A frequency ancillary service is a service that maintains the stability and security of supply in the power system. Ancillary services ensure a balance where:
-
The amount of electricity produced matches the amount of electricity demanded exactly.
-
The grid continuously maintains a frequency of 50 Hz, which indicates that the system is in balance.
With XOLTA’s largest battery systems, you can help balance the electricity grid. In this setup, you are paid both for being available and for either delivering power to the grid or absorbing power from it.
