8-K: Otter Tail Power Receives Approval for Integrated Resource Plan, Commits to Renewable Energy Expansion

The Minnesota Public Utilities Commission approved Otter Tail Power's 2022-2036 Integrated Resource Plan, mandating significant investments in renewable energy and changes to coal-fired plant operations.

Summary

• The Minnesota Public Utilities Commission (MPUC) has approved Otter Tail Power Company's Integrated Resource Plan for 2022-2036.
• The plan includes the addition of 200 to 300 megawatts of solar generation by November 1, 2027, or as soon as practicable.
• It also mandates 150 to 200 megawatts of wind generation by December 31, 2029, or as soon as practicable.
• Additionally, 20 to 75 megawatts of battery storage is required by December 31, 2029, or as soon as practicable.
• The plan approves the addition of on-site liquified natural gas storage at the Astoria Station by 2027, pending North Dakota regulatory approval.
• The MPUC directed Otter Tail Power to designate the Minnesota share of the Coyote Station coal-fired plant as an Available Maximum Energy (AME) resource from June 1, 2026, to December 2031.
• If the AME designation is not feasible, Minnesota customers will not pay for or depend on Coyote Station capacity or energy after 2028.
• Otter Tail Power must cease serving Minnesota customers with capacity or energy from Coyote Station by December 31, 2031.
• The next Integrated Resource Plan filing is due in May 2026, which will include an analysis of the continued operation of the Big Stone Plant with AME.

Industry Context

This announcement reflects a broader industry trend towards renewable energy adoption and the phasing out of coal-fired power plants. Many utilities are facing similar regulatory pressures to transition to cleaner energy sources.

Comparison to Industry Standards

• The move to add 200-300 MW of solar and 150-200 MW of wind is in line with other utilities in the Midwest region, such as Xcel Energy, which have also committed to significant renewable energy additions.
• The timeline for phasing out coal from the Coyote Station by 2031 is similar to other utilities' plans to retire coal plants, although some are moving faster.
• The addition of battery storage is a growing trend, with companies like NextEra Energy also investing heavily in this technology to support grid reliability.
• The specific targets and timelines are subject to local regulatory requirements, making direct comparisons challenging, but the overall direction is consistent with industry trends.

Stakeholder Impact

• Shareholders will be impacted by the capital expenditures required for the renewable energy transition.
• Employees will be affected by the changes in power generation operations.
• Customers will benefit from the transition to cleaner energy sources.
• Suppliers will be impacted by the increased demand for renewable energy equipment and services.
• Creditors will be impacted by the financing of the new projects.

Next Steps

• Otter Tail Power will procure the specified generation resources.
• The company will add on-site liquified natural gas storage at the Astoria Station.
• Otter Tail Power will designate the Minnesota share of the Coyote Station coal-fired plant as an AME resource.
• The company will commence activities to no longer serve Minnesota customers with capacity or energy from Coyote Station.
• Otter Tail Power will file its next Integrated Resource Plan in May 2026.
