The required power reserves may run out in early December. Until the end of the year, the difference between the available power and the required power level will be satisfactory only in weekends and holidays – such are the conclusions from a balance for this and the coming months presented by the supply system operator.
The figures presented by PSE are alarming. In January – statistically the coldest month of the year – our reserves will be negative. The next months do not look any better. In February and March, the difference between the actual and the required power surplus will only be a little over 130 and 80 MW respectively.
To address the crisis – besides the already functioning operational power reserve – a mechanism called a cold intervention reserve. It involves switching on the blocks of the Siersza and Stalowa Wola power plants (Tauron), as well as the Dolna Odra Power Plant System (PGE) with a total capacity of 830 MW.
The problem is that in crisis situations these blocks will not ensure the stability of the system. Firstly, because it takes hours to switch them back on. Secondly, their technical condition leaves much to be desired. They form a part of the reserve because they cannot be working regularly owing to environmental restrictions. – They are thermal power plants, so it will not be possible to switch them quickly enough – confirms Leszek Juchniewicz PhD, former chairman of the Energy regulation Office (URE), now adviser to the President of Employers of Poland. At the same time, he emphasizes that the idea of a reserve is that ideally it would not have to be used.
