In the past, GTCC primarily operated as the main power source for base-load operations, however with the rise of renewable energy GTCC must now support wide-ranging modes of operation including increased numbers of startup and shutdown, low-load operation and increased load fluctuations. In this environment, it is increasingly essential to maximize capacity value (revenue from capacity payments), in addition to actual power generation to maximize asset profitability by operating plants more flexibly. To achieve this, we are now better prepared than ever to extend maintenance intervals using a highly precise and reliable method, which involves compiling and analyzing operational data in real-time to maximize GTCC asset value. This solution is supported by more than 20 years of know-how of remote monitoring technologies at the Mitsubishi Power TOMONI HUB.

We can also increase revenue from electricity sales by avoiding planned inspections in the summer and winter when electricity prices are high.

Improving availability by optimizing maintenance intervals increases revenue from electricity sales in wholesale market, but it also delivers a higher asset value for the GTCC on the capacity market, which has been increasing in recent years. As a result, we can adapt to the new values required of GTCC as decarbonization moves forward.
