Otter Tail Power Company, a subsidiary of Otter Tail Corporation (NASDAQ: OTTR), filed its 2027-2041 Integrated Resource Plan with the Minnesota Public Utilities Commission, according to a company statement.

The plan outlines proposals to add a 50-megawatt natural gas plant expected to begin service in 2031-2032 and two 50-megawatt wind projects scheduled for 2035 and 2040. The company stated these additions are intended to meet electricity demand and maintain system reliability.

The filing also includes previously approved projects under development, including the 50-megawatt Solway Solar facility expected in 2026, the 295-megawatt Abercrombie Solar project scheduled for 2028, a 75-megawatt battery storage facility, and additional wind generation capacity.

"Our responsibility is to deliver cost-effective, reliable electricity to our customers," said Todd Wahlund, Otter Tail Power president. "This plan reflects the decisions we find best meet those expectations over the long term."

The Minnesota Public Utilities Commission will review the plan through a regulatory process that includes opportunities for public and stakeholder input. Otter Tail Power expects to file a separate resource plan in North Dakota in 2027. South Dakota does not currently require an integrated resource plan.

The company develops its resource plans using forecasts for customer demand, available generation resources, and market conditions across its service territory.
