The Polenergia Group’s Elektrociepłownia Nowa Sarzyna is located at the north-western edge of the town of Nowa Sarzyna. NSCP occupies an area of approximately 6 ha. The facility is located in an industrial area, in the direct vicinity of CIECH Sarzyna S.A. chemical plants. (CIECH Group) and Sarzyna Chemical Sp. z o.o. (Lerg Group).
The project of construction and financing of investments in the project-finance formula was developed and supervised by the first owner of the Company, i.e. by the American corporation Enron (Houston, Texas). The construction of ENS started in mid-1998, and the CHP plant started its commercial operation on June 1, 2000. In 1997, ENS concluded a long-term electricity sales agreement with Polskie Sieci Elektroenergetyczne (PSE), and in 1998 it concluded a 20-year heat supply agreement with the nearby Organika-Sarzyna Chemical Plant. Additionally, since 2000, ENS has been selling heat to the inhabitants of Nowa Sarzyna. For twenty years, gas was supplied by Polskie Górnictwo Naftowe i Gazownictwo, Commercial Branch in Warsaw, under a purchase and sale agreement of high-methane natural gas, and from 2020 it was supplied by a Polenergia Group company (Polenergia Obrót SA).
In 2011, ENS was acquired by Kulczyk Investment. Currently, the company is part of the Polenergia S.A. Group. based in Warsaw. From 2020, ENS sells electricity to a trading company belonging to the Polenergia Group. Heat is still sold to neighboring chemical plants and to the local municipal plant. The company also provides a self-start and power system reconstruction service on the basis of a renewed three-year contract with Polskie Sieci Elektroenergetyczne (mid 2020 – mid 2023).
The service covers the self-start of gas turbine sets and their operation in a separate part of the PPS to the extent necessary for the correct course of the process of restoring the operation of the National Power System after a voltage failure in the PPS or in its part. The most important element of this process is the supply of energy from the ENS for commissioning the power unit in the selected system power plant.
ENS is the first thermal power plant in Poland, the generating units of which have the ability to self-start and can be used in the process of rebuilding the Polish Power System. Until now, only hydroelectric power plants had such technical possibilities.
In 2022, ENS obtained a certificate of a participant in the Capacity Market and contracted the capacity obligation for 2027.
