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, emissions-compliant peak-fire without ambient temperature restriction, up to max equipment capability.

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).

Enables extended combined-cycle plant load turndown by operating the steam turbine outside of inlet pressure control (IPC) at as low a load as possible while maintaining forward HP flow and bypassing excess steam flow to the condenser. Potentially up to 5-10% reduction in minimum combined-cycle load possible.
