• Energizing the initial segment of the project marks a significant milestone in connecting the company’s Wyoming and South Dakota electric systems.
• The strategic project is expected to stabilize long-term transmission costs for customers, expand market access to energy, and support long-term growth in Wyoming.

RAPID CITY, S.D., Jan. 15, 2025 (GLOBE NEWSWIRE) — Black Hills Corp. (NYSE: BKH) today announced that its Wyoming electric utility has successfully placed in service the initial 12-mile segment and supporting substations of its Ready Wyoming transmission expansion project near Cheyenne, Wyoming.

The approximately 260-mile transmission project will support current and growing energy needs of the company’s Wyoming customers, including data centers, while reducing dependence on third-party transmission systems. Once fully operational, Black Hills’ Wyoming electric system will be interconnected with its South Dakota electric system. This interconnection is expected to provide customers with long-term price stability while enhancing the resiliency of the electric system and expanding access to power markets and renewable energy resources.

“Ready Wyoming, the largest electric transmission project in Black Hills’ history, delivers on our commitment to serving the growing energy needs of our customers in Wyoming,” said Linn Evans, president and CEO of Black Hills Corp. “This expansion of our electric infrastructure enhances both the reliability and resiliency for our existing retail and data center customers, as well as the ability to serve new customers.”

The 260-mile project is being completed in multiple segments, and the investment will be recovered through the company’s transmission rider. The project is on schedule to be fully operational by the end of 2025. When complete, the project will add a total of six new, replacement or expanded substations and will interface with electricity markets to the east and the west.

“We remain focused on prudently managing costs for customers. This project will enable ongoing cost-effective access to energy, as we eliminate third-party transmission expenses, and support our thriving and growing Wyoming communities,” added Marne Jones, senior vice president, utilities. “I would like to thank our team and stakeholders for meeting this milestone and for their continuing work to advance this complex project, which spans five counties and approximately 300 landowners.”

The company received approval for the project from the Wyoming Public Service Commission in 2022 and commenced construction in 2023. Ready Wyoming is expected to contribute more than $100 million of economic benefit to the Wyoming economy.
