Ancillary services markets

Definition

Ancillary services markets refer to the platforms and mechanisms that support the stability and reliability of the power grid by providing additional services that complement the main electricity supply. These markets enable the provision of essential services like frequency regulation, voltage control, and reserve power, ensuring that the energy system can respond dynamically to fluctuations in demand and supply. The integration of these markets is crucial for enhancing grid resilience, especially as more renewable energy sources are incorporated into the energy mix.
