The characteristics of the power plants capabilities in Poland and their sensitivity to possible failures can be carried out on the basis of several main criteria. These include: date of creation, fuel used for energy production, possessed production capacities, total contribution to the energy market, and modernization and refurbishment. In order of a comprehensive description, which will reflect both, the situation in a national scale, as well as present the specific features of the power supply system for individual voivodships, the characteristics will be based both, on aggregated data and divided into individual regional systems. Polish electrical capabilities in 2016 In the scope of the production capabilities of the Polish energy system, according to the Energy Regulatory Office (ERO), the volume of gross domestic electricity production in 2017 stood at a higher level than in the previous year and amounted to 165 852 GWh (increase by 1.98%). In the same period, the gross domestic electricity consumption had level of 168 139 GWh and increased almost 2.13% compared to 2016. The rate of growth of domestic electricity consumption was lower than the GDP growth in 2017, which according to preliminary estimates of the Central Statistical Office gained 4.6%. The installed capacity in the National Power System (NPS) amounted to 43 421 MW, and the capacity of 43 332 MW. It is an increase of 4.9% and 5% in relation to 2016. The average annual power demand was 22 979.7 MW, with a maximum demand of 26 230.6 MW, which means respectively an increase of 2.2% and 2.7% compared to 2016 [1]. It is worth mentioning that the highest power demand in the history of the NPS occurred on 28.02.2018 at 18:30 and was equal 26 448 MW, while the lowest energy consumption in 2018 was recorded on 24.06 at 4:45, being equal 12 211 MW [2]. It is worth mentioning that the reduction of the network loss rate in transmission and distribution of energy[...]
