- Not verified · A comparable IT power capacity has not been verified in the cited sources. Cabinet counts and construction spending are not converted into electricity demand.
The first phase is a future development in the operator timeline. Neither its construction status nor its target opening date proves a current grid connection, power draw or operating service. No energy comparison is shown without a verified capacity boundary.

Explore a capacity scenario
Illustration only, not measured consumption. This uses the proposed full-campus IT capacity for 24 hours. It excludes cooling and other building loads; no efficiency multiplier is assumed. It does not estimate current grid demand.
| Assumed IT load | IT energy per day | Household electricity equivalent |
|---|
| 25% | 540 MWh | About 78800 homes |
| 50% | 1,080 MWh | About 157700 homes |
| 100% | 2,160 MWh | About 315400 homes |
How the comparison works
Capacity is a power rating in megawatts (MW). Energy is power multiplied by time: MW × 1,000 × 24 hours × assumed load fraction gives kilowatt-hours (kWh) per day.
Divide that daily energy by 2,500 ÷ 365 to compare it with a typical household’s average daily electricity use. We use Ofgem’s GB single-rate medium benchmark, effective 1 July 2026. It covers electricity only, not gas, and is not a measurement of homes in this area. Real households and daily demand vary.
What public data can tell us
DESNZ publishes meter-based estimates for groups of data centres, with some areas combined to avoid disclosure. Those totals cannot be assigned to individual facilities. We need site-specific, dated energy disclosures or an authorised meter feed before showing actual site consumption.
