Cardiff East Park and Ride data centre campus (Curtis Hall), Llanrumney
Curtis Hall Ltd, the site owner, has applied to Cardiff Council for three data centres, an on-site substation and energy facilities on the 40-acre Cardiff East Park and Ride site in Llanrumney (hybrid application 26/00109/HYB). A 150MW grid connection is reported for full build-out but may not be available until between 2030 and 2034, so the developer proposes a temporary gas-fired energy centre of up to about 49.9MW, modelled to run from 2028 to 2033. In September 2026 the Welsh Government issued a holding direction, so Cardiff Council cannot grant permission while ministers consider calling it in.
