London Eye Architect Proposes 11 Billion Pound Tidal Power Station Off Somerset Coast

Julia Barfield, the architect behind London’s iconic Eye and Brighton’s i360 observation tower, has unveiled an ambitious £11 billion proposal for a tidal power station spanning 14 miles off the Somerset coast. The West Somerset Lagoon project represents a significant opportunity for institutional investors seeking exposure to renewable energy infrastructure whilst addressing Britain’s rapidly escalating electricity demand driven by artificial intelligence deployment.

The proposed structure would arc from Minehead to Watchet, incorporating 125 underwater turbines designed to harness the Bristol Channel’s second-highest tidal range globally. With a maximum output capacity of 2.5 gigawatts, the facility would generate electricity sufficient to power approximately 2 million homes, approaching the anticipated peak output of the nearby Hinkley Point C nuclear power station located 12 miles east.

The project consortium, led by chief executive Aidan Clegg, has secured interest from potential investors contingent upon government support. The developers position tidal power as a more predictable renewable source compared to wind and solar energy, despite intermittent generation during tidal transitions. The backers project a 120-year operational lifespan, which would yield power generation costs competitive with nuclear alternatives on a lifecycle basis.

Britain’s National Energy System Operator has forecast that electricity demand from datacentres will treble by 2035, with artificial intelligence workloads accounting for the largest proportion of commercial sector demand growth. Government estimates suggest overall electricity consumption could more than double by 2050. The West Somerset Lagoon proposal directly addresses these infrastructure requirements whilst maintaining alignment with decarbonisation objectives.

The development includes ancillary commercial elements designed to enhance project economics and regional development. Plans encompass a pedestrian and cycling pathway atop the semi-circular barrage, a water-sports marina, lido facilities, and an observation tower. The designers have preliminarily explored incorporating datacentres within the structure, leveraging seawater cooling to reduce operational expenditure. Additional revenue streams may include marine aquaculture operations for oysters, mussels, and seaweed cultivation, alongside floating solar panel installations.

Rachel Gilmour, the local Member of Parliament, has endorsed the initiative, emphasising its potential to transform Minehead, currently ranked among the most deprived 20 per cent of British localities. The project promises substantial employment creation and economic regeneration for West Somerset through construction phase opportunities and permanent skilled positions.

The Department for Energy Security and Net Zero has indicated receptiveness to well-developed tidal range proposals demonstrating value for money. The government’s AI Energy Council, comprising the National Energy System Operator, EDF, Microsoft, and Google, is actively evaluating solutions to address AI-related energy demands whilst supporting low-carbon power infrastructure for datacentres.

Current UK energy policy acknowledges tidal and wave energy’s potential role contingent upon cost reduction. The West Somerset Lagoon represents the latest iteration of proposals to exploit Severn estuary tidal resources, following previous concepts including lagoons near Bristol and a full barrage between Cardiff and Weston-super-Mare. The current sponsors assert their design avoids disruption to navigation channels serving Bristol and Cardiff ports whilst remaining outside protected conservation areas and local nature reserves.

The proposal emerges at a critical juncture as policymakers balance accelerating AI adoption against climate commitments. The project offers investors exposure to predictable renewable energy generation, infrastructure development, and regional economic transformation, subject to securing governmental backing and navigating environmental assessment processes.
