OpFlex* Load Flexibility

Online user or Automatic Generation Control (AGC) adjustable peak fire for additional output, subject to user defined MW or emissions limitations. Peak maintenance factor applies.

Provides variable peak fire operation without ambient temperature restriction, up to max equipment capability, or a user-set emissions limit.  Super Peak available for even greater peak fire on F-class units with Advanced Gas Path installed.

Online user adjustable max IGV setting for better baseload output or better combined-cycle heat rate; onetime fixed adjustment possible for Mark V and VI controller, non-AutoTune configurations.

Advanced load control software to enable compliance to global grid codes and grid testing requirements, and enable participation in grid support ancillary services industries (requires ETS).

Enables improved turndown for units without IBH through the use of enhanced IGV control in warm ambient conditions where icing risk is low.

Combustion control software to extend the emissions compliant load range to 5%– 10% lower load levels.

Enables improved part load efficiency for simple cycle units by improving the GT fuel and air control logic while maintaining CO emissions compliance (requires AutoTune for B and E class).

Replaces static IBH schedule logic with actively adjusted logic to increase IBH only when needed. Improve efficiency in some situations (requires AutoTune for B and E class).
