GCCIA evaluates Oman-UAE grid link bids

27 January 2025

The GCC Interconnection Authority (GCCIA) is understood to be evaluating bids that it has received for a contract to build a direct interconnection between Oman's national transmission network and the regional electricity grid.

MEED reported in May 2023 that design work was under way for Oman’s second GCCIA link.

Oman Electricity Transmission Company (OETC), in its five-year capability statement published last year, said the GCCIA has agreed to construct the project.

"The new link will enhance system reliability and resiliency by increasing the total transfer capability up to 1,600MW between the Oman and GCCIA networks," OETC said.

The new direct interconnection comprises a 528-kilometre (km), 400-kilovolt (kV) double circuit overhead line between the existing Ibri independent power producer (IPP) 400kV grid station in Oman and the 400kV grid station in Al-SIlaa in the UAE.

MEED understands that the project includes two intermediate substations: one near Madinat Zayed in the UAE and the other adjacent to the Ibri substation in Oman.

Local contractor Bahwan Engineering Company is understood to be among the firms that have submitted proposals for the contract, which is valued at an estimated $1bn.

OETC said the principal technical benefits of connecting Oman directly to the GCCIA grid include the integration of spinning reserve requirements and the optimisation of generation dispatch. It also encourages renewable energy development and reduces fuel gas or diesel use by power generation and generation capacity requirements.

OETC noted that power exchange between Oman and its existing interconnection to the GCCIA amounted to 93,029.56 megawatt-hours (MWh) of exports and 85,089.46MWh of imports in 2023.

Oman’s first link with the GCCIA became operational in November 2011.

It comprises a 200kV line connecting the Mahadha grid station in Al-Wasit in Oman to the Al-Oha grid station in Al-Ain, UAE.

It is the third known project that aims to improve or expand linkages with the GCC grid. Projects are under way for interconnection with Kuwait, as well as with Iraq.

The GCCIA Al-Fadhili high-voltage direct current converter station in Saudi Arabia is undergoing a major upgrade, which will enable the GCC states to exchange up to 1,800MW of electricity daily using the grid.

OETC manages the grid in northern Oman and Dhofar at voltages of 400kV, 220kV and 132kV. One of the major OETC capital expenditure programmes is the execution of the first phase of the 400kV North-South Interconnector project.

In December 2020, Nama awarded State Grid Corporation of China the contract for the privatisation of OETC. Nama divested 49% of its shares in OETC to State Grid, which raised $1bn in capital.

  • Chinese contractor wins Morocco solar plant deal

    10 August 2026

    China Harbour Engineering Company (CHEC), a subsidiary of China Communications Construction Company (CCCC), has won a contract to build a solar photovoltaic (PV) power plant in Fez in northern Morocco.

    Known as GreenPower Morocco 4 (GPM4), the project is being developed by Moroccan company GPM Holding through its utility-scale solar subsidiary GPM Parks.

    The project covers engineering design, equipment procurement and installation, construction of an operation and maintenance building, grid connection and commissioning. It also includes upgrades to the associated substation.

    According to CHEC, the completed plant will supply electricity to the local grid, although it did not disclose the project’s capacity or contract value. 

    The project is being developed under Law 13-09, which provides Morocco’s framework for private renewable energy generation.

    According to its website, GPM Holding is also developing another solar PV project called GreenPower Morocco 2 (GPM2). This follows the completion of its first solar project, the 34MW project (GPM1) commissioned in Tangier in 2024. 

    GPM1 was developed by Green Power Morocco, a special purpose vehicle owned by GPM Holding and UAE-based Amea Power. The $30m project covers 75 hectares and includes 91,000 PV panels. It is expected to generate about 66,149MWh a year.

    The project has a 25-year power purchase agreement in place with Amendis, a subsidiary of Veolia Morocco. PowerChina was the main engineering, procurement and construction (EPC) contractor.

    Chinese contractors have previously been involved in other projects in Morocco’s renewable energy sector.

    Shandong Electric Power Construction Company (Sepco 3), a subsidiary of PowerChina, was part of the EPC consortium for the 200MW Noor 2 concentrated solar plants and 150MW Noor 3 concentrated solar power projects at the Noor Ouarzazate complex.

    New contract awards have been limited in Morocco in 2026, although six solar PV plants are now in the execution stage under phases one and two of the 305MW Noor Atlas solar PV programme.

  • Aramco puts out fire at Jizan refinery after Houthi strike

    10 August 2026

    Saudi Aramco said it had extinguished a fire that broke out at its Jizan refinery on Saudi Arabia’s Red Sea coast after the facility was hit in drone strikes by Yemen-based Houthi rebels on 9 August.

    The kingdom’s Ministry of Energy said the fire occurred at an Aramco refinery facility in Jizan and that emergency authorities had completed the necessary procedures to deal with the incident.

    The energy ministry did not say what started the fire, saying only that the incident caused no injuries.

    The Houthi rebels later claimed responsibility for the attack.

    The province of Jizan lies close to Saudi Arabia’s border with Yemen and has repeatedly been targeted by the Houthis in attacks on the kingdom’s energy infrastructure.

    The strike on the Jizan refinery was the second attack on the facility by the Houthis in as many weeks. Aramco shut the refinery on 27 July following a similar drone strike, which, according to media reports, damaged the integrated gasification combined-cycle unit and tank farm at the complex.

    On a call with investors to discuss Aramco’s second-quarter results, CEO Amin Nasser said recent attacks on the company’s facilities in the world’s top oil-exporting country had caused some disruption to production, but that he was confident operations could be restored quickly. He said the attacks had had no material operational or financial impact.

    Jizan refinery complex

    Saudi Aramco’s sprawling Jizan refinery complex entered operations in 2021.

    Aramco undertook the estimated $16bn-plus project in late 2010. The scheme consists of a refinery with an output capacity of 400,000 barrels a day (b/d), a major marine terminal and a 4GW combined-cycle power plant in Baish, in Saudi Arabia’s southwestern Jizan region.

    The Jizan refinery covers an area of 12 square kilometres. The complex processes Arabian Heavy and Arabian Medium crude grades to produce 80 million b/d of gasoline, 250 million b/d of diesel and more than 1 million tonnes a year of petrochemical products such as benzene and paraxylene.

    A multiple-pier marine terminal supports the supply of crude oil from oil fields located mainly in the kingdom’s Eastern Province to the refinery, as well as the export of surplus refined products to overseas markets. The terminal has been designed to accommodate very large crude carriers.

    A 4,000MW combined-cycle power plant uses approximately 90,000 b/d of vacuum residue from the refinery to generate electricity, hydrogen and water for the refinery, while conveying excess power to the national grid.

    The hydrocracker unit comprises two parallel trains with a combined capacity of 54,500 b/d. The diesel hydrotreater plant comprises two trains, each with a capacity of 87,500 b/d.

  • Spanish firm renews Yanbu desalination O&M contract

    10 August 2026

    Spain’s Aqualia has announced it has renewed a contract to operate and maintain three floating desalination plants in Yanbu on Saudi Arabia’s Red Sea coast.

    The contract was awarded by the National Shipping Company of Saudi Arabia (Bahri) and will run until 14 September 2028, with an option to extend for a further two years.

    The three reverse osmosis (RO) plants are mounted on barges and have a combined production capacity of 150,000 cubic metres a day (cm/d). Each plant has a capacity of 50,000 cm/d.

    The three plants were originally deployed at Al-Shuqaiq and are designed to be relocated along Saudi Arabia’s coastline according to water demand. The barges are currently located at Yanbu.

    The $255m floating desalination project was commissioned for the Saudi Water Authority in 2022, with Bahri as the developer and UAE-based Metitio as the main contractor.

    Bahri is publicly listed on the Saudi Exchange but has significant government ownership, with the Public Investment Fund (PIF) holding 22.5% and Saudi Aramco Development Company owning 20% of the company.

    Aqualia is providing operation and maintenance services in Saudi Arabia through its joint venture Haji Abdullah Alireza Integrated Services Company (Haaisco), in which it holds a 51% stake.
