On 26 December, Hebei Jiantou AVIC Saihan Green Energy Technology Development Co., Ltd. (Saihan Green Energy) achieved a major milestone with the successful completion of a 72-hour trial operation for its Xingtai Yanzhao 10MW/40MWh Vanadium Flow Battery Energy Storage Station. The project passed comprehensive charging and discharging tests, signalling its readiness for commercial operation.
This landmark facility is part of Hebei's first hybrid vanadium-lithium energy storage project, initiated on 15 March following approval from the Hebei Development and Reform Commission. Covering approximately 100 acres, the project will be developed in phases, with the initial phase involving a 110MW/240MWh energy storage station. In April, a 200MW/800MWh project received record approval, followed by crucial regulatory milestones, including power line construction approval in September and grid connection feedback in October.
Saihan Green Energy began planning the 10MW/40MWh Vanadium Flow Battery Energy Storage Station in April under the guidance of Hebei Construction & Investment Group. Rapid advancements included product upgrades, construction, and equipment installation, leading to significant achievements:
- 15 November: Successful commissioning of a 220kV step-up station.
- 17 November: High-voltage power delivery to the Vanadium Flow PCS unit.
- 25 November: Activation of the first battery unit.
- 15 December: Completion of comprehensive charging and discharging tests.
This project sets a new industry benchmark for efficiency and speed, overcoming challenges such as tight schedules, complex coordination, and stringent environmental controls. Over 130 days of effort culminated in record-breaking progress for the vanadium flow battery sector.
The Hebei Xingtai Yanzhao Energy Storage Project exemplifies Hebei Construction & Investment Group's commitment to advancing green energy and creating a flexible, reliable power system. This facility will enhance grid flexibility and efficiency in western Xingtai, increasing photovoltaic utilization, reducing annual coal consumption by 43,000 tons, and cutting CO2 emissions by 114,000 tons. These efforts align with the group’s strategic vision for low-carbon energy transformation and sustainable development.
