Our company, as the only TSO in Poland, is responsible for maintaining quality parameters in the NPS, enabling the supply of electricity to consumers connected to the NPS and interconnection exchange. It is also responsible for the transmission of electricity through the transmission grid and cross-border interconnections, which translates into PSE's responsibility for the transmission infrastructure, including the performance of operation, maintenance and overhaul work, as well as modernization projects and work to extend the grid.
The transmission grid must address changes resulting from, i.a., an increase in the demand and the structure of electricity consumption in the country, as well as changes in the structure and location of generating sources, including RES, but also from the developing cross-border exchange.
Maintaining the required quality parameters of the supplied electricity and ensuring the safety of the NPS operation involves the need to purchase system services provided by electricity producers.
