• Global Trends







Current challenges in the grid

Higher utilization of

renewables and less

rotational inertia from

conventional power

generation units

Stability of the grid and

secure supply of power

Higher flexibility and

shorter reaction time requirements to the producers



Power producers have to broaden their capabilities

Conventional power plants (heavy duty as well as industrial scale) need:

• Accelerated load ramping for fast compensation of unbalances in the grid

• Spinning reserve as additional power reserve to stabilize the grid

• Islanding and off-grid services (especially for industrial power plants)

• Black start capability in the case of a grid failure

ensure grid stability as the power system operation is under threat
