The report presents the results of scientific and technical support for ensuring an uninterrupted operation of coal-fired power plants using non-design fuels. These works have been carried out by the Institute of Thermal Energy Technologies of the NAS of Ukraine since 2014. It is shown that solid fuel power generation is today a critically important factor of stable heat and power supply thanks to the possibility of using both local and available on the world market gas coal, as well as fuel biomass, which makes it possible to ensure distributed electricity generation that is less vulnerable in martial law conditions and to satisfy a significant part of heating needs. It is substantiated that in Ukraine, as well as in the world in general, for at least another 10-20 years, along with nuclear power plants, two systems of energy production will function in parallel – based, respectively, on renewable sources and fossil fuels, which, in particular, is due to the need to regulate power levels in power system and ensure an uninterrupted power supply during the transition period.
