Tidal power interest swells

Swansea bay tidal lagoon

A second renewable energy firm has announced ambitions to build tidal lagoons in the UK.

Ecotricity told ministers it could deliver energy from the tides cheaper than the proposal put forward for Swansea.

Tidal Lagoon Power’s pioneering 320MW Swansea Bay tidal project (pictured) received planning consent from the Department of Energy and Climate Change last summer.

But contract for difference negotiations are ongoing and the government this month announced a review of the value for money offered by tidal lagoons.

Tidal Lagoon Power said that its required strike price for Swansea Bay was under £100/MWh if the project was linked to the successful delivery of a second, bigger lagoon.

Ecotricity said it would release its own plans in the summer, hinting it believed tidal projects could be delivered for close to £90/MWh.

Ecotricity founder Dale Vince said: “The government has been agonising for a while about what level of support to give to the first tidal project in Britain.

“We’re hoping this review will lead to the government supporting tidal energy in Britain and doing it in a way that will enable competition, and through that value for money – enabling tidal mills to achieve their true potential in Britain.”

A Tidal Lagoon Swansea Bay spokeswoman said: “The emergence of a competitive marketplace for the future is a part of Swansea Bay Tidal Lagoon fulfilling its role as a pathfinder.”

Tidal Lagoon Swansea Bay chair Keith Clarke said earlier this month: “We welcome the independent review into tidal lagoon energy across the UK.

“We are confident that tidal lagoons are no longer a footnote in UK energy policy: the time has now come for tidal power and we hope that the review process will ensure we get to deliver, long term, home grown and cost effective electricity for many generations to come.”
