In Zhejiang, where there is a significant peak-valley electricity price gap and growing demand for grid load balancing, C&I energy storage is rapidly becoming a key solution for enterprises to reduce costs and optimize energy usage.
In this project, TEP (Xi’an Tuwei Electric Co., Ltd.) collaborated with Zhongke Lide to provide Ningbo Shengxin Energy Co., Ltd. with a reliable and efficient power conversion solution. The deployed C&I energy storage system features a 261kWh Zhongke Lide storage cabinet, with its core power module being TEP’s self-developed 125kW TPCS PCS. The installation was carried out by Ningbo Yizhong PV Co., Ltd., leveraging their extensive experience and expertise to ensure smooth commissioning. TEP provided full technical support throughout, ensuring seamless integration and high performance of the PCS and storage cabinet. Since going live, the system has been running stably for over six months, with excellent feedback validating the high reliability and outstanding performance of the Zhongke Lide–TEP TPCS combination.
Client: Ningbo Shengxin Energy Co., Ltd.
Integrator: Ningbo Yizhong PV Co., Ltd. (YiZhou Energy Ningbo Regional Partner)
System Configuration: 2×261kWh Zhongke Lide C&I Storage Cabinets
Core Equipment: TEP 125kW TPCS Power Conversion System
Application Scenarios: Peak shaving & valley filling, demand response, load adjustment
01 | 20,000–30,000 kWh Discharge Monthly, ¥200K+ Saved Annually
The system operates on a two-charge, two-discharge mode, with monthly discharge ranging from 20,000 to 30,000 kWh. By effectively leveraging the peak-valley price differential, the system is projected to save the client over ¥200,000 annually, significantly enhancing economic efficiency and driving operational cost reductions.
02 | No Power Derating at 50°C, Stable in Extreme Heat
TEP’s 125kW TPCS PCS maintains full power output at temperatures up to 50°C, enabling uninterrupted operation even during Ningbo's hot summers and ensuring consistent system performance and reliability.
03 | Handles Complex Loads, Supports Diverse Applications
With fast response and precise control, the TPCS adapts quickly to fluctuating and high-power loads, adjusting output within milliseconds. This ensures stable power supply, maximizes energy utilization, and reduces power costs. Beyond peak shaving and demand response, the system also supports feeder optimization and other grid-interactive functions, helping clients enhance their energy strategies.
Zhongke Lide praised the performance of TEP’s 125kW TPCS PCS, particularly its stable operation under complex conditions and its adaptability to diverse application scenarios. They expressed confidence in deepening cooperation with TEP to explore broader storage applications, further optimize energy structures, and strengthen competitiveness. They believe that TEP’s advanced technology and services will continue to support their long-term sustainable growth.
TEP remains committed to delivering high-performance and reliable energy storage solutions. The successful deployment at Ningbo Shengxin Energy marks another milestone for TEP’s PCS in the C&I sector. We will continue to empower more enterprises with low-cost, high-yield storage systems through top-tier products and professional service. Together with our partners, TEP is driving toward a cleaner, greener energy future.
