Even Scotland’s energy minister, Fergus Ewing, called the closure of Longannet “a national scandal”, laying the blame squarely on “Westminster” – which is curious considering that his government’s policy is that by 2020 Scotland should produce 100 per cent of its electricity from “renewables”. (In other words, that it should be able to rely on unsubsidised back-up from fossil fuel plants in England when there is too little wind, while selling heavily subsidised wind power back to England when there is too much.)
