Alstom Grid has signed two contracts, each worth approximately €5 million, with Eltel Networks Rzeszów S.A. for the delivery of 110 kV and 220 kV gas-insulated switchgear (GIS) in Poland. The equipment is destined for the Kopanina project, owned by PSE S.A. - the main provider of electricity transmission services for the Polish power system. Commissioning of the 220 kV gas-insulated switchgear is planned for summer 2014 and the 110 kV substation, for spring 2015.
The Kopanina substations are the ‘access point’ for generator units of the Łaziska Power Plant (owned by Tauron Wytwarzanie S.A. Group) and a key supply point for the Silesia region, south-east Poland. The projects are part of €2.4 billion (9.9 billion PLN) Polish Power Grid investment programme aimed at increasing the safety and reliability of electrical energy transmission across the country. As part of the plan, PSE aims to construct a 10,400 kV transmission line, four 220 kV transmission lines, ten substations, and expand 39 power stations.
Alstom Grid will manage the delivery and supervision of erection and commissioning of the 110 kV and 220 kV gas-insulated switchgear, including local control cubicles (LCC). The 220 kV GIS includes a double-busbar and two switchgear sections with ten circuit breakers bays. It is equipped with a maintenance insulating device (MID), which ensures, in case of failure in one of the bays, continuous operation of the remaining bays. The 110 kV F35 substation includes 17 gas-insulated bays with 3-BB (busbars). It is the third 110 kV F35 gas-insulated substation with 3-BB (busbars) delivered by Alstom Grid in Poland.
“This is the fifth 220 kV gas-insulated switchgear and third 110 kV substation delivered by Alstom to PSE S.A in Poland. The award enhances Alstom’s market position as the premier supplier of high voltage gas-insulated substations,” said Michał Golasz, Managing Director of Alstom Grid in Poland.
All of the switchgear equipment will be manufactured in France, Switzerland and Poland.

 A busbar conducts electricity within a substation. The cross-sectional size of the busbar determines the maximum amount of current that can be safely carried.
