Summary

• Early planning material describes a Charlton data-centre development capable of roughly 180MW.
• The current filing is an environmental-impact scoping request rather than full planning approval.
• Housing, power, cooling, heritage, and regeneration pressures will shape whether large digital infrastructure can occupy the site.

London’s appetite for computing infrastructure is beginning to compete directly with other claims on scarce urban land, with an east London proposal placing a large data centre, housing ambitions, industrial heritage, electricity capacity, and neighbourhood regeneration inside the same planning argument.

Charlton Gateway is being proposed on former industrial land beside the Thames in Greenwich, where early planning material describes a substantial data-centre development with a dedicated electricity substation and supporting commercial space. Industry reporting puts the proposed computing capacity at around 180MW.

The current filing with the Royal Borough of Greenwich is not full planning permission for a finished scheme. It seeks an environmental-impact scoping opinion, meaning the design and detailed environmental assessment can still change before a substantive planning decision.

That distinction is important because the development remains at an early stage, although the proposal already demonstrates the scale of infrastructure being considered inside London as demand for cloud and AI computing continues to grow.

Compute competes for urban land

Charlton Riverside has long been associated with large-scale regeneration, including housing across the wider district, while parts of the former Stone Foundries land have moved through previous development proposals. Introducing a large data centre places nationally significant digital infrastructure into land that remains politically connected to London’s housing and regeneration pressures.

Large computing facilities require an unusual combination of electricity, fibre connectivity, physical security, transport access, and enough space for buildings, substations, cooling systems, and backup power. Once a site possesses those characteristics, its value for digital infrastructure can diverge sharply from superficially similar urban land.

Power availability is particularly important. A suitable grid connection can make one industrial parcel viable for high-density computing while another nearby site cannot support the same use without extensive network work.

That creates a planning question extending beyond ordinary property economics. Data centres can serve companies, public services, financial markets, and consumers across a much wider region, while their physical footprint and infrastructure demands remain concentrated within one neighbourhood.

Cooling and electricity enter the planning debate

The developer says the scheme would use dry cooling rather than continuously consuming fresh water for heat rejection, with a finite amount of water reused within the system. A dedicated substation and backup generators are also expected to form part of the facility.

Those engineering choices have consequences outside the operator’s own efficiency calculations. Water consumption has become politically sensitive around data-centre development, while large electrical connections can affect local and regional infrastructure planning and backup generators introduce questions around noise, emissions, and operating conditions.

The project is also considering whether waste heat could contribute to a low-carbon district-heating network. Such systems can recover energy that would otherwise be discarded, although their usefulness depends on nearby customers, suitable temperatures, commercial agreements, and infrastructure connecting heat sources with buildings capable of using it.

Waste-heat recovery should therefore be treated as an additional infrastructure opportunity rather than an automatic offset for the electricity consumed by the computing equipment itself.

Industrial heritage adds another constraint

The Charlton site includes buildings associated with the former Stone Foundries, giving the development a heritage dimension alongside power, housing, and environmental considerations. Any full proposal will have to establish how the retained industrial character and surrounding regeneration plans are affected by the scale of the data-centre buildings and supporting equipment.

National policy has become more supportive of data centres since the UK government designated them as Critical National Infrastructure in 2024 and planning policy began giving greater recognition to their specific locational requirements.

National importance does not remove local trade-offs. A facility serving remote customers may deliver economic value far beyond Greenwich, while buildings, construction traffic, substations, generators, and land consumption remain physically concentrated in Charlton.

London’s digital economy needs physical space

Those tensions are likely to become more common as computing demand grows. London remains one of Europe’s largest data-centre markets because of its dense concentration of companies, finance, networks, and customers, but those same characteristics make land expensive and create fierce competition with housing, logistics, commercial property, and public infrastructure.

Large AI training facilities can increasingly move towards secondary locations with cheaper land and power, whereas latency-sensitive cloud and enterprise workloads still generate demand closer to major cities. London therefore has incentives both to push the largest compute campuses outward and to retain substantial capacity near the businesses and networks consuming it.

Charlton Gateway places that contradiction onto a single riverside development site. Before any servers arrive, the scheme has to establish whether the value of keeping major digital infrastructure inside the capital justifies the electricity, land, heritage, and planning compromises required to put it there.
