A leading environmental energy producer Ecotricity has delivered a damning critique of the proposed the Cardiff/Penarth power-generating tidal lagoon – a huge scheme which would construct a massive 40-foot-high concrete curtain across the sea-front of Penarth.
The founder of Ecotricity, Dale Vince, has called on the UK government to “resist the pressure” to grant support for tidal lagoon schemes being promoted by Tidal Lagoon Power PLC – comprising both the Swansea Bay tidal lagoon and the similar – but much larger – Cardiff/Penarth Tidal lagoon scheme.
In a letter to the Energy Secretary Mr Vince says it’s far better to build tidal lagoons OFFSHORE – well away from the coast – because they can “produce power at half the cost” of lagoons like Swansea Bay and Cardiff/ Penarth both of which would be ( if built) “connected to the foreshore” and would be far less efficient.
Dale Vince also says that lagoons built out to sea have the advantage of “significantly lower environmental impact on the inter-tidal zone, as they don’t kill as much wildlife, and use less rock for construction’”.
Mr Vince also attacked the way in which the Tidal Lagoon Power PLC’s proposals were being dealt with. He said says “We need a competitive tender and not a sweetheart deal with just one developer” . He also noted that an offshore tidal lagoon could be built at “a quarter” of the kind of costs currently being bandied about.
The hand-wringing BBC News – ever the cheerleader for coastal tidal lagoons – said Eco-Tricity’s comments “couldn’t have come at a worse time” for Tidal Lagoon Power PLC – the company which is promoting both the Swansea Bay and the controversial Cardiff/Penarth power lagoon project. People in Penarth may come to the opposite conclusion.
