From the info I got on one of the conferences on energy saving, the coal is used in addition to nuclear because of the spikes in electricity usage. So nuclear is only covering whatever is the lowest level throughout the day, while coal plant is being started two times a day to cover the spikes.
- tomatocracy 7y agoCoal plants are not able to rapidly start and stop like that and still operate efficiently or at peak capacity - their startup time is measured in hours not minutes. Gas (particularly OCGTs - CCGTs are usually less efficient than OCGTs if you do that with them) does that. Coal can be used in some markets seasonally (ie to supply additional baseload demand for summer AC / winter heating depending on local needs).
