How do we do it? Planning Studies

​Step 1 – Develop scenarios for the future

To identify what Europe needs in terms of electricity transmission infrastructure, one needs to first analyze how the energy landscape will evolve. Some political objectives are set until 2030 but a lot of uncertainties about generation investments, demand evolution, market developments to name a few. The TYNDP scenario development is about framing uncertainties. It is not about predicting the future. Stakeholders are strongly and formally invited to participate to the scenario building. See how you can get involved.

Step 2 – Planning Studies

The TYNDP has four scenarios for the development of the power system. Some have high objectives in terms of renewables, some envisage a more decentralized power system, and some envisage a strong European framework. Based on these scenarios, 200 experts of 41 TSOs in 34 European countries carry out common planning studies. 

Using common methodologies and tools, these experts look at how power will flow in Europe in 2030 taking into account the different scenarios. This allows them to see where bottlenecks will be and how much transmission capacity is needed at borders to manage these flows. 

The results of the planning studies is a series of infrastructure projects. These are only one part of the whole TYNDP projects. The other part is constituted of projects that are not coming from ENTSO-E members and that meet the criteria for inclusion in the TYNDP set by the European Commission. 

The projects resulting from the planning studies take into account the constraints identified in the 6 Regional Investment Plans which are published together with the list of projects. As for the scenarios, the list of projects and regional investment plans are open to public consultation before being finalized.

Step 3 – Projects assessments

The last phase of the planning process in the TYNDP is the assessment of projects. This is done using a European approved methodology to assess the costs and benefits of projects. This assessment is not just a purely economic assessment. It takes into account also how projects support the environment, the welfare in Europe, the security of supply among others. The results of this costs and benefits assessment of projects forms the core of the TYNDP report. 

​By reading the TYNDP report, everyone can see the value of each infrastructure project. The TYNDP is providing decision-makers with a robust and detailed analysis of transmission infrastructure projects on which to base their decisions. One illustration of this is the fact that TYNDP projects and their assessment is used in a European Commission-led process the Projects of Common Interests.
