New 910 MW Supercritical Unit for Power Plant Jaworzno III in Poland (Room G109, Auditorium Centre, First Floor)

On 17.04.2014 has been signed Contract between TAURON Wytwarzanie S.A. and the Consortium RAFAKO S.A. (leader) – Mostostal Warszawa S.A. for the construction of full turnkey 910 MWe power unit. Construction of a new Power Unit has huge significance for the Polish power sector. The contract was signed in EPC formula. Unit 910 MWe in Jaworzno PP III will be connected to a new 400 kV switching station, deriving electricity to the National Power System. Unit net efficiency is assumed to be almost 46%. The complete scope of work should be completed within 59 months from Contract signing. Warranty period is 24 months after PAC. The most and the best available technology and the global experience in the construction and equipment of new large Power Units will be used in the investment. The new Unit will fulfill all requirements under the EU Directive concerning pollutant emissions into the atmosphere. The investment is also very important for the reconstruction of Jaworzno PP energy production capacity and also for the continued development of the region, where it will be located. Fuel for the new unit will come in nearly 80% from the mines belonging to the group TAURON. The new unit will produce annually 6,5 TWh of electricity, equivalent to 5% of the current domestic consumption of energy. New constructed Power Unit will be characterized by high, more than 94% boiler efficiency, what will help to achieve high environmental indicators. High unit efficiencies allow to reduce fuel costs and emissions. Comparison of the amount of pollutants emitted into the atmosphere attributable to the amount of electricity generated by currently operating in Tauron 120 MWe units equal to the amount of energy produced by 910 MW Unit is confirmation of obtained positive ecological effects. The article presents the main technical solutions to be applied in the field of boiler island and turbine island of new of 910 MW unit.
