The Polish Power Grid Company Polskie Sieci Elektroenergetyczne (PSE) was created in August 1990 by the Polish Ministry of Trade and Industry as a joint-stock company, wholly-owned by the Polish state treasury. PSE is the owner of Poland's high voltage electricity grid and is responsible for grid operations and power dispatching. The distribution subsector consists of 33 distribution companies, all of which are joint-stock companies, and utilizes 110 kV, 15 kV, and 0.4 kV lines to supply electricity to customers. Distribution companies represent approximately 40% of all Polish electricity sector assets.

Once part of the POKOJ power distribution system (the former power distribution system of the Ukraine and Eastern European countries), CENTREL (the new power distribution system of Poland, the Czech Republic, Slovakia, and Hungary) is now fully integrated into the Western European UCPTE system. Poland also maintains very strong links with distribution systems in the Ukraine and Belarus. These links provide Poland with an exchange potential with Western Europe and these former Soviet Union states on the order of 3,000 MWe per system.

As of the year 2000, the Polish power grid consists of about 200 kilometers of 750 kilovolt (kV) lines, about 4,700 kilometers of 400 kV lines, and about 7,900 kilometers of 220 kV lines, and is interconnected using more than 80 large substations.
