Alliant Energy’s Lansing Battery Energy Storage System enters more visible construction phase as it moves toward becoming operational in July of 2027
Alliant Energy Battery Energy Storage System at Lansing ... Aerial photo shows the overall area that once housed Alliant Energy’s coal-fired Lansing Generating Station before it was retired in late 2022 and dismantled in 2023, and now is being transitioned by Alliant Energy into a Battery Energy Storage System (BESS).

Construction of Alliant Energy’s battery energy storage system at the site of the former Lansing Generating Station south of the little river town is progressing beyond the initial earthwork phase that has been so prominent for most of this year, moving into a stage where the physical components of the facility will increasingly become more visible to residents.
In a recent project update, Alliant Energy Project Manager Keri Sweeting shared that crews have commenced the installation of conduit to help facilitate energy transmission and are preparing the concrete foundations required to support the battery units. “At Lansing, we have initiated the installation of conduit and will soon begin pouring concrete to support the batteries,” Sweeting stated.
Different sections of the site are advancing at varying rates, with some areas already experiencing concrete pad installation while other areas are still undergoing site preparation. Battery deliveries are anticipated to begin in September and will occur incrementally rather than in a single shipment, with several units potentially arriving over a period of days before additional groups are delivered at a later time.
Sweeting emphasized the significance of the Lansing battery energy storage system site in relation to Alliant Energy’s portfolio, noting, “This is the largest site that Alliant has constructed to date.”
The activities observed by residents thus far have primarily involved trucks transporting fill material to elevate sections of the site above the 500-year floodplain in the area where the form coal-powered Lansing Generating Station once stood. “We have had a considerable number of trucks on the road delivering materials to the site to elevate it above the 500-year floodplain,” Sweeting remarked, adding that this work is nearing completion in several final areas. As the project advances, it is expected that residents will increasingly observe identifiable elements of the finished facility, including a new Alliant substation, battery units, and transformers.
