Xcel Energy has unveiled a visionary proposal to enhance nearly 100 miles of transmission line in the states of Minnesota and eastern South Dakota.

The strategic upgrade is poised to usher in a new era of delivering affordable renewable energy to electricity consumers across the Upper Midwest, yielding multimillion-dollar savings annually.

This week marks a significant milestone as the company formally submitted a Certificate of Need application to the Minnesota Public Utilities Commission.

The objective is to introduce a second circuit into two segments of the pre-existing Brookings County-Hampton transmission line. The innovative second circuit will traverse the distances between Brookings, South Dakota and Marshall, Minnesota, as well as Scott and Dakota counties in Minnesota. The responsibility for permitting and construction efforts rests with Xcel Energy.

Chris Clark, the President of Xcel Energy-Minnesota, North Dakota, and South Dakota, stated that this strategic endeavour leverages existing infrastructure to mitigate congestion within the transmission system. By doing so, it minimises the impact on landowners in the vicinity.

The project, he highlighted, will not only channel renewable wind energy to countless households and enterprises at an economical cost but will also further the cause of reducing carbon emissions. This endeavour underscores the company's unwavering commitment to fulfilling energy demands dependably and cost-effectively.

The upcoming transmission project holds the promise of expanding capacity, thereby alleviating grid congestion. The intention is to facilitate the smooth flow of budget-friendly wind power from regions such as southwest Minnesota and eastern South Dakota to consumers throughout the broader area.

Wind energy, distinguished by its absence of fuel expenses, contributes to a diverse energy mix, thereby acting as a safeguard against fluctuating fuel costs and ultimately benefiting consumers financially. This project seamlessly aligns with Xcel Energy's aspiration to achieve 100% carbon-free electricity in Minnesota by 2040, in tandem with the state's progressive clean energy standards.

An intriguing facet of the proposed endeavour is that the majority of it will build upon the existing transmission line route, which first became operational as part of the CapX2020 initiative in 2015.

This joint effort involved multiple utilities, and a foresight-driven decision was made by the Public Utilities Commission and CapX2020 companies to anticipate future transmission needs.

Consequently, a segment of the line was constructed with two circuits, while the western and eastern segments were designed with "double circuit capable" capabilities. This forward-looking approach ensured that energy needs were met at the time while also accommodating future energy demands.

The new second circuit is slated to be integrated into the current transmission structures and will span approximately 60 miles, connecting the Brookings County substation near White, South Dakota, to the Lyon County substation near Marshall, Minnesota. An additional 39-mile section will extend between the Helena substation in Scott County, Minnesota and the Hampton substation in Dakota County, Minnesota.

As part of the review process, the Public Utilities Commission will evaluate Xcel Energy's proposal, a meticulous undertaking that typically extends up to a year. During this phase, input from consumers, landowners, and other key stakeholders will be actively sought. Pending state approval, the company anticipates commencing the installation of the new circuit in 2024, with the project's completion targeted for 2025.

The potential of the project goes beyond its immediate impact, as it is anticipated to yield widespread benefits in terms of congestion relief. Investment participation is expected from Central Minnesota Municipal Power Agency, Great River Energy, Missouri River Energy Services, and Otter Tail Power Company.

The Brookings Second Circuit endeavour stands as a prime example of proactive planning by Xcel Energy and fellow Minnesota utilities to meet future energy requirements in the Upper Midwest. With the surge in wind energy production in the region, the existing transmission grid has encountered constraints in effectively delivering the generated energy to consumers.

This phenomenon, analogous to a traffic jam on a highway, underscores the urgency of enhancing transmission capacity. By doing so, a gateway will be opened for the abundant reserves of economical renewable energy to seamlessly reach a broader consumer base.

Notably, Xcel Energy's proposed Minnesota Energy Connection, an independent initiative, seeks to bridge wind resources in southwest Minnesota with the infrastructure at the Sherco plant in Becker. Furthermore, the company is poised to embark on an ambitious $1 billion transmission initiative greenlit by the Midcontinent Independent System Operator (MISO).
