CESI Supports Terna in the Tyrrhenian Link

CESI is proud to support Terna in the implementation of the Tyrrhenian Link, the record-breaking submarine link – the longest and deepest HVDC cable ever laid – featuring 500 kV HVDC and 1000 MW per cable, linking the islands of Sardinia and Sicily to the Italian Peninsula. This internationally significant project will strengthen the Mediterranean energy hub, fostering a more sustainable energy future.

Thanks to its technical and environmental expertise, CESI is working alongside Terna throughout the entire project, from the feasibility phase to construction, and will continue to provide high-level specialized consultancy in the post-operam phase.

Our team was on board during marine surveys, contributing to cable routing and identifying the best techniques for crossing valuable habitats. As technical and environmental consultants, we have carried out preliminary planning and designing of compensation measures, including the transplantation of Posidonia oceanica and an innovative experimental transplantation of Cymodocea nodosa. We also participated in technical meetings with Terna, MASE, ISPRA, and CoNISMa (which was entrusted with implementing the transplantation activities).

To ensure the project’s environmental sustainability, we developed the Environmental Monitoring Plan for cable laying and are overseeing the construction activities of the eastern section, conducting environmental surveys and monitoring the initial campaigns.

Once again, this collaboration highlights CESI’s deep involvement in complex projects, addressing the challenges of energy transition and environmental sustainability.
