New plans for Teddington and Ham Hydro are displayed at a public exhibition today.

The application, submitted to Richmond Council last month, replaces the previous proposal from November 2011, which has since been withdrawn.

Under the new proposals, the Teddington and Ham Hydro group want to demolish a section of the weir and install three reverse-engineered Archimedean screw turbines to generate hydro electricity.

The design also includes a new fish and eel pass and sluice gate, cable routes to the substation, maintenance access to that section of the weir and a plant room.

The development at Teddington Weir will generate electricity from renewable energy sources, estimated between 1.5 to 1.9GWh annually, which is the equivalent to the electricity demand of 500 to 600 homes.

The design incorporates features from the current weir structures and will be smaller than many elements of the current weir structure, developers have said.

In a letter to Richmond Council’s planning department, Steve Jarvis, managing director of Teddington and Ham Hydro, said the group had carried out extensive consultation at an informal level with all interested parties since the submission of the previous application.

Mr Jarvis added the application represents the group’s latest thinking on design proposals and technology for a turbine to generate green electricity and said he believed the council would be able to grant approval for the "exciting opportunity" which will "contribute to a more sustainable lifestyle for residents".

Since the application was submitted, more than 220 letters of comment and objection have been received by the council.

The public exhibition takes place at Tamesis Club, Trowlock Way, Teddington, from 7.30pm to 9.30pm.
