Decarbonising the global energy grid

3 May 2024

As the effort to tackle the climate crisis continues, global demand for renewable energy has been increasing. Unfortunately, the windiest and sunniest parts of the world are not necessarily where the need for energy is highest. This is where transmission plays a big role, linking energy generation to energy use as a product of global interconnection, and diversifying production from renewable sources to create a steadier supply of clean power. 

Transporting energy across vast distances is not easy though. From the regulatory complexities of navigating cross-border infrastructure projects to the high costs of financing and the need for long-term planning and advanced technical capabilities, the challenges involved in successfully deploying long-distance transmission projects are varied. Overcoming these challenges is not a single party affair, but requires close collaboration across government, industry and non-governmental organisations. 

We conducted a study with nearly 600 industry experts from across the world who highlighted the pressing need for co-ordinated global action to rapidly develop grid infrastructure. Integrating renewable energy into existing grids was cited by participants as one of the most significant barriers to achieving net-zero objectives, alongside supply chain vulnerabilities and ability to access the required capital.

Multiple challenges

From a technical standpoint, there are multiple considerations when implementing cross-border interconnections. Regions can operate using different technical parameters, such as different voltages or frequencies. Even within the same country, interregional variations can create bottlenecks. Adopting regional or international grid codes could mitigate these issues.

Further challenges emerge when we take trading into account. This is where regulation can act as an enabler, facilitating the flow of electricity between countries. The European Union’s efforts to co-ordinate the design of its member state’s energy markets enables an increasingly smooth transmission of energy across the continent. Alongside this, existing infrastructure is outdated, requiring significant upfront investment to upgrade. Clarity on regulatory requirements and more transparency around plans for grid buildout, derisk funding for capital-intensive mega projects.

Coordinated action is vital for the transfer of energy across borders and access to renewable sources of energy

Positive benefits

Despite these challenges, the upside must be stressed. Integrating power systems across borders has many positive societal benefits, decreasing costs and hence energy bills through economies of scale, increasing energy security and lowering the environmental impact of operations. On the latter more specifically, larger power systems are able to integrate higher shares of variable renewables. Globally, the sun is always shining and the wind blowing somewhere. 

A common element, therefore, emerges: the need for increased cross-border co‑ordination. Whether it is bilateral, multi-lateral or unified, different models of inter-jurisdictional arrangements are needed for large-scale projects to support global energy interconnections. Our Xlinks project, which is using high-voltage direct current (HVDC) for transmission, is a standout example. 

Such projects represent what is needed more in the world, the combination of infrastructure and renewable power across borders, bringing together the public and private sectors for energy security, supply and affordability in an environmentally friendly way. Transporting clean energy using HDVC cables is a crucial step in powering a net-zero and equitable future, and more of this is needed to aid the transition to lower-carbon and prosperous economies. 

Political, technical and market hurdles can be overcome through collaboration and partnerships. Leveraging the collective expertise and resources of governments, regulators and the private sector can help ensure interconnections are developed quickly enough to support the energy transition. Grid buildout takes time. We have the resources required to meet ambitions, but stopping now is not viable. We must continue planning, building and maintaining large-scale infrastructure projects to meet the rising demand.

Coordinated action is vital for the transfer of energy across borders and access to renewable sources of energy. This was the message from Cop28 and the UAE Consensus: to help progress and secure a cleaner, brighter future for us all, we must break down barriers and come together.

  • Qatar’s new $8bn investment spices up global LNG race

    13 March 2026

     

    In the midst of the conflict between Iran and the US and Israel, which has spilled over into the GCC region, QatarEnergy has temporarily halted production of liquefied natural gas (LNG) in the country and declared force majeure on LNG shipments after its energy assets came under attack.

    When the fog of war clears, however, and the Strait of Hormuz reopens to oil and gas flows, the global economy will look to QatarEnergy to swiftly restore regular LNG cargoes in order to bring gas prices down from record highs.

    Beyond that short-term role, the recent $8bn investment the Qatari giant has committed to building two new LNG processing trains will also cement its position as a reliable long-term supplier, while further intensifying the race among global LNG producers to carve out larger market shares in an increasingly gas-hungry world.

    North Field West – a game changer

    The state-owned company has progressed from the front-end engineering and design (feed) phase to the engineering, procurement and construction (EPC) stage of its North Field West LNG project at pace.

    It awarded the main EPC contract for the scheme – covering two LNG processing trains with a total capacity of 16 million tonnes a year (t/y) – to a joint venture comprising France’s Technip Energies, Greece/Lebanon-based Consolidated Contractors Company (CCC) and Gulf Asia Contracting on 25 February.

    The contract, estimated to be worth $8bn, was awarded just a month after Japan-based Chiyoda Corporation won the project’s feed contract.

    Such a short interval between the feed and EPC phases for a project as large as North Field West LNG would typically be considered improbable. Industry sources suggest QatarEnergy may have been in discussions with Chiyoda and the Technip Energies-CCC consortium for at least a year regarding the feed and EPC contracts, respectively – particularly given the two-year gap between the project’s announcement in February 2024 and the start of the EPC phase.

    Chiyoda, Technip Energies and CCC are also involved in the first two phases of QatarEnergy’s $40bn North Field LNG expansion project. A consortium of Chiyoda and Technip Energies is executing EPC works on the North Field East project, which involves the construction of four LNG trains with a combined capacity of 32 million t/y, following the award of a $13bn contract in February 2021. Meanwhile, a Technip Energies-CCC consortium is carrying out EPC works on two 7.8 million t/y LNG trains as part of the North Field South project, having secured a $10bn contract in May 2023.

    More significant, however, is the speed with which QatarEnergy is advancing its strategic objective of reaching a total LNG production capacity of 142 million t/y by the end of the decade, from 77.5 million t/y at present.

    With all three phases of the North Field LNG expansion programme now under EPC execution – and North Field East scheduled for commissioning later this year – QatarEnergy appears firmly on track to become one of the world’s largest LNG suppliers over the long term, reinforcing Qatar’s economic future in the process.

    US domination

    While QatarEnergy is on course to increase its LNG production capacity by 83% by 2030 through the overall North Field LNG expansion programme, it is still some way behind the US, which is set to account for over half of the total global LNG liquefaction projects by 2030.

    There are 40 new-build and expansion LNG liquefaction projects planned or under way in the US, according to UK analytics firm GlobalData. Among these, two projects stand out.

    The first is the Rio Grande LNG production project, being developed by NextDecade in Texas, on the US Gulf of Mexico coast. Up to 10 processing trains are planned for the complex, the first three of which are in the EPC phase.

    NextDecade achieved the final investment decision on the fourth and fifth trains at the facility, estimated to cost $6.7bn each, in September and October last year. The company has awarded EPC contracts to build all five trains at the Rio Grande facility to US-based Bechtel.

    On the investments front, the overseas-focused energy investment vehicle of Abu Dhabi National Oil Company (Adnoc), XRG, acquired an indirect 11.7% stake in the first phase of the project from Global Infrastructure Partners (GIP), part of US asset manager BlackRock, in September last year. In February 2026, XRG entered into another transaction with GIP to raise its overall participation in the Rio Grande LNG project by acquiring additional 7.6% equity interests in trains four and five of the scheme.

    Additionally, as part of that transaction, another Adnoc Group subsidiary, Adnoc Trading, entered into a 20-year offtake agreement with NextDecade last year to purchase 1.9 million t/y of LNG from Rio Grande train four, on a free-on-board basis at a Henry Hub-indexed price. France’s TotalEnergies and Saudi Aramco are the other LNG offtakers for train four.

    Separately, the Commonwealth LNG facility in the US state of Louisiana has also received backing from Abu Dhabi. Expected to start operations in 2030, the facility is designed to produce up to 9.5 million metric t/y of LNG.

    Commonwealth LNG is a project of US-based alternative asset manager Kimmeridge Energy Management Company and Abu Dhabi’s sovereign wealth fund Mubadala Investment Company through their joint venture Caturus.

    Caturus was formed in August 2025 when Kimmeridge announced a rebranding that saw Commonwealth LNG and Kimmeridge’s upstream operations combined under a new integrated platform. At the same time, Mubadala acquired a 24.1% equity stake in Caturus, providing financial backing for the new entity to proceed with the Commonwealth LNG project.

    Also in August, Caturus awarded Technip Energies the contract for EPC works on the Commonwealth LNG project. The French contractor had previously performed the project’s feed work.

    Moreover, Aramco subsidiary Aramco Trading signed a 20-year agreement to buy 1 million metric t/y of LNG from the Commonwealth LNG facility in February, increasing offtake deals secured by Caturus to cover 8 million metric t/y of the project’s total planned output capacity.

    Positive outlook

    The growth in LNG production capacity in the US, as well as in wider North America, is driven by several factors, including abundant natural gas reserves, the shale gas revolution and advancements in hydraulic fracturing and horizontal drilling.

    While it might be a challenge for QatarEnergy to compete with US players in combined liquefaction capacity, its strength and success will lie in clinching long-term offtake deals with customers in Asia, where the bulk of global LNG demand growth is expected.

  • Bahrain opens bids for first solar IPP project

    13 March 2026

    Two companies have made offers for a contract to develop Bahrain’s first solar photovoltaic (PV) independent power project (IPP).

    Bahrain’s Electricity & Water Authority (EWA) opened bids for the Bilaj Al-Jazayer solar IPP project on 12 March.

    The bidders include Saudi Arabia’s Acwa, formerly Acwa Power, and UAE-headquartered Yellow Door Energy.

    The 150 MWac Bilaj Al-Jazayer solar IPP project will be Bahrain’s first grid-connected solar PV power plant developed under a public-private partnership (PPP) framework on a build-own-operate basis. It will be delivered as a long-term concession and is intended to come online by 2027.

    The proposed site covers more than 1 square kilometre, with the private sector responsible for end-to-end development, including financing, design, construction and operation.

    Last August, EWA held a market consultation event during which it outlined plans for the country’s first solar PV IPP. The main contract was then tendered in October.

    EWA said Yellow Door Energy’s proposal was “accepted with conditions”, but did not disclose further details.

    The local KPMG Fakhro is the financial consultant, the US’ WSP Parsons Brinckerhoff is the technical consultant, and the UK’s Trowers & Hamlins is the legal consultant.

    Bahrain’s clean energy targets, as set by its national plans, include 20% renewables by 2035, and net-zero emissions by 2060.

  • DP World sees Red Sea port volumes rising as Hormuz shuts

    13 March 2026

    Register for MEED’s 14-day trial access 

    Dubai-based ports operator DP World is preparing for higher throughput at its Red Sea terminals as the Iran conflict approaches its second week, CEO Yuvraj Narayan said on Thursday.

    With the Strait of Hormuz effectively closed and tanker attacks escalating, shipping movements into Gulf ports have fallen.

    The disruption began after US and Israeli strikes on Iran, rattling energy and freight markets and cutting access through what is widely seen as the world’s most critical oil corridor.

    Since most major Gulf ports rely on the narrow Strait of Hormuz, the shutdown is weighing on regional trade flows.

    Narayan said Jebel Ali, DP World’s main hub in Dubai, has not suffered any infrastructure damage and is operating normally, but inbound vessel arrivals are down. Some cargo is still moving through terminals on the eastern side of the strait, he added.

    Ports in the UAE that sit outside Hormuz have limited headroom to absorb the shortfall. Khorfakkan can handle about 5 million 20-foot equivalent units (TEUs) and Fujairah under 1 million TEUs, which Narayan indicated would not be enough to offset lost volume from Jebel Ali or Abu Dhabi’s Khalifa Port.

    Jebel Ali alone processed 15.6 million TEUs last year, out of DP World’s 56.1 million TEUs globally.

    DP World is rolling out rerouting options and other operational measures to keep supply chains moving. Narayan said the company’s Red Sea assets, such as Jeddah in Saudi Arabia and Sokhna in Egypt, are likely to see increased traffic, though he did not quantify the additional volumes or specify cargo types.

    He cautioned that logistical and security risks remain elevated.

    Earlier this week, DP World announced record financial results for 2025, with revenue up 22% to $24.4bn and adjusted earnings before interest, taxes, depreciation and amortisation (Ebitda) up 18% to $6.4bn, delivering a 26.3% margin, as MEED reported.

    DP World said that this performance was driven by strong momentum across its ports and terminals and logistics business.

    The group’s gross throughput rose 5.8% to 93.4 million TEUs.

    Profit for the year increased 32.2% to $1.96bn, and operating cash flow grew 14% to $6.3bn.

    Return on capital employed increased to 9.9% in 2025, up from 8.9% in 2024, reflecting stronger earnings despite ongoing geopolitical and trade uncertainty.

  • Frontrunner emerges for Saudi sewage treatment project

    13 March 2026

     

    A consortium led by China’s Jiangsu United Water Technology has emerged as the frontrunner for a contract to build and upgrade two sewage treatment plants in Saudi Arabia, according to sources.

    The contract covers the North Western A Cluster Sewage Treatment Plants Package 11 (LTOM11), part of the next phase of National Water Company’s (NWC) long-term operations and maintenance (LTOM) sewage treatment programme.

    The consortium comprising United Water, Prosus Energy (UAE) and Armada Holding (Saudi Arabia) offered “the lowest tariff” for the project, sources told MEED.

    It is understood that Turkey’s Kuzu has made the next-lowest bid.

    The development, estimated to cost about $211m, will have a combined capacity of about 440,000 cubic metres a day (cm/d).

    In February, MEED exclusively reported that six bidders were competing for the contract.

    The other companies that have submitted proposals include:

    • Alkhorayef Water & Power Technologies (Saudi Arabia)
    • Civil Works Company (Saudi Arabia)
    • VA Tech Wabag (India)
    • Aguas de Valencia (Spain)

    LTOM11, also known as the North Western A Cluster, forms part of the second phase of NWC’s rehabilitation of sewage treatment plants programme.

    The scheme is being procured on an engineering, procurement and construction (EPC) basis with a long-term operations component.

    The main contract was tendered last year, with an award initially expected by the end of 2025.

    It is now understood that NWC is preparing to offer the main contract in the second quarter.

    As previously reported, Saudi Arabia’s NWC is also evaluating five bids for package 12 of its long-term operations and maintenance (LTOM12) sewage treatment programme.

    Known as the North Western B Cluster, LTOM12 forms part of the second phase of NWC’s rehabilitation of sewage treatment plants programme.

    In January, the same United Water-led consortium won the main contract for the Northern Cluster Sewage Treatment Plants Package 10 (LTOM10).

    That project includes the rehabilitation and operation of nine sewage treatment plants located across the Hail, Qassim, Al-Jouf and Northern Borders provinces

    NWC is also preparing to tender a contract for the construction of 10 sewage treatment plants as part of package 14 of the programme.

    The final details of the Eastern A Cluster (LTOM14) package are being finalised, with a tender likely to be issued in March or April, sources told MEED.

  • Medina tenders Sikkah Al-Hadid PPP project

    13 March 2026

    Saudi entities including Al-Madinah Regional Municipality, in collaboration with the Ministry of Municipalities & Housing and the National Centre for Privatisation & PPP (NCP), have floated a request for proposal (RFP) notice for the development of the Sikkah Al-Hadid project.

    The project will be procured through build-own-operate-transfer contracts with a 50-year duration, using a public-private partnership (PPP) model.

    The deadline for bid submission is 23 June.

    The project will be located to the west of Medina on an 84,657-square-metre (sq m) site. 

    It includes a four-storey medical centre with a capacity of up to 200 beds and a shopping mall offering retail, food and beverage, and other entertainment facilities.

    In January last year, NCP asked firms to express their interest and prequalify for a contract to develop two mixed-use developments in Medina, which included the Sikkah Al-Hadid project and the Dhul Hulaifah project.

    The Dhul Hulaifah project will be built on a 30,112 sq m site located six kilometres from the Prophet’s Mosque. 

    The development will consist of a four-star hotel integrated with retail and healthcare facilities.

    MEED previously reported that Saudi Arabia had announced a P&PPP pipeline comprising 200 projects across 16 sectors.

    This pipeline aims to attract local and international investors and ensure their readiness to participate in the schemes tendered to the market.

    The initiative comes as the kingdom strives to increase the attractiveness of its economy and raise the private sector’s contribution to GDP.
