About Core CCR

The energy transition towards a carbon free electricity supply is a European challenge that requires the use of the European electricity system to the full extend. Weather-dependent supply and increasing demand response will lead to a different and more intense use of the grid. Within the Core CCR, parties involved are aiming to create operational preconditions to optimise the use of the system from a regional perspective and make the single European market a reality.

Core Capacity Calculation Region

The Core market integration project is aiming to create operational preconditions to optimise the use of the electricity system within the region. To allow Market participants to trade in different market time frames and ensure physical delivery in real time. Relevant market time frames are: forward, day ahead, intra-day and balancing. Core Transmission System Operators (TSOs) and Nominated Electricity Market Operators (NEMOs) facilitate market integration by developing methodologies and algorithms for each time frame.

The Core CCR consists of the bidding zone borders between the following EU Member States’ bidding zones: Austria, Belgium, Croatia, the Czech Republic, France, Germany, Hungary, Luxemburg, the Netherlands, Poland, Romania, Slovakia and Slovenia. These countries are in the heart of Europe which is why the Core CCR programme has a substantial importance for the further European market integration.
