TerraVolt Holdings, Inc., an infrastructure developer specializing in powered land solutions for data centers, has executed option agreements to purchase 1,077 acres of land outside the town of Declo in Cassia County, Idaho, on which it intends to develop a behind-the-meter digital infrastructure campus.
The company said in a press release that the property was zoned for multiple use and was situated near long-haul fiber routes and the Williams Northwest Pipeline. The campus will have an initial 240 MW of dedicated on-site power generation, backed by TerraVolt’s previously announced firm natural gas supply agreement of 55,000 MMBtu per day.
“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 Joel Stone, TerraVolt Holding Chairman and Chief Executive Officer. “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.”
With on-site, islanded power generation, the proposed campus will avoid utility interconnection delays. In states like Texas, data center developments that require grid interconnection face lengthy delays, with w.media reporting in September that the Electric Reliability Council of Texas was tracking 438 GW of large load requests, 89 percent of which were for data centers.
TerraVolt said the behind-the-meter deployment will reduce the time-to-power schedule for hyperscale and neocloud deployments and protect existing ratepayers from grid strain or rate increases.
TerraVolt plans to sell shovel-ready building sites to data center operators, providing power, fiber, potable and fire-protection water, wastewater treatment, and other site services under long-term infrastructure services agreements.TerraVolt also intends to require low water usage for any data center developments on the property, making it a condition of sale for each site.
“We look forward to working closely with Cassia County officials and the local community to deliver responsible, long-term industrial tax base growth without impacting local power rates or the agricultural water the region depends on. That is why every building on this campus will be required to use cooling technologies with low water usage,” said Stone.
According to Data Center Map, there are currently 25 data centers under development or operational in Idaho. The state is also home to Meta’s Kuna Data Center, a more than US$ 1.2 billion investment, which became operational on September 3, 2026.
