Since the new Grid Code of June 2022 came into force, only authorised Congestion Service Providers (CSP) can still submit bids through GOPACS. A CSP's main role is to handle local power surpluses and shortages when a grid operator expects congestion somewhere in the electricity grid. Demand then exceeds the capacity of the grid. This absorption of shortages or surpluses can be done in various ways, for instance by switching wind turbines or solar panels on or off, temporarily lowering electricity demand somewhere or by using a battery in which electricity is temporarily stored.
