The core advantages of industrial energy storage systems include peak shaving and valley filling to reduce electricity costs, improving power supply reliability, promoting the consumption of renewable energy, participating in grid demand response, and enabling dynamic capacity expansion.
Peak shaving and valley filling to reduce electricity costs: Energy storage systems charge during off-peak hours (such as nighttime) and discharge during peak hours (such as daytime), utilizing the peak-valley price difference to achieve arbitrage and significantly reduce electricity expenses for enterprises. For example, a manufacturing plant in Xinxiang saved approximately 410,000 yuan annually in electricity costs through a photovoltaic-energy storage project
Improving power supply reliability and power quality: In the event of grid failures or sudden power outages, energy storage can seamlessly switch as a backup power source, ensuring the continuous operation of critical equipment (such as production lines and data centers) and preventing production interruptions and equipment damage. Simultaneously, energy storage can smooth voltage fluctuations, filter harmonics, and improve power quality, meeting the needs of power-sensitive industries such as semiconductors and precision manufacturing.
Promoting Renewable Energy Utilization: Energy storage can be used in conjunction with renewable energy sources such as photovoltaics and wind power to store electricity generated during periods of surplus and release it during periods of insufficient generation or peak demand, thus solving the "generation-demand mismatch" problem, increasing the self-consumption rate of green electricity, and supporting enterprises' green transformation.
Participating in Grid Demand-Side Response: Energy storage systems can respond to grid dispatch instructions and discharge electricity into the grid during periods of power shortage, participating in ancillary services such as frequency regulation and peak shaving, obtaining additional economic compensation, with returns even exceeding those from peak-valley arbitrage.
Achieving Dynamic Capacity Expansion (Virtual Expansion): For older plant areas with insufficient transformer capacity, energy storage can discharge during peak demand periods, alleviating transformer overload pressure, delaying or avoiding costly power capacity expansion and renovation, and saving on distribution system upgrade costs.
