1. CALB’s ¥10 Billion Battery Base in Shandong Receives EIA Approval, Targeting 100 GWh Capacity
On June 10, CALB’s three major battery projects in Zaozhuang, Shandong, received environmental impact assessment approval. With a total investment of ¥9.9 billion, the projects cover the full value chain of commercial vehicle batteries, energy storage batteries, and battery PACK integration systems. The commercial vehicle battery and energy storage battery segments are each planned for 50 GWh of annual capacity, while the supporting PACK integration system is expected to reach 60 GWh per year.
Once completed, the base will form a 100 GWh-level battery production cluster, helping fill the capacity gap in northern China’s energy storage cell and system supply, and further strengthening the scale advantage of China’s domestic energy storage battery supply chain.
2. Tecloman Energy Storage Signs MoU with Induk KUD to Expand Southeast Asia’s Solar-Plus-Storage Market
On June 16, Tecloman Energy Storage signed a memorandum of understanding with Induk KUD, the National Federation of Rural Co-operatives, in Jakarta. Leveraging the federation’s extensive grassroots network across Indonesia, the two parties will jointly develop integrated photovoltaic-plus-storage energy projects Induk KUD covers 31 provinces in Indonesia and serves
more than 10 million member households, giving the parnership strong local market access. During the signing ceremony, the two sides also inaugurated a Tecloman product showroom. Future cooperation will cover local production support for energy storage equipment and technical talent training, accelerating the deployment of Chinese energy storage solutions in Indonesia’s rural and community markets.
3. Revised Distributed Power Grid-Connection Guidelines Take Effect, Easing Storage Interconnection Restrictions
On June 18, the revised Guidelines for Carrying Capacity Assessment of Distributed Power Access to Power Systems officially took effect. The new guidelines remove the rigid 80% cap on transformer reverse loading and replace it with a dynamic carrying capacity assessment mechanism. This change significantiy eases grid-connection hresholds for residential and commercial & industrial energy storage systems, addressing previous bottlenecks in distributed storage interconnection and capacity expansion. The policy is expected to open up new opportunities in distrbuted scenarios such as solar-storage-charging integration and virtual power plants, and providing policy support for the scaled and high-density grid connection of small and medium-sized storage systems and revitalizing China’s distributed energy storage market.
4. HyperStrong’s 7 MWh-Class High-Capacity Storage System Certified under Beijing’s First Major Technical Equipment Program
HyperStrong’s self-developed 7 MWh-class high-capacity intelligent energy storage system has been certifed under Beijing’s “First Major Technical Equipment (Set)” program. The product has been delivered in batches with capacities of up 7.8 MWh. It uess 587 Ah LFP cells and adopts an integrated 20-foot container design. Rather than simply chasing larger capacity, the system strikes a balance optimization across safety standards, station-level compatibility, system integration and electrochemical perfoemance. It sets a benchmark for high-capacity energy storage integration in China and supports the localization and commercial-scale deployment of utility-scale energy storage equipment.
5. Long-Duration Solar-Plus-Storage Project Commissioned in Chile as Latin America’s Storage Market Gains Momentum
ContourGlobal recently brought online the Victor Jara project in Chile, comprising 231 MW of PV capacity and a 200 MW/1.3 GWh energy storage system with 6.5-hour discharge duration. The project is a benchmark long-duration storage project in Latin America and is backed by a 15-year power purchase agreement for solar power offtake. It forms part of thelarger Atacama solar-pius-storage cluster,which is planned to include 4 GW PV capacity and 11 GWh of energy storage, with stirage equipment supplied by CATL and BYD. Around 1.5 GWh of storage capacity has recently been continuing to increase their exposure to large-scale local projects, signaling that Latin America’s energy storage market is entering a period of rapid expansive.
6. JinkoSolar Subsidiary Secures ¥2 Billion Capital Injection from Three Bank-Backed Strategic Investors
JinkoSolar announced that Haining Jinko, its key majority-owned subsidiary, has completed a ¥2 billion capital increase with three from three strategic investors: Xingyin Investment, Zhongyou Investment and Zhaoyin Investment. Upon completion, the three investors will collectiveiy hold a 17.926% stake in Haining Jinko, which was valued at ¥9.157 billion before the transaction.
The proceeds will be used to repay financial and iperating liabilities. JinkoSolar will retain a combined direct and indirect stake of 75.0045%, maintaining controlof the subsidiary. The capital increase is expected to strengthen Haining Jinko's capital structure and reduce its leverage ratio. The participation of bank_backed investors also reflects institutional confidence in the long-term outlook for the PV and energy storage sector.
7. Longi, Envision, and GCL Establish New Energy Storage Subsidiaries, Accelerating Integrated Solar-Storage Deployment
Three major renewable energy companies have recently established wholly owned energy storage subsidiaries, reflecting an accelerated push into regional storage deployment. LONGi set up a new energy storage company in Shenzhou, Hebei, on June 4, with a registered capital of ¥1 million and a business scope covering solar PV, energy storage, and charging station operations. On June 11, Envision established a new energy storage company in Jiangyin, Jiangsu, also with a registered capital of ¥1 million and a focus on wind-plus-storage applications. On June 10, GCL registered a new energy storage company in Shaoxing, Zhejiang, with a registered capital of more than ¥554 million and a business scope covering energy storage R&D and energy project development.
The moves show that major renewable energy players are building localized platforms to support project execution across a wider range of energy storage applications.
