Balancing service is an ancillary service under which the balancing market participants, following the procedures laid out in the Ancillary service agreement, increase or reduce the electricity production (capacity) in their power generation facilities or provide a demand response service.
To facilitate equal opportunities for all Baltic balancing market participants and to comply with European Commission Electricity Balancing guidelines, Baltic transmission system operators agreed to organize a common balancing market.
