Local Electric Cooperatives Complete Deal, Make History with Acquisition of Alliant Energy Electric Service Territory

Sioux Valley Energy with 11 other electric distribution cooperatives, wrote a new page on July 31, 2015 with the completion of the acquisition of Alliant Energy’s electric service territory in southern Minnesota. As a result, all southern Minnesota customers of Alliant Energy are now member-owners of their respective electric cooperative.

“It is a very unique situation for electric cooperatives to have the opportunity to purchase service territory from investor-owned utilities,” said Tim McCarthy, general manager and CEO of Sioux Valley Energy. “Further, it is the first time to our knowledge that several – we have 12 – electric cooperatives have banded together to acquire new service territory.”

In 2013, the 12 cooperatives formed Southern Minnesota Energy Cooperative (SMEC) as the single point of contact for the purchase of electric service territory in southern Minnesota from Alliant Energy. The more than two-year process of acquiring the territory involved receiving approvals from the Minnesota Public Utilities Commission, Iowa Utilities Board and the Federal Energy Regulatory Commission. The acquisition transfers approximately 43,000 electric accounts to local electric cooperatives.

Sioux Valley Energy will add more than 800 new members to its current membership of 23,000.  Cities added to those Sioux Valley already serves are Ash Creek, Beaver Creek, Hills, Kanaranzi, Kenneth, Magnolia and Steen.

“We are excited to share the benefits of being a member of a cooperative with these new member-owners,” McCarthy added. “Our team of dedicated employees has been serving this area with reliable, affordable electricity for more than 70 years. We look forward to meeting and building relationships with these individuals, families and business owners.

All of the cooperatives’ new member-owners were mailed a transition guide, letter and postcard with their cooperative’s contact information.  Member-owners can expect to receive welcome material with all the essential information from their electric cooperative by mail. 

“It has been a win-win opportunity from the beginning,” said McCarthy. “For our new member-owners, they will receive high-quality service at lower rates than if Alliant Energy had continued to serve as their electric utility. For our legacy member-owners, this acquisition grows and increases the efficiency of each cooperative by spreading fixed costs over more member-owners.”

McCarthy added that every participating electric cooperative has worked with exceptional diligence over the last two years to assure a smooth transition. “We are ready to welcome our new member-owners,” he said.
