Environmental implications of the use of electric heat generators for the compaction of electrical load schedules during the night depressions of the UES of Ukraine
Journal Title: Проблеми загальної енергетики - Year 2018, Vol 0, Issue 4
Abstract
This article presents the results of our analysis of the environmental implications of using different types of consumer regulators (electric boilers, heat pumps and cogeneration units), intended to regulate the load of the UES of Ukraine during its «night depressions». It is established that additional electricity consumption by electric heat generators (EHG) will be equal to 5.35 billion kWh per year. For the production of this amount of electricity, it will be necessary to burn from 6527 to 7456 thousand tons of coal at TPPs (depending on the period of operation of EHG), which will have a significant influence on the environment in the form of emissions of greenhouse gases and pollutants, namely sulfur oxides and dust. As follows from here, in accordance with the Tax Code of Ukraine, TPPs will be forced to pay additional taxes on these emissions, which will reach about 200 million UAH per year before their reconstruction. Therefore, the introduction of electric heat generators is expedient after the modernization and reconstruction of thermal power plants, which will significantly reduce the emissions of harmful substances and, accordingly, taxes on them by a factor of 13.8. If heat pumps are used as electric heat generators, a significant area of the soil will be cooled during the life cycle of their operation, which will make it unsuitable for planting, disturb the ecological balance, and cause discomfort to the inhabitants. The process of soil temperature restoration after the removal of heat pumps from operation will take more than 20 years. In the case of introducing high-power air heat pumps, there is a risk of changing the microclimate of a residential area (overcooling during the cold season and overheating in summer). To reduce the influence of heat pumps on the environment, it is expedient to use low-potential energy sources of anthropogenic nature, namely, the heat of sewage, technological water, ventilation systems, flue gases, and others.
