ETENZ is advancing BESS enclosures for the Zhongwei grid-forming energy storage project, with 143 twenty-foot-class units and their structural, fire-service and electrical interfaces prepared in the factory.
ETENZ is advancing series production of 143 twenty-foot-class 5 MWh BESS enclosures for the Zhongwei project in Ningxia. The batch supports NR Electric energy storage equipment and uses one enclosure platform and project interface baseline for downstream installation and site deployment.
The 720 MW/1,440 MWh grid-forming LFP energy storage project in Shapotou District, Zhongwei, is designed around large-scale modular deployment. For the 143-unit package, ETENZ brings enclosure fabrication, internal supports and enclosure-side interfaces under a common process baseline so every batch can move efficiently into equipment installation.
Each enclosure combines the structural shell, internal battery-rack supports, an end fire-service zone and an auxiliary distribution area. Equipment mounting points, cable routes, earthing connections, service clearances and related openings are prefabricated to the system interface, allowing downstream assembly to follow the planned layout.
Critical dimensions, support positions, doors, service openings, fire-service zones and auxiliary electrical interfaces are fixed in common drawings and process criteria. Batch inspection controls variation and supports repeatable downstream assembly.
Completing the structure and interfaces before shipment reduces site modifications, stabilizes the equipment installation sequence, and creates a clear, repeatable foundation for staged transport, positioning and commissioning.

ETENZ is supplying the BESS enclosure scope for the China Three Gorges high-voltage direct-connected storage project in Haixi, Qinghai, contracted through NR Electric: 72 battery enclosures with their internal structural steelwork. The first unit has passed first-article review and the first batch shipped in late July 2026.

The first unit has passed first-article review and the first batch shipped in late July 2026.
In 2025, ETENZ delivered 200 air- and liquid-cooled compute containers under an OEM program, giving its customer a repeatable infrastructure platform that helped power rapid US expansion and growth into a leading crypto-mining contractor.
For the phase-2 project at the Julong Copper Mine on the Qinghai-Tibet Plateau, at an altitude of roughly 5,300 m, ETENZ completed the enclosure-shell manufacturing and interface provisioning of an ultra-long high-voltage variable-frequency-drive (VFD) E-House, giving TMEIC's HV VFD equipment a prefabricated enclosure platform that can be inspected, transported, and positioned ahead of time.
