Energy Storage Knowledge Class| C&I Application Scenarios: Industrial Park + Energy Storage
With the continuous advancements in energy storage technology and the decreasing prices of lithium batteries, the cost of battery energy storage systems (ESS) is gradually decreasing, which highlights the increasing economic viability of battery energy storage applications in the commercial and industrial (C&I) sectors.. According to relevant data, the annual average growth rate of global C&I energy storage from 2021 to 2023 reached 169%.
As one of the major consumers of energy, industrial parks often face the burden of high electricity costs. Additionally, they can suffer significant losses during power outages caused by grid overloads or other failures. In recent years, under the global consensus on "carbon reduction," many countries and regions have increasingly deployed renewable energy in their industrial parks. For example, solar panels are installed on rooftops or on the ground to generate power for park use. However, the power generation from these renewable sources is susceptible to seasonal and weather variations, resulting in volatility and uncertainty. This prevents renewable energy from reliably and consistently replacing traditional energy sources in providing a stable power supply to industrial parks.
Next, this article will discuss one of the typical application scenarios for C&I energy storage: Industrial Parks + Energy Storage.
Q
What is Industrial Park + Energy Storage?
A
As literally understood, Industrial Park + Energy Storage refers to deploying such energy systems within traditional industrial parks to address their specific energy needs and challenges. Traditional industrial parks typically feature a large number of equipment characterized by high power consumption, prolonged periods of high-load operation, and high energy consumption. Implementing ESS can help industrial parks balance electricity supply and demand, effectively manage energy fluctuations and peak-demand variations, ensure stable power supply, and optimize energy utilization efficiency.
Q
What are the prerequisites for configuring energy storage in industrial parks?
A
Time-of-Use (TOU) Tariff Policy: Industrial parks must adhere to local TOU tariff policies, with a significant price differential between peak and off-peak hours (recommended at least RMB 0.8 yuan /kWh in China). The larger the price difference between peak and off-peak electricity, the higher the returns for industrial park ESS that primarily rely on peak-valley arbitrage for their profitability.
Coverage of High-Load Periods: The electricity consumption pattern of users should cover peak periods. If electricity is primarily used at night, it may not be suitable for implementing an ESS.
Transformer Surplus Capacity of Transformers: During off-peak and normal load periods, there should be surplus capacity in transformers to accommodate charging of the ESS. If the transformer load rate in the park is high, it may not be feasible to install an ESS.
Annual Utilization Time of ESS: The system should be operational for more than 270 days annually to ensure its long-term stability and economic viability.
Q
What are the advantages of building ESS in industrial parks?
A
Cost Savings
Storing electricity during off-peak periods when prices are low and utilizing stored electricity during peak periods when prices are high, the peak-load shifting can significantly reduce electricity costs for industrial park enterprises.
Improve Power Quality and Stability
（1）Reduce Grid Pressure: Alleviating peak electricity demand during high-load periods within industrial parks, especially during daytime peaks for manufacturing enterprises. ESS can provide electricity during peak demand, reducing reliance on the grid and helping balance grid loads.
（2）Emergency Backup Power: During grid failures or power outages, ESS can serve as emergency power sources, ensuring continuous operation of critical equipment and systems in industrial parks.
Enhance Renewable Energy Utilization
（1）Optimize Energy Use: For industrial parks equipped with renewable energy, ESS can store surplus electricity generated from renewable sources such as solar and wind within industrial parks, smoothing power output and reducing waste, maximizing the utilization of renewable energy .
（2）Reduce Carbon Footprint: By increasing the efficiency of renewable energy utilization, industrial parks can reduce reliance on traditional fossil fuels and decrease their carbon emissions, promoting sustainable development.
Improve Energy Efficiency
（1）Capacity Management: ESS capacity management refers to the systematic planning, allocation, scheduling, and optimization of the system's capacity using scientific methods and technological tools. The goal is to ensure the system efficiently meets electricity demand while maximizing effectiveness and benefits. This involves utilizing historical electricity usage data and operational data from the storage system to analyze trends in e

Energy Storage Knowledge Class | Global C&l Energy Storage Revenue Models
According to data released by the China Chemical and Physical Power Industry Association, the global commercial and industrial (C&I) energy storage market is expected to see an additional installed capacity of 11.5 GW by 2025. By then, the cumulative market size for global C&I energy storage is projected to reach RMB 19 to 24 billion yuan. However, in 2023, the newly added capacity for global C&I energy storage was only 1.8 GW. This indicates that the global C&I energy storage market will continue to experience explosive growth over the next two years.
For instance, in Europe, according to the TD Times Energy Storage Database's "2024 Global Energy Storage Industry Trend Forecast Report," the number of C&I enterprises exceeded 23 million in 2022. Assuming that 25% of these enterprises can install photovoltaic (PV) rooftops, the penetration rate of C&I PV storage is only 0.53%, and the penetration rate of C&I energy storage is even lower at 0.08%. This highlights the vast market potential for C&I energy storage in Europe.
The rapid development of C&I energy storage cannot be separated from its increasingly evident advantageous revenue models. It also requires active exploration by enterprise users and social capital to discover broader profit avenues, continuously enhancing the efficiency and benefits of C&I energy storage.
Currently, considering the major markets for global C&I energy storage, which include China, the United States, Japan, and Europe (with Germany as a representative), the primary revenue models for C&I energy storage are as follows:
01 Direct Subsidies
The revenue model of direct subsidies exists in several countries. For instance, in China, 10 provinces and 31 regions have introduced subsidy policies for C&I energy storage. These subsidies are primarily based on discharge volume, capacity, and investment. Additionally, in April 2023, the United States implemented the IRA Act, which includes the ITC (Investment Tax Credit) policy, providing significant subsidies for C&I energy storage.
02 Peak-load Shifting
Peak-load Shifting is the most common profit model for C&I energy storage, especially prevalent in many Chinese installations where it serves as the primary revenue source.
This model involves commercial and industrial users charging energy storage systems at lower off-peak electricity rates, storing electricity for later use. During peak or high-demand periods, the stored energy is discharged to supply the load, thereby reducing electricity costs, mitigating potential power interruptions due to grid constraints such as load shedding.
03 Demand-side Management
Demand-side management is also a common profit model in China's C&I energy storage sector.
Demand-side management controls the need for loads, ensuring that the maximum power required by a business does not exceed the contracted electricity capacity. Currently, the two-part tariff system includes electricity charges and basic fees. Basic fees are calculated in two ways: one based on the capacity of operational transformers, and the other based on the maximum demand recorded monthly by the electricity meter. Installing energy storage systems can reduce peak loads for customers, lower demand values, and thereby reduce capacity-related electricity charges for customers.
04 Energy Shifting
Photovoltaic (PV) combined with energy storage represents a typical scenario of energy shifting, widely applied in markets across China, the UK, Germany, and various parts of Europe.
Energy shifting in C&I energy storage refers to the process of storing electricity generated from renewable sources like solar and wind in storage systems and releasing it when needed to supply specific loads or the grid.
Due to the intermittent nature of solar photovoltaic (PV) generation, which depends on weather conditions, its electricity production fluctuates. When a PV system generates more electricity than is needed by C&I users, the excess electricity is sold to the grid at lower prices. Conversely, when sunlight is insufficient, businesses must purchase electricity from the grid at higher prices, leading to fluctuating energy costs.
By deploying energy storage systems, C&I users can store surplus electricity during periods of high PV output that exceeds their immediate needs. This stored energy can then be discharged from the battery storage system during times of insufficient PV generation to meet electricity demand. In this way, energy storage acts like an intelligent scheduler, smoothing out the supply and demand of electricity, increasing PV generation and integration rates, and ultimately maximizing cost savings on electricity consumption.
05 Demand Response
In the United States, the electricity market environment is highly open, currently leading globally in the number and variety of demand response programs implemented. In Northern Euro

Fire Drill | Vilion Actively Responds to the“Safety Production Month”
This June marks the 23rd National "Safety Production Month" in China, with the theme "Everyone Speaks Safety, Everyone Knows Emergency Response - Keep Life Channels Open." On June 28, 2024, Vilion conducted a fire drill at its Shenzhen intelligent factory for all employees. The drill aimed to enhance employees' safety awareness and sense of responsibility, emphasizing the importance of safety in production, equipping them with personal protection skills, and ensuring safety in both work and life.
The fire drill at Vilion Shenzhen intelligent factory was led by the Factory Director Mr. Wang. A professional safety consultant was invited to educate all employees on fire safety. The employees were also organized into six groups: Emergency Command, Rescue, Evacuation, Medical Aid, Communication, and Logistics Support. Then, they participated in a fire evacuation drill and were trained on the correct use of fire extinguishers, fire blankets, and other firefighting equipment, which emphasized the importance of safety and enhancing their safety awareness and first aid skills.
The invited safety consultant, who possesses extensive knowledge in safety and first aid experience, demonstrated the CPR (cardiopulmonary resuscitation) process on-site and taught the key points step by step. If you encounter someone experiencing sudden cardiac arrest in daily life, please follow these steps for rescue:
1、Assess the Scene
The first step, evaluate whether the scene is safe. Only when the environment is secure should you approach to assist the patient.
2、Check for Responsiveness
The second step, gently tap the patient's shoulders and loudly ask, "Hey, hey, are you okay?" to determine if there is any response.
3、Call for Help
The third step, if there are bystanders, instruct someone to call emergency services (120) and get an Automated External Defibrillator (AED) if available. If you are alone, call 120 yourself while beginning resuscitation efforts. If you don't have a phone, find one quickly and return to provide aid.
4、Check for Breathing
The forth step, look directly at the patient’s chest (after removing thick clothing) to see if there is any movement indicating breathing. The assessment should take 5-10 seconds, using “look, listen, and feel” techniques—watch the chest, listen for breath sounds, and feel for breath airflow.
5、Perform CPR
The fifth step, place your hands on the center of the patient's chest (on the sternum between the nipples) and perform hard (at least 5 cm deep) and fast compressions (100-120 times per minute) 30 times. Then open the patient’s airway and provide rescue breaths. Cover the patient’s mouth with yours, take a calm breath, and blow until you see the chest rise. Give 2 rescue breaths. Repeat this cycle of 30 compressions and 2 breaths for 5 cycles.
6、Reassess
The sixth step, after every 5 cycles of 30 compressions and 2 breaths, reassess the patient's consciousness and breathing. If there is improvement, stop CPR. If there is no improvement, continue until trained help or emergency personnel arrive.

Energy Storage Knowledge Class: Differences Between C&I Energy Storage and Large-Scale Storage
Currently, the global generation of renewable energy is continuously increasing. However, due to its significant variability, it is challenging to ensure a stable supply. The application of energy storage technology provides an effective solution to this issue, garnering attention from countries worldwide. Various policies have been introduced to promote the development of energy storage. For instance, the United States has implemented the Investment Tax Credit (ITC) for energy storage, Europe has introduced the Green New Deal, and various local governments in China have developed energy storage plans. These measures have positively contributed to the growth of the energy storage market.
According to the IEA (International Energy Agency), to facilitate the rapid deployment of new solar PV and wind power that is necessary to triple renewables, global energy storage capacity must increase sixfold to 1500 GW by 2030. Batteries account for 90% of the increase in storage in the Net Zero Emissions by 2050 (NZE) Scenario, rising 14-fold to 1200 GW by 2030. Battery energy storage shows great potential in the global energy storage sector.
Energy storage can be categorized based on application scenarios into power generation-side, grid-side, and user-side storage. Power generation-side and grid-side storage are also known as front-of-meter storage or large-scale storage, while user-side storage is referred to as behind-the-meter storage. User-side storage can be further divided into commercial and industrial (C&I) storage, and residential storage. Large-scale energy storage currently holds the majority market share globally. However, in the past two years, C&I energy storage has been gaining significant traction. In 2022, the global growth rate for C&I energy storage was only 14.58%, but by 2023, the newly installed capacity reached 1.8GW, marking a 115% year-over-year increase. The major markets for global C&I energy storage are concentrated in China, the United States, and Europe (with Germany being a notable representative). Vilion has focused on the R&D, production, sales, and service of C&I battery storage technology and products since its establishment in 2019.
