Sheikh Mohammed inaugurates Dubai CSP plant

7 December 2023

Sheikh Mohammed bin Rashid al-Maktoum, UAE Vice President and Prime Minister and Ruler of Dubai, has inaugurated the fourth phase of the Mohammed bin Rashid al-Maktoum (MBR) Solar Park in Dubai.

The 950MW fourth phase of the MBR solar park required an investment of AED15.78bn ($4.34bn).

It uses hybrid technologies: 600MW from a parabolic basin complex, 100MW from the CSP tower, and 250MW from solar photovoltaic (PV) panels.

The independent power producer (IPP) project features the tallest solar tower in the world, at 263.126 metres, and a thermal energy storage facility with a capacity of 5,907 megawatt-hours (MWh), the world's largest according to the Guinness World Records.

The project covers an area of 44 square kilometres. It features 70,000 heliostats that track the sun’s movement. The molten salt receiver (MSR) on top of the solar power tower is the core and the most important part of the CSP plant. It receives solar radiation and turns it into thermal energy.

The MSR contains over 1,000 thin tubes that enable the absorption of sun rays and their transfer to the molten salt within these tubes.

The project can power approximately 320,000 residences with clean and sustainable energy. It will reduce carbon emissions by about 1.6 million tonnes annually.

The completion of the project's fourth phase brings the total capacity of the MBR solar park to 2,863MW so far. The phases and their capacities are:

  • 13MW solar PV phase one: Completed in 2013
  • 200MW solar PV phase two: Commissioned in 2017
  • 800MW solar PV phase three: Commissioned in 2020
  • 950MW hybrid CSP/solar PV phase four: Inaugurated in 2023
  • 900MW solar PV phase five: Commissioned in 2023

Dewa is aiming for the MBR development to reach 5,000MW of capacity by 2030. It recently awarded the UAE-based Masdar the contract to develop the solar park's sixth phase, which has capacity of 1,800MW.

Project background

Dubai Electricity & Water Authority (Dewa) awarded a consortium of Saudi Arabia’s Acwa Power and China's Silk Road Fund the contract to develop a 700MW CSP plant with storage for the fourth phase scheme in November 2017. Since then, the project has been expanded to include a 250MW solar PV component.

Acwa Power then awarded Shanghai Electric the $3.8bn EPC contract for the hybrid CSP/PV plant in early 2018.

The project reached financial closure in March 2019. The cost will be met through $2.9bn of debt and $1.5bn of equity.

According to the project structure, Dewa is to provide $750m, or half of the project equity. Project developers Acwa Power and the Silk Road Fund will provide 51 per cent and 49 per cent, respectively, of the remaining equity.

The fourth phase project achieved a tariff of 7.3 $cents a kilowatt hour ($c/kWh) for the CSP component and 2.4$c/kWh for the PV capacity, two of the lowest tariffs for CSP and PV solar technology in the world at the time of award.

Dewa holds a 51 per cent stake in the project company, Noor Energy 1, set up to develop the plant, with Acwa Power and the Silk Road Fund holding the remaining stake. The developer consortium has signed a 35-year power-purchase agreement to supply power to Dubai’s grid.

  • Solar deals signal Saudi Arabia’s energy ambitions

    13 February 2026

    Commentary
    Mark Dowdall
    Power & water editor

    Saudi Arabia’s recent agreement to build $2bn-worth of solar power plants in Turkiye is the latest sign that the kingdom’s energy influence is changing.

    Historically, this was measured in oil barrels and export volumes. Increasingly, this is extending to capital, structuring expertise and the ability to deliver record-low tariffs in competitive markets.

    Announcing the deal, Turkish Energy Minister Alparslan Bayraktar said tariffs for the plants would be the country’s lowest on record, with electricity purchased under 25-year power purchase agreements.

    It followed another announcement, in January, that Acwa is investing $200m to build a large-scale solar photovoltaic (PV) plant in the Philippines.

    Whether Saudi-backed companies ultimately retain long-term stakes or primarily develop and build the assets, their role at the front end is significant.

    Sponsors that bring sovereign backing, clear procurement processes and access to low-cost financing can influence tariffs and contract terms from the outset.

    There is also a geopolitical layer. Investing in Turkiye, or anywhere for that matter, strengthens political and economic ties at a time when regional alignments are shifting.

    Energy infrastructure is also long-term by its nature. It connects ministries, regulators, lenders and operators in relationships that often extend well beyond a single transaction.

    Saudi Arabia has spent the past few years refining its approach to pricing, structuring and financing large-scale renewables at home.

    Exporting that expertise may not rival oil in scale or visibility, but it does signal that Saudi Arabia is becoming more than just an energy supplier.

    Increasingly, it is becoming a participant in how other countries design and finance their energy transitions. That influence is still significant.

    King Salman Bin Abdulaziz Al-Saud has made a series of senior government changes, including Khalid Al-Falih leaving his role as investment minister to become minister of state and a member of the cabinet.

    Al-Falih has been replaced by Fahad Al-Saif as investment minister. Al-Saif has been head of the Investment Strategy and Economic Insights Division at the Public Investment Fund (PIF) since 2024. That role involved formulating PIF’s long-term investment strategy. He has also served as head of the Global Capital Finance Division, a role he has held since joining PIF in 2021.

    The change of investment minister comes at a time when securing investments has become a key priority for Saudi Arabia as it prepares to hand over more projects to the private sector for delivery.

    King Salman also named Abdullah Al-Maghlouth as vice-minister of media and Abdulmohsen Al-Mazyad as vice-minister of tourism. Khalid Al-Yousef was named attorney general, and Sheikh Ali Al-Ahaideb will serve as president of the Board of Grievances.

    Faihan Al-Sahli was selected as director general of the General Directorate of Investigation, while Abdulaziz Al-Arifi was chosen to lead the National Development Fund. Haytham Al-Ohali will head the Communications, Space and Technology Commission, and Fawaz Al-Sahli will chair the Transport General Authority.

  • Indian firm wins major Oman substation contract

    12 February 2026

     

    India’s Larsen & Toubro has won a contract to build the Majan 400/220/132kV grid station in Oman.

    Estimated to cost $100m, the project includes an associated 400kV line-in line-out underground cable from Sohar Free Zone to the Sohar Interconnector Station.

    The contract was awarded by Oman Electricity Transmission Company (OETC), part of the government-owned Nama Group.

    The grid station will comprise eight 400kV gas-insulated switchgear (GIS) bays, eight 220kV GIS bays and 10 132kV GIS bays at the new Sohar Free Zone substation.

    The scope includes the installation of two 500MVA, 400/220kV transformers and two 500MVA, 220/132kV transformers.

    Local firm Monenco Consulting Engineers was appointed in April last year to provide design and supervision services for the project.

    As MEED exclusively revealed, the main contract was tendered in June, as part of three significant contracts to build new substations in the sultanate.

    The second contract, worth about $35m, covers the construction of the Sultan Haitham City 132/33kV grid station and associated 132kV line-in line-out underground cables running 4 kilometres from Mabella to Mabella Industrial Zone.

    The third contract, valued at about $100m, covers the construction of the Surab 400/33kV grid station and an associated 400kV line-in line-out cable from the Duqm grid station to the Mahout grid station. 

    Local firms Muscat Engineering Consulting and Hamed Engineering Services are consultants for the Sultan Haitham City and Surab projects, respectively.

    The two remaining contracts are currently under bid evaluation, with awards expected this quarter.

  • Developers appoint contractor for $500m wastewater treatment project

    12 February 2026

     

    Register for MEED’s 14-day trial access 

    Egypt’s Orascom Construction has won the engineering, procurement and construction (EPC) contract for a major wastewater treatment project in Saudi Arabia’s Eastern Province.

    A consortium of Saudi utilities provider Marafiq, the regional business of France’s Veolia and Bahrain/Saudi Arabia-based Lamar Holding is developing the $500m (SR1.875bn) industrial wastewater treatment plant (IWWTP) in Jubail Industrial City 2.

    Sources close to the project confirmed the appointment to MEED, adding that the project has now entered the construction phase.

    Industry sources also said that financial close on the project is expected to be reached in the coming days.

    In September, the developer consortium was awarded a contract, under a 30-year concession agreement, by Saudi Aramco Total Refining & Petrochemical Company (Satorp), a joint venture of Saudi Aramco and France’s TotalEnergies.

    The planned facility will treat and recycle wastewater from Satorp’s under-construction Amiral chemical derivatives complex, also in Jubail.

    Marafiq, formally Power & Water Utility Company for Jubail and Yanbu, will own a 40% stake in the dedicated project company. Veolia Middle East SAS will hold a 35% stake, and Lamar Holding’s Lamar Arabia for Energy will hold the other 25%.

    The planned IWWTP, which will primarily serve the $11bn sprawling Amiral chemicals zone, will implement advanced water treatment and recovery technologies to process complex industrial effluents, including spent caustic streams. Treated water will be reintegrated into the industrial processes, supporting closed-loop reuse and energy efficiency.

    The project follows a concession-style model, akin to a public-private partnership (PPP), where the developer consortium invests in, builds and operates the wastewater plant over a 30-year period, with returns linked to service delivery.

    Marafiq has been involved in several similar projects across Saudi Arabia, including as the sole owner of the Jubail industrial water treatment plant (IWTP8), which treats complex industrial effluents for petrochemical and heavy industrial companies.

    In 2020, Saudi Services for Electro Mechanic Works was awarded the $202m main contract for the fourth expansion phase of IWTP8. Construction works on the project are expected to be completed by the end of the quarter.

  • Dewa raises Empower stake in $1.41bn deal

    12 February 2026

    Dubai Electricity & Water Authority (Dewa) has announced it has increased its stake in Emirates Central Cooling Systems Corporation (Empower) from 56% to 80%.

    The transaction was completed through the purchase of 2.4 billion shares and the transfer of the entire ownership of Emirates Power Investment (EPI), which is wholly owned by Dubai Holding.

    The total value of the deal is AED5.184bn ($1.41bn).

    Empower currently holds over 80% of Dubai’s district cooling market and operates 88 district cooling plants across the emirate.

    According to MEED Projects, the UAE’s district cooling sector currently has nine projects worth $1.29bn in the pre-execution phase.

    Empower has ownership in four of these projects, which have a combined value of $472m.

    This includes a $200 million district cooling plant at Dubai Science Park, with a total capacity of 47,000 refrigeration tonnes serving 80 buildings.

    Empower signed a contract to design the plant last August, with construction scheduled to begin by the end of the first quarter of 2026.

    The utility is also building a district cooling plant at Dubai Internet City.

    UAE-based TMF Euro Foundations was recently appointed as the enabling and piling subcontractor for the project.
