Larsen & Toubro’s (L&T) Renewables business vertical has secured a major order to develop three Battery Energy Storage System (BESS) projects for a notable client in the Middle East. The company announced the order on August 25, 2026, stating that the three projects will collectively provide 6 GWh of energy storage capacity.
The order has been classified by L&T as a “Major” order. Under the company’s order classification system, a Major order falls in the value range of ₹5,000 crore to ₹10,000 crore. L&T has not disclosed the individual contract value of the three projects or identified the client in its announcement.
The scope of the order extends beyond the battery storage facilities. L&T will also undertake associated grid-interconnection infrastructure, including pooling substations and underground cables. The combination of storage facilities and grid infrastructure makes the order a broader project package covering both BESS deployment and the facilities required to connect the projects to the grid.
Three BESS Projects to Provide 6 GWh of Storage
According to L&T, the three projects will collectively contribute 6 GWh of storage capacity. Each project will feature a four-hour BESS system. The company stated that the systems will be capable of storing and dispatching energy to support grid stability and renewable energy integration.
L&T said the projects will enable energy shifting by allowing surplus clean energy generated during off-peak periods to be stored and subsequently delivered during peak demand hours. The company positioned the projects as an advancement in grid modernisation and renewable energy integration in the Middle East.
The announcement does not provide a project-wise breakdown of the 6 GWh capacity. It also does not disclose the individual locations of the three projects or their expected commissioning dates. Therefore, these details have not been included here.
Liquid-Cooled BESS Technology
The BESS solution planned for the projects will incorporate liquid cooling technology. L&T stated that the technology will provide higher power density, enhanced safety and extended operational life.
The use of liquid cooling is part of the technical specification highlighted by L&T for the projects. The company has not disclosed additional details about the battery chemistry, battery manufacturer, cell technology or individual system configuration in its August 25 announcement.
Grid Interconnection Included in Scope
Along with the storage facilities, L&T’s scope includes grid interconnections comprising pooling substations and underground cables. These components will form part of the infrastructure associated with connecting the BESS projects to the grid.
The inclusion of these facilities indicates that L&T’s responsibility under the order covers key electrical infrastructure associated with the storage projects, rather than being limited to the supply of battery systems. However, L&T has not provided a detailed project-by-project scope in its public announcement.
Focus on Performance, Safety and Execution
L&T highlighted the execution requirements associated with the three projects. According to the company, the projects involve stringent requirements related to plant performance, workforce mobilisation, safety, quality and timelines.
The company linked the order to its engineering and project-management capabilities, stating that the award reflects the trust and confidence placed by clients in L&T.
Middle East BESS Expansion
The order adds to L&T’s activities in the battery energy storage segment and expands its BESS project portfolio in the Middle East. The company described the three projects as significant for grid modernisation and renewable energy integration in the region.
The announcement is notable for the scale of the combined storage capacity. At 6 GWh, the three projects represent a substantial BESS deployment under a single order. L&T has, however, not disclosed whether the three projects will be executed simultaneously or provided a detailed execution schedule.
The company’s latest announcement also does not identify the specific Middle Eastern country or countries where the projects will be located. It only refers to the client as a “notable client in the Middle East.” Consequently, no specific country or client name can be confirmed from L&T’s official disclosure at this stage.
L&T’s Official Order Classification
L&T classifies orders according to their value, with “Major” covering contracts valued between ₹5,000 crore and ₹10,000 crore. The company’s August 25 announcement therefore places the Middle East BESS order within this range, but it does not state an exact contract value.
The order was also reported by L&T through its investor exchange-announcements platform under an announcement dated August 25, 2026. The company’s investor page lists the disclosure as an “Announcement under Regulation 30 (LODR)-Award_of_Order_Receipt_of_Order.”
The 6 GWh order represents a major BESS project win for L&T’s Renewables business and adds a large-scale storage component to the company’s Middle East project activities. With three four-hour BESS projects, associated pooling substations and underground cables, and liquid-cooled storage technology, the announced package covers both energy storage and related grid-interconnection infrastructure.
L&T has not disclosed the client’s name, individual project capacities, project locations, commissioning timelines, battery chemistry or exact contract value. These details therefore remain outside the confirmed information available in the company’s official announcement.
