The 70% target

​Maximising cross-zonal trading opportunities is a core element to ensure an efficient internal electricity market. It is also important for meeting a number of future challenges in Europe's energy trajectory, including the decarbonisation targets.

The Clean Energy Package offers a new opportunity to increase the capacity offered for cross-zonal trade. In particular, Transmission System Operators are required to ensure that at least 70% of the transmission capacity is offered for cross-zonal trade, while respecting operational security limits. ​

What's the role of ACER?

​The 70% target has become a key element of market integration, which requires intensive monitoring. To ensure a harmonised approach on how to monitor the achievement of the minimum level of available cross-zonal capacity (MACZT), ACER will monitor the MACZT in relation to the 70% target.

The results will be regularly published in dedicated reports.
