A snapshot of major global developments shows that the new scale of energy storage is now measured in gigawatt-hours. Australia, the United Arab Emirates, India, Chile, the Philippines, and the United States are home to some of the world's most significant projects, with capacities ranging from 1.4 GWh to 42 GWh.
The ranking allows us to understand not only which projects are leading in size, but also which models are starting to set trends: large solar complexes with batteries, standalone assets for grid backup, hybrid projects with continuous supply contracts, and platforms designed to support the electrification of demand.
1. Australia-Asia Power Link – Australia: 42 GWh
The top spot is held by the Australia-Asia Power Link, one of the world's most ambitious projects due to its scale, technical complexity, and its goal of exporting renewable energy.
The project envisions a large solar power plant in Australia's Northern Territory, accompanied by a storage system with a capacity of between 36 and 42 GWh. The electricity generated would be used for both local consumption and export to Singapore via a long-distance transmission infrastructure.
2. Al Azeezah BESS – United Arab Emirates: 19 GWh
Second place goes to Al Azeezah BESS, in the United Arab Emirates, linked to a large-scale solar development driven by Masdar and EWEC.
The project includes a 5.2 GW photovoltaic plant and a 19 GWh storage system, with the aim of delivering up to 1 GW of renewable energy continuously.
3. Green Energy Corridor – India: 12 GWh
India ranks third with the Green Energy Corridor, a strategic program linked to the integration of renewables and the strengthening of the electricity grid.
The project includes around 13 GW of renewable energy along with 12 GWh of battery storage, with a special focus on energy evacuation and the integration of resources in areas of high renewable potential.
India's presence in this ranking is no coincidence. The country faces one of the world's greatest energy challenges: sustaining the growth in electricity demand, reducing dependence on fossil fuels, and accelerating the deployment of renewables without compromising the stability of the system.
In this context, BESSs appear as a key tool to absorb variable generation, shift energy to critical times and improve grid reliability.
4. Atacama Oasis – Chile: 11 GWh
Chile positions itself among global leaders with Oasis de Atacama, Grenergy's megaproject in the north of the country.
Located in one of the areas with the highest solar radiation on the planet, the project combines 2 GW of solar generation with 11 GWh of storage. Its objective is to harness the photovoltaic resources of the Atacama Desert and transfer energy to nighttime or peak demand hours.
The Chilean case is especially relevant for Latin America. The high solar penetration in the north of the country has generated increasing challenges related to congestion, energy spills, and pressure on hourly prices. Faced with this scenario, BESS (Basic Energy Storage Systems) are no longer just a future alternative but have become essential infrastructure to sustain renewable energy growth.
Oasis de Atacama sets a trend because it shows that storage can be a concrete answer to one of the main problems of mature solar markets: how to capture value when generation is concentrated in the same hours of the day.
5. Darden Clean Energy – United States: 4.6 GWh
The United States appears with several projects within the top 10, and one of the main ones is Darden Clean Energy, in California.
The development includes a solar plant of up to 1,150 MW and a storage system of up to 4,600 MWh, equivalent to 4.6 GWh.
California is one of the world's most advanced markets for energy storage, driven by high renewable penetration, the need for flexible capacity, and system reliability requirements.
Darden Clean Energy reinforces a trend already established in the US market: large solar projects are beginning to be designed directly with batteries, not as a later addition, but as a structural part of the business model.
6. MTerra Solar – Philippines: 4.5 GWh
The Philippines enters the ranking with Mterra Solar, one of Asia's largest solar projects with storage.
The project includes 3.5 GWp of solar capacity and 4.5 GWh of BESS storage. Its deployment is planned in phases and aims to contribute large-scale renewable energy to Luzon's electricity grid.
The importance of MTerra Solar lies in its context. In island markets or those with more strained grids, storage plays a strategic role: reducing dependence on fossil fuels, improving security of supply, and facilitating the integration of large volumes of renewable energy.
The project also shows how Asia is beginning to accelerate the adoption of large-scale hybrid solutions, in which solar and batteries are presented as a competitive alternative to conventional generation.
7. Khavda BESS – India: 3.37 GWh
India reappears in the ranking with Khavda BESS, in Gujarat, within one of the world's largest renewable energy hubs.
The project reaches 3.37 GWh of storage and is part of the large Khavda renewable complex, driven by Adani Green Energy.
Its significance lies in the combination of scale, speed of deployment, and long-term strategy. Khavda is not just a battery storage facility, but a large-scale renewable energy platform where storage plays a central role in transforming variable generation into a more manageable supply.
For India, these types of projects are key to its goal of expanding renewables without compromising grid stability. For the global market, it confirms that energy storage is becoming inseparable from large solar and wind power hubs.
8. Edwards & Sanborn – United States: 3.3 GWh
Edwards & Sanborn, located in California, is one of the most iconic solar storage projects in the United States.
The complex combines approximately 875 MWdc of solar power with approximately 3.3 GWh of storage, and supplies utilities, corporate buyers, and public entities.
Its importance lies in the fact that it is a large-scale operational project, not just a development initiative. This allows for a clearer view of how BESSs participate in real markets, provide services to the system, and support renewable energy supply contracts.
Edwards & Sanborn also reflects an increasingly clear trend: clean energy buyers are looking not only for renewable MWh, but for more reliable, predictable delivery profiles that are aligned with their hourly needs.
9. Moss Landing – United States: more than 3 GWh
Moss Landing, also in California, is one of the historic names in large-scale storage.
The project reached approximately 3 GWh of capacity after successive expansions and established itself as a global benchmark for standalone battery systems.
Unlike other hybrid solar-storage projects, Moss Landing stands out for its role as a grid asset. Its primary function is to provide flexible capacity, absorbing energy when generation is surplus and delivering it during periods of high demand.
The case is especially representative of the Californian market, where batteries have gained prominence to cover afternoon ramps, improve reliability and reduce dependence on fossil fuel plants during critical times.
10. Crimson Energy Storage – United States: 1.4 GWh
The top 10 is completed by Crimson Energy Storage, in California, with 350 MW and 1,400 MWh of capacity.
The project, located in Riverside County, was developed as a standalone storage system and has been operational since 2022.
Their inclusion in the ranking reveals another dimension of the BESS market: not all large projects are associated with solar or wind generation on the same site. There are also independent assets designed to provide capacity, backup, and flexibility services to the grid.
Crimson Energy Storage is relevant because it demonstrates that storage can be an autonomous business when there are regulatory signals, long-term contracts, and markets capable of rewarding energy availability at critical times.
