RAPID CITY, S.C., July 30, 2025 (GLOBE NEWSWIRE) -- Black Hills Corp. (NYSE:BKH) today announced financial results for the second quarter ending June 30, 2025. Operating income, net income available for common stock and earnings per share for the three and six months ended June 30, 2025, compared to the three and six months ended June 30, 2024, were:

Earnings of $0.38 per share compared to $0.33 per share for the second quarter of 2024 benefited from new rates and rider recovery, and milder weather in the prior year, which were partially offset by higher operating expenses, financing and depreciation costs.

"We delivered strong earnings and achieved key milestones for our regulatory and growth initiatives," said Linn Evans, president and CEO of Black Hills Corp. "We are maintaining our solid financial credit metrics and executing on our $1 billion capital plan for this year to serve our customers and support our long-term growth strategy. I'm pleased with the relentless focus of our team in advancing our strategy and remaining on track to achieve our 2025 earnings guidance that represents 5% year-over-year growth at the midpoint.

"We are successfully executing on our plan to deliver in the upper half of our long-term 4% to 6% growth target as we complete and advance our pipeline of key regulatory and growth initiatives. Our $350-million Ready Wyoming electric transmission project is on track for completion by year-end 2025, and during the second half of 2026 our $280-million Lange II generation project in South Dakota is planned to be in service. Meta's new data center site is under construction in Wyoming, which will contribute to our forecast of more than 10% of our EPS from data centers by 2028. Additionally, upside potential from data centers, blockchain demand and other organic growth in our service territories will drive transmission and generation investment opportunities further supporting our long-term growth trajectory," concluded Evans.

SECOND-QUARTER 2025 HIGHLIGHTS AND RECENT UPDATES

Electric Utilities

• In the first half of 2025, Wyoming electric recorded four new all-time peak loads, including an all-time peak of 379 megawatts on June 20, 2025. The peaks represent 19 consecutive years of increasing electric demand in Wyoming and an increase of 21% over the all-time peak in 2024.
  
  
• On June 30, the company established its Emergency Public Safety Power Shutoff program across all three of its electric utilities to promote customer safety and mitigate wildfire risk. In establishing the PSPS program, the company engaged with wildfire experts and key stakeholders including customers, community and local agencies, regulators and community leaders.
  
  
• During the second quarter, Wyoming Electric continued construction of its 260-mile, $350-million Ready Wyoming electric transmission expansion project. The project is on track to be completed and in service by year-end 2025. The project is expected to maintain long-term cost stability for customers, enhance system resiliency and access to power markets, support local economic growth and facilitate development of Wyoming's strong wind and solar natural resources.
  
  
• On June 10, South Dakota Electric received approval from the Wyoming Public Service Commission for a certificate of public convenience and necessity (CPCN) for the 99-megawatt, $280 million Lange II gas-fired generation project. The new facility is scheduled to begin construction in the third quarter of 2025 and to be in service during the second half of 2026. The addition of these resources will replace generation resources planned for retirement and support updated planning reserve margin requirements.
  
  
• During the second quarter, Colorado Electric continued to advance the addition of 350 megawatts of new renewable generation resources in support of its Clean Energy Plan. In 2024, the Colorado Public Utilities Commission approved the addition of a 100-megawatt utility-owned solar project, a 50-megawatt utility-owned battery storage project and a 200-megawatt solar power purchase agreement. On June 12, the company filed a request for a CPCN for the battery storage project and expects a decision by year-end. Negotiations with counterparties for the other two projects are ongoing, which will drive the final cost and timing of projects.
  
  

Gas Utilities

• On July 24, Kansas Gas received approval from the Kansas Corporation Commission of a settlement agreement for its rate review request seeking approval to recover approximately $118 million of system investments and increased operations and maintenance costs driven by inflation and operational needs to serve customers.

The settlement provides the renewal of the company's safety and integrity rider and allows for a new insurance cost tracker with deferred accounting treatment. It also includes approval for the company to file an abbreviated case during the first quarter of 2026 that includes the addition of capital placed in service through Dec. 31, 2025.
  
  
• On May 1, Nebraska Gas filed a rate review request with the Nebraska Public Service Commission seeking approval to recover approximately $453 million of system investments and increased operations and maintenance costs driven by inflation and operational needs to serve customers. The rate review requested $35 million of new annual revenue based on a capital structure of 50.5% equity and 49.5% debt and a return on equity of 10.5%. Interim rates will be effective Aug. 1, 2025 and new final rates in the first quarter of 2026.
