Why energy storage?
Deal with peak-to-trough differences in energy demandEnergy storage equipment can store excess energy during peak energy demand and release energy when demand is low, balancing energy supply and demand, and reducing energy costs for enterprises.
Improve energy efficiencyEnergy storage equipment can convert electrical energy into other forms of energy storage, such as chemical energy, mechanical energy, etc., to improve energy efficiency.
Respond to grid fluctuations and failuresEnergy storage devices can be used as a backup power source to provide emergency power in the event of a grid failure or power outage** to ensure the normal operation of the business.
Supporting the development of renewable energyEnergy storage devices can solve the problem of intermittency and instability of renewable energy, store excess renewable energy for use when needed, and promote the large-scale application of renewable energy.
Who needs energy storage?
Large electricity consumers, especially high-energy-consuming enterprises, have a large amount of electricity consumption and a high proportion of electricity expenses, so equipped with energy storage can not only greatly save electricity bills, but also use the peak-to-valley price difference to obtain the income of the charging and discharging price difference. In addition, the purchase of electricity by high-energy-consuming enterprises** is 1 for general users5 times, the cost of electricity has increased significantly. From the perspective of industries, petroleum, chemical, metallurgy, electronics, steel, cement, electrical, papermaking, glass, textile and other industries are usually considered to be industries with high energy consumption. Judging by the electricity consumption,The monthly electricity consumption of the enterprise is at least more than 40,000 kWh, which is suitable for the installation of an energy storage deviceWhich areas are suitable for energy storage?
According to the latest peak-to-valley spread in December 2023, a total of 24 regions have a peak-to-valley spread of more than 07 yuan kWh (including 1.)5 times), while the spread is generally considered to be more than 0Provincial energy storage projects of 7 yuan kWh are economical. In addition to the electricity price spread,Areas with multiple peaksEnergy storage can be achievedNumber of charge and dischargeThe more, the more room to make a profit. Zhejiang, Hubei, Hunan, Shanghai, Anhui, Guangdong, Hainan and other provinces and cities have set two peak periods for time-of-use electricity prices every day, which can achieve two charging and discharging, and is suitable for energy storage. What is the income from allocation?
At present, the specification of energy storage equipment of Constant Energy is 100kW 233kWh, and the total construction cost is temporarily 165 yuan Wh, so the construction cost of a single piece of equipment is about 380,000 yuan. The figure below shows the first-year earnings and 15-year internal rate of return (IRR) of an energy storage device in some provinces across the country.
Through the calculation, it can be seen that Zhejiang, Guangdong, Shanghai and Jiangsu are the most important or most suitable positions for industrial and commercial distribution, with an IRR between 12% and 21%. Due to policy reasons, it is difficult to achieve industrial and commercial distribution and storage in Shanghai. How do enterprises configure it?
