Alstom has won the contract to retrofit the low-pressure steam turbines together with a new generator at Unit 1. The company will supply eight low-pressure steam turbine inner blocks.
Designed to enable high availability with long service cycles, the efficiency of the power plant will be increased by about 1% as a result of the project, increasing electrical output of both units by about 25 MW.
Alstom’s Swedish subsidiary is responsible for the contract, which includes - in addition to the retrofit of the low-pressure turbines - the new generator for Unit 1, the corresponding generator for Unit 2 ordered earlier, and all required design and installation. The value of the contract totals about €100 million.
The installation will be carried out during the 2010 and 2011 annual service outages.
The announcement follows a short shutdown of Unit 2 at the plant as a result of a fire on a turbine bearing. The fire was caused by the heating of oily insulation material on the turbine. The oily insulation material has now been replaced with clean insulation.
