Insight into Day-Ahead Contracts

CLC / CSC Activations

On this page, we publish the monthly activations of CBC and CSC contracts per area. This data provides insight into the volume and location of day-ahead congestion issues.

Monthly CBC / CSC Activations

This overview contains all CLC and CSC activations for the period from 1 to 27 May. For each activation, the activation date, the location (substation/congestion area), and the activated volume in MWh are displayed. The map visualizes this data spatially:

  • Orange dots indicate the locations where grid operators have concluded day-ahead capacity contracts.
  • Blue areas show where and to what extent these contracts were activated during the previous month.

The combination of the Excel overview and the map provides insight into both the distribution of concluded contracts and their actual utilization (activations).

Frequently Asked Questions

Can I see GOPACS call-off data regarding price and volume on location level?

No. Due to privacy reasons, this is not possible. On our website, we only publish information that complies with the legal transparency requirements set out in the Grid Code (Netcode) and ENTSO-E regulations.

Can grid operators predict where flexible capacity is needed?

Grid operators are increasingly able to estimate where and when the electricity grid may come under pressure, based on real-time grid data and forecasts. However, a congestion situation cannot always be predicted down to the exact quarter hour. It depends on factors such as electricity production, consumption, and weather conditions.

When grid operators expect congestion, they deploy flexibility in a targeted way. This can be done in several ways:

  • Redispatch (intraday)
    When grid overload is expected or emerging, grid operators ask the market for bids through GOPACS. A market message indicates in which area and at what time flexibility is needed. GOPACS then helps select the most effective bids, while ensuring that the solution does not create new bottlenecks elsewhere on the grid.
  • Capacity Limitation Contracts (CLCs)
    With CLCs, flexibility is arranged in advance. With CLC-T, fixed time windows are agreed in which flexibility is delivered (predictable). With CLC-A, you are only called upon when flexibility is truly needed, and you are notified at least one day in advance (day-ahead). In both cases, these contracts help grid operators manage expected pressure on the grid in a controlled way.

In short, grid operators can often identify the main risk areas and moments, but they combine real-time insights with different instruments — such as redispatch and CLCs — to activate flexibility at the right place and time.

Where can I see which areas are requesting bids?

On this page you will find the congestion areas for which grid operators are making or have made a call for proposals.

What compensation can I expect for participating in congestion management via GOPACS?

This depends on the flexibility product you choose. When participating through redispatch, you receive compensation based on market prices for the flexibility you provide. With contract types such as a Capacity Limiting Contract (CLC) or a Mandatory Bidding Contract, fixed availability payments or control payments may also apply. The exact compensation structure depends on the grid operator and the specific contract.
