600 megawatts for £624 million is £1.04 million per megawatt.
450 megawatts for £596 million is £1.32 million per megawatt.
Unbelievably, Ofgem's preferred solution is *worse* value for money - it costs 27% more per megawatt!
Most people would bite your hand off for that kind of deal. Not Ofgem, though. They have to "protect consumers from additional costs".
Total cost to the UK consumer: £2 per household, per year.
The 450 megawatt link, at £596 million, would cost about 54p per household, per year.
Ofgem are literally quibbling over 3p.
It gets worse, though. For Orkney, Ofgem are thinking about using something called the "Competition Proxy" model.
If you want that in a nutshell: "we'll take a guess."
Is it any wonder Scotland is moving towards independence?
I also have a more general thread about renewables, storage, nuclear, grid upgrades and (inevitably) UK Government policy. It's particularly relevant in the context of Friday's #powercut.
