Along with plants that run on renewable sources of energy, conventional power stations will continue to be an essential part of electricity supply in the decades ahead. And they are becoming more and more flexible.
Base, intermediate and peak load – on some days, the minimum level of electricity consumption amounts to less than one quarter of peak consumption. And the amount of electricity supplied to the grid has to match up to consumption all the time, in order to maintain network stability. The size and duration of the load fluctuations dictate the requirements imposed on power generation and, in turn, on the power stations that are used. Accordingly, security of supply is typically based on the co-ordinated use of suitable energy sources and power station variants.
