The scenario building and energy system modelling are at the core of the TYNDP process. The main outcomes regarding infrastructure gaps and cost-benefit evaluation, as well as the usability and acceptance by the manifold stakeholders rely heavily on a suitable design of these features. The recast of the TEN-E regulation has strengthened the mission to reflect energy systems integration and the Energy Efficiency First principle adequately and ambitiously in this process. In view of these challenges, the TYNDP methodology is set to advance along with the state of knowledge on scenario building and energy system modelling. This document presents the STEERS methodology for improving the network planning process. We present a set of building blocks to enhance streamlined European energy infrastructure development. These are based on academic literature on scenario development and state-of-the art energy system modelling.
