Against the backdrop of intense competition in the global energy storage market and accelerated transformation of the energy structure in the United States, China's leading energy storage company, Tianhe Energy Storage, announced that it will further deepen its strategic cooperation with Lightshift Energy, a leading energy storage development and operation company in the United States. The two sides will expand their portfolio of energy storage projects in the United States, with a total joint delivery scale of over 1GWh for historical, ongoing, and upcoming projects, injecting strong momentum into the stable operation of multi state power grids and the replacement of clean energy in the United States. This upgraded cooperation is not only a continuation of mutual trust between the two sides, but also another proof of China's strength in the high-end North American market for energy storage technology and solutions.

The project portfolio for this expansion will fully adopt Tianhe Energy Storage Elementa Diamond series energy storage solutions, which have the core advantages of high energy density, excellent performance, and ultimate safety, and can accurately match the diversified needs of the North American market for grid regulation, peak shaving, valley filling, and flexible scheduling. Against the backdrop of sustained growth in electricity load across the United States and intensified pressure on the power grid due to frequent extreme weather events, these energy storage projects will become a key support for enhancing the resilience and reliability of regional power grids, providing stable and sustainable energy security for public utilities and local communities, while helping to reduce operating costs of the power system.

The deep binding between both parties stems from the accumulation of successful cooperation in the past. In 2024, Tianhe Energy Storage and Lightshift Energy have partnered to launch four energy storage projects in Groton, Holden, Paxton, and other locations in Massachusetts, USA. What is particularly commendable is that, during the emergency situation of high temperatures and heat waves in the northeast that year, Tianhe Energy Storage, with its efficient project management capabilities, completed the grid connection and commissioning of two power stations ahead of schedule, providing key capacity support for the local power grid during peak electricity consumption periods. Its practical performance verified the stability and reliability of the product delivery, laying a solid foundation for this scale expansion.

The continuous breakthrough of Tianhe Energy Storage in the North American market is inseparable from its localized layout and full chain service capabilities. Relying on a professional team and a well-established partner network in the North American region, Tianhe Energy Storage has achieved localized implementation of the entire process from system integration, EMS integration, grid testing to on-site debugging, ensuring that the project meets high standards in compliance certification, engineering execution, and long-term operation and maintenance in the North American market. Doug Alderton, the sales manager of Tianhe Energy Storage in North America, stated that the previous cooperation between the two parties fully demonstrated the synergistic advantages under high-pressure conditions. In the future, they will continue to provide more reliable and flexible energy storage solutions for the American community and promote the implementation of a common vision.

As a leader in the global energy storage field, Tianhe Energy Storage's business has covered six major markets worldwide, with a cumulative shipment volume of 12GWh as of the first half of 2025, ranking among the top international energy storage system integrators. The expansion of the 1GWh project portfolio not only demonstrates Lightshift Energy's high recognition of Tianhe's energy storage product performance and delivery capabilities, but also reflects the international market's widespread trust in China's energy storage technology, standards, and services. With the gradual implementation of the project, Tianhe Energy Storage will further consolidate its core competitiveness in the North American energy storage market, injecting strong momentum into its goal of doubling energy storage shipments by 2025.

In the complex environment of policy adjustments and demand growth in the current US energy storage market, the strategic cooperation upgrade between Tianhe Energy Storage and Lightshift Energy is of great industry significance. Faced with challenges such as subsidy reduction and increased compliance requirements in the supply chain, Tianhe Energy Storage has successfully crossed the market cycle with its technological strength and localized operational capabilities, providing valuable practical samples for Chinese energy storage enterprises to deeply cultivate the North American market. In the future, both sides will continue to use project cooperation as a link to support the energy transformation of the United States, promote technological innovation and sustainable development of the global energy storage industry, and write a new chapter in cross-border energy cooperation.Editor/Bian Wenjun
