The service life of new GU will increase to 40 years, new turbines will have the maximum efficiency of 96.6% and improved output and cavitation performance. The turbines will also be equipped with enhanced technological protection system. GU No.3 launched today will be in service until October 2014 when it will be replaced with new equipment.
