BBC finds four planned UK data centres weighing on-site gas power while they wait years for a grid connection
What changed
BBC File on 4 Investigates reports that four planned large UK data centres are considering gas-fired generation on site after the Budget said developers may build their own power where no grid connection is available. The projects named are Acre Slough west of London (gas engines of up to 49.5 MW while it waits at least 10 years for a National Grid connection, the developers say), Wapsey's Wood in Buckinghamshire (a proposed 200 MW gas power station until grid capacity arrives, currently not expected until 2040), Quest Park in Bedfordshire (a 1 GW site whose energy mix is still a 'work in progress', its director says) and a Cardiff site seeking a temporary energy centre with up to 49.9 MW of turbines for up to five years. The BBC calculates that together they would need 1.3 GW and could emit about 4.1 million tonnes of CO2 a year if run continuously at full capacity (BBC estimate). Ofgem says data centre developers are seeking connections totalling 72 GW, against UK peak demand of 45 GW last year. The government says any behind-the-meter generation will be tightly controlled, time-limited and allowed only for exceptionally strategic projects. All four projects say they intend to connect to the grid when it can meet their needs.
