Energy Vault’s acquisition of the 175 MW / 350 MWh McMurtre BESS near Dallas adds another storage asset in ERCOT’s North region and pushes forward its broader 1,500 MW battery deployment plan. The deal also fits the company’s positioning around a Texas market shaped by strong price dynamics, ongoing grid investment, and rapidly expanding data center demand near Dallas.
That makes the story more geographic than transactional. The Dallas area is not just a battery story or a data center story on its own. It is a place where both are starting to stack together. McMurtre joins Energy Vault’s Texas buildout alongside SOSA Energy Center, a 150 MW / 300 MWh project under construction, and Cross Trails, a 57 MW project that reached commercial operation in May 2025.
Texas is also the clear center of gravity for the next U.S. storage wave. Developers plan to add 24 GW of utility-scale battery capacity in 2026, and Texas alone accounts for 12.9 GW, or about 53% of the national total. Three of the four large projects highlighted as major capacity drivers are in Texas, reinforcing how central ERCOT has become to storage growth.
Why it matters
- McMurtre is part of a broader Energy Vault push to deepen its Texas and ERCOT storage footprint.
-
The Dallas area matters because storage growth is lining up with expanding data center demand.
-
Texas is the leading U.S. battery growth market for 2026, far ahead of other states.
-
The broader ERCOT buildout is no longer about one project, but about a growing cluster of storage assets across a high-growth power market.
