According to EnergyTrend, the energy storage sector saw a surge in order wins this week. Enterprises including CORNEX, LONGi, BYD Energy Storage and SAV New Energy secured new orders and cooperation deals, covering energystorage orders and projects totalling over 58 GWh.
CORNEX Signs 50 GWh of New EnergyStorage Orders
On May 13, at the 18th China International Battery Fair (CIBF 2026), CORNEX signed cooperation agreements with five energystorage enterprises: CRRC Zhuzhou Institute, Clou Electronics, Wolong Energy Storage, Cubenergy and Growatt. The contracted products include 648 Ah, 588 Ah and 314 Ah batteries as well as 100 Ah residential energystoragespecific batteries, with total order volume reaching 50 GWh.
The five partners cover niche segments including energystorage system integration, residential energystorage equipment, prefabricated cabins and power equipment. Key cooperation details are as follows:
LONGi’s First Industrial & Commercial EnergyStorage Project in Germany Connected to Grid
On May 13, LONGi announced that its first industrial and commercial energystorage project in Germany was officially gridconnected recently. Located in northeastern Germany, the project integrates LONGi’s OmniCube A215 battery energystorage system into a photovoltaic power station operated by local asset owner Stadtwerke Stralsund. Installation and commissioning were completed by late April.
The project adopts LONGi selfdeveloped OmniCube A215 PVstorage integrated flexible energystorage system. Its highly integrated design caters to multiple scenarios such as commercial complexes, industrial parks, PVstorage charging stations and offgrid areas. Successful grid connection marks LONGi’s transformation from a module manufacturer to a comprehensive energysolution provider.
Notably, the German market is known for strict regulatory oversight and technical requirements. The rapid project rollout strongly validates LONGi’s overall strengths in regulatory compliance and adaptability to complex power grids.
Since 2026, LONGi has accelerated its layout in the European energystorage market. On April 1, it launched the fullstack LONGi ONE PVstorage integration strategy globally. On April 21, its PVstorage Technology Service Center in Madrid, Spain officially went into operation. Recently, its first energystorage projects in Italy and Finland were also successfully gridconnected and commissioned.
BYD Energy Storage Signs Strategic Cooperation Agreement
On May 13, BYD Energy Storage held a strategic cooperation signing ceremony with Corvus Energy AS. The two parties will establish an allround and indepth strategic partnership in the marine newenergy sector to advance R&D, certification and largescale deployment of highrate lithium iron phosphate marine battery systems.
As a global benchmark for zeroemission solutions in marine and port sectors, Corvus Energy AS provides energystorage and fuelcell system portfolios compatible with all vessel types. In marine new energy, leveraging core technological advantages in highsafety and highrate lithium iron phosphate batteries, BYD Energy Storage has widely applied innovative solutions in electric ships, industrial equipment and construction machinery, building a complete product matrix covering diverse vessel demands.
SAV Signs 135 MWh EnergyStorage Project in Bosnia and Herzegovina
On May 13, SAV DIGITAL POWER announced a newly secured 135 MWh largescale energystorage project in Bosnia and Herzegovina. This deal represents a breakthrough in the largescale application of SAV’s energystorage containers in the Balkan Peninsula of Europe.
The project deploys 27 units of Saiwei selfdeveloped X7series 5 MWh energystorage containers featuring stable capacity and high integration. Compatible with local grid standards and complex operating conditions, they ensure stable regional power supply while reducing grid upgrading costs.
In addition, on May 12, Saiwei announced the successful delivery of its 200 MWh utilityscale energystorage project in Austria. At present, Saiwei has reached international advanced levels in product compliance, technical standards and safety performance, capable of crossborder project delivery, grid connection and auxiliary service market operation.
8.5 GWh Overseas SodiumIon Battery Order
According to foreign media reports in late April, U.S. iron flow battery manufacturer ESS Tech Inc (ESS) signed a letter of intent with Massachusettsbased sodiumion battery firm Alsym Energy. ESS will incorporate 8.5 GWh of Alsym’s sodiumion batteries and modules into its product portfolio.
Both ESS and Alsym noted that the cooperation marks ESS’s official entry into short and mediumduration battery energystorage system (BESS) segments. Under the plan, Alsym and ESS will kick off delivery of battery cells and packs in Q3 2026.
Headquartered in Oregon, ESS previously focused on iron flow battery technology mainly for longduration energystorage applications of 824 hours. The partnership expands its product line into medium and shortduration energy storage.
