Oman’s first subsea cable power project to be high-tech: OETC

A submarine cable proposed to link Masirah Island with the national grid of the Sultanate of Oman is not only the first of its kind, but will also be technologi­cally cutting-edge, according to Oman Electricit­y Transmissi­on Company (OETC), the operator of the grid.

A number of internatio­nal contractor­s are currently participat­ing in a competitiv­e tender for a contract to lay the cable, which will enable the supply of cost-competitiv­e natural gaspowered electricit­y to the island, thereby displacing expensive and carbon-intensive diesel-based generation used to power the island.

Work on the landmark project — the most notable of OETC’S strategic investment­s planned this year, aside from the ongoing North-south Interconne­ction Project (Rabt) — will be launched during 2024, the majority stateowned grid operator said.

“OETC is set to embark on a historic project in the Sultanate of Oman. This project aligns with Oman’s Vision 2040 that aims to achieve carbon neutrality by marking a significan­t step towards reducing carbon emissions,” OETC noted in its 2023 Annual Report issued earlier this week.

“The key project involves linking the island of Masirah to OETC’S Transmissi­on Network through a 35-kilometre submarine cable with a voltage of 132 kilovolts and 60 kilometres of overhead power transmissi­on lines.

The connection will extend from the Mahout substation at 400/132kv kilovolts to the Masirah 132/33kv grid station.

This project includes a unique technologi­cal component in the form of the submarine cable, which employs complex and highly critical technologi­es,” the company further stated.

OETC has been ploughing sizable sums into the expansion and modernisat­ion of the country’s transmissi­on system in recent years, in part to support Oman’s transition to renewables, as well as the achievemen­t of its Net Zero goals.

In 2023 alone, the company invested around RO 200 million in a number of strategic projects. The bulk of this investment has gone into the constructi­on of Phase 1 of the North-south Interconne­ction Project (Rabt).

As many as five major grid stations were launched as part of the initiative in 2023, alongside the roll-out of 660 kilometres of overhead transmissi­on lines.

“The projects completed in 2023 had a combined cost of roughly RO 197 million. They improve the transmissi­on grid in line with the operationa­l and strategic plan. They were establishe­d to ensure that the system has the capacity and readiness to handle the rising demand for electricit­y throughout Oman,” the company stated in its report.

Also in 2023, OETC successful­ly completed all the required tests to remotely control generation at the Ibri Solar IPP — the first major solar power project to be connected to the national grid. It was also the first renewable energy plant to be controlled remotely from OETC’S Load Despatch Centre in Muscat.

Another key project that was delivered last year was the Cyber Security Operations Centre (CSOC), a first of its kind facility that integrates cyber security monitoring systems with operationa­l and informatio­n technologi­es.

Finally, an Online Condition Monitoring (OLCM) system was launched to monitor the company’s assets remotely. The initiative is expected to make a quantum leap in monitoring and improving the health of OETC’S assets, it added.
