In the analysis of electricity imports to our country, Polish Power Grids indicates that so far generation from renewable sources has not translated into a particular increase in the number of shutdowns and commissioning of conventional power plants. However, they emphasize that the needs of the system in this regard will increase with the increasing importance of weather-dependent sources.
According to PPG, although historically Poland was an exporter of electricity, it is currently an importer. The main reason for this is the increase in the cost of CO2 emissions, which increases the production costs of coal-fired power plants. As assessed by Polish Power Grids, in 2020 commercial net energy import to Poland may amount to approx. 13 TWh. They also emphasize the growing share of imported energy, but note that this is not the only important factor that affects the operation of domestic conventional thermal power plants.
