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.

  • Qatari Diar unveils $30bn Egypt project masterplan

    21 July 2026

    Qatari Diar, the real estate arm of the Qatar Investment Authority, has announced the masterplan for its $30bn Alam Al-Roum project on Egypt’s north coast.

    The masterplan was developed by US-based architectural firm Skidmore, Owings & Merrill.

    The master-planning team also includes US-based landscape architecture firm SWA; UK-headquartered marina design and operations consultant Marina Projects; and French transport and traffic engineering consultant Setec.

    The development will cover more than 20 million square metres and include 7.2 kilometres of private beachfront on the Mediterranean Sea.

    The site is about 20 minutes from Marsa Matrouh and 50 minutes from Ras El-Hekma.

    According to a statement, the project includes $3.5bn in direct cash investment and is designed as an integrated, year-round Mediterranean destination.

    Alam Al-Roum expands Qatari Diar Egypt’s portfolio, which includes CityGate, New Giza and The St Regis Cairo.

    Qatari Diar and Egypt’s New Urban Communities Authority signed the project agreement for Alam Al-Roum in November 2025.

    The estimated value of the deal to Egypt is $7.5bn. Under the agreement, Cairo will receive an upfront payment of $3.5bn by late December 2025 for the initial land purchase and is expected to receive an in-kind stake in the project, estimated to be worth $1.8bn.

    Qatari Diar’s broader investment plans for the area include spending up to $26.2bn in addition to the $3.5bn already allocated for the land purchase.

  • Contractors submit final offers for Global Sports Tower

    21 July 2026

     

    Contractors submitted their last and final offers in the first week of July for the main construction contract for the Global Sports Tower, located in the Athletics District of the Sports Boulevard development in Riyadh.

    The Sports Boulevard Foundation issued the tender for the main works contract on 31 July last year.

    The 130-metre-tall Global Sports Tower will cover an area of 84,000 square metres (sq m) and include more than 30 sports facilities.

    The tower will feature the world’s tallest indoor climbing wall, at 98 metres, and a 250-metre running track.

    Saudi Arabia’s Sports Boulevard Foundation also received bids on 10 June for a contract covering project management consultancy (PMC) services for the Global Sports Tower, as MEED reported.

    MEED reported in May 2025 that design work on the tower had been completed. Saudi Arabia’s Crown Prince Mohammed Bin Salman Bin Abdulaziz Al-Saud approved the designs in 2024.

    The Sports Boulevard development runs across Riyadh from east to west and, once complete, is set to be the world’s longest park, spanning more than 135 kilometres.

    The development will feature several districts, including Wadi Hanifah, the Arts District, Urban Wadi, the Entertainment District, the Athletics District and the Eco District, as well as Sands Sports Park.

    The large-scale project aims to transform central Riyadh – currently dominated by major highways – into a recreational corridor.

    Sports Boulevard, which will feature 4.4 million sq m of public realm and landmark buildings, will also be home to the Centre for Cinematic Arts and a 2,000-seat amphitheatre.

    The development will provide more than 2.3 million sq m of mixed-use commercial, residential and retail assets, along with sports facilities around the park, which will be known as Linear Park.

  • Consultants submit bids for Saudi Arabia’s GCC rail link

    20 July 2026

     

    Consultants submitted proposals on 14 July for a contract to provide design consultancy services for the Saudi Arabian section of the GCC railway network, which is intended to link all six member states.

    Saudi Arabia Railways (SAR) issued the tender on 7 May, MEED previously reported.

    The tender covers the concept, preliminary and issued for construction design stages. SAR requires the selected consultant to review, update and complete the existing preliminary design.

    The consultants who submitted bids include: 

    • Atkins with Khatib & Alami
    • DeutscheBahn with ARX
    • Egis with Sener
    • Idom with Dal Al-Handasah
    • Systra

    Saudi Arabia’s section of the railway will start at Al-Khafji in the Eastern Province, near the border with Kuwait, and end at Al-Batha, on Saudi Arabia’s border with the UAE. The route length in Saudi Arabia will be about 672 kilometres (km).

    The railway will interface with the Kuwait National Rail Road (KNRR) project on the Kuwaiti side. Last year, MEED exclusively reported that the KNRR design contract was awarded to Turkiye’s Proyapi Muhendislik ve Musavirlik Anonim Sirketi.

    The KNRR forms part of the wider GCC rail network. GCC railway projects have gained renewed momentum since the six member states signed the Al-Ula Declaration in January 2021.

    In October last year, Qatar’s cabinet approved a draft agreement paving the way for a railway link between Qatar and Saudi Arabia as part of the GCC railway network.

    GCC railway line

    Under the overall plan, the railway will run from Kuwait, pass through Dammam in Saudi Arabia, reach Bahrain via a planned causeway, and continue from Dammam to Qatar, the UAE and, ultimately, Muscat via Sohar in Oman. The railway is reported to span about 2,186km in total.

    The route length within each member state is as follows: 684km in the UAE, 672km in Saudi Arabia, 306km in Oman, 283km in Qatar, 145km in Kuwait and 36km in Bahrain.

    The railway is designed for passenger trains travelling at 220km/h and freight trains operating at 80-120km/h.

    With high levels of project activity, governments in spending mode and renewed cooperation under the Al-Ula Declaration, the latest efforts to restart the GCC railway project may make more progress than previous attempts. If completed, the railway could prove transformational for a region that is globally connected but still divided by national borders.

  • Chinese firm wins Dubai drainage contract

    20 July 2026

    China State Construction Engineering Corporation (CSCEC) has announced it has won a contract to deliver a stormwater drainage pipeline package under Dubai Municipality’s Tasreef programme.

    The contract is for the TF-15-C2 stormwater drainage network project located along Umm Suqeim Road in the Al-Barsha and Al-Quoz areas of Dubai. 

    MEED exclusively revealed in May that the contractor had been selected for the engineering, procurement and construction (EPC) contract. The project is estimated to cost $162m.

    The scope of work includes the construction of about 20 kilometres of new stormwater pipelines, together with associated inspection and intake manholes. The project is located west of the Dubai Canal and will connect the Al-Quoz 3 and Al-Quoz 4 industrial areas with Al-Quoz 1.

    It is being delivered as part of Dubai’s Tasreef strategic plan, which supports the Dubai 2040 Urban Master Plan. Once completed, the new drainage infrastructure is expected to improve the emirate’s stormwater network, increase flood protection and enhance the resilience of Dubai’s infrastructure.

    In February, the municipality confirmed it had awarded contracts for five new projects under phase two of the programme to expand and strengthen Dubai’s stormwater drainage network.

    These include a separate contract awarded to CSCEC for the TF-11-C1 stormwater drainage project in the Dubailand area.

    Also in February, Dubai Municipality invited consultants to qualify for a contract to supervise construction on the TF-15-C2 stormwater drainage projects along with two other projects (TF-13-C1 and TF-16-C1) under the Tasreef programme.

    According to a source, a consultant has yet to be appointed.

    TF-16-C1 involves upgrading and rehabilitating the stormwater system east of the Dubai Canal, while TF-13-C1 involves building a water pipeline stormwater drainage system at Al-Marmoum, Al-Qudra and Al-Yalayis 2 & 3.

    Bids are currently under evaluation for the EPC contracts for both projects.
