A national high-tech enterprise and national “little giant” enterprise manufacturing transformers, medium- and low-voltage switchgear and energy storage systems for utility, industrial and commercial customers worldwide.
Founded in 2013, Ningbo Gongsheng Electric Technology Co., Ltd. is a national high-tech enterprise and national specialized, sophisticated, distinctive and innovative “little giant” enterprise with deep roots in the smart grid sector. We research and manufacture power equipment including transformers, high- and low-voltage switchgear, box-type substations and power distribution automation devices on fully automated intelligent production lines.
Building on years of technical accumulation in the power industry, we established Ningbo Gongsheng Energy Technology Co., Ltd. in 2022 and entered the new energy storage sector, focusing on energy storage system integration and the R&D, production and sales of core storage equipment. Customers receive practical, measurable and predictable energy investment solutions.
From transformer to switchgear to storage container, the portfolio is engineered around the same standards, so interfaces and delivery schedules line up across a project.

ERP, MES and WMS are connected into one industrial internet platform: equipment fully connected, data fully perceived, processes managed in real time. Every order stays visible from component machining to final delivery.
Standardised and parametric design backed by a large-scale knowledge system, delivering fast drawing output and automated design review.
Data-driven models watch the whole production flow, flag anomalies early and generate optimal responses from a smart factory brain.
ERP, MES and WMS are integrated end to end, so equipment, data and processes stay connected and every order stays on schedule.
Transformer, medium- and low-voltage switchgear and energy storage systems from a single qualified source, so interfaces and delivery schedules line up.
Products are designed and type-tested against GB/T standards, with performance verified in the factory before shipment.
Provincial R&D centre and postdoctoral workstation, with 70+ authorised patents including 11+ invention patents.
Pre-integrated and pre-commissioned assemblies cut site work and shorten project cycles.
Equipment already delivered to projects in Africa, South Asia, Central Asia, Europe and South America.
Response within one hour and on-site arrival within 24 hours for domestic project sites, with a 24-hour service line.
Recognition from national and provincial authorities across technology, manufacturing and intellectual property, backed by an in-house R&D platform and a postdoctoral workstation.
Grid-side storage, commercial and industrial storage, and power distribution projects delivered in Africa, South Asia, Central Asia, Europe and South America.
Grid-side storage adjacent to a 110 kV substation in Zhoushan, configured in 5 MW / 10 MWh units with 3× 10-second overload capability.
Grid-side storage next to the 35 kV Lujiazhui substation, commissioned in 2026 with multiple ancillary services.
Commercial and industrial storage projects from 0.1 MW / 0.215 MWh to 5.022 MW / 10.044 MWh across Zhejiang province.
