Just a short trip from London lies Potters Bar, a town separated from the village of South Mimms by 85 acres of farmland, with hedgerows tracing through the landscape. In one of these fields, a solitary oak tree has become a focal point for local protest. A sign affixed to its trunk declares, “NO TO DATA CENTRE.” The catalyst for this uprising came in September 2024, when a developer sought permission to construct one of Europe’s largest data centers on this pastoral land. As news spread, a Facebook group emerged, rallying over 1,000 locals to oppose the project. Despite their efforts, the local government approved the planning in January 2025. By October, Equinix, a multinational data center operator, acquired the land with plans to commence construction this year.
On a dreary January afternoon, I met with Ros Naylor, an admin of the protest group, and a handful of local residents near the site. They voiced their concerns, focusing on the loss of green space—a valued escape to nature and a shield against the encroaching urban sprawl. “Walking through this area is essential for mental health and wellbeing,” Naylor emphasized. As the UK government strives to meet the increasing demand for data centers crucial for AI development, such facilities are sprouting nationwide. Yet, for those living nearby, the promise of economic growth or enhanced smartphone capabilities offers little solace for the disruption to their rural lifestyle.
In recent years, the UK government has redefined certain green belt lands as 'grey belt,' allowing construction on underperforming areas. This change, coupled with the classification of data centers as critical infrastructure, has paved the way for numerous new developments. Global AI labs are poised to invest trillions in infrastructure to advance their models, but these projects are often met with resistance. When Potters Bar’s data center was approved, authorities deemed the farmland grey belt, influenced by governmental support for the data center industry. They argued that economic benefits outweighed the loss of green space. Jeremy Newmark, leader of Hertsmere Borough Council, noted that the land was a low-performing green belt patch, challenging the romanticized view of lush countryside.
The protest group questions this reclassification, especially when a nearby housing proposal was rejected to preserve green belt land. “How can one field be dispensable and another invaluable?” asked Eamonn Lynch, a local resident. They feel overwhelmed by the planning process, claiming their objections were overshadowed despite significant local opposition. Efforts to overturn the decision through official complaints and appeals have so far been unsuccessful. Newmark insists the consultation process was thorough, and each application is judged independently.
In response to protests, the local government underscores the economic benefits of the data center, anticipating over $5 billion in investment, 2,500 construction jobs, and 200 permanent positions. The facility is expected to generate $27 million annually in property taxes, benefiting local services. Newmark argues that such an investment will significantly impact the local economy, potentially attracting more high-tech businesses. For Equinix, this site is strategically located near major population hubs and existing facilities, offering low latency and strong power infrastructure. Andrew Higgins of Equinix assures that half the site will remain green, enhancing biodiversity with planned ponds, wetlands, and meadows. He hopes to balance development with environmental responsibility.
Equinix must still complete a final planning phase before construction can begin, facing a determined protest group intent on challenging every step. Michael Batty, a planning expert, highlights the importance of public objection in Britain’s planning system.
In January, after the group dispersed, I walked the farmland with Janet Longley, a long-time resident. As her dog, Lola, bounded through the muddy fields, she reflected on the need for data centers and the digital services they enable. Despite this understanding, Longley laments the loss of a beloved green space and wishes the project could be relocated. “Beauty is in the eye of the beholder,” she mused, gesturing across the landscape. “It is actually beautiful. Just maybe not so much today.”
