The introduction of large-scale renewable energy projects such as solar and wind power generation has become a global trend. However, as is well known, renewable energy is very unstable, and solar power cannot be generated after sunset. This has already become a major problem, and in some regions, solar power generation has to be restricted for the stable operation of the electric grid system. To further expand the introduction of renewable energy in the future, it is essential to install thermal power sources to compensate for load fluctuations in the electric grid system. This power supply requires fast startup and ramp rate characteristics and high efficiency with lower CO2 emissions, and the aeroderivative gas turbine (Aero GT), which is most suitable for these requirements, will be introduced here.
In Japan, the market is expected to shift to full liberalization through the separation of power generation and transmission, and the capacity and adjusting capacity market as Ancillary market will be developed based on power system stabilization at the time of renewable energy introduction. The Aero GT is a promising product for this market and this paper describes the characteristics of the Aero GT and examples of its activities in Europe and the U.S.A.
