Alstom launches upgraded KA26 gas turbine, claims 61 per cent efficiency

Alstom has launched its latest upgrade to its KA26 combined-cycle gas turbine (CCGT) featuring higher efficiency of over 61 per cent with a capability of generating 350 MW in less than 15 minutes from low load.
In a statement, the French manufacturer says the KA26 also offers a higher output of more than 500 MW and lower emissions, avoiding more than 350 000 tonnes of CO2 annually.
Alstom said gains in power output and efficiency comes from an existing well-proven technology platform. The gas turbine is being offered to the market following extensive R&D and testing at Alstom’s full-scale test power plant in Birr, Switzerland.
The GT24/GT26 gas turbines were introduced in the mid 1990s and more than 60 combined cycle plants based on this turbine are currently in operation. Over 10 GW from this technology went online in 2010.
