Black Hills Corp Receives Wyoming PSC Approval for 99 MW Lange II Power Project in Rapid City

Black Hills Corporation's South Dakota electric utility subsidiary has received approval from the Wyoming Public Service Commission for the Lange II Project, a 99 MW dispatchable generation facility in Rapid City, South Dakota. This $280 million project addresses capacity deficits caused by the retirement of aging power units and enhances planning reserve margins to ensure reliable electricity supply for customers in South Dakota and eastern Wyoming. The facility will feature six dual-fuel reciprocating internal combustion engines capable of running on both natural gas and diesel, offering operational flexibility and cost efficiency. Construction is scheduled to begin in the third quarter of 2025, with operations expected to commence in the second half of 2026. The project is identified as the least-cost resource for meeting future energy demands and reflects Black Hills Corp.'s commitment to maintaining system reliability and competitive pricing for its 1.35 million customers across eight states. Despite the significant capital investment, the company continues to maintain strong financial health and a long-standing record of dividend increases.
