London City Hall developing data centre policy to tackle energy concerns

TL;DR: London City Hall is drafting a new policy on data centres to manage their growing impact on the capital’s power and water supply. Housing projects in west London have already been delayed because data centres consumed available grid capacity.

The Greater London Authority is developing a specific data centre policy after officials acknowledged the tension between economic growth and environmental strain. Megan Life, the GLA’s assistant director for environment and energy, told the London Assembly Environment Committee that the policy would aim to retain economic benefits while addressing power consumption.

Grid pressure and housing delays

Deputy mayor for the environment Mete Coban described data centres as bringing “big benefits” alongside “massive challenges” for London’s energy and water resources. He warned against allowing “a few global corporations” to take without giving back, adding that the problem extends well beyond London.

The push for a formal policy follows a December report from the London Assembly Planning and Regeneration Committee, which found that several west London housing developments had stalled because data centres had used all available grid capacity. At the end of February, campaigners staged two days of protests in London over unchecked data centre expansion.

Industry responses

Several large data centre and AI companies, including Microsoft and OpenAI, have introduced policies aimed at addressing environmental concerns around their planned build-outs. However, demand for AI compute continues to drive expansion plans across the UK, with London remaining a primary location for new facilities.

Looking forward

The new policy will need to set clear boundaries on resource allocation without discouraging investment. With the UK government simultaneously promoting AI infrastructure growth and cities competing for data centre business, London’s approach could set a template for other regions grappling with the same trade-offs.
