The power generation mix is in transition with more and more electricity generated by renewable sources. Combined cycle power plants will have to partner with renewable sources and compensate for their fluctuating nature. In preparation for the next generation combined cycles, gas turbine technology development needs to continue to lower the lifecycle costs through increased efficiency, extended maintenance cycles, and reduced emissions. It must now also develop fast ramping capability, account for a wider variation in fuel composition and provide an emission effective part load operation. These needs will be met by refining state of the art technologies and by adding new technologies. This paper provides an overview of the research and development activities and resulting trend in Alstom gas turbine technologies.
