Plans to demolish a park and ride facility in Cardiff and replace it with a massive data centre have drawn sharp criticism from local activists and Members of the Senedd (MSs). The proposal, submitted by Curtis Hall Limited to Cardiff Council, would see the Cardiff East Park and Ride in Llanrumney, which currently provides free parking and shuttle services to the University Hospital of Wales, transformed into a data hub.
Community Concerns Over Energy and Water Use
The application describes data centres as essential national infrastructure supporting cloud computing, AI, and digital services. However, local residents and Acorn, a tenants' union, have launched a petition opposing the plans. Hannah Dahwa, a 40-year-old resident, voiced concerns about the facility's potential energy and water consumption, claiming it could use the equivalent of 100,000 homes' electricity and 1,800 homes' water annually.
Ben Hall, a director at Curtis Hall Limited, did not dispute these figures but noted they represent the upper end of potential impact, not typical daily operations. He explained that actual usage depends on the end user, computing type, chip generation, and cooling technology.
Impact on Household Bills and Healthcare Access
Ms Dahwa warned that the data centre's power demands could raise household bills, but Mr Hall refuted this, stating that commercial connections do not affect regulated household energy prices. He argued that locating major demand in a net energy exporting region like south Wales supports grid investment and clean power development.
The proposed loss of the park and ride has sparked particular outrage. Ms Dahwa emphasized that the service is vital for hospital staff and patients, and its removal would harm wellbeing. Dan Snipe, an Acorn organiser, described the park and ride as a lifeline for residents in Llanrumney, Rumney, and Pentwyn, warning of chaos if it disappears.
Cai Parry-Jones MS, representing Caerdydd Ffynnon Taf, echoed these concerns, stating that the park and ride is essential for healthcare access. He criticized the plan, especially given new developments in the city. In response, Mr Hall noted that Cardiff Council brought the site forward due to funding loss and under-utilisation, and that alternative transport solutions would be developed with the health board.
Environmental and Wildlife Impact
Ms Dahwa also raised alarms about noise, air quality, and damage to green space and wildlife, including kingfishers, bats, and otters. She claimed the data centre's water use and heat would destroy local ecosystems. Mr Hall countered that ecological assessments have been conducted, with plans to retain valuable habitats and deliver a net biodiversity benefit, including off-site dormouse habitats and bridges.
The Rhymney Trail, a public right of way through the site, would be retained and enhanced with better surfacing, signage, and seating, according to Mr Hall. Concerns about flooding during construction were also raised, particularly for homes on Ball Lane.
Political Opposition and Next Steps
Two other MSs for Caerdydd Ffynnon Taf, Zaynub Akbar and Nicker Carter, have opposed the plans, citing transport and environmental concerns. They have written to Cardiff Council to ensure residents' voices are heard. The plans remain under consideration by the council.
