Dubai to announce $22bn tunnels prequalified developers

16 December 2024

 

Dubai Municipality is expected to announce the list of prequalified developers for the first four packages of the $22bn Dubai Strategic Sewerage Tunnels (DSST) project imminently, according to a source close to the project.

Potential investors submitted their statements of qualifications (SoQs) for the contracts to develop and operate various packages of the project in late October.

MEED reported that the municipality received SoQs from over a dozen companies, including several prequalified as engineering, procurement and construction (EPC) contractors for the project’s first four packages.

According to industry sources, the companies that are keen to prequalify as investors or sponsors of the planned public-private partnership (PPP) project include:

  • Abrdn Investcorp Infrastructure Investments Manager (UK)
  • Besix (Belgium)
  • China Railway Construction Corporation (CRCC)
  • China Railway Engineering Group (CREG)
  • China State Construction Engineering Corporation (China)
  • Itochu (Japan)
  • Nesma Company (Saudi Arabia)
  • Plenary (Australia)
  • Samsung C&T (South Korea)
  • Vision Invest (Saudi Arabia)
  • Webuild (Italy)

Another source familiar with the project told MEED the expectation is for the client and its consultants to issue the prequalified developer list in early Q1 2025.

MEED previously reported that the bidders for the six PPP packages would be prequalified consortiums comprised of sponsors or investors; EPC contractors; and operations and maintenance contractors.

The overall project will require a capital expenditure of about AED30bn ($8bn), while the whole-life cost over the full concession terms of the entire project is estimated to reach AED80bn.

The investor prequalification process for the scheme comes after the client prequalified EPC contractors that can partner with the developers or investors to bid for the contracts.

MEED understands that packages J1 and W will be tendered together as separate contracts first, followed by J2 and J3, with the requests for proposals to be issued sequentially, staggered about six to 12 months apart.

DSST packages

Under the current plan, the $22bn DSST project is broken down into six packages, which will be tendered as PPP packages with concession periods lasting between 25 and 35 years.

The first package, J1, comprises Jebel Ali tunnels (North) and terminal pump stations (TPS). The tunnels will extend approximately 42 kilometres (km), and the links will extend 10km. 

The second package, J2, covers the southern section of the Jebel Ali tunnels, which will extend 16km and have a link stretching 46km.

W for Warsan, the third package, comprises 16km of tunnels, TPS and 46km of links.

J3, the fourth package, comprises 129km of links.

J1, J2, W and J3 will comprise the deep sewerage tunnels, links and TPS (TLT) components of the overall project.

J1, J2 and W will be procured under a design-build-finance-operate-maintain model with a concession period of 25-35 years.

J3 will be procured under a design-build-finance model with a concession period of 25-35 years. Once completed, Dubai Municipality will operate J3, unlike the first three packages, which are planned to be operated and maintained by the winning PPP contractors.  

The project’s remaining two packages entail expanding and upgrading the Jebel Ali and Warsan sewage treatment plants. MEED understands these packages will be procured at a later stage.

  • Egypt approves plans for 869MW wind power plant

    22 June 2026

    Egypt’s Cabinet has approved plans for French renewable energy developer Voltalia to develop an 869MW wind power project.

    The scheme will be built on land allocated by the New & Renewable Energy Authority (NREA), according to a statement posted by the Cabinet following its most recent weekly meeting.

    Voltalia will make an initial investment of $53m and has committed to achieving commercial operations by December 2028.

    Voltalia already operates the 32MW Ra solar plant at the Benban solar complex in Aswan and is expanding its renewable energy portfolio in Egypt.

    Previously, in 2024, it signed a framework agreement with Egypt’s Taqa Arabia to develop a green hydrogen and renewable power cluster near the Ain Sokhna port in the Suez Canal Economic Zone.

    The green hydrogen development is planned in two phases, each centred on a 500MW electrolyser powered by more than 1.3GW of renewable generation capacity. The project, still in its early stages, is expected to produce up to 350,000 tonnes of green ammonia a year.

    Voltalia’s partnership with Taqa Arabia also includes plans for a 3.2GW hybrid wind and solar project to repower the existing 545MW Zafarana wind farm in Suez Governorate. The Cabinet statement did not indicate whether the newly approved 869MW wind project forms part of that proposal.

    Meanwhile, the developer won another contract, earlier this year, to develop a 132MW solar power project in Tunisia’s Gabes region.

    The project, known as Wadi, marked Voltalia’s third major solar award in the country after the Sagdoud and Menzel Habib projects awarded in 2024.

  • Local firm signs Jeddah drainage contracts

    22 June 2026

    Local contractor Alkhorayef Water & Power Technologies (AWPT) has announced it has signed two contracts with Jeddah Municipality to operate and maintain stormwater and surface water drainage networks across the city.

    The contracts have a combined value of SR202.06m ($53.9m), and each will run for five years.

    The first contract, valued at SR108.46m ($28.9m), covers the operation and cleaning of stormwater and surface water networks in the South and Al-Malisa sub-municipalities.

    The second contract, worth SR93.59m ($25m), covers similar services for the Airport Sub-Municipality.

    In March, MEED reported that the firm had won a long-term contract to carry out work in the airport’s sub-municipality area. The agreement was signed on 16 June.

    Elsewhere, construction has yet to begin on phases one and two of the King Abdullah Road-Falasteen Road tunnel project, each valued at about $175m.

    According to sources, Jeddah Municipality selected Saudi contractor Thrustboring Construction Company to build the large-diameter stormwater drainage tunnels in 2025. However, an official agreement has yet to be signed.

    The municipality was also previously planning to rehabilitate the existing Al-Zahra pumping station. Prequalification for the project began in 2020; however, it is understood that the main contact tender was cancelled last year.

  • Egypt signs gas deal with Harbour Energy

    22 June 2026

    Egypt’s Ministry of Petroleum & Mineral Resources has signed a new agreement with London-headquartered Harbour Energy.

    Under the scope of the agreement, Harbour Energy will drill two new exploration wells and carry out maintenance work for one of the existing wells within the Dsouq-1 development contract.

    Harbour Energy committed an initial $6m investment and a $1m signing bonus for the Dsouq concession. Total investment could rise to $18m if commercial discoveries are made.

    The signing was witnessed by Egypt’s Minister of Petroleum, Karim Badawi.

    He said that his ministry is continuing to implement a package of investment measures and incentives aimed at encouraging partners to increase investments and intensify exploration, development and production activities.

    The agreement was signed by Syed Saleem, a member of the executive branch of the state-owned Egyptian Natural Gas Holding Company (EGAS), and Samah Sabry, the executive director of Harbour Energy for the Middle East and North Africa region.

    Harbour Energy drilled two new wells in Egypt during the fiscal year 2025/2026, resulting in the addition of reserves estimated at 35 billion cubic feet of gas.

    The company aims to drill three new exploration wells during the fiscal year 2026/2027.

    Egypt is currently pushing to boost the production of both oil and gas in its territory.

    Earlier this month, Egypt’s Ministry of Petroleum & Mineral Resources announced that it had fully settled all outstanding arrears owed to oil and gas companies.

    Two years ago, in June 2024, the country owed approximately $6.1bn to partners in the oil and gas sector.

  • Iran invites companies to register for Kharg Oil Terminal development

    22 June 2026

     

    Iran has invited companies to participate in a project to develop the existing Kharg Oil Terminal, according to documents released by the state-owned National Iranian Oil Company and Iranian Oil Terminals Company.

    The project focuses on developing units capable of receiving, storing and exporting extra-heavy West Karun crude oil at a rate of 700,000 barrels a day.

    The scope of the project includes design, purchase, installation and commissioning of the new facility.

    The contract will use the engineering, procurement and construction (EPC) model, according to the tender documents.

    The project aims to use existing oil storage tanks and reconstruct the deepwater crude oil export berth known as Berth Number One.

    The berth known as Berth Number Three will serve as a backup berth for the project.

    The winning bidder for the contract will be responsible for a range of works, including:

    • Carrying out all stages of verification of the project’s basic design, design and engineering
    • Supply and procurement of goods and materials
    • Execution and installation
    • Pre-commissioning and commissioning

    The project is expected to take 30 months to complete, and the winning contractor will also be responsible for maintaining the facility for a further 12 months.

    Companies that wish to submit bids need to do so through Iran’s Government Electronic Procurement System (Setad).

    Companies interested in participating in the tender have seven days from the publication of the tender notice to receive the documents.

    They then have a further 14 days to upload the required documents into the government procurement system.

    Iran exports most of its oil via the Kharg Oil Terminal on Kharg Island.

    US President Donald Trump said strikes in mid-March “obliterated” Kharg’s military assets but did not target the island’s oil infrastructure.

    He warned that if Iran continued disrupting traffic through the Strait of Hormuz, he would reconsider the decision to spare energy targets on the island.

    Trump has threatened several times to take “control” of Kharg Island, but he has not yet followed through on this threat.

    The small coral island is located 33 kilometres from Iran’s coast and has strategic importance because Iran’s coastline is mostly too shallow for large tanker ships to dock.
