The reactive power provider must:
- Be capable of supplying their rated power output (MW) at any point between the limits 0.85 power factor lagging and 0.95 power factor leading at the BMU terminals.
- Have the short circuit ratio of the BMU less than 0.5.
- Keep the reactive power output under steady state conditions fully available within the voltage range ±5% at 400kV, 275kV, 132kV and lower voltages
- Have a continuously acting automatic excitation control system to provide constant terminal voltage control of the BMU without instability over the entire operating range of the BMU.
This is a mandatory service for Large Generators and therefore there is no applicable Assessment Process for this service.
