H-25 Gas Turbine

Hitachi’s H-25 combustion turbine is the most efficient and reliable heavy-duty gas turbine in the 30 MW unit capacity range. It is suitable to be installed in new, highly efficient simple cycle plants, cogeneration plants and combined cycle. Moreover, it is a perfect choice to replace existing General Electric MS5001 combustion turbine generators as it is designed such that the existing MS5001 foundations, buildings and ancillaries can be re-used. In addition, the H-25 will result in a 20% reduction in fuel consumption as compared to the MS5001.

The H-15 is a scaled down model of the H-25 gas turbine.
