500 million kWh

In 2020, the new energy generation in Jianshan New District, Haining City, Zhejiang Province will generate more than 500 million kilowatt-hours.

On April 7, a reporter from Science and Technology Daily learned from the Administrative Committee of Jianshan New District, Haining City, Zhejiang Province that the “Source-Network-Load-Storage Integration Demonstration Zone” and the “Green Low-Carbon Industrial Park Construction Demonstration Zone” were recently established in Jianshan, Haining.

Build a new green and low-carbon energy system

"Jianshan New Area adheres to the green and low-carbon development route and takes advantage of its advantages in new energy.

Jianshan New District is dominated by industry.

On February 25 this year, the "Guiding Opinions" proposed: to improve the level of clean energy utilization and the operation efficiency of the power system, and to play a good role in the integration of source, grid, load and storage.

Source network load storage is an operation mode that includes the overall solution of "power supply, grid, load, energy storage", which can accurately control the social interruptible power load and energy storage resources, improve the level of safe operation of the power grid, and solve clean energy Grid volatility and other issues in the process of absorbing.

　　On March 19, Haining City issued the "Guiding Opinions on Promoting the Coordinated Development of Sources, Networks, Loads and Storage to Promote the Efficient Use of Clean Energy" (hereinafter referred to as Haining’s "Opinions"), proposing the establishment of a "new power system with new energy as the main body".

　　According to the requirements of Haining's "Opinions", Jianshan New Area will continue to vigorously develop new energy sources such as photovoltaics and wind, provide policy support to new energy companies, and further promote efficient use of cooling, heating and power, combined heat and power, etc.

　　"Jianshan New District is one of the regions with the earliest start, fastest development, and highest density of new energy such as distributed photovoltaics in my country.

　　Choose Jianshan because of its first-mover advantage

　　"In addition to policy advantages, as an important aspect of building a'new power system with new energy as the main body', Jianshan New District has a first-mover advantage in the construction of a'source-network-load-storage integration demonstration zone'.

　　According to statistics, in 2020, the local new energy generation in Jianshan New Area will generate more than 500 million kilowatt-hours, accounting for more than 30% of the region’s total electricity consumption.

　　"It has the foundation and advantages to carry out the construction of the'source-network-load-storage integration demonstration zone' and the'green low-carbon industrial park' in Jianshan New District.

　　On the local power supply side, there are 97 enterprise photovoltaic power stations in Jianshan New Area; on the power grid side, the Jianshan Power Grid has developed rapidly in recent years, the grid structure has been continuously optimized, and the level of intelligence has been rapidly improved; on the load side, Jianshan New Area is dominated by industry, with 150 companies.

　　In June 2017, the National Energy Administration piloted the "Zhejiang Jiaxing Urban Energy Internet Comprehensive Pilot Demonstration Project" in Jianshan.

　　"Not only must we make good use of new energy, but also enrich the application scenarios and give full play to the value and effect of new energy.
