Review article

Large thermal power plants (TPP) located within the boundaries of urban areas usually use diesel or black oil as a reserve fuel (RF). In some cases, coal is also used. That has a negative impact on the natural environment of the city. In accordance with this, the new procedure for the creation and use of fuel reserves by thermal power plants provides as an option the use of liquefied natural gas (LNG) as a reserve and emergency fuel. Replacing RF (reserve fuel) with natural gas will, to some extent, reduce the load on the environment and reduce the area occupied by reserve fuel facilities (RFF). Since the construction and maintenance of RFFs at boiler plants and thermal power plants (TPP) requires significant capital investments and operating costs, the transition to LNG, which has its own specifics, requires additional analysis, given in this article, which evaluates the requirements for LNG volumes, places of production, storage and delivery of LNG to the TPP. The potential benefits of RF's transition to LNG have been assessed and challenges requiring further research have been formulated.
