This 2017 list includes 173 projects, of which 110 are electricity and smart grid projects. These projects will allow for the integration of renewable energy and its transmission over long distances. They will also strengthen security of supply through increased grid resilience and flexibility, and will allow for potential implementation of demand responseInterconnections form the hardware of the electricity system; they further the security of electricity supply, a well-functioning internal market for greater competitiveness, and, thanks to the integration of increasing amounts of renewable energy, sustainability.
The main tool for reaching the interconnection targets is through the implementation of PCIs. All these projects benefit from accelerated licensing procedures, improved regulatory conditions, and, in some instances, have access to financial support. Whenever new projects are being developed to achieve the target, the final decision for new infrastructure should always be based on a thorough cost-benefit analysis. Only those interconnectors which can demonstrate their potential benefits to be outweighing the costs should be developed.
