GE - Model 7F-5 - Gas Turbine
From Gas Turbine
As part of the FlexEfficiency* 60 Portfolio of products, GE’s 7F-5 gas turbine incorporates advanced combustion technology to deliver operating flexibility, including better turndown capability, while sustaining higher levels of efficiency. This translates into increased revenue across a wide range of operating conditions.
Accelerating Turbine Advancements
The 7F-5 gas turbine’s fast start capability provides flexibility and grid support in high renewable regions. Enabling greater than 59% combined cycle efficiency, the 7F-5 gas turbine can start quickly, ramp up or reduce power output in response to wide grid fluctuations, and turn down to very low output levels, creating an unprecedented level of operational flexibility and efficiency built for modern energy systems.
