GCC battery storage pipeline hits over 55GWh

The battery energy storage system (bess) plant project pipeline in the GCC region – mainly in Saudi Arabia and the UAE – has reached 55.4 gigawatt-hours (GWh) of estimated rated capacity.

Data from MEED and regional projects tracker MEED Projects indicates that schemes with a total capacity of about 21.7GWh are under construction, primarily in Saudi Arabia, while bess plants in the pre-execution phase have an estimated cumulative rated capacity of 33.8GWh.

This substantial pipeline has been built over the past two to three years, when a total of 3.9GWh of capacity was built in Saudi Arabia through the 1.3GWh Red Sea multi-utility project and the recently completed 2.6GWh battery energy storage plant by Saudi Arabia's National Grid.

"The main energy storage driver across the GCC region is the rapid deployment of low-cost solar power to meet growing demand," notes Marek Kubik, a Saudi Arabia-based industry expert. 

"As photovoltaic (PV) produces power only in the day and is a non-synchronous form of power, this brings with it certain balancing, ramping and stability challenges. 

"Bess is needed for storing and shifting solar power from day to night, to reduce congestion and improve utilisation on the transmission system, as well as providing stability services to support stable grid operations," says Kubik.

Capacity ramp-up

With an estimated 775MW/3.9GWh of deployed capacity at the end of 2024, the GCC region accounts for a small proportion of the global deployment of about 160GW or 363GWh, according to the Volta Foundation.

The global not-for-profit group said global bess installations last year accounted for more than 45% of the total cumulative global capacity.

The region is poised to catch up with the rest of the world, however. Saudi Arabia's Bisha bess plant is one of 17 projects globally with a capacity of over 1GWh that entered operations in 2024.

A total of 21.7GWh of capacity is under construction in Saudi Arabia and is expected to be completed by the end of the year, with more under way.

Such growth will likely overtake the 55% year-on-year growth observed by the Volta Foundation.

The GCC region’s first major bess independent power producer (IPP) scheme was integrated into Red Sea Global’s multi-utility package in Saudi Arabia.

Developed by Saudi utility developer Acwa Power and built by China’s Huawei Digital, the 1,300 megawatt-hour (MWh) facility caters to the 28,000 square-kilometre “regenerative” tourism project on the west coast of the kingdom, which is being powered 100% by clean energy.

A bess facility with a capacity of 760MWh is also included in a similar multi-utility package for Red Sea Global’s sister development, Amaala.

The 2.6GWh Bisha represents an important milestone, ushering the kingdom onto the list of the world's top locations for lithium iron phosphate (LFP)-based bess.

So far, every utility or grid operator in the GCC, Morocco and Jordan plans to procure or has started to procure bess capacity independently, to balance their grid as electricity demand and renewable energy capacity increase, or as part of a solar power plant scheme.

In the absence of viable hydropower capacity, which is the main energy storage capacity in non-water-scarce regions, or thermal energy storage systems like molten salt, bess is emerging as the best alternative to enhance the flexibility of existing energy or electricity systems as sources increasingly diversify.

Abu Dhabi state utility Emirates Water & Electricity Company (Ewec) received 93 expressions of interest and prequalified more than two dozen companies to bid individually or as members of consortiums for its first pair of bess plants, which will have a capacity of up to 800MWh.

In January, Ewec and Abu Dhabi Future Energy Company (Masdar) announced a project that aims to convert solar power into base load capacity by coupling a 5GW solar PV plant with a 19GWh battery energy storage facility in Abu Dhabi.

Falling lithium prices and oversupply 

The need for grid flexibility and a steep fall in the price of lithium – the main raw material for the dominant battery technology – has helped utilities to move forward with their plans to procure bess, which was considered cost-prohibitive until a year ago.

According to a BloombergNEF (BNEF) report in December, lithium-ion battery pack prices dropped 20% from 2023, to a record-low of $115 a kilowatt-hour.

Factors driving the decline include cell manufacturing overcapacity, economies of scale, low metal and component prices, the adoption of lower-cost LFP batteries and a slowdown in electric vehicle (EV) sales growth.

In the past two years, battery manufacturers have expanded production capacity in anticipation of surging demand for batteries in the EV and stationary storage sectors.

According to BNEF, overcapacity is rife, with 3.1 terawatt-hours of fully commissioned battery-cell manufacturing capacity globally, which is more than 2.5 times the annual demand for lithium-ion batteries in 2024.

It added that while demand in all sectors saw year-on-year growth, the EV market – the biggest demand driver for batteries – grew more slowly than in recent years.

In contrast, stationary storage markets have taken off, with strong competition in cell and system providers, especially in China.

Completed and under-construction bess plants in the GCC are all supplied by Chinese battery cell and system providers. BYD and Sungow account for 59% and 36% of completed and under-construction battery energy storage plants in Saudi Arabia, respectively, while Huawei accounts for the rest.

Contemporary Amperex Technology Company (CATL) will be supplying the battery cell and systems for Abu Dhabi's round-the-clock 1GW solar project.

Prices are expected to fall further, which will likely accelerate GCC deployments.

Some experts predict the prices could drop to as low as $50/kWh-$25/kWh and, at best, to as low as $10/kWh by the end of the decade, subject to extrapolating current battery learning rates of about 25% for every doubling of capacity. 

Longer-duration battery cells

Despite their expected widespread deployment, there are concerns that batteries providing up to six hours of storage may not be sufficient to address the peak electricity demand in most GCC states.

Demand in the GCC states peaks between 6pm and 6am, when air-conditioning systems, street lighting and other home appliances are turned on, and where there is little wind capacity to supply renewable power.  

Nevertheless, a staged approach to bess deployment is necessary to get to a fully net-renewable electricity system, says Kubik.

"Around the world, this is approached in a staged manner and bess of increasing duration is added over time, as the depth of renewable penetration increases," he says.

"The GCC has, to an extent, leapfrogged other markets by starting with four-hour to six-hour bess, but over time this need will grow to about eight- to 10-hours, which is enough to move to more or less a ‘baseload’ around-the-clock solar profile. As LFP costs continue to fall, longer-duration systems are rapidly becoming more economic."

  • Contractors prepare bids for Morocco power line

    2 November 2026

     

    Contractors are preparing bids for a 160-kilometre (km), 400kV transmission line linking Guercif and Fes East in Morocco, following a site visit on 1 October.

    The project is being developed by the Office National de l'Electricite et de l'Eau Potable (Onee) to connect the Saka solar photovoltaic power plant to the national electricity grid.

    According to sources, at least eight contractors attended the site visit last month, including:

    • Butec (Lebanon)
    • CEEC Northeast Electric No.2 (China)
    • Cegelec (France)
    • EPME Electric (Morocco)
    • Hideleco (Egypt)
    • Kec International (India)
    • PowerChina (China)
    • Transrail (India)

    The project comprises two lots. The first involves a 90km transmission line between Guercif and Taza, while the second covers a 70km section between Taza and Fes East.

    The scope of work includes the construction of tower foundations, installation of transmission supports and conductors, and associated high-voltage equipment. It also includes optical fibre cables for communications and monitoring, access roads and other supporting infrastructure.

    The tender was issued in September with bids originally due by 21 October. The deadline has now been extended to 25 November.

    The project is part of a wider programme by Onee to expand Morocco's electricity transmission network and accommodate additional renewable energy capacity.

    In June, the utility commissioned a 274km, 400kV transmission line linking Chemaia and Mediouna, near Casablanca.

    Onee plans to expand its high- and extra-high-voltage transmission network from more than 30,700km to 37,000km by 2030.

    In August, it approved a $26.4bn investment programme for the 2026-30 period, covering electricity and drinking water infrastructure.

    The programme has allocated about $21.9bn to electricity projects and $4.5bn to drinking water infrastructure, with about 72% of the investment to be financed by the private sector, according to Onee.

  • Adnoc Onshore allows more time for Bab gas cap well tie-in bids

    2 November 2026

     

    The onshore business of Abu Dhabi National Oil Company (Adnoc Onshore) has allowed contractors more time to prepare proposals for a project to tie in gas-producing and injection wells at the gas cap reservoirs of Abu Dhabi’s onshore Bab field.

    The well tie-in scope, estimated to be worth more than $800m, forms part of Adnoc Group’s wider integrated Bab gas cap development programme.

    The overall programme is being led and overseen by Adnoc Gas, another Adnoc Group subsidiary. Its central element is the construction of gas-processing infrastructure to handle incremental gas output expected from developing the Bab gas caps.

    Adnoc Onshore issued the main tender for engineering, procurement and construction (EPC) works on the project in late September, MEED previously reported.

    Contractors have been given until 16 November to submit technical bids for the project, according to sources. The previous deadline was 29 October.

    MEED previously reported that Adnoc Onshore issued an expressions of interest (EoI) notice for the Bab gas production and injector well tie-in project on 13 May, with contractors submitting responses by 20 May.

    The scope of work on the project covers the following:

    • Tie-in of 99 new wells from Bab gas cap reservoirs KH-2, SH-1 and LK-1 (60 gas producers and 39 gas injectors);
    • Installation of well gathering structures: 10 gas pads, six well bays and three virtual pads;
    • Installation of a gas gathering network and a gas injection network;
    • Rerouting of the LK-3 production from the existing trunkline in Remote Manifold Station 3 (RMS-3) to the project’s production trunkline, Bab Gas TL-2;
    • Demolition of the existing 10-inch trunkline from RMS-3 to onshore gas development phase one.

    In the EoI document, Adnoc Onshore said it intends to award the EPC contract in the last quarter of the year, with a 45-month duration of works.

    Bab gas cap project infrastructure

    As part of its 2030 upstream production increase goals, Adnoc Group is working to extract gas from four underdeveloped gas cap reservoirs at the Bab onshore field development – Thammama A, Thammama B, Thammama F and Thammama H.

    While the Thammama A, B and H reservoirs are estimated to collectively produce 1.45 billion cubic feet a day (cf/d) of gas, output from the Thammama F gas cap is expected to be at a rate of 396 million cf/d.

    Existing trains at the Habshan processing complex in Abu Dhabi will be unable to handle the new gas volumes. Therefore, Adnoc Gas is required to build new facilities to process an additional volume of up to 1.85 billion cf/d of raw gas.

    Adnoc Gas is planning to build a gas processing plant in the Bab area, about 170 kilometres from Abu Dhabi, along with associated pipeline networks and other ancillary units, as part of the broader Bab gas cap development project. It has divided the EPC scope of work on the project into four packages:

    • EPC package 1 – Main Bab gas cap plant
    • EPC package 2 – Early civil works
    • EPC package 3 – Pipelines
    • EPC package 4 – Non-process area works

    Abu Dhabi Securities Exchange-listed Adnoc Gas issued the tender for the main Bab gas cap plant on 25 June and set an initial deadline of 17 July for contractors to submit technical bids. The company then extended the technical bid submission deadline by four months, until 16 November, MEED previously reported.

    Following a reshuffle of the consortiums gearing up to bid for the main Bab gas plant EPC package, estimated to be worth more than $6bn, the following teams have formed to compete in the main contract tendering round:

    • Larsen & Toubro Energy Hydrocarbon (India) + Petrofac Emirates (UAE)
    • Technip Energies (France) + JGC Corporation (Japan) + Sinopec (China)
    • Tecnimont (Italy) + China Petroleum Engineering and Construction Corporation (CPECC)

    The other three packages of the Bab gas cap project are also in the main contract tendering stages.

    Prior to issuing the EoIs for the project packages, Adnoc Gas completed an early engagement process with contractors in September and October last year, as MEED previously reported.

    In December last year, Adnoc Gas awarded the front-end engineering and design (feed) works for the development project  to Australia-based consultancy Worley. The feed contract has a duration of more than 1.2 million man-hours, making it the largest-ever engineering job awarded by Adnoc Gas.

    Bab Gas Cap concession

    In addition to Adnoc Gas overseeing the main EPC tendering exercise for the gas processing plant, Abu Dhabi’s Supreme Council for Financial and Economic Affairs (SCFEA) awarded concession agreements in June for the development and production of the Bab gas cap reserve.

    Adnoc will hold the majority 60% participating interest in the concession. The remaining stakes will be held by France’s TotalEnergies (10%), the UK’s BP (10%), China National Petroleum Corporation International (8%), Japan Oil Development Company Onshore (5%), China ZhenHua Oil (4%) and Korea GS E&P (3%).

    According to the SCFEA, the Bab gas cap development and production concession represents the largest gas cap development project of its kind globally, the Abu Dhabi Media Office said in a report.

    A gas cap refers to the free natural gas that sits above an underlying oil reservoir – in this case, the Bab onshore oil field in Abu Dhabi.

    The project, operated by Adnoc Onshore, is expected to have a production capacity of approximately 1.5 billion cf/d of natural gas, equivalent to about 15% of Adnoc Gas’ total operational gas processing capacity.

  • Gulf ministers insist Hormuz is still essential

    2 November 2026

    Register for MEED’s 14-day trial access 

    Senior Gulf officials have rejected suggestions that new pipelines and rail links will allow the region to do without the Strait of Hormuz, arguing that the waterway will remain essential to the GCC and the global economy.

    Speaking at the Gateway Gulf investment forum in Manama on 1 November, GCC secretary-general Jasem Mohamed Albudaiwi said keeping the strait open is the responsibility of the international community, not of any one country or group of partners. "We hear some voices that maybe we should seek alternatives to Hormuz," he said. "Fine, we will get the pipelines. We will get the GCC railway. But that doesn't mean Hormuz is nobody's business."

    Albudaiwi called for the strait to remain open in line with international law, including the 1982 UN Convention on the Law of the Sea.

    Shipping through the strait has been severely restricted since the US and Israel launched strikes on Iran on 28 February and Iran retaliated with attacks on GCC states and commercial vessels.

    Bahrain's Finance & National Economy Minister, Sheikh Salman Bin Khalifa Al-Khalifa, said building redundancy makes sense, but treating the strait as dispensable does not. He said the waterway carries 30% of global liquefied natural gas (LNG) exports, 20% of aluminium exports and 30% of fertiliser exports. "Any thinking about the alternative of Hormuz, as in we won't need it, is illogical, because we will need it for the world economy," he said.

    UAE Economy & Tourism Minister Abdulla Bin Touq Al-Marri said that "Hormuz matters, and Hormuz will keep mattering", adding that an economy dependent on a single trade route is exposed if that route closes.

    Sheikh Salman said the crisis has compressed years of GCC customs negotiations into weeks. During the conflict, containers cleared at Jeddah with final destinations in Bahrain or Kuwait moved on without further checks, and the same applied to cargo routed through Salalah and Fujairah, he said. GCC ministers have since agreed to make these emergency measures permanent.

    He also cited Gulf Air operating out of Saudi airports for more than 40 days without a written agreement, and a $5bn swap between the UAE and Bahraini central banks to stabilise currencies.

    Bin Touq said the bloc should use 2027 and 2028 to push through reforms, including removing remaining customs barriers between member states.

    Albudaiwi said GCC leaders meeting in Jeddah on 28 April had tasked the secretariat with advancing water connectivity, expanding the GCC electricity grid, planning new logistics infrastructure including ports, accelerating the GCC railway and enhancing oil and gas pipeline links.

  • Bahrain’s Gateway Gulf brings $20bn of deals

    2 November 2026

    More than 110 announcements worth over $20bn will be made at the Gateway Gulf Investment Forum in Bahrain, according to the country's finance minister.

    "Over the next two days at Gateway Gulf, more than 110 announcements worth over $20bn will be made," Sheikh Salman Bin Khalifa Al-Khalifa, Finance & National Economy Minister, said at the opening of the forum's fourth edition on 1 November in Bahrain.

    He said the announcements will cover new partnerships, investments, projects and jobs. Sheikh Salman addressed an audience that included Bahrain's Crown Prince and Prime Minister, Prince Salman Bin Hamad Al-Khalifa.

    The minister said the region's economies have been "tested as never before" since the previous edition of the forum a year earlier.

    "In the face of unprecedented attacks, we did not waver," he said. He added that Bahrain has chosen to work more closely with its allies and partners to defend what it has built.

    Sheikh Salman said the Gulf economy has grown to $2.4tn in GDP. Non-oil sectors account for more than 86% of Bahrain's GDP and more than 77% across the Gulf, he said.

    He said Gulf banks hold more than $4tn in assets, while the region's sovereign wealth funds manage more than $5tn of investments. "These numbers describe a region that has chosen to build a more stable, a more prosperous future for its people," he said. "Bahrain is the gateway to that region."

    The minister said Bahrain is focusing on regulation, infrastructure and people to attract investment.

    He said the country has developed a regulatory framework over several decades that is "clear, modern and fast", allowing investors to commit with confidence.

    On infrastructure, he highlighted logistics, connectivity, digital networks and industrial land as areas where Bahrain is building the foundations for businesses to expand. He also named finance, logistics, tourism, manufacturing, technology and telecommunications, and oil and gas as the sectors into which he expects domestic, regional and international capital to flow.

    He said the investments will create jobs for young graduates and support the growth of family businesses.
