Amid China's rapid economic development and industrial restructuring, businesses increasingly demand reliable energy while seeking enhanced efficiency and cost control. In particular, the proliferation of solar installations and the prevalence of intermittent surplus electricity generation during industrial processes have posed challenges for effectively integrating renewable energy, managing power quality, and utilizing irregular, stochastic energy surpluses. This article explores how GREEN POWER's energy storage solutions address these issues for a Shanghai industrial park, a Zhejiang technology firm, and a Guangdong nanomaterials manufacturer, facilitating efficient energy use and cost optimization.
**Case One: Solar Integration Dilemma at a Shanghai Industrial Park**
An industrial park in Shanghai has extensively installed photovoltaic (PV) panels on its building rooftops, generating substantial clean energy. However, the unpredictable nature and intermittency of PV output lead to significant surplus energy that cannot be fully utilized, compromising power quality. GREEN POWER addresses this challenge with a 500KW/1MWh containerized energy storage system, seamlessly integrating distributed renewables, intelligent storage systems, and an integrated energy management system, offering both grid-connected and standalone operation capabilities.
This storage solution primarily enables high levels of renewable energy absorption by dynamically matching PV output with the park's load demands, minimizing energy waste. It also significantly enhances power quality through advanced filtering technologies and dynamic voltage-frequency regulation, mitigating fluctuations from PV generation and ensuring grid stability. Lastly, the system implements peak-shaving and valley-filling strategies, charging during off-peak hours and discharging stored energy during daytime peaks, thereby reducing overall electricity costs and enabling the park to tangibly save on energy expenses while embracing green energy practices.
**Case Two: Managing Intermittent Surplus Electricity at a Zhejiang Technology Firm**
During product testing phases, a Zhejiang-based technology company encounters substantial amounts of surplus electricity with intermittent and stochastic characteristics, which are difficult to allocate to other on-site loads. To tackle this issue, GREEN POWER tailored a 500kW/1MWh zero-carbon factory energy storage solution specifically for the firm.
The solution ingeniously incorporates valley and hydrogen operating modes. Under the valley mode, the storage system absorbs surplus energy during low-demand, off-peak hours and releases it during daytime peaks, substituting expensive grid power and significantly lowering electricity costs. In the hydrogen mode, excess electricity is utilized for water electrolysis to produce hydrogen for storage and later use during periods of energy scarcity or seasonal shortages, further enhancing energy utilization. These versatile operational modes not only resolve the issue of utilizing intermittent energy but also effectively implement peak-shaving, resulting in substantial savings on the overall electricity costs for the facility.
**Case Three: Mitigating Summer Power Curtailment Risks for a Guangdong Nanomaterials Factory**
A Guangdong-based nanomaterials manufacturer, operating in a precision manufacturing sector with stringent power supply stability requirements, faces production disruptions during summer peak demand periods when power curtailments may occur. To mitigate this risk, GREEN POWER deployed a 2MW/5.4MWh commercial and industrial-scale energy storage system to safeguard the company's steady production.
This storage system serves as an emergency backup power source, promptly switching to off-grid mode during external grid failures or curtailments, ensuring continuous power supply to critical equipment and preventing production downtime and associated financial losses. It also continually monitors and optimizes power quality, providing a stable and clean power environment for sensitive machinery. Moreover, the system capitalizes on local peak-to-off-peak pricing policies by implementing peak-shaving strategies, charging during off-peak hours and discharging during peak hours, effectively reducing the company's overall electricity costs and contributing to both economic and environmental benefits.
In summary, GREEN POWER's energy storage solutions, characterized by their integrated design, intelligent management, and diverse operational modes, successfully address challenges related to renewable energy integration, power quality optimization, and utilization of intermittent energy for the three mentioned businesses, fostering efficient energy use and cost-effective operations. These efforts not only contribute to China's dual carbon goals but also represent proactive explorations of sustainable business pathways. Looking ahead, with ongoing advancements in energy storage technology and expanding applications, more companies are poised to benefit from solutions like those offered by GREEN POWER, jointly advancing towards a greener, lower-carbon, and highly-efficient energy era.
