New energy storage industry promotes green and low-carbon development - storage electric home energy

Learned: In December, seven energy storage devices and 12,000 square meters of photovoltaic power generation facilities in the factory of Chongqing Qinglan Industrial Co., LTD., can provide 6,000 kilowatt hours of electricity per day, making the company self-sufficient in electricity used in production.

"Each of the seven energy storage devices in the plant of Kyungran Industrial can store 430 KWH of electricity in two hours after being charged in the valley and flat. These energy storage devices are self-contained, balance on-grid mode, giving priority to the plant." Zhang Yongbing, head of the energy storage development project department of Haichen Energy Storage Technology Co., LTD., said that the 3680 photovoltaic panels laid on the roof of Qinglan Industrial Company constitute 12,000 square meters of photovoltaic power generation facilities. Together with energy storage equipment, they form the "optical storage integration" system, which effectively improves the enterprise power grid regulation, new energy consumption and emergency power supply protection ability.

Chongqing Tongliang District accelerated the construction of a demonstration area for the development of new energy storage industry, built a new energy storage industry cluster with Haichen Energy Storage as the leading, developed application scenarios of new energy storage products, and promoted the green and low-carbon development of the economy.

"Energy storage takes advantage of the electricity price difference between peak-valley segment and peak-flat segment, and adopts the two-charge and two-discharge mode of valley charging peak discharge and flat charging peak discharge. Photovoltaic part generates about 1.26 million KWH of electricity every year, and photovoltaic energy storage saves nearly 2.57 million yuan of electricity cost for enterprises every year on average." Zhou Keyu, a specialist in new energy management at the Marketing Department of State Grid Copper Beam Power Supply Company, said that the energy storage station acts as a backup power supply in case of emergency, which can guarantee the power supply in time, ensure the normal and continuous power supply of security loads, and avoid product quality damage.

In Shaoyun Village, Shaoyun Town, hometown of revolutionary model Qiu Shaoyun martyr, the largest mountain photovoltaic power plant in western Chongqing was put into use last month. As a red "zero carbon" beautiful village construction project, the power plant and the utility transformer in Shaoyun Village are equipped with energy storage equipment with a total capacity of 2,000kW / 3,665 KWH, which can smooth the fluctuation of daily power supply and demand and effectively improve the power quality of rural residents' lives.

"Tongliang actively develops application scenarios of all kinds of new energy storage products on the power supply side, the power grid side and the user side, and makes a demonstration on enhancing the safety and stability of the city's electric power system to accelerate the marketization and large-scale development of new energy storage." Tongliang District economic and Information Commission director Chen Yu said.

At present, Tongliang District has launched a number of measures to promote the development of new energy storage, support the integrated development mode of "new energy + energy storage", and promote the development of new energy storage at the user side; We will encourage new and existing centralized photovoltaic power stations, waste incineration power stations and other new energy power stations to build supporting new energy storage facilities. Power generation enterprises that build new energy storage facilities with a matching capacity of 10% or more of the number of units installed in power stations will be given an annual subsidy of 5% of the investment in building new energy storage facilities for four consecutive years.

"Around the leading enterprises, we focus on building the whole industrial chain from research and development to scene application of energy storage batteries, realize the local supporting and cluster development of the industrial chain, build the industrial ecosystem, and accelerate the 'lane change and overtaking' of the new energy and new materials industry." Chen Yu said that it is expected that by 2025, Tongliang will have more than 100 enterprises in the new energy storage industry chain, and the output value of the new energy storage industry in the demonstration area will exceed 100 billion yuan, which will radiate the formation of 200 billion level new energy storage industry cluster in the city, and accelerate the green, low-carbon and intelligent development of the industry.
