Cases

The Evolving Energy Landscape Commercial & Industrial (C&I) Energy Storage Systems (ESS) are pivotal for integrating clean energy, reducing transmission losses, and accelerating the transition towards dual-carbon goals. Favorable electricity pricing policies, widespread demand response programs, and falling lithium battery costs are increasingly validating C&I ESS applications, establishing them as key market players.   Limitations of Traditional C&I ESS Approaches Traditional time-based strategies for charging and discharging C&I ESS were adequate for simple, stable industrial park loads. However, modern parks feature dynamic elements like solar PV, distributed wind power, EV charging, and adjustable loads. These complexities, coupled with the need for greater economic efficiency (e.g., managing demand charges), mean simple timed strategies are no longer sufficient.   FGI’ s Advanced C&I Energy Storage Solution Industrial parks typically have high power consumption and prolonged peak loads. Integrating renewables necessitates robust energy storage for supply-demand balancing. Our "Industrial Park + ESS" model enables the storage of surplus renewable energy (e.g., from solar PV) for use during peak hours. This stabilizes the park's power supply, alleviates grid pressure, provides backup power, and allows for significant cost savings through peak-valley arbitrage, especially given the common industrial tariff structures.   Application Showcase: Optimizing a Manufacturing Facility Client Profile: An auto parts manufacturer in Wenzhou, Zhejiang, with existing 2MW solar PV, 80kW EV charging stations, and flexible production lines, leading to increasingly unpredictable and uncontrollable electrical loads. Our Solution: Following a detailed site analysis, we implemented a dynamic, real-time load tracking solution using six 100kW/215kWh C&I ESS units integrated into their low-voltage distribution system. ​ Mechanism & Benefits: The ESS acts as an energy reservoir, intelligently coordinating with the client’s solar PV, EV chargers, flexible production lines, and general operational loads. Through high-speed data integration and real-time analytics, the system dynamically adjusts ESS charge/discharge states and power. This progressively optimizes the client's energy economics, significantly reducing electricity costs and enhancing overall profitability.   Key Features & Benefits of Our Solution Dynamic Load Optimization & Cost Savings: Intelligent algorithms continuously optimize "buy low, sell high" strategies by tracking load changes in real-time. Significantly reduces electricity costs through peak shaving and optimized demand charge management. Achieves a true "on-demand, source-follows-load" capability, adapting instantly to changing needs. Enhanced Flexibility & System Integration: Facilitates flexible integration and adjustment of renewable energy sources (solar, wind) based on production demands. Breaks down operational silos by seamlessly connecting ESS with PV systems, EV chargers, and various production loads through advanced information networking. Proactive Strategy & Expanded Value: Transforms ESS from a passive peak-shaving tool into an active system that constantly seeks and implements optimal energy strategies. Provides a versatile solution that accommodates both existing and evolving load profiles in industrial parks.                                 Production Base: North of the middle section of Jincheng Road, Economic Development Zone, Wenshang County R&D Center: No. 21, Gongye North Road, Baoshan Sub-district, Licheng District, Jinan City Email: overseas@fengguang.com   Website: www.fengguang.com.                                  

As China pursues its "dual-carbon" goals, new energy development is surging in high-altitude regions like Tibet, Sichuan, and Yunnan. Tibet alone exemplifies this vast potential, with annual solar radiation equivalent to 240 billion tons of standard coal, and a technically exploitable photovoltaic capacity of 12 billion kilowatts across 340,000 square kilometers below 5,000 meters. However, these elevations present severe challenges: lower air density impairs equipment cooling and necessitates modified designs for crucial systems such as Static Var Generators (SVG), which are vital for stable grid integration and harnessing this potential.   Successfully developing these rich, high-altitude renewable resources is key to optimizing China's energy structure, achieving greater energy self-sufficiency, and fostering green development. FGI directly addresses the demanding operational environment with specialized solutions. Our advanced Static Var Generators (SVG) are specifically engineered with optimized thermal management and enhanced insulation characteristics to perform reliably in thin air, ensuring efficient and stable power conversion. These tailored SVG systems are instrumental in enabling the full utilization of new energy in these vital yet challenging regions.     A photovoltaic project in Lijiang, Yunnan – Altitude 4000m       A photovoltaic project in Tibet – Altitude 4100m       A photovoltaic project in Lixian County, Sichuan Province – Altitude 4000m     Solution Advantages FGI actively responds to policy directives and user requirements.
