Application of innovative grid-impacting technologies in pan-European andregional case studies towards the EU Energy Union: the GridTech analyses

L’articolo presenta i risultati principali dello studio pan-europeo e degli studi regionali irlandese e italiano di GridTech al 2030 e al 2050.

The achievement of ambitious decarbonisation targets set for 2020, 2030 and beyond by the European Union (EU) will require extensive electricity system planning and investments. In particular, the development of adequate transmission infrastructures and grid-impacting technologies plays more and more a crucial role to foster the integration of Renewable Energy Sources (RES) and to realize the European Energy Union, set as strategic target by the European Commission. In this framework, the main objective of the GridTech project has been to conduct an integrated assessment of new grid-impacting technologies and their implementation into the European power system, comparing different technological options towards full RES exploitation, with the lowest possible total electricity cost.

For the purpose of GridTech project, the focus is on the innovative technologies that may (directly or indirectly) impact on the transmission grid development and operation and support the integration of variable RES. These elements are grouped in Transmission Grid Technologies (TGT), Energy Storage Technologies (EST), Electricity Demand Technologies (EDT). The approach of the project entails the analysis of the 2020, 2030 and 2050 time horizons, to assess which innovative technologies and where, when, and to which extent they could effectively contribute to the further development of the European transmission grid, also towards potential supergrid architectures. For each target year and scenario, the methodology is based on the evaluation of the different benefits to the European power system provided by the innovative technologies comparing the case implementing the assessed technology with respect to a base case without it.

The techno-economic assessment of the different options is completed by technology cost calculation and is carried out at two correlated levels by a pan-European approach analysis (top-down) and by regional case studies (bottom-up).The present paper, after investigating the approach adopted within GridTech, focuses on main results of the pan-European study as well as of the Irish and Italian regional analyses, with particular attention on 2030 and 2050 scenarios developments.
