ETENZ is manufacturing 143 twenty-foot 5 MWh BESS enclosures for a grid-forming storage project in Zhongwei, with internal supports plus fire and electrical interfaces prepared to the system package.
ETENZ is organizing series production of 143 twenty-foot-class, 5 MWh BESS enclosures for a large grid-forming energy storage project in Zhongwei, Ningxia. The batch supports an NR Electric system package and provides a consistent enclosure platform for equipment installation, commissioning and site deployment.
The public tender identifies a 720 MW/1,440 MWh grid-forming LFP storage plant in Shapotou District, Zhongwei. That figure describes the overall project, not ETENZ’s supply. ETENZ’s role is the manufacturing batch of 143 enclosures for 5 MWh units.
The work covers enclosure fabrication, internal battery-rack supports, the end fire-system service compartment and auxiliary distribution area, plus openings, equipment mounting positions, cable routes and maintenance clearances. Battery modules, PCS equipment, BESS integration and plant EPC are outside ETENZ’s scope.
Large batches require more than a compliant first unit: dimensions and interfaces must stay repeatable across every production lot. Support positions, doors, service access, fire-system areas, auxiliary connections and critical openings are therefore controlled against one project baseline and checked by batch.
Preparing enclosure-side interfaces before shipment reduces site drilling and improvised rework, supports a steadier equipment-installation sequence, and clarifies the handover boundary for staged transport, placement 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.
