Joule Energy & Data Center Campus
A developer campus by Joule Capital Partners in Holden (Millard County), UT, on the West: Mountain/Northwest grid. Status: under construction.
Grid and gas impact
At full buildout this campus is announced at 4,000 MW. After phasing to 2030 and weighting by build stage, the index expects about 768 MW running by 2030.
At that level it would use about 5,046 GWh of electricity a year, roughly what 468,000 US homes use (EIA average of about 10,800 kWh per home), and add about 126.8 MMcf/d of natural gas burn on an average day, counting both on-site generation and the region's gas-fired power plants.
Its rating is driven by gas: most or all of its power comes from on-site or dedicated gas generation, so the strain falls on pipelines and local gas supply rather than the transmission grid. Rated 4 of 4 bolts. Solid bolts mean the campus is operating or under construction.
Research note. dcmap: 4,000 MW onsite generation. Fuel assumed natural gas; verify.
