Rapid-response gas-fired stations, mainly in England, and some smaller pumped hydro such as Ben Cruachan in Scotland, supplement this.
All of these play a role in Scotland’s generation activities. With the intended shut-down of existing nuclear and fossil-fuel base-load facilities and increasing reliance on wind power, many more hugely expensive Dinorwigs will be needed.

Hide AdDenmark, for example, relies on Norway’s hydro and pays for the privilege.
I may be mistaken but I think the wind/nuclear cost ratio given by Tony Trewavas (Letters, 3 March) does not fully allow for the foregoing and so is likely to be a very big underestimate.
Reliable on-demand wind-generated electricity is a hugely expensive commodity.
