TerraVolt Buys 1,077 Idaho Acres for 240MW Gas-Fired Data Center Campus

TerraVolt has acquired 1,077 acres in Cassia County, Idaho, to develop a master-planned data center campus supported by an initial 240MW of on-site, gas-fired behind-the-meter generation.

The US-based land firm said the parcel is already zoned for multiple uses and sits close to the Williams Northwest natural gas pipeline. TerraVolt has signed an agreement for 55,000 MMBtu per day of firm gas supply from the pipeline to support the campus.

Why go off-grid?

The company designed the data center's off-grid architecture to avoid interconnection delays and shorten time to power. The approach also insulates local residential and commercial ratepayers from grid strain or rate increases, according to TerraVolt.

CEO Joel Stone framed the deal around the industry's most persistent constraint. "These option agreements secure site control, allowing our team to advance land use plans, environmental due diligence, power plant, electrical distribution, and water treatment system designs, and county and state permitting," said Stone, chairman and CEO of TerraVolt Holdings.

"By pairing a strategic, expansive land parcel directly with firm gas supply and pipeline access, we are addressing the single largest bottleneck in the digital economy: the multi-year wait for large-load grid interconnections," Stone said.

In short: the company is selling speed to power, not just land.

What happens after development?

Once the site is built out, TerraVolt plans to sell the "shovel-ready" parcels to data center operators. Under a long-term infrastructure services agreement, TerraVolt would then supply those operators with:

• Power from the on-site gas plant
• Fiber connectivity
• Potable and fire-protection water
• Wastewater treatment
• Other site services

How does water factor in?

TerraVolt said water stewardship will play a central role in the campus design. The company intends to deploy low-water-use cooling technologies, specifically closed-loop cooling, for any data center built on the property.

The commitment matters in southern Idaho, where agricultural water demand shapes local politics around large industrial projects.

Who is behind TerraVolt?

CalEthos, a sustainable data center developer based in Tustin, California, launched TerraVolt in July 2024 as an Infrastructure-as-a-Service platform. The unit provides turnkey solutions to hyperscalers, colocation providers, and data center developers seeking a faster route to market.

TerraVolt originally positioned itself as a geothermal energy producer. The company has since pivoted to natural gas solutions — a shift that mirrors the broader industry move toward gas-fired generation as grid interconnection queues stretch from years toward a decade in key markets.

The Cassia County project now moves into land use planning, environmental due diligence, and county and state permitting, with gas supply and site control already secured.
