The entire energy market is a weird thing.
We produce natural gas and crude oil. This is extracted by companies we sell licences to, who extract it, then as it now belongs to them, they put it on the energy market and we buy it at market prices.
Its going to go the same way with the electricity from the windfarms off the coast of Aberdeen.
The government(English) are proposing laying powerlines from Aberdeenshire, the length of the country and over the channel to the EU, where they intend to sell it.
Any excess we need we'll buy from the market at again market rates.
Rather obviously than laying powerlines to N/Scottish/UK communities and saving the consumer money with locally and cheaper to produce renewable energy.
