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."
