ZSE Elektrárne, s.r.o.

ZSE Elektrárne, s.r.o., operates the combined cycle power plant near Malženice in the west of Slovakia and currently, it is the biggest combined cycle power plant in Slovakia. Technically, it is based on a joint shaft connecting a gas turbine with 284 MW of capacity and a steam turbine with 152 MW of capacity, jointly totalling 430 MW, which is similar to the output of a block of nuclear power plant. 

The power plant was put into operation in 2010 and in 2013 it was put out of operation due to unfavourable conditions on energy markets. Since august 2018 the power plant is fully owned by Západoslovenská energetika, a.s. and was put into operation again. The current wide-European trend of being environmentally friendly to electricity production fits the requirement  for sustainable economical operation in the future. Technical availability of the power plant under ACER requirements is reported at the certified platform REMITOR.

The power plant incinerates natural gas and with its average efficiency of 52.3% is among the most modern sources in the Slovak Republic. Thanks to its low CO2 emission factor, it is one of the most environment-friendly sources of conventional thermal power plants. The power plant produces and supplies electricity to the Slovak distribution system through the substation Križovany and provides supporting services to Slovenská elektrizačná prenosová sústava, a.s.    This location is a strategic transit and distribution node in Slovakia, where the power plant can contribute to the energy system restoration (black start) - thanks to its energy self-sufficiency from diesel aggregates situated directly on the site. Considering its technical parameters and regulation capabilities, the power plant Malženice is a significant producer of electricity in Slovakia.
