Black Hills Energy has completed its 260-mile “Ready Wyoming” transmission line expansion, a $350 million investment connecting Wyoming and South Dakota’s electric systems. The project, which took 15 years to plan and two years to construct, involved building three 230 KV lines, two 115 KV lines, and multiple substations. It aims to improve energy delivery, support Wyoming’s diverse energy resources, and is expected to generate significant economic value and tax revenue for the state.
