2. ENERGY DEMAND MANAGEMENT On 10th August 2015, when the 20th level of electric power supply limitations was introduced for the first time since 1980s, it turned out again that the energy sector required changes that would guarantee the certainty of energy supplies at competitive prices. The growing dilemma of how to finance the reconstruction of generation capacity in electrical power engineering could be partly mitigated as a result of undertaking actions on the part of energy demand management. The development of energy storage through car batteries and energy warehouses located at the charging facilities for electric 2) vehicles, related to electromobility, will allow to treat infrastructure of electric vehicles in the future as energy reserves which provide energy at the moment of peak demand and charge during the so-called 'night low power demand. From the point of view of energy generation, the development of electromobility will be an additional element enabling to optimize the operation of the National Power System during the peak demand period, 3) and therefore, it constitutes a saving which consists in the lack of necessity to maintain a part of generation capacity that is unprofitable due to the fact that it is only operated for several hundred hours per year. Achievement of the number of 1 million electric cars in Poland by 2025 will result in generating additional energy demand at the level of 4.3 KWh per year, which will provide the sector with additional PLN 20 million from energy sales (assuming the average Achievement of the number of 1 million electric cars in Poland by 2025 will result in generating additional energy demand at the level of 4.3 KWh per year, which will provide the sector with additional PLN 20 million from energy sales (assuming the average expected lifetime of a car at the level of 10 years). The funds obtained in this manner may be partly used for financing innovations in the energy sector in order to gradually reduce the carbon footprint of energy produced in Poland.
