Recently, overseas deployments in the energy storage sector have continued to accelerate. Chinese clean-tech leaders Envision Energy and Nenghui Technology have successively secured major European battery storage orders, advancing project buildouts in Germany and the Czech Republic, respectively. Meanwhile, TCL Solar achieved its first grid connection for a commercial and industrial (C&I) solar-plus-storage installation in Thailand, further expanding its application footprint across Southeast Asia.
Envision Energy Secures Another 442 MWh Battery Storage Order in Germany
Recently, Envision Energy and German clean energy developer ju:niz Energy announced a joint initiative to build the 442 MWh Smareg 13 (Vöhringen II) battery energy storage system (BESS) project in Bavaria, Germany. This represents the third storage project developed under their partnership, bringing their cumulative joint portfolio to nearly 600 MWh.
Smareg 13 is part of ju:niz Energy’s utility-scale storage asset portfolio in Germany, with ju:niz Energy overseeing project development, financing, and long-term operations upon completion. Located adjacent to the operational Smareg 12 facility, the project will further expand the scale of local energy storage infrastructure.
The facility will deploy Envision Energy's Gen 8 BESS platform, featuring a 4-hour storage duration alongside native grid-forming capabilities to provide essential grid regulation and stability support.
Nenghui Technology Signs 160 MWh Energy Storage Contract in the Czech Republic
Recently, Nenghui Technology signed an agreement for a utility-scale energy storage project cluster in the Czech Republic, totaling 38 MW / 160 MWh. Distributed across several regions in the country, the projects will primarily serve two key application scenarios: primary frequency regulation for the grid and electricity spot market trading.
The project cluster employs a system-level configuration of "DC battery containers + AC inverter-step-up transformer integrated units." The DC side will deploy 32 units of N20HC5000 liquid-cooled energy storage containers—each with an individual capacity of 5.015 MWh—yielding a total DC-side capacity of 160.48 MWh (noted as MW in original Chinese sources). The AC side includes 6 integrated inverter-transformer cabins across three capacity tiers (two 4 MW units, two 5 MW units, and two 10 MW units), totaling 38 MW, tailored precisely to meet the grid connection capacities of regional substations.
With this contract secured, Nenghui Technology's cumulative energy storage footprint in the Czech market has reached 50.5 MW / 205 MWh.
TCL Solar Connects 100 kWh Storage Project to the Grid in Thailand
Recently, the TCL BlueArk X5 completed its initial installation and successful grid connection in Thailand. The project pairs a 50 kW / 100 kWh commercial and industrial (C&I) energy storage system with an 80 kWp TCL solar array, leveraging solar-plus-storage synergy to power local corporate operations with clean energy.
This project marks the market debut of the TCL BlueArk X5 in Thailand. The system supports multi-source energy integration—including solar PV, the utility grid, battery storage, and diesel generators—and supports parallel multi-unit configurations, allowing flexible operational setups tailored to varying corporate load profiles.
Following the rollout of the BlueArk X5 in Thailand, TCL Solar will conduct recurring product and technical training sessions for regional channel partners, installers, and engineering technicians, facilitating continuous collaboration to address practical project implementation requirements.
