completed, the facility is expected to be operational by 2029.
The project is expected to deliver significant economic benefits to the region, including job creation, increased tax revenue and long-term industrial growth opportunities.
“Unanimous siting approval reinforces our commitment to delivering reliable, cost-effective energy while strengthening the communities we serve,” said Mayuri Farlinger.
Local leaders anticipate a surge in construction employment and related economic activity during the multi-year build.
“This milestone for the BEC shows great momentum for the Marshalltown community in terms of economic development, from new construction jobs and tax revenue, to strengthening our capacity to attract new industrial and manufacturing opportunities,” said John Hall.
“Real growth begins with reliable, consistent access to energy,” Hall added.
Marshalltown Mayor Mike Ladehoff emphasized the wide range of job opportunities expected during construction.
“The BEC positions will be high-paying professional-level jobs such as skilled construction workers, electricians, heavy-equipment pipe-fitters, plumbers, truck drivers and more,” he said. “The MGS project was a boon for Marshalltown and the area. Motels, restaurants and service stations experienced significant revenue gains during a three-year construction phase. I expect the same for BEC … I also expect a number of workers will bring in trailers to reside during the project.”
Once operational, the Bobcat Energy Center will function as a flexible energy resource, capable of ramping up to full capacity in less than 15 minutes to meet peak electricity demand. Its proximity to the existing plant will allow both facilities to work in tandem, improving grid reliability and efficiency.
The project has also received strong backing from labor organizations, including local unions and trade groups, highlighting confidence in workforce availability despite broader industry concerns.
“There will be room for that … and for Marshalltown residents as well,” said Richie Schmidt, referring to job opportunities created by the project.
“We may have to work a little bit harder, but we have been able to fill every job … we have not had shortage,” he added.
With approximately 1,200 union members across multiple counties, labor leaders remain optimistic about meeting workforce demands.
In addition to construction jobs, the completed facility will require a smaller operational workforce, with about 10 full-time employees expected to manage the plant, compared to 22 at the existing station.
The Bobcat Energy Center represents a major investment in energy infrastructure and economic development for Marshalltown, combining job creation, grid reliability and long-term growth potential as construction prepares to begin later in 2026.
