The Tangshan Huaxi Special Steel 15MW/30.09MWh energy storage station has been connected to the grid, and in its first 15 days of operation it generated over 300,000 yuan in profit — showing the commercial potential of energy storage in high-energy-consuming industries such as steel.
The Tangshan Huaxi Special Steel 15MW/30.09MWh energy storage station was invested in, built, and is operated by Jingye New Energy on a one-stop basis. The project started on 15 February 2025 and completed planning, construction, installation, and grid-connection commissioning in about two months, entering trial operation in mid-April 2025. Following Northern Hebei's time-of-use pricing, it runs two charge–discharge cycles per day, shifting about 50,000 kWh daily through peak shaving and valley filling.
With a total investment of about 32.5 million yuan, the project's economics can be viewed two ways:
In its first 15 days connected to the grid, the station generated over 300,000 yuan in profit.
The station uses Jingye New Energy's independently developed 5MWh liquid-cooled energy storage module, compatible with mainstream battery cells and using high-efficiency composite cooling for up to 90% system efficiency. Safety is protected by multi-level self-fusing and real-time monitoring, achieving millisecond-level response to thermal runaway.
Jingye New Energy focuses on energy storage system integration and CCS busbars. Its project capabilities are backed by the Level 2 General Contracting Qualification for Electric Power Engineering, an Engineering Design Qualification, a Construction Enterprise Qualification, and a Permit for Installation (Repair, Testing) of Power Facilities.
How much does the Huaxi energy storage station earn?
About 8 million yuan/year if a steel plant self-invests (3.9-year payback, ~26% IRR), or about 6.95 million yuan/year for Jingye New Energy under its build-own-operate model with an 85% revenue share (4.6-year payback).
How big is the station and how was it built?
15MW/30.09MWh, using 6 × 5.015MWh liquid-cooled containers with 6 × 2.5MW integrated PCS. Jingye completed it in about two months, from a 15 February 2025 start to mid-April 2025 trial operation.
How does energy storage cut a steel plant's costs?
By charging during cheap off-peak/valley hours and discharging during expensive peak hours (peak shaving and valley filling), the plant lowers its electricity bill without disrupting production.

Why EV Charger Efficiency Matters for Commercial Charging Operations
A commercial charging site can lose thousands of dollars each year through inefficiency long before an operator notices a hardware failure. When a DC fast EV charger converts grid electricity into battery power, energy is lost as heat, switching loss, cable loss, cooling demand, and standby consumption. A charger operating at 94% efficiency instead of 97% may appear to differ by only three

EV Charging Infrastructure for Electric Bus Fleets
EV Charging Infrastructure for Electric Bus Fleets must deliver reliable power, safe operation, and predictable charging costs every day. An electric bus depot needs enough charging capacity to serve vehicles without delaying routes. Depot charging, battery management systems, and fleet scheduling are now central parts of daily bus operations. Electric bus fleets also require accurate energy

BESS Commissioning: Key Tests Before Commercial Operation
BESS commissioning confirms that a battery energy storage system is safe, reliable, and ready for commercial operation. A complete battery commissioning test checks the battery management system, power conversion system, and site controls before the asset serves the grid. Poor testing can cause failed grid connection tests, low round trip efficiency, unexpected shutdowns, or unsafe operating
