Unlikely, if you look one there at the pie chart for average use of the past year, you'll see that 41% fossil fuel, 26% renewable, 17% Nuclear, 7% Biomass. We are running down the last few nukes, and it'll probably take a decade or more to get the new ones, if that ever happens. For renewable, one should read 'intermittent' (it is mostly wind turbines), and the back fill for that is gas-turbines, so we need equal fossil fuel generation capacity to the wind generation capacity. There are periods where our little island has weeks without wind, as has happened over the last year, including during the last winter. If you look at the production graphs, specifically the past year (weekly averages), you can see those spikes where there was no wind, and we had to fully utilise all of out fossil fuel plans - including inefficient OCGT (and possibly diesel) plants. Unless and until we can have an efficient storage mechanism (batteries can not cut it), we will be dependent upon gas turbine generation. So one can anticipate high energy costs for around 20 years, until we get new nukes online - if we ever do.
