Creating a better future via innovation-driven and talent-led strategy
Jiawei focuses on shared energy storage, industrial and commercial energy storage, “Power Generation-Transmission-Loading-Storage” and virtual power plant business. By continuously deepening product services and actively exploring more application scenarios, the Company aims to accelerate its digital transformation, build a more integrated full industry chain, and thus provide customers with comprehensive energy system solutions
New energy consumption can alleviate wind and solar power losses, improve economic efficiency, track planned output to improve power generation stability, smooth output fluctuations, and improve grid connected power quality.
Joint frequency-phase regulation can effectively improve the frequency stability of the power grid and increase the revenue of power plants.
Peak shaving and valley filling can alleviate electricity consumption conflicts during peak periods and improve the utilization rate of transmission and distribution lines.
Peak shaving frequency regulation can achieve millisecond level response, reduce the impact of load fluctuations on the power grid, and improve power grid stability.
Peak valley arbitrage, backup power supply, demand response, and dynamic expansion

Location: Jiancheng Town, Yunnan County, Yunfu City, Guangdong Province
Scale: Energy storage configuration capacity 15MW/15MWh
Features: The “agricultural-photovoltaic complementary” model not only improves land use efficiency and conforms to the national trend of green and environmentally friendly agriculture, but also solves employment and increases farmers’ income. The implementation of technology efficient circular ecological agriculture has created good economic, social, and ecological benefits.
Location: Guangzhou City, Guangdong Province
Scale: 20 * SES-100K (100kW/200kWh)
Features: There is one energy storage system installed next to the low-voltage distribution room, totaling 4MWh, used for peak shaving and valley filling, which can bring considerable electricity price benefits to users. Installing guardrails outside at the same time takes up a very small and aesthetically pleasing area.
