New Plant
GT24 and GT26 Gas Turbines - Key benefits
> Competitive kilowatt hour
In combined cycle applications, the GT24/GT26 is capable of net plant efficiencies of close to 60% using already proven gas turbine technology.
> High reliability/availability
Low turbine inlet temperatures, a uniform annular temperature profile, a maintenance free, welded rotor and a simple and robust EV burner all help to reduce maintenance needs and therefore improve availability.
> High Power density
High power density design leads to smaller components. Compared to Alstom's conventional gas turbines, the GT24/GT26 provide up to
60% more output for the same footprint.
> Operational flexibility
Sequential combustion means unrivalled operational flexibility which includes the ability to handle wide fluctuations in gas compositions. An operating range, down to 40% part load and below while keeping low NOx emissions, allows the plant to meet all power demands. During periods of low electricity demand the plant can be powered at a very low combined cycle load allowing a fast re-loading when power is needed urgently. This is known as Low Power Operation concept.
> Clean Power
Sequential combustion technology is the industry’s most innovative platform for clean power generation, giving gas turbines with low
emissions and high efficiency.
> Long-term payback
In combined cycle applications, the GT24/GT26 can deliver a significantly higher internal rate of return compared to conventional turbine technology.
