Large loads served under a dedicated energy-procurement model are served under the LPCS tariff, originally approved by the Wyoming Public Service Commission in 2016 and developed collaboratively with Microsoft and Black Hills Energy. LPCS uses a dedicated energy-procurement model — market energy purchases and power purchase agreements — so large-load growth does not raise costs for other ratepayers; participants must fund their own incremental transmission and distribution facilities and arrange their own backup generation.
Also active in Wyoming: Wyoming's Cheyenne corridor, built around this tariff, now hosts a specialized Microsoft data center using customer-owned, behind-the-meter dispatchable generation, an $800 million Meta project, and a $1.2 billion Related Digital/CoreWeave campus ramping from 88 MW to 302 MW.
