it is, chaos happens. here, we have many, many wind turbines and the government's agenda is to shut down all lignite power plants, even the brand new, 560 MW, ptolemaida V. They are using them as peak load power plants, which is a very inefficient way to use a lignite (thus coal) power plant, because they were designed to be used as base load plants, thus to run for 1 1/2 years continuously, 24/7. They need 7 1/2 hours from the time the boilesr starts to heat up, until the unit synchronises and the circuit breaker closes. In the beginning it needs LOTS of diesel oil to pre-warm the boiler until it's hot enough to burn lignite and produce enough super heated steam to run the turbine. Now they use it
4-5 hours a week which is VERY inefficient. It is due to over-generating of (supposed) clean electricity by wind turbines and photovoltaics, if it exceeds on-the-fly demand the frequency of the grid rises with risks of damage to equipment and, even blackout. So they'll have to stabilize the grid by shutting down conventional units, when that happens. Lignite or (God forbid) nuclear don't provide that flexibility, so they have exchanged them with gas turbine units, that run on natural gas, which can be shut down and fired up again at will. at their best they're combined cycle, with the majority being open cycle, unfortunately. The natural gas, of course, comes from Russia. The same situation is all over Europe.
