Galaxy Digital has secured more than 800MW in new grid capacity for its Texas data center campus.

The company this week announced that it has completed a Large Load Interconnection Study (LLIS) and received approval from the Electric Reliability Council of Texas (ERCOT) for an additional 830MW of computing capacity at its Helios data center campus in West Texas.

Galaxy has also executed a service agreement with AEP Texas Inc. for this additional capacity. Galaxy's transmission interconnection provider will be Wind Energy Transmission Texas.

The approval brings Galaxy's total approved and utility-contracted power capacity at Helios to more than 1.6GW, effectively doubling the campus’ available power.

The approval is a “watershed moment for Galaxy,” according to Mike Novogratz, founder and CEO of Galaxy.

"The demand for high-density, AI-ready data center capacity in Texas is unprecedented," he said, "With over 1.6GW of power capacity now approved, we are exceptionally well-positioned to grow our program and provide the reliable power infrastructure that the world's leading AI companies require."

After breaking ground in July 2021, the 160-acre Helios campus started operations in May 2022. Galaxy acquired the data center, located in Dickens County, from Argo Blockchain in late 2022 for approximately $65 million. As part of the deal, the two companies signed a two-year hosting deal.

Last year, CoreWeave committed to leasing what was at the time the full 800MW of approved capacity at the Helios campus, which will generate an average annual revenue of more than $1 billion over the 15-year term of the agreement.

Construction is underway to support the first phase of Helios under Galaxy's long-term lease agreement with CoreWeave. Initial power is set to become available in early 2026.

With CoreWeave set to take over the Helios campus, Galaxy Digital is moving its mining operations elsewhere, having signed a 48MW contract at Soluna's Project Kati data center in Texas.

Galaxy says that the campus has the potential to eventually support up to 3.5GW of power.

Galaxy noted it was evaluating additional power and land opportunities in Texas and beyond.
