The windfarm off the South Coast was completed in 2018, they are talking of more than doubling the size of it and already the turbines are twice as efficient as the ones used 5 years ago. As long at the pylons they put in are good for 20 or 30 years then it is upgradeable and profitable if the companies are prepared to wait.& only yesterday there was an article by Ng boss stating they needed electric prices to rise at least 70% to fund wind farm construction because at the present rates no one wants to build them.Personally I cannot see why rates have to be fixed so that they will build them.It should be the same as anything else you fund & build it your self & hope to profit from it.
While I was looking to see when it was completed, I discovered it isn't as French as I originally thought, it's always had E.On all over it but, Mr Google tells me - " RWE Renewables UK Limited is the majority shareholder with 50.1 per cent of the shares, Canadian energy company Enbridge has 24.9 per cent and Equitix with 25 per cent. E. ON UK developed the project through to consent and managed the construction on behalf of all three owners."
