Survey: European Renewables Capacities Not Connected to the Grid

Renewables are crucial to overcome the energy crisis and to achieve European climate and energy targets. Grid connectivity brings general societal benefits, such as improved flexibility and reliability, and reduced electricity costs. To determine the available RES capacities non-connected to the grid throughout Europe, as well as the reasons for lack of grid connectivity, RGI is launching a survey to be completed by July 2023.

Implementing the energy transition and addressing the current energy crisis requires capacities in renewables generation.

Related to this, the need for development and improvement on the electricity grid infrastructure has been highlighted as one of the main bottlenecks to make European climate and energy targets possible. 

Investigating lack of connectivity

Grid connectivity also allows for improved flexibility and reliability, as well as reduced electricity prices, bringing benefits both to the energy sector and consumers in general. Considering these benefits, a question comes to mind: why are there projects on renewable energy sources (RES) disconnected from the grid? 

To better understand which RES projects are not connected to the grid and the reasons behind the lack of connectivity, we launched the survey "European renewables capacities not connected to the grid", aimed at identifying:

  • which renewable energy (RES) projects (mainly wind and solar) are already built, but not yet grid connected;
  • which RES projects are expected to be completed and ready to be connected within the coming 6 to 12 months across Europe (counting from the time when this survey is completed);
  • and the reasons for lack of grid connectivity.


How and why to fill out the survey?

We welcome inputs from different stakeholders within the energy sector. The obtained results will be discussed with ENTSO-E and selected TSOs, leading to recommendations on how to overcome bottlenecks to be drafted, published, and shared with respondents and policy makers.

Raw data will remain confidential and will not be distributed to third parties, unless specific permission is granted in writing. Please, download the survey and submit your answers by 31 July 2023 via email to our Manager - Energy Systems, Damiano Ottavi.

 If you are not able to provide all information requested, please type "N/A". Also, it is important to fill the "Respondent information" box if you would like to be informed about the final results.

In case you have any questions, please feel free to contact
