Polskie Elektrownie Jądrowe

'''Polskie Elektrownie Jądrowe sp. z o.o. (abbreviated PEJ''') is a developer of nuclear power plants in Poland. It is a special purpose vehicle 100% owned by the State Treasury. The company is specifically charged with developing 6 to 9GWe of proven, large-scale, Generation III(+) pressurized water reactors such as the AP1000, APR-1400, and EPR.

Until March 2021, the functions of PEJ were a part of the PGE Group (Polska Grupa Energetyczna).

Proposed Nuclear Power Plant at Lubiatowo-Kopalino site
On December 22, 2021, PEJ announced the preferred location for Poland's first commercial nuclear power plant as the Baltic Sea coastal commune of Choczewo in Wejherowo County, Pomeranian Voivodeship at a site called Lubiatowo-Kopalino.

The siting investigation conducted by PGE and PEJ included screening 92 potential locations before detailed studies were conducted two final candidate sties. Two sites in Pomorskie – Żarnowiec and Lubiatowo-Kopalino – were subject to more detailed scrutiny and the results published in the Environmental Impact Assessment (EIA) Report submitted to the General Director for Environmental Protection on March 29, 2022. The EIA considered multiple reactors generating up to 3,750MWe at the site. On August 22, 2023 PEJ submitted an application to the Head of Pomorskie Voivodeship for issuing a location decision for Poland’s first nuclear power plant, to be built in Pomerania, in Choczewo commune – it is one the key milestones in the administrative process leading to the start of construction of a nuclear facility.

In November 2022, the Polish government selected the Westinghouse AP1000 reactor design for the proposed nuclear power station. In October 2023, the Pomeranian Voivodeship regional authority authorised preparatory work at the site; a construction permit would still be required later.

Proposed Inland Nuclear Power Plant
A second nuclear power plant at an inland location is being explored to follow the proposed first nuclear power plant on the Baltic Sea coast.
