Every two years, the European Network of Transmission System Operators for Electricity (ENTSO-E) and for Gas (ENTSOG) must prepare joint scenarios which set the basis for the future network development planning in the European Union.
Scenarios include a set of assumptions about energy demand and supply evolutions that are used in the biennial Union-wide ten-year network development plans (TYNDPs) for electricity and for gas. These TYNDP processes feed into the identification and selection of projects of common interest (PCIs), which play an important role in making the infrastructure ready to achieve the Union’s energy and climate policy objectives.
Given the importance of the TYNDP scenarios, the recast TEN-E Regulation stipulates a more structured process for developing the joint TYNDP scenarios. As part of this process, the preparation of the joint TYNDP scenarios must follow new Framework Guidelines developed by ACER.
ACER’s Framework Guidelines aim to ensure the TYNDP scenarios are transparent, non-discriminatory and robust, as well as in line with the Union’s climate and energy policies.
ENTSO-E and ENTSOG shall follow ACER’s Framework Guidelines when they construct the joint TYNDP scenarios. ACER shall update these Guidelines regularly, as necessary.
