Poland’s 400 kV Pila Krzewina–Plewiska line passes voltage tests [free access]

May 27, 2021

Poland’s transmission system operator (TSO) Polskie Sieci Elektroenergetyczne SA (PSE) has announced that the 400 kV, 92-km-long Piła Krzewina–Plewiska line is ready for electricity transmission.


The project is part of PSE’s PLN1.2 billion investment plan for new transmission infrastructure in Wielkopolska. The 400 kV power line has successfully passed the voltage tests and is ready for energy transmission. Currently, the line is being tested.


As reported, construction of the line took over five years and replaced well-worn infrastructure from the 1960s. A consortium of two local companies—IDS Energetyka and Enprom HVL—carried out the design and construction. The facility will be a very important element of the national power system and will ensure reliable electricity supplies to over three million customers in the Greater Poland Voivodeship (a Polish province).


For the implementation of the 400 kV line as well as the expansion and modernisation of the highest voltage stations serving it, PSE obtained over PLN208 million in funding from Poland’s Infrastructure and Environment Operational Program.
