PRESS RELEASE

PRYSMIAN AWARDED €60 M CONTRACT AS PART OF LIGHTNING PROJECT IN UAE

SCOPE OF WORK: LAYING 134 KM ROUTE OF DC SUBMARINE CABLE SYSTEM

Milan, 14 November 2022 - Prysmian Group, world leader in the energy and telecom cable systems industry, awarded a €60 million contract for laying submarine cables for the already secured Project Lighting HVDC 320 kV interconnection project in the UAE (awarded to Prysmian under a limited notice to proceed last January 2022 by Samsung C&T as part of its EPC consortium with Jan De Nul Group, the initial contract was worth €220 million). Abu Dhabi National Oil Company (ADNOC) and Abu Dhabi National Energy Company PJSC (TAQA) announced the successful financial closing of their $3.8 billion strategic project to power and significantly decarbonize ADNOC's offshore production operations on September 23, 2022.

Main purpose of this new HVDC link is to replace the ADNOC's current offshore power by a green onshore power source, reducing its environmental impact and CO2 emissions, in addition to supporting its objective to decarbonise its offshore production operations.

Offshore installation operations will be performed by the Group's cutting-edge DP cable-laying vessel Leonardo da Vinci, with the shallow water activities being performed by the Group's advanced cable-laying barge Ulisse. The state-of-the-art Leonardo da Vinci vessel will ensure time efficiency and CO2 emission reduction, further confirming the Company's ability to execute complex and complete installation projects.

Under the ADNOC Lightning Project, Prysmian will design, supply, assemble and test a symmetrical monopole system consisting of four HVDC 320 kV single-core cables with XLPE insulation, along with fiber optic cable systems, that will connect the Al Mirfa onshore converter station to Al Ghallan, an artificial offshore island in the Arabian Gulf, located off the Abu Dhabi coast, in the United Arab Emirates. The project comprises both a subsea route of approximately 134 km of submarine HVDC cables, and onshore routes located at Al Mirfa and Al Ghallan Island totalling approximately 3.5 km of HVDC land cable route. The commissioning of the project is scheduled for 2025.
