UK Data Centre Expansion: Judicial Review Risks and the Renewables Imperative

The UK is poised for a substantial uplift in its data centre infrastructure, with nearly 100 new developments expected over the next five years - an increase of almost 20 per cent over existing facilities. This surge is driven by escalating demand for artificial intelligence processing power and fuelled by significant investments from major firms, including a £10 billion AI-focused centre in Blyth backed by Blackstone, and hundreds of millions of pounds from tech giants such as Google and Microsoft.

Energy and Water Pressure: Risks to Project Viability

Several factors amplify the risk of legal scrutiny during the planning process:

  • Water consumption: Medium-sized data centres may use around 110 million gallons annually for cooling, while hyperscale facilities can consume up to 5 million gallons daily. Notably, in water-stressed areas such as South-East England, proposals such as the Elsham Tech Park hyperscale development have triggered strong objections from Anglian Water, which warned of threats to local water supplies, sewer infrastructure and environmental harm. Similar concerns arose in Culham, Oxfordshire, where an AI Growth Zone near a planned reservoir raised alarm over exacerbated regional water shortages.
  • Energy demand: Data centres currently account for around 2.5 per cent of national electricity consumption, with projections rising to 6 per cent by 2030, and potentially nearing the total energy demand of the industrial sector by 2050.
  • Planning friction: These sustainability pressures conflict with the government’s push for AI and data centre growth, as seen at Teesworks – the UK’s designated second AI Growth Zone – where energy and water concerns have intensified tensions between technology and energy departments.

Judicial Review Risk: When Environmental Oversight Meets Planning Aspirations

Given the environmental sensitivities, data centre proposals – especially those involving large scale sites or greenbelt land – are exposed to increased risk of planning objections and possible judicial reviews. In locales described as greenbelt, objections focused on openness, visual harm and ecological impact have already succeeded in resisting data centre developments.

This highlights an urgent need for:

  1. Robust environmental impact assessments – particularly regarding water resource dependency and energy sourcing – to mitigate grounds for legal challenge.
  2. Transparent sustainability commitments, including renewable energy supply and closed-loop or water-efficient cooling systems.

Projects that fail to substantiate credible mitigation strategies may be vulnerable to legal intervention by residents, regulators, or infrastructure providers.

Renewables: A Strategic Shield and Sustainability Solution

To safeguard project viability and support resilience, developers should prioritise renewable and low-impact energy and cooling strategies. A number of methods present viable paths:

  • Renewables commitment: Operators like AWS already back wind and solar projects, but scaled data demand may necessitate supplementary zero-carbon baseload sources such as nuclear power.
  • Innovative cooling: Closed-loop systems and largely waterless cooling methods are gaining traction. In fact, 64 per cent of data centres in England now use under 10,000 m³ of water annually – less than a typical leisure centre – thanks to advances like waterless or closed-loop cooling.
  • Heat reuse and wastewater: Recycling waste heat into local heating networks or repurposing treated wastewater for cooling can further reduce environmental impact.

Conclusion

As the UK pursues economic and technological leadership through expanding data centre capacity, environmental resilience must remain central to planning and delivery.

Greece’s Renewable Energy Market: Accelerating Permits and Unlocking Finance

Greece is entering an important phase of its renewable energy transition. The opportunity is no longer simply about increasing renewable capacity. The focus is increasingly on how quickly viable projects can move from development and permitting to financing and construction.Greece’s updated National Energy and Climate Plan sets an ambitious direction for the market, including a target for renewable sources to provide around 82% of domestic electricity generation by 2030.For developers and investors, however, ambitious targets alone do not deliver projects. Permitting, grid capacity, environmental constraints and the risk of administrative challenge all influence whether a consented project can reach financial close.Recent reforms seek to address the first of those issues. The question is whether financing structures can evolve alongside them.

Norway’s Data Centre Expansion: Power, Planning and Permit Challenge Risk

Norway’s abundant renewable electricity, cool climate and political stability have made it an increasingly attractive location for data centre investment.The latest development is Microsoft’s acquisition of a site at Kvål in Sandnes, part of the Stavanger region, for a proposed 25 MW data centre. The project was announced on 30 June 2026 and is intended to complement Microsoft’s existing Norway East cloud region. The 64-acre site was reportedly acquired for NOK 153.6 million and is already zoned for industrial use.At first sight, the development appears to demonstrate many of the characteristics investors seek: an established technology operator, a supportive municipality, suitable land and access to Norway’s predominantly renewable electricity system.However, it also illustrates a wider issue emerging across the Nordic data centre market. Securing land and planning support is only part of the delivery challenge. Access to power, compliance with a developing regulatory framework and the ability to withstand political or legal scrutiny are becoming equally important.

Portugal’s Green Map: Can Renewable Acceleration Areas Deliver Greater Permitting Certainty?

Portugal has taken an important step towards reshaping the way renewable energy projects are planned and permitted.On 17 June 2026, the Government opened a public consultation on its proposed “Green Map”, identifying areas considered particularly suitable for new wind and solar development. The proposal includes 1,302 priority areas, comprising 792 areas for solar projects and 510 for wind.The selected areas are located within 10 kilometres of existing grid connections and have been mapped with the aim of avoiding significant environmental and licensing constraints.For developers and investors, the attraction is clear. Greater visibility over suitable land, grid proximity and environmental constraints could reduce early-stage uncertainty and shorten the route to consent.However, acceleration areas do not eliminate legal risk. They change where that risk arises.

Germany’s Planning Reforms: Faster Real Estate Development, New Legal Uncertainty

Germany’s real estate market entered 2026 with tentative signs of recovery.After three consecutive annual declines, permits were issued for approximately 238,500 residential units in 2025, an increase of 10.8% compared with 2024. The improvement suggests that the market may be beginning to respond to stabilising conditions, public support and efforts to reduce regulatory barriers.However, Germany remains well below the level of development required to address its housing shortage. Against this background, the Federal Government is pursuing reforms intended to accelerate, simplify and digitalise the planning system.The reforms present a significant opportunity for developers and investors. They also raise an important question: does a faster planning system necessarily introduce more legally secure development?

Repowering Europe’s Wind Farms: Greater Output, New Permitting Challenges

Across Europe, a growing number of wind farms are approaching a critical point in their operational lives. Developers and asset owners must decide whether to extend operations, decommission the site or replace older turbines with modern, more productive technology.Repowering is increasingly emerging as the preferred option. It can substantially increase generating capacity while making continued use of established sites, grid connections, access routes and operational experience.However, repowering is not simply a matter of replacing old machinery. Modern turbines are generally taller, more powerful and more visually prominent. Projects can therefore require extensive environmental assessment, renewed planning or energy consents and, in some cases, modifications to grid and transport infrastructure.For developers, funders and their legal advisers, the central issue is how to capture the considerable benefits of repowering while managing the permitting and challenge risks created by a materially different development.

Renewable Energy and the 2026 Statistical Review of World Energy

The global energy transition has reached an important stage. Renewable energy is no longer simply supplementing conventional generation. It is becoming the principal source of growth in the world’s energy system.The Energy Institute’s 2026 Statistical Review of World Energy records that global energy demand exceeded 600 exajoules for the first time in 2025. Renewables made the largest contribution to the increase in total energy supply, the first time this has occurred outside a period of economic recession. Solar accounted for approximately 71% of that renewable growth.These figures demonstrate the scale of investment flowing into new generation. They also point towards the next major challenge for governments, developers and their legal advisers: delivering the networks, connections, storage and planning approvals required to turn installed capacity into reliable electricity.
