Abu Dhabi National Oil Company (ADNOC) and Abu Dhabi National Energy Company (TAQA) are executing the region’s first high-voltage, direct current (HVDC) sub-sea transmission system project, that will connect ADNOC’s offshore production facilities to EWEC's onshore electricity grid using state-of-the-art technology.

The planned project is first subsea power transmission network in the Middle East and could reduce Adnoc’s offshore facilities carbon footprint by up to 30 percent through Taqa’s onshore power production.

The transmission system will connect to EWEC’s onshore electricity grid, operated by its subsidiary, Abu Dhabi Transmission and Despatch Company (TRANSCO) and provide a total installed capacity of 3,200 megawatts.

The project will be funded through a special purpose vehicle jointly owned by Adnoc (30 percent), Taqa (30 percent) and the selected developers and investors (40 percent) and the successful bidders, alongside Adnoc and Taqa, will develop and operate the transmission system, with the full project being transferred to Adnoc at the end of the transmission agreement.

The first cable cluster, connecting Das Island to shore, comprises three 400-kilovolt (kV) subsea cables of 135 kilometers (km) each. The second cluster, connecting Al Ghallan island to shore, concerns four 320 kV submarine cables of 125 km each.

The project is known as "Project Lightning” and is aimed at using excess electricity capacity from the Barakah Nuclear Power Plant to power ADNOC’s offshore assets.

The US$3,600 million project includes the following:

1. Laying of a 900km 320/400kV XLPE HVDC Submarine cable-based subsea transmission line with a maximum of 600MW power capacity

2. Laying of a 900km 320/400kV XLPE HVDC Submarine cable-based subsea transmission line with a maximum of 1000MW power capacity

3. Construction of 4 VSC converter stations (320/400kV)

4. Laying of first cable cluster connecting Das Island to shore, comprises three 400-kilovolt (kV) subsea cables of 135 kilometers (km) each

5. Laying of the second cable cluster connecting Al Ghallan island to shore, concerns four 320 kV submarine cables of 125 km each.

6. Electro-mechanical works

7. Civil works

8. Construction of associated facilities

03 January 2022

A consortium of Jan De Nul Group and Samsung C&T has been awarded the contract for a high-voltage direct current (HVDC) cable installation and convertors package with a contract value of US$3 billion. The scope of Jan De Nul includes the design, installation, burial, and protection of two cable clusters of almost 1,000km in total, connecting the islands Al Ghallan and Das in the Arabian Gulf to the onshore converter stations at Al Mirfa and Shuweihat in Abu Dhabi.

23 December 2021

Hitachi was appointed by Samsung C&T to install a high-voltage, direct current (HVDC) subsea transmission system. The scope of work includes the supply of four converter stations, which convert AC power to DC for transmission in the subsea cables, then reconvert it to AC from DC for use in the offshore power systems.
