Site work for a power facility in Ames, Iowa. Design plans call for site work for a power facility.

ITC (an independent transmission company) is building a new 161kV substation in the Prairie View Industrial Center on the south side of Lincoln Way adjacent to Ames' 161 kV line. ITC has requested to interconnect to Ames' existing 161 kV line. The purpose of this substation is for ITC to provide Alliant Energy with the necessary capacity to service Alliant's anticipated new customers in this vicinity and to transfer some of its existing distribution load to the transformer(s) planned as part of this substation. This CIP project is to fund a 1/3 share of this substation in order for Ames to secure capacity and transmission path rights as a joint owner in this substation. The project will also fund the professional services necessary to support this interconnection effort which will require replacement of relays at the Ames Plant 161 kV substation and design review of ITC's plans for metering, relaying, controls, and transmission line modifications necessary to complete this interconnection. Ames' reliability will be enhanced as Alliant adds an additional 161 kV line from its Fernald substation. Under the interconnection and Joint Ownership Agreements, MidAmerican Energy Company will remain as Ames' Transmission Operator. The project is included in the City's 2025-2030 Capital Improvement Program (CIP). As of December 12, 2025, information regarding design firm and general contractor selection timeline has not been released. Further details regarding construction and completion timelines have not been disclosed. *Project information has been obtained through a public capital improvement plan (CIP).
