Community leaders tour ITC Midwest’s Marshalltown Substation, discuss future energy needs across area

Local leaders, including elected officials, business executives, and representatives from Alliant Energy and the Marshalltown Area Chamber of Commerce, toured ITC Midwest's Marshalltown Substation. The tour, led by Josh Carlson of ITC Midwest, showcased the facility's capacity to power up to 200,000 homes and explained the role of the Midcontinent Independent System Operator (MISO) in overseeing transmission lines. The conversation frequently shifted to the topic of data centers, with ITC and Alliant representatives emphasizing the increased need for a reliable electrical grid and sufficient power generation as new data centers are built across Iowa. ITC Midwest Area Manager Jamie Toledo clarified that data centers serve critical functions beyond social media, supporting financial, health, and homeland security data. Alliant's Amanda Accola noted that future data center projects would likely be sited in areas with readily available power. Marshalltown Mayor Mike Ladehoff inquired about the city's growth potential given current and planned energy infrastructure, including the new Twinkle Substation and the 720-megawatt Bobcat Energy Center. Officials discussed the city's 95-acre certified industrial site as a major asset for attracting heavy energy users, which include not only data centers but also equipment manufacturers and food processing plants. ITC Midwest's Aaron Curtis addressed misconceptions about data centers, particularly regarding water usage, arguing they are less impactful than some common industries and can be valuable community partners. City Administrator Carol Webb and other leaders expressed appreciation for the tour and the insights gained into critical infrastructure. Morgan Hawk of ITC Midwest underscored the importance of proactive engagement and education to build transparency and trust around the essential infrastructure that supports regional reliability, safety, and economic growth.
