Iberian power outage offers valuable lessons

The root cause of the power outages that gripped parts of the Iberian Peninsula on 28 April has yet to be established, pending a detailed investigation into what triggered the loss of power in large swathes of Portugal and Spain.

Ongoing investigations aside, Spain’s national electricity grid operator, Red Electrica, has ruled out a cyber attack or sudden spike in renewables as the main cause of the outage, which affected transport, retail and healthcare services, among others.

Insurance claims arising from the outages could reach between $300m and $600m in Spain and significantly less in Portugal, according to some sources, while the Riyadh-based Digital Cooperation Organisation cites losses of up to €1.3bn ($1.47bn) for the Spanish economy, based on Spain’s self-employed workers’ association, ATA.

But the highest cost could come in a non-monetary form. It would require probing into Spain’s utility infrastructure, which Red Electrica describes as Europe’s “best and most resilient”, and that of every European country and everywhere else.

Red Electrica president Beatriz Corredor has been quick to defend her firm, saying there is no such thing as zero risk.

The speed at which Spain, which exports renewable power to Portugal, restored power in affected areas lends credence to Red’s best-in-Europe claim if one is willing to forego the question of how it could have happened or been avoided in the first place.

Pending the results of the investigation, analysts and experts have offered their insights on the subject.

Writing on Linkedin, Thierry Lepercq, founder and president at Hydeal, describes the Spanish blackout as “the most significant power event in decades”, adding it is likely the first of a series of crippling crashes that will result from the inherent conflict between decarbonisation, or aiming at 100% renewables; security of supply; and energy affordability.

Lepercq is confident that the lesson will soon be clear: the power outage was all about inertia.

He predicts that the lack of electricity system planning will necessitate radical action. This could involve the “near complete” stop of new variable – solar and wind – installations and the fast ramp-up of fully-dispatchable, inertia-providing capacity from combined-cycle gas turbines (CCGTs) initially powered by natural gas, and as soon as possible, from competitive green hydrogen.

Another senior consultant at an international engineering services firm with offices in Dubai tells MEED that, considering a lot of caveats, the blackout resulted from a mix of high solar reliance, low grid inertia, voltage oscillations and insufficient backup systems, with no single cause confirmed. Some tripping, which catalysed the inertia problem, has also been reported, he notes. 

Prevention strategies could include enhancing firm power, expanding storage, improving monitoring and strengthening interconnections.

Morocco, for instance, played a key role in restoring power to Spain, highlighting the benefits of power pooling, where countries share an integrated generation capacity and grid stability across borders.

Reviewing energy policies is also key, such as looking at grid codes with clearer requirements on how much energy storage should be on the system in proportion to renewable energy development, according to the consultant.

This event offers valuable lessons for regional utility stakeholders, particularly their capacity planning divisions. Over 100GW of renewable energy capacity is planned to be built across the GCC states before 2030, excluding those catering to private clients, with certain developments and projects looking to be powered 100% by renewable energy by 2030.

The Iberian story shows there are as many potential solutions or measures, with none offering zero risk, to address potential points of failure in today’s electricity system, which has been undergoing major re-engineering works to fit the 2030 net-zero scenario.

It is also worth mentioning that certain jurisdictions in the Gulf and broader Middle East and North Africa region regularly suffer from power outages in the summer, mainly due to rising temperatures and underinvestment in electricity generation and distribution networks, and notwithstanding a very negligible amount of renewable power on their grids.

  • Houthi truce collapse widens Gulf risk map

    15 July 2026

    Register for MEED’s 14-day trial access 

    The Houthis’ declaration ending the de facto truce with Saudi Arabia has significantly increased the likelihood of renewed attacks on Red Sea shipping and regional infrastructure, broadening the threat environment beyond the Strait of Hormuz.

    S&P Global Market Intelligence says the 13 July exchange is best understood as a potential widening of the renewed US-Iran escalation cycle into the Yemen and Red Sea theatres.

    Houthi claims that Saudi Arabia was responsible for a strike on Sanaa International airport have not been independently confirmed. Saudi Arabia had not formally commented at the time the analysis was written.

    The Yemeni militant group is likely to use the incident as a trigger that allows it to justify renewed military action while aligning with Iran’s wider effort to impose costs on US and Gulf interests, according to the research firm.

    The decision to declare an end to de-escalation with Riyadh materially increases the likelihood of further missile and unmanned aerial vehicle (UAV) activity against infrastructure near the Yemen-Saudi border, as well as renewed pressure on maritime routes in the Red Sea and Bab Al-Mandab.

    Aviation exposure

    The resumption of direct hostilities broadens the range of vessels and ports likely to be subject to Houthi targeting, and presents severe risk to airports and stationary aircraft, S&P Global Market Intelligence says.

    While the Houthis would probably not intentionally down civilian aircraft, there is a significant risk to aircraft in flight, particularly at lower altitudes close to airports, due to incoming UAVs and missiles and interceptor activity.

    The broader risk is to regional logistics rather than any single target set, the analysis says.

    If escalation around the Strait of Hormuz coincides with renewed Houthi activity in the southern Red Sea, Bab Al-Mandab and the Gulf of Aden, commercial operators face a more complex dual-chokepoint environment, with the added likelihood that the Houthis will seek to target Hormuz bypass infrastructure across the Gulf.

    That would raise the likelihood of shipping delays, higher insurance costs, more conservative routing decisions and greater interest in alternative corridors or bypass routes.

    Saudi Downtown Company, a wholly owned subsidiary of the Public Investment Fund (PIF), has awarded a contract for infrastructure works in downtown Al-Khobar.

    The contract was awarded to local contractor Ansab General Contracting Company.

    The scope of work includes the design and development of overall infrastructure, road networks and street lighting for the downtown Al-Khobar project.

    Saudi Downtown Company was officially launched in 2022 by Saudi Crown Prince Mohammed Bin Salman Bin Abdulaziz Al-Saud, who is also chairman of PIF.

    At the time, the company announced plans to develop downtown areas in 12 cities across the kingdom: Medina, Al-Khobar, Al-Ahsa, Buraidah, Najran, Jizan, Hail, Al-Baha, Arar, Taif, Dumat Al-Jandal and Tabuk.

  • Saudi Arabia opens third round of gas-fired IPPs

    15 July 2026

    Register for MEED’s 14-day trial access 

    Principal buyer Saudi Power Procurement Company (SPPC) has opened the qualification process for the third round of conventional independent power projects (IPPs) using combined-cycle gas turbine (CCGT) technology.

    The round is being tendered under the supervision of the Ministry of Energy. Each plant will be built with provision for carbon capture unit readiness, allowing the technology to be deployed at a later stage.

    Each project will be developed on a build-own-operate (BOO) basis, with the winning consortium taking 100% equity in a special purpose vehicle (SPV) set up to develop and operate the plant.

    Each SPV will sign a power purchase agreement with SPPC, which is licensed by the Saudi Electricity Regulatory Authority (SERA) to prepare preliminary studies, tender and award IPPs, and purchase electricity from energy projects in the kingdom.

    The programme forms part of Saudi Arabia’s Circular Carbon Economy approach, which underpins the energy sector element of the Vision 2030 strategy. Riyadh is displacing liquid fuels with natural gas in power generation to cut emissions intensity, while designing new plants so that carbon capture equipment can be retrofitted in support of national emissions targets.

    In April, Acwa and Saudi Energy (formerly Saudi Electricity Company) signed a 31-year power purchase agreement (PPA) with SPPC for the Rabigh 2 IPP expansion.

    The project involves the development of a CCGT plant in the Mecca region. It will have a total capacity of 2,313.5MW.

    The contract is valued at SR11.5bn ($3.07bn), the companies said in separate stock exchange filings.

  • Dubai selects contractor for Al-Maktoum airport people mover

    15 July 2026

     

    Register for MEED’s 14-day trial access 

    Dubai Aviation Engineering Projects (DAEP) has selected a contractor to deliver the automated people-mover system as part of the first phase of the $35bn expansion of Al-Maktoum International airport.

    A team of Japan’s Mitsubishi Corporation and Indian contractor Larsen & Toubro is the selected contractor.

    The automated people-mover system will serve as a critical facility for operations at Al-Maktoum International airport. The system will run under the apron of the entire airfield and the airport’s terminals. It will consist of multiple tracks, taking passengers from the terminals to the concourses.

    Four underground stations will be built as part of the first phase. The overall plan includes 14 stations across the airport.

    The firms submitted the bids for the project in July last year, as MEED exclusively reported.

    The contract is the latest in a series of awards signed by DAEP recently. DAEP has awarded contracts valued at about AED13bn, with construction works currently under way on several airport packages.

    These include enabling works, the second runway, and the initial structural foundations for passenger terminals and gates.

    Upcoming awards

    In June, DAEP said that it will award contracts worth over AED55bn ($15bn) by the end of this year for construction works at Al-Maktoum International airport.

    The projects slated for contract awards include the substructure works for the Western Passenger Terminal, the fourth aircraft concourse building and the baggage handling system, in addition to the superstructure works for the Western Passenger Terminal and the first, second and third aircraft concourses.

    The packages also encompass long-span structural frameworks for buildings covering about 1.5 million square metres (sq m), infrastructure works for the southern airfield area, and power generation and district cooling plants supporting the construction programme.

    The award of the facade and roofing packages is also planned for this year.

    Construction progress

    In May last year, MEED exclusively reported that DAEP had awarded a AED1bn ($272m) deal to UAE firm Binladin Contracting Group to construct the second runway at the airport.

    The enabling works on the terminal were awarded to Abu Dhabi-based Tristar E&C.

    Construction on the project’s first phase is expected to be completed by 2032.

    Construction on substructure works began in November last year, when DAEP formally selected a contractor to deliver the package.

    The government approved the updated designs and timelines for its largest construction project in April 2024.

    In a statement, the authorities said the plan is for all operations from Dubai International airport to be transferred to Al-Maktoum International within 10 years.

    According to an official description on DAEP’s website, the expanded airport’s West Terminal will be a seven-level, 800,000 sq m facility with an annual capacity of 45 million passengers.

    It will be the second of three terminals at Al-Maktoum International airport.

    In September 2024, MEED exclusively reported that a team comprising Austria’s Coop Himmelb(l)au and Lebanon’s Dar Al-Handasah had been confirmed as the lead masterplanning and design consultants on the expansion of Al-Maktoum airport.

    The airport’s construction is planned to be undertaken in three phases. The airport will cover an area of 70 square kilometres south of Dubai and will have five parallel runways and 430 aircraft gates.

    It will be five times the size of the existing Dubai International airport and will have the world’s largest passenger-handling capacity of 260 million passengers a year. For cargo, it will have the capacity to handle 12 million tonnes a year.

    Beijing-headquartered China State Construction Engineering Corporation (CSCEC) has won a contract to build the permanent headquarters of the Kuwait Direct Investment Promotion Authority (KDIPA).

    The contract covers the construction of a 275-metre, 55-storey office tower located in Kuwait City’s Sharq district. The project is expected to be completed by 2028.

    According to results published on the Kuwait Central Agency for Public Tenders (Capt) website, the firm initially submitted a bid of $233m, as MEED reported in January. The tender was issued on 19 October 2025 and bids were submitted on 18 November, MEED reported.

    The contract is the latest in a series of high-profile projects signed by CSCEC in the GCC region this year. Last month, it won a contract to deliver the Janadriyah cultural district at Qiddiya entertainment city on the outskirts of Riyadh. The contract was awarded by gigaproject developer Qiddiya Investment Company (QIC).

    The scope covers the construction of six structures, including a heritage building, a gateway hotel, a wadi hotel, a creative hub, a community centre and an open-air market.

    In June, MEED exclusively reported that QIC had awarded CSCEC a contract to build a new transport hub at Qiddiya entertainment city.

    The project is located within the resort core zone of the development.

    Kuwait market overview

    UK analytics firm GlobalData expects Kuwait’s construction industry to average annual growth of 4.9% in 2026-29, supported by government investment in renewable energy and transport infrastructure.

    In September 2025, Kuwait’s government allocated KD1.3bn ($4.2bn) for 141 projects, as part of its capital spending during the fiscal year 2025-26. This allocation was intended for 162 current projects and 17 new projects.

    According to government data, as of September 2025, the country had around 300 active projects, valued at about KD35.3bn ($115bn), with large infrastructure projects making up nearly half of that total.
