PSE AND THE ENVIRONMENTPSE's role in the power sector

Polskie Sieci Elektroenergetyczne manages the operation of the entire National Power System. For years, we have been ensuring the smooth operation of this system, which consists of units that generate, process, transmit and distribute energy. Thus, we ensure continuity of energy supply and its public availability.

Our organisation feels responsible for the proper functioning of the Polish economy and domestic companies. In view of recent developments, including those relating to the geopolitical situation, power and energy security is a priority for us.

How does the power system work?

The National Power System (NPS) is made of three subsystems responsible for specific tasks.

– Electricity generation – the production of electricity by generation sources, which – in the power system – are power plants, combined heat and power plants and distributed sources.

– Electricity transmission – is carried out by the transmission system operator whose functions are performed by PSE through the transmission network in order to supply energy to distribution networks or to consumers connected to the transmission network.

– Electricity distribution – is carried out by distribution system operators, and consists in the supply of energy through distribution networks to institutional and individual consumers connected to the network.

Worth knowing
  • The national transmission network is supplied with AC voltage at 50 Hz.
  • In Poland, the following voltage standards are most commonly used to transmit electricity:
  • The extra high voltage levels most commonly used in Europe are: 220–275, 300–330 and 500 kV.
