Mitsubishi Power to supply Rumah 1 and Nairiyah 1 turbines

21 November 2024

 

The developer and engineering, procurement and construction (EPC) teams that will develop and build the Rumah 1 and Nairiyah 1 combined-cycle gas turbine (CCGT) schemes in Saudi Arabia are understood to have partnered with Tokyo-headquartered Mitsubishi Power for the gas turbines to power the plants.

The Rumah 1 and Nairiyah 1 independent power projects (IPPs) will each have a capacity of 1,800MW.

The principal buyer, Saudi Power Procurement Company (SPPC), previously indicated that the power plants would operate using natural gas combined-cycle technology with a carbon-capture unit readiness provision.

A consortium comprising Saudi Electricity Company (SEC), Riyadh-based utility developer Acwa Power and South Korea’s Korea Electric Power Corporation (Kepco) won the contract to develop the two CCGT IPPs.

The consortium signed the power-purchase agreements (PPAs) for the two projects with SPPC on 18 November.

China’s Sepco 3 and South Korea’s Doosan Enerbility will undertake the EPC contract for the projects, as MEED reported.

The SEC, Acwa Power and Kepco team offered a levelised electricity cost (LCOE) of $cents 4.5859 a kilowatt-hour (kWh) for Rumah 1, and $cents 4.6114/kWh for Nairiyah 1.

Acwa Power said that the two IPPs will require a combined investment of approximately SR15bn ($4bn). The IPPs are expected to reach commercial operations in Q2 2008. 

Rumah 1 is located in the Central Region in Riyadh and is part of the previously planned Riyadh Power Plant 15 (PP15). Nairiyah 1 is located in the Eastern Region.

SPPC received bids for the contracts for four thermal IPPs – the other two being the similarly configured Rumah 2 and Nairiyah 2 – on 21 August.

The four power generation facilities will be developed using a build-own-operate (BOO) model over 25 years. 

SPPC’s transaction advisory team for the Rumah 1 and 2 and Al-Nairiyah 1 and 2 IPP projects comprises US/India-based Synergy Consulting, Germany’s Fichtner and US-headquartered Baker McKenzie. 

Najm and Mitsubishi Power

The Rumah and Nairiyah 2 orders will be the second this year for Mitsubishi Power, which in August confirmed receiving an order from South Korea's Samsung C&T Corporation to provide its M501JAC hydrogen-ready CCGT for the Najim industrial steam and electricity cogeneration plant in Jubail in the Eastern Province of Saudi Arabia.

The M501JAC gas turbine will enable the new cogeneration plant to generate up to 475MW of power and approximately 452 tonnes an hour of steam.

Samsung C&T is the EPC contractor for the project, which is being developed by a team comprising Abu Dhabi National Energy Company (Taqa) and Japanese power generation company Jera. This is the same team that won the contract to develop and operate the Rumah 2 and Nairiyah 2 CCGT contracts.

  • Populous wins Bahrain Sports City contract

    21 April 2026

     

    US-based engineering firm Populous has won a BD5m ($13.5m) contract for the Sports City development at Sakhir in Bahrain.

    The contract was awarded by Bahrain’s Ministry of Works, Municipalities Affairs & Urban Planning.

    The scope covers pre-contract consultancy services, including finalising the masterplan and internal infrastructure, completing phase 1A design works and preparing tender documents.

    Populous is a specialist sports venue designer that formerly operated as part of HOK Group.

    The contract was first tendered in 2021, when Populous emerged as the sole bidder.

    At the time, it was reported that Sports City would include Bahrain’s largest sports stadium and a multi-purpose indoor sports arena.

    The project is expected to provide renewed impetus to Bahrain’s construction and transport sector, which has struggled in recent years, with the total value of awarded contracts falling for a third consecutive year.

    According to regional project tracker MEED Projects, about $400m-worth of contracts had been awarded in Bahrain by the end of October last year – less than half the $1.2bn recorded during the same period the previous year.

    The sector has yet to return to pre-pandemic levels. Before 2020, Bahrain consistently awarded more than $2bn in contracts annually, peaking at nearly $4bn in 2016.

    Bahrain’s construction industry is forecast to record average annual growth of 4.9% in 2026-29, supported by investments in transport infrastructure and renewable energy projects aligned with Bahrain’s Economic Vision 2030.

    Vision 2030 includes the BD11.3bn ($30bn) Strategic Projects Plan, unveiled in October 2021, encompassing 22 national infrastructure projects. It also includes plans to create five new cities by 2030: Fasht Al-Jarm, Suhaila Island, Fasht Al-Azem, Bahrain Bay and the Hawar Islands.

    Growth over the forecast period is also expected to be driven by investments under the National Renewable Energy Action Plan, which targets a 30% reduction in carbon emissions by 2035, compared to 2015 levels, and aims to achieve net-zero emissions by 2060.

  • Egypt to build Olympic Village project on Red Sea

    21 April 2026

    Egypt has moved to back a major new sports development on the Red Sea coast, officially assigning a 225-acre plot for a planned Olympic Village in the Red Sea Governorate.

    The site is located opposite the resort destination of El-Gouna, giving the project access to an established tourism corridor.

    The development is intended to strengthen Egypt’s ambition to become a hub for international sports tourism, with facilities designed to support large-scale regional and global championships.

    Plans include stadiums and purpose-built arenas designed to meet Olympic-level requirements, enabling the complex to accommodate multiple sports and event formats.

    To support visiting delegations and spectators, the Olympic Village is expected to include on-site hospitality facilities, including a hotel.

    The project is intended to operate as an integrated, self-contained destination capable of staging regional and international tournaments, while also leveraging the Red Sea’s year-round appeal for camps, friendlies and seasonal training programmes.

    According to UK analytics firm GlobalData, Egypt’s residential construction sector is expected to grow by 8.3% from 2026 to 2029, supported by investments in the housing sector and the government’s focus on addressing the country’s growing housing deficit amid a rising population.

    The commercial construction sector is expected to register real-term growth of 6.6% in 2026-29, supported by a rebound in the tourism and hospitality markets and an improvement in investment in office buildings and wholesale and retail trade activities.

  • Algeria launches oil and gas licensing round

    21 April 2026

    Algeria has launched a new bid round offering seven exploration blocks to international companies.

    The round was launched by the National Agency for the Valorisation of Hydrocarbon Resources (Alnaft), which manages and regulates the upstream oil and gas sector in the country.

    The blocks are located in the regions of Ouargla, Illizi, Touggourt and El-Bayadh. Both oil and gas assets are included.

    The blocks on offer are:

    • Est Bordj Omar Driss 1
    • Illizi Centre 1
    • El-M’Zaid Nord
    • El-Borma 2
    • El-Hadjira 3
    • El-Benoud Est
    • Touggourt Sud

    Technical evaluation of bids will cover exploration, development and production optimisation plans.

    All bids – except those for Est Bordj Omar Driss 1– will also be assessed against financial criteria, including the bidder’s participation rate in financing upstream operations.

    Successful bidders will access the assets through contracts with Sonatrach, either via production service agreements or participation agreements, depending on the block.

    Algeria is currently seeing an uptick in demand for its gas exports due to the disruption to exports from Qatar and the UAE in the wake of the US and Israel’s attack on Iran on 28 February.

  • Nakheel awards $143m Dubai Islands infrastructure deal

    20 April 2026

    Register for MEED’s 14-day trial access 

    Dubai-based developer Nakheel, now part of Dubai Holding, has awarded a AED527m ($143m) contract for the construction of the primary infrastructure and utilities works on Island B at the Dubai Islands development.

    The contract was awarded to local firm Al-Nasr Contracting Company.

    The scope covers the construction of roads, water networks, electrical and telecommunications networks, drainage and sewerage systems, and integration with the district cooling plant network at Island A.

    In October last year, Nakheel awarded Al-Nasr Contracting Company a AED169m ($46m) contract for the construction of the internal roads and utilities for the Bay Villas development at Dubai Islands.

    In August, MEED reported that Nakheel had awarded a AED2.6bn ($708m) contract to Abu Dhabi-based Fibrex Contracting to build the Bay Villas project at Dubai Islands. The contract includes the construction of 636 villas.

    The Dubai Islands development consists of five islands spanning 18.6 square kilometres. It features more than 59 kilometres (km) of waterfront and 20km of beaches, as well as parks, golf courses, promenades and cycling paths.

    The offshore island project gained renewed momentum in 2022, when Nakheel unveiled a new masterplan and rebranded it as Dubai Islands.

    The reclaimed islands were originally part of the Palm Deira project, which was partially completed before being put on hold in 2008.
