I. Market Orders and Contracts: Large-scale Orders in the GWh Range Are Increasing
This week, the signing of international energy storage market orders remained extremely active. During the SNEC 2026 exhibition, the total amount of energy storage order signings exceeded 92.7GWh.
II. Policy and Regulatory Updates: Multiple Countries Intensify Release of Favorable Measures
Europe
On June 9th, the European Commission made a decision to officially establish the “Battery Booster Mechanism” (Decision (UE) 2026/1283), as a financing decision for 2026, with the aim of supporting investment in the European battery industry.
The German Federal Grid Agency has officially implemented a new policy for energy storage grids: For large-scale electrochemical energy storage projects connected to the grid before August 4, 2029, the usage fees for both charging and discharging cycles will be waived. Due to the uncertainty of the policy, no new investment projects in the German energy storage market have been implemented in the past five months. However, after the policy is implemented, it is expected to activate billions of euros of private capital.
In accordance with the requirements of the European Union, by June 2026, each national regulatory authority is required to approve and issue a report on the assessment of flexibility needs for the next 5 to 10 years.
The French TagEnergy company has launched a 240MW/480MWh energy storage project (the largest one in the country at present), while the Spanish Iberdrola company has launched a 58MW/120MWh energy storage project. The Belgian Engie company has collaborated with NHOA Energy to launch a 320MWh energy storage project.
North America
IESNA Midwest 2026 (Midwest Energy Storage Exhibition in the United States) was held in Rosemont, Illinois from June 15th to 17th, focusing on topics such as grid transformation, AI-driven power demand, and financing of clean energy.
China
On January 30, 2026, the National Development and Reform Commission and the National Energy Administration jointly issued the “Notice on Improving the Capacity-based Electricity Price Mechanism for Power Generation Sides”. Grid-side independent new energy storage facilities that meet the conditions can receive “basic salary” income based on their capacity. In Gansu Province, the rate is 330 yuan per kW per year, while in Hubei Province, it is 165 yuan per kW per year, but with an additional 98% availability rate assessment.
III. Technological Progress and Product Innovation: Announced at SNEC Exhibition
The 19th SNEC International Solar Photovoltaic and Smart Energy Conference, held from June 3rd to 5th, became a showcase for global energy storage technological innovations. The number of energy storage-themed exhibition halls exceeded that of photovoltaic exhibition halls for the first time:
Haiden Energy Storage launched the world’s first native 8-hour long-term energy storage solution – the ∞Power 6.9MWh system. It adopts the world’s first 1300Ah long-term energy storage-specific battery cell, and the system has a design lifespan of up to 25 years. At the same time, it made its first public appearance of the ∞Cell 650Ah large-capacity battery and the ∞Power 10+MWh product solution.
Sodium-ion batteries become the focus of the exhibition: Ruipulianjun has released a 320Ah sodium-ion battery cell with a cycle life exceeding 20,000 times, capable of operating in extreme temperatures ranging from -50°C to 60°C; Kunyu Power Supply and Hanxing Energy also showcased sodium-ion energy storage products.
IV. Major Project Progress: Milestones Completed and Put into Operation in Multiple Countries
Europe
The largest battery energy storage project in Hungary has officially gone into operation. It was invested by Greenvolt Power and equipped with a 288.6 MWh Cube battery energy storage system provided by BYD. This system can meet various application needs such as grid frequency regulation and peak load reduction, and will help facilitate the large-scale grid connection of renewable energy in the Central and Eastern European regions.
The Pazardzhik Energy Storage Project in Bulgaria was successfully connected to the grid. The total installed capacity is 10MW/31MWh. Equipped with the EMS energy storage management system, it achieves triple benefits including peak-valley arbitrage and auxiliary services.
Middle East/Africa
The world’s largest grid-connected modular energy storage cluster – the third phase of Saudi Arabia’s SEC 2.5GW energy storage project – has successfully been connected to the grid. It consists of over 2,000 PCS and features grid connection functions such as power regulation, primary frequency regulation, dynamic voltage regulation, black start, and adaptive control between the strong and weak power grids. It covers five key power regions including Riyadh and Rabigh.
The largest photovoltaic-storage power station under construction in Africa – the Abydos II photovoltaic-storage project in Egypt – successfully completed the first reverse power transmission at its 500KV substation. This project consists of a 1GW photovoltaic power station and a 600MWh energy storage system.
Australia
The Orana battery energy storage project in New South Wales (415MW/1660MWh) has been completed on time and has reached full power output. It is about to enter the commercial operation stage. This project is the largest one completed by Akaysha Energy to date. Its parent company, BlackRock, is currently opening up data spaces for potential sale.
The 60MW/163MWh battery energy storage project at Clement Gap has been fully operational. Adjacent to the 56.7MW wind power project that is already connected to the grid, it forms a “wind-solar-storage” collaborative operation cluster of clean energy. This is the first project to be completed and put into operation among the first batch of winning projects under the Federal Government’s “Capacity Investment Program” (CIS).”
Frontier Energy has completed a 110 million Australian dollar financing round, facilitating the construction of the first phase of the Waroona solar-storage project (132MW photovoltaic + 81.5MW/565MWh energy storage).
V. Investment and Financing Trends: Capital Accelerates Inflow
U.S. energy storage developer esVolta completed a $450 million expansion of its corporate credit line, supported by its 30 energy storage projects totaling 25GWh, of which 2GWh are already operational or under construction.
The European Bank for Reconstruction and Development is considering providing 30 million euros in financing for the BESS-2 project (246MW/512.5MWh) of the Tenevo Solar joint venture in Bulgaria.
Kirkland & Ellis assisted Real Assets Investment Management and White Summit Capital in investing in ENKA Energy Transition, deploying approximately 300 million euros to build and operate the largest 500MW BESS platform in Europe.
VI. Key Trends and Summary
Overall, the international energy storage market in mid-June 2026 exhibited the following notable trends:
The industry is still in a high-growth cycle: During the SNEC exhibition alone, the signed energy storage orders exceeded 92.7 GWh. The overseas expansion pace of Chinese energy storage enterprises has accelerated comprehensively. Leading companies such as Jinko, CATL, Haibosichuang, and Yiliu Lithium Energy have witnessed a strong growth momentum in their overseas orders.
Multiple favorable policies: Germany has waived the cost of energy storage grid facilities until 2029. The EU has established a “battery-driven mechanism” to increase investment. China has introduced a capacity-based electricity price mechanism for the power generation side. Major economies around the world are all using policy measures to encourage investment in energy storage.
Diversification of technical routes: Sodium-ion batteries are accelerating their transition from the laboratory to industrialization. General Motors and Peak Energy have reached a strategic partnership to develop sodium-ion battery energy storage systems. Long-duration energy storage products have also begun to be implemented on a large scale. Haiden Energy launched its first 8-hour native energy storage solution, marking the industry’s evolution towards longer-duration energy storage applications.
Regional coordinated development: From the super-large grid-connected energy storage project of Saudi SEC to the utilization of the largest energy storage facilities in France/Spain, and finally to the commissioning of the first energy storage project under the CIS framework in Australia, the global energy storage infrastructure is shifting from “point-based construction” to “system-wide layout”.
