RETE-TRA 2016 - Evolution and development of the power transmission network

The present report deals with issues related to the selection of power transmission grid infrastructures in Europe as well as to the background approach and methodology for the calculation of interconnection capacity targets set by the European Commission.

The present report deals with issues related to the development and selection of power transmission grid infrastructures in Europe as well as to the methodology for the calculation of interconnection capacity targets set by the European Commission (EC). These topics are strictly correlated: focus is in particular on European PCIs (Projects of Common Interest), whose realisation is crucial to achieve the European Union (EU) energy and climate policy targets for 2020, 2030 and beyond towards the build-up of the Energy Union.

The report firstly recalls the EU framework related to the development of strategic power grid infrastructures in Europe and PCIs in particular. Then, focus is on the issues related to the interconnection capacity targets set by the EC at 10% for 2020 and at 15% for 2030 for each EU Member State. The ratio that forms the interconnection capacity target for a country can be calculated dividing the total net import capacity, that is based on the concept of NTC (Net Transfer Capacity) in import, at each cross-border corridor - in the numerator of the ratio - by the total NGC (Net Generating Capacity) of the country - in the denominator of the ratio - for each EU Member State.

Particular attention is paid to the interconnection capacity targets calculation methodology: remarks and suggestions are highlighted on how to deal with the consideration of NTC in import and of NGC for each EU country.

Concerning the calculation of NTC in import, clear geographical and political indications shall be provided by the EC in order to establish which corridors with which bordering countries have to be included in the total net import capacity for each EU Member State.

Concerning the calculation of NGC, key issues related to the inclusion of variable RES (Renewable Energy Source) capacity shall be treated by the EC. In fact, without a clarification on how to include variable RES capacity together with more conventional - thermal, hydroelectric - generation in total NGC for each EU country, the ratio for the interconnection capacity target calculation could assume rather moderate or even low values in the mid-to-long term with boosting variable RES penetration in more EU countries.

In the described context, various options and available measures for the proper interpretation and calculation of NGC and NTC in the EU are critically discussed; also, starting from current situation, proposals for the interconnection capacity targets setting with the related implication of PCIs are presented, taking stock of the European GridTech project analyses carried out by RSE for 2020, 2030 and beyond 2030.

In addition, some crucial elements in terms of methodological findings and outcomes obtained by RSE in the frame of the European GridTech project related to PCI selection and expansion planning for future European transmission system are highlighted.

The report contains different recommendations on the topics treated.
