Bath and North East Somerset Council is planning to allocate £1.85 million to develop detailed plans for a hydroelectric power plant situated prominently in front of Pulteney Bridge. This initiative aims to modernize the city’s energy infrastructure while preserving its historic landmarks.
The existing Pulteney Radial Gate, adjacent to the iconic stepped Pulteney Weir, dates back to the 1970s and is now considered to be at the end of its operational life. The council is exploring various replacement options, including a cutting-edge hydroelectric scheme capable of generating sufficient electricity to power Bath’s Guildhall using the Avon River’s flow.
Funding for this phase of the project will come from corporate-supported borrowing and will cover the preparation of a comprehensive business case along with design work. However, additional financial resources will be required for the construction of the hydroelectric facility should the project proceed.

Last year’s feasibility study underlines the project’s potential, with Council Leader Kevin Guy describing it as “the most exciting and ambitious inner-city hydroelectric project in Europe.” This initiative aligns with the council’s wider goal to achieve carbon neutrality across its estate by 2030.
Bath has a rich tradition of innovative use of its natural and historical resources. The city’s famed hot springs, which first attracted Roman settlers over two millennia ago, currently provide heating for key cultural sites including Bath Abbey, the Roman Baths, the Pump Rooms museum complex, and the Bath World Heritage Centre.
The hydroelectric proposal is part of the capital budget, distinct from the revenue budget that manages day-to-day expenses like adult social care. Despite financial pressures leading to a proposed council tax increase of 4.99%, strict regulations prohibit using council tax revenue for capital projects. Borrowing costs, however, will impact the revenue budget through interest expenses.
A council paper highlights that the Environment Agency, currently responsible for operating and maintaining the radial gate, is seeking to transfer ownership to the council. As part of the decarbonisation program, the council is advancing the business case for various options, including utilizing the existing wide gate channel for hydroelectric power. Any hydroelectric installation will be coordinated with ongoing redevelopment work related to Bath Rugby’s new stadium plans along the riverside close to the radial gate.
The capital and revenue budgets will be reviewed by the council cabinet on February 12 and voted on at the full council meeting at Bath Guildhall on February 24.
