A US$1.2 billion major hybrid energy project combining solar generation and large-scale battery storage is moving forward in Wyoming, marking a significant expansion of renewable power infrastructure supporting data center demand in the region.
Enbridge is developing the Cowboy Project near Cheyenne, which will supply clean, dispatchable electricity to support data center operations. The first phase expands the companies’ existing partnership to approximately 1.6 GW of contracted capacity across North America.
The project integrates 365 MW of solar generation with a 200 MW / 1,600 MWh battery energy storage system (BESS), designed to enhance grid reliability and improve the flexibility of renewable energy delivery. The storage component allows excess solar energy to be captured during peak production periods and dispatched when demand on the grid increases.
At the groundbreaking, Enbridge described the project as part of its broader strategy to expand its power portfolio and deliver scalable energy solutions for large customers. Senior Vice President of Corporate Strategy and President of Power, Allen Capps, said the integration of solar and storage provides reliable energy while strengthening overall grid performance.
Delivery
Electricity from the project will be delivered through Cheyenne Light, Fuel and Power, operated by, under Wyoming’s Large Power Contract Service (LPCS) tariff. The structure is designed to serve large-load customers such as data centers while maintaining stable retail electricity pricing for other users.
The battery storage system will operate under a long-term tolling agreement, with supplying and servicing the energy storage technology. The arrangement enables flexible energy dispatch while supporting large-scale digital infrastructure requirements.
Meta has emphasized the importance of combining renewable generation with storage to ensure reliable power supply for its data center operations. Head of Clean and Renewable Energy Amanda Yang noted that the project will deliver both grid benefits and operational flexibility for high-demand computing facilities.
On the utility side, Black Hills Corporation Senior Vice President and Chief Utility Officer Marne Jones highlighted the role of Wyoming’s large-load tariff framework in enabling efficient development of large-scale energy projects while protecting existing customers.
The Cowboy Project is part of a broader Enbridge renewable energy portfolio supporting Meta, including major developments in Texas. The company expects to invest approximately US$1.2 billion in the Wyoming project, which is scheduled to enter service by the end of 2027.
As demand from data centers continues to grow, hybrid solar-plus-storage projects like Cowboy are increasingly becoming a key model for delivering firm, renewable energy at scale.
The Cowboy Project in Wyoming reflects a broader trend also seen in Texas, where large-scale battery storage is increasingly being deployed to strengthen grid reliability. In Bexar County, the 120 MW Alamo City Battery Storage project is advancing a similar model focused on peak demand management and system flexibility, highlighting how utility-scale storage is becoming a core part of both data center power strategies and regional grid infrastructure across the United States.
