Top 10 BESS Projects: 10 GWh Samsung C&T Deal, 8.5 GWh Alsym Partnership (2024-2026)

The Battery Energy Storage System (BESS) market is undergoing a fundamental shift towards gigawatt-hour-scale projects, driven by the dual demands of grid modernization and powering energy-intensive data centers. Analysis of major announcements from 2024 to 2026 reveals that multi-GWh supply agreements and project pipelines are becoming the new standard. Key data points confirming this trend include a Texas developer securing over 10 GWh of capacity for data centers, Hithium and Samsung C&T partnering on a 10 GWh global pipeline, and ESS Inc. procuring 8.5 GWh of sodium-ion cells. The dominant theme emerging through 2025 and into 2026 is this immense scaling, where BESS moves from an ancillary grid service to a core infrastructure asset class essential for both public and private sector energy security.

BESS Applications, Adani Group’s 3, 530 MWh Project

The diversity of applications demonstrates the expanding role of BESS in the energy transition. Projects are moving beyond traditional grid services to become foundational infrastructure for new industries. The most striking example is the January 2026 announcement of a Texas developer securing over 10 GWh of capacity specifically to provide reliable power for data centers. This indicates a powerful new vertical market for energy storage. Concurrently, BESS remains critical for large-scale renewable integration, as shown by the Adani Group’s 3, 530 MWh project in India and California’s approval of the 4, 600 MWh Darden solar-plus-storage facility. Standard grid support remains a core function, with Boralex commissioning its 320 MWh Sanjgon project in Canada and RWE beginning construction on a 700 MWh system in Germany to bolster grid stability.

US Dominance, Hithium & Samsung C&T Global BESS Pipeline

Geographically, the United States continues to lead BESS deployment, with Texas and California as epicenters of GWh-scale activity. Texas stands out with multiple major announcements, including the 10 GWh data center supply, Sungrow’s 1 GWh deal with Spearmint Energy, and Recurrent Energy’s 200 MWh asset sale, driven by favorable market structures and massive industrial demand. California’s regulatory push for decarbonization is the force behind massive projects like the 4, 600 MWh Darden facility. However, global activity is rapidly accelerating, confirming that large-scale BESS is now a worldwide phenomenon. Major procurements by the Saudi Electricity Company (1, 000 MW) and the Adani Group’s entry in India signal that emerging energy powerhouses are making substantial investments. Global supply chain integration, exemplified by the 10 GWh global pipeline partnership between China’s Hithium and Korea’s Samsung C&T, further highlights the international nature of the market.

ESS Inc. 8.5 GWh Sodium-Ion Bet Beyond Lithium (2026)

While lithium-ion technology underpins most of the currently announced large-scale projects, recent deals signal a strategic diversification in battery chemistry. The most significant development is the May 2026 partnership between flow battery manufacturer ESS Inc. and Alsym Energy for an 8.5 GWh supply of sodium-ion battery cells. This is not a demonstration project but a massive commercial agreement, indicating that non-lithium chemistries are reaching a level of maturity and scale required for grid applications. The move highlights a concerted effort within the industry to mitigate supply chain risks associated with lithium and cobalt while exploring chemistries better suited for long-duration stationary storage. This suggests a future market where lithium-ion coexists with alternatives like sodium-ion and flow batteries, each optimized for different performance and cost requirements.

10 GWh Projects, BESS Developers Target Data Centers

Expect BESS developers to increasingly forge direct partnerships with large industrial and technology clients, bypassing traditional utility procurement pathways to secure offtake for GWh-scale projects. This shift from public tender to private contract will accelerate deployment and create new financing models.

• The primary signal is the January 2026 report of a developer securing 10 GWh of BESS capacity in Texas specifically for data center clients. This establishes a clear precedent for energy storage as a direct-to-consumer infrastructure asset for high-load industries.
• The May 2026 agreement between ESS Inc. and Alsym Energy for 8.5 GWh of sodium-ion cells demonstrates that the supply chain is maturing to support these massive deals with alternative, potentially lower-cost technologies, which is critical for the economics of direct power purchase agreements.
• The commissioning of the Sanjgon BESS in January 2026 shows that as markets mature, the focus shifts from simply winning bids to successfully executing and operating large, complex assets, a capability essential for servicing demanding private clients.
