Recently, the Guangdong Provincial Development and Reform Commission and the Guangdong Provincial Energy Bureau issued the "Several Measures to Promote the Development of New Energy Storage Power Stations in Guangdong Province" (referred to as the "Measures"), which made the energy storage industry boil collectively.

Guangdong is the largest province in the country's economy and the largest province in electricity consumption, but it is also one of the provinces with the largest power "gap" in the country, let's learn about the hot Guangdong industrial and commercial energy storage industry~

The Measures strongly encourage the development of user-side energy storage, and user-side energy storage projects that use user-side energy storage projects that are certified to meet the standards and specifications of advanced high-quality products will be independently metered and implemented in accordance with the cold storage price policy fully implemented by Guangdong Province. Guangdong's cold storage electricity price adopts the peak-flat valley electricity price method, based on the flat section electricity price of the corresponding electricity price category of the user, and the peak-flat valley electricity price ratio is 1.65: 1: 0.25. The electricity price during the trough period is the lowest in the country, and the peak-to-valley difference is the largest.

The area with the largest peak-to-valley electricity price difference in June was Guangdong (the five cities in the Pearl River Delta), which was 1.4279 yuan/kWh. Peak-valley spread arbitrage is the most important business model for user-side energy storage.

As we all know, there are many application scenarios of energy storage systems, including renewable energy grid-on-grid, grid-side peak regulation / frequency regulation, user-side peak-valley arbitrage, etc., in fact, energy storage itself is also a "quasi-financial wealth management product" with high investment value and potential, which can bring investors more fixed, considerable income and returns, and more and more enterprises/individuals are paying close attention.

We have carried out the calculation of the payback period of industrial and commercial energy storage in Guangdong Province, for reference: 

1.Time period division (January-June &10-December)

2. Time period division (July-September, including peak electricity price implementation time)

Combined with the division of peak and valley hours of large industrial electricity consumption in Guangdong Province, the charge and discharge logic is set at the EMS main station, and the PCS accepts the EMS downward command to perform the charging and discharging action, and the daily income is calculated as follows:

★ The first charge and discharge income of the day = (sharp) electricity price during peak hours× discharge power - electricity price during low valley hours× charging power consumption;      

★ The second charge and discharge revenue of the day = (sharp) peak hour electricity price× discharge electricity - weektime electricity price× charging power consumption;

★ The total income of charge and discharge on the day = the first charge and discharge income + the second charge and discharge income.

The electricity price standard calculated this time, taking the industry and commerce of the five cities in the Pearl River Delta in Guangdong Province as an example (the latest large-scale industrial electricity price in June 2023), the peak electricity price is about 1.5114 RMB/kWh, the peak electricity price is about 1.2146 RMB/kWh, the flat section electricity price is about 0.7258 RMB/kWh, and the valley electricity price is about 0.2929 RMB/kWh. The peak-to-valley ratio is: 1.7 : 1 : 0.38.

The product design life of the energy storage system is calculated according to 10 years, the charge and discharge rate is 0.5C, and the plate replacement liquid cooling and heat management technology is adopted, and the system is integrated design. According to the 10-year operation period and two investment methods, the estimated payback period is as follows:

Application scenarios of industrial and commercial energy storage

Since the benefits of Guangdong industrial and commercial energy storage are considerable, what are the application scenarios of industrial and commercial energy storage? How to reduce electricity costs through energy storage systems and realize value such as peak-valley arbitrage? Here, six typical application scenarios of industrial and commercial energy storage are listed:

1. Distributed new energy  2. Microgrid   3. Big Data Center  4. 5G base station  5. Charging facilities  6. Industrial Park

【Scope of applicable enterprises】1. General industrial and commercial enterprises that implement the peak-valley equal time-sharing electricity price 2. The electricity consumption in each period has a certain volatility 3. The number of operating days > 330 days 4. The average value of the peak-valley price difference and the peak-to-valley price difference is ≥ 0.65 yuan/kWh5, and the annual electricity consumption is > 5 million kWh

Kortrong energy storage empowers the tens of billions of industrial and commercial energy storage market

It is believed that under the vigorous promotion of the "Measures", more and more investors/owners will build Guangdong industrial and commercial energy storage projects.

Kortrong energy storage industrial and commercial energy storage solutions, through the whole industry chain products and services independently developed by Kechuang, can easily achieve peak shaving and valley filling, reduce the electricity cost of enterprises and parks, improve the level of distributed energy consumption, reduce the impact of "power cuts", increase the usable capacity of transformers, and solve the "power anxiety" of industry and commerce.
