Doosan Enerbility wins $611m Riyadh plant expansion deal

14 March 2025

South Korean contracting firm Doosan Enerbility has signed a contract with Saudi Electricity Company to construct the Riyadh Power Plant 12 (PP12) combined-cycle gas turbine (CCGT) power plant in Saudi Arabia.

A local media report citing a company official said the contract is valued at KD890bn ($611m).

MEED exclusively reported in November last year that a team of Doosan Enerbiilty and China-headquartered Sepco 3 would undertake the expansion project for Riyadh Power Plant 12 (PP12).

The greenfield CCGT power plant will have a generation capacity of 1,800MW.    

MEED understands that Doosan Enerbility will be responsible for the design, central equipment supply and integrated commissioning of the PP12 expansion project.

Located about 150 kilometres northwest of the capital Riyadh, the power plant is expected to be completed in 2028.

Saudi Arabia is expanding two other thermal power plants in addition to PP12. Saudi utility developer and investor Acwa Power will develop the expansion projects for Hajr and Marjan, which have respective capacities of 3,600MW and 1,800MW.

It is suggested, but not confirmed, that Sepco 3 will undertake the EPC contract for both schemes.

Saudi Arabia is ramping up the development and construction of gas-fired power stations in line with its liquid-fuel displacement programme. 

According to the Energy Institute, oil accounted for 152.1 terawatt-hours (TWh), or about 36%, of the total electricity generation in Saudi Arabia in 2023, which stood at 422.9TWh.

Latest available data from MEED Projects and MEED suggests that generation and cogeneration plants powered by natural gas account for two-thirds, or 66.7%, of the 53GW total capacity under construction in the kingdom as of March.


MEED’s April 2025 report on Saudi Arabia includes:

> POWER: Saudi power sector enters busiest year
> WATER: Saudi water contracts set another annual record
> UPSTREAM: Saudi oil and gas spending to surpass 2024 level

> DOWNSTREAM: Aramco’s recalibrated chemical goals reflect realism
> CONSTRUCTION: Reprioritisation underpins Saudi construction
> TRANSPORT: Riyadh pushes ahead with infrastructure development
> BANKING:
 Saudi banks work to keep pace with credit expansion

  • Riyadh sets December deadline for Prince Mishaal Road

    20 November 2025

     

    The Royal Commission for Riyadh City (RCRC) has allowed contractors until 3 December to submit bids for a contract to develop Prince Mishaal Bin Abdulaziz Road Axis-Taif Road in Riyadh.

    The previous deadline was 19 November.

    The scope of work covers general road improvement works, including street upgrades, drainage works, relocation of existing utilities, dry and wet utilities, and other associated infrastructure. RCRC is investing in improving the road network in and around the kingdom's capital.

    Earlier in November, MEED reported that RCRC had begun post-tender clarifications with bidders for a contract covering upgrade works on Najm Al-Din Al-Ayoubi Road in Riyadh.

    The scope of work covers general road improvement works, including upgrades to three bridges at Al-Zahabi Road, Abdulrahman Adakhel Road and Atia Al-Saady Road.

    In February, RCRC announced plans to develop eight road projects in Riyadh at an estimated cost of more than SR8bn ($2bn).

    The projects form part of the second group in the Riyadh Ring Roads and Main Axes development programme.

    The schemes include:

    • The northern part of the Prince Turki Bin Abdulaziz Al-Awwal Road development project, with a length of more than 6 kilometres (km). The scope includes the development of two main intersections, the construction of three bridges and a tunnel.
    • The middle section of the Al-Thumama Road Axis development project. The scheme will cover about 10km and includes the development of five main intersections and the construction of 11 bridges and five tunnels.
    • The Imam Abdullah Bin Saud Road development project, which will stretch about 9km and includes the development of four main intersections, the construction of three bridges and two tunnels.
    • The Dirab Road development project, which will cover 9km and includes the development of two main intersections and the construction of nine bridges.
    • The Imam Muslim Road development project, which stretches 12km and includes the development of four main intersections and the construction of four bridges. The project will serve as the future extension of the Prince Turki Bin Abdulaziz Al-Awwal Road Axis to the south.
    • The road network development project surrounding King Abdullah Financial Centre, with a length of 20km. This includes the development of three main intersections and the construction of 19 bridges.
    • The construction of a bridge at the intersection of King Salman Road in the east with Abu Bakr Al-Siddiq Road in the north.
    • The first package of engineering modifications for crowded sites in Riyadh, encompassing improvements to alleviate traffic congestion during peak times.

    In August last year, RCRC confirmed it had awarded four contracts worth SR13bn ($3.46bn) as part of the first phase of the programme to develop the city’s road network.

    RCRC said the first phase will develop the axis of the main and ring roads to improve traffic movement in the city.

    Other major projects by RCRC include Riyadh Metro, Riyadh Art, Sports Boulevard, King Salman International Park and the Green Riyadh project.

  • Riyadh advances with rail link prequalifications

    20 November 2025

     

    Saudi Arabia Railways (SAR) is expected to begin the second stage of the prequalification process for a contract covering the construction of a new railway line, known as the Riyadh Rail Link, which will run from the north to the south of Riyadh.

    MEED understands that the consortiums need to propose self-funded financing arrangements for the project as part of the new round of prequalifications.

    Contractors submitted their initial prequalification documents earlier this month.

    The scope of work includes constructing a 35-kilometre-long double-track railway line connecting SAR’s North-South Railway to the Eastern Railway network.

    The contract also covers the procurement, construction and installation of associated infrastructure such as viaducts, civil works, utility installations, signalling systems and other related works.

    The project is expected to form a key component of the Saudi Landbridge railway.

    The Saudi Landbridge is an estimated $7bn project comprising more than 1,500km of new track. Its core component is a 900km new railway between Riyadh and Jeddah, which will provide direct freight access to the capital from King Abdullah Port on the Red Sea.

    Other key sections include upgrades to the existing Riyadh-Dammam line and a link between King Abdullah Port and Yanbu.

    The start of tendering activity for the Riyadh Rail Link project makes the construction of the Saudi Landbridge more likely. 

    The project is one of the kingdom’s most anticipated infrastructure programmes. Plans to develop it were first announced in 2004, but the project was put on hold in 2010 before being revived a year later.

    Key stumbling blocks were rights-of-way issues, route alignment and its high cost.

    In December 2023, MEED reported that a team of US-based Hill International, Italy’s Italferr and Spain’s Sener had been awarded the contract to provide project management services for the programme.

    If it proceeds, the Landbridge will be one of the largest railway projects ever undertaken in the Middle East – and among the biggest globally.

  • Wood Group wins Iraq oil contract

    20 November 2025

    Register for MEED’s 14-day trial access 

    Aberdeen-based Wood Group has won a contract to deliver project management and engineering services for PetroChina at the West Qurna-1 oil field in southern Iraq, according to a statement from the company.

    Under the terms of the contract, Wood will manage engineering, procurement and construction (EPC) projects at the field. 

    Located approximately 50 kilometres northwest of Basra, West Qurna-1 holds more than 20 billion barrels of recoverable reserves.

    Ellis Renforth, Wood’s president of operations for the Europe, Africa and Middle East region, said: “This contract award deepens our decade-long partnership at West Qurna-1 and reflects the continued trust placed in Wood to deliver complex energy solutions in Iraq. 

    “We’re proud to combine our global expertise with a strong local workforce to help support Iraq’s energy ambitions.”

    The contract will be delivered by nearly 200 Wood employees based in Iraq and the UAE, the company said.

    On 17 November, in a vote, 88% of Wood Group’s shareholders backed the company’s takeover by Dubai-based Sidara.

    The vote came after months of delay, while Wood struggled to agree its accounts with its auditor.

    The company’s accounts were eventually published on 30 October, showing a pre-tax loss of more than £2bn and evidence that the auditor was still not satisfied with the figures going back several years.

    Wood Group accepted a $292m conditional takeover bid from Sidara in August.

    As of February, Wood Group employed 35,000 people across about 60 countries, many in consulting and engineering roles.

    In the Middle East, the company has project contracts in Iraq, Kuwait, Oman, Qatar, Saudi Arabia and the UAE, where it has opened its third office in Sharjah.
