Is the Jilin Provincial Water Resources Service Center a provincial unit?

The Jilin Provincial Water Resources Service Center is a provincial unit. According to the request for relevant public information, the Jilin Provincial Water Resources and Service Center is an institution directly under the Jilin Provincial Water Resources Department and a provincial unit whose responsibilities are responsible for monitoring, forecasting and disclosure of information on water resources. supervision of water conservation, water and soil management projects in Jilin province. Keep working on things like this.

The people of Jilin Province are blessed.

Why do you say that? Indeed, Unit 1 of the Jilin Dunhua Pumped Storage Power Plant, which serves as a voltage stabilizer for the electricity grid and clean energy storage, was officially put into operation on June 4, 2021.

This pumped storage power plant is in effectfet very powerful, because it is the first pumped storage power plant in China with a water level difference of 700 meters. The maximum height reaches 712 meters, which is 10 times the height of Huangguoshu Falls. It is the tallest pumped storage power plant built in China.

What is a pumped storage power plant?

A pumped storage power plant is a hydroelectric plant that uses electrical energy during periods of low load to pump water to the upper reservoir and then releases water to the lower tank to produce electricity. during peak power load periods. Also known as a hydroelectric energy storage plant.

It was the emergence of pumped storage power plants more than 130 years ago that solved the problem of the inability to actually store electrical energy.

So when some people see the image above, especially the phrase “draw four and three”, they must have questions? The heart of the question must be that this is obviously a compensation agreement? This is equivalent to “water in the head”.

People who have this kind of doubt ignore a fundamental fact: they have not noticed at all that the electrical energy used to pump the water is the excess electrical energy when the network load electricity is low (some people also refer to this type of excess energy as electricity, called "wasted electricity") into high-value electricity during peak grid hours.

This kind of excess electrical energy, if not used, will be wasted in vain, which should be a high probability event.

Principle of energy storage of a pumped storage power plant

ThePumped storage belongs to physical energy storage and currently constitutes the largest installed capacity. Apply the most mature energy storage technology. A pumped storage power plant is a hydroelectric plant that uses excess electrical energy to pump water to the upper reservoir when the electrical load is low, converting the electrical energy into the potential energy of the water, and then releases water to the lower reservoir to generate electricity during the peak electrical load period, converting potential energy back into electrical energy.

First, it reduces nearly 870,000 tonnes of carbon dioxide emissions each year, which further improves the human living environment.

Second, improve the Jilin Power Grid's ability to absorb new energy. Annual consumption of clean energy such as wind and light powerneuse has exceeded 5 billion kilowatt hours. This greatly avoids wasting traditional and new energy.

Third, it can reduce the annual coal consumption of thermal power plants by 450,000 tons. On the one hand, this reduces the overexploitation of underground mineral resources. On the other hand, it indirectly reduces the direct damage caused by the emission of toxic and harmful gases such as carbon monoxide, carbon dioxide and sulfur dioxide from burning fuels into the atmosphere, causing damage direct to the environment on which humans depend for their survival. .

Of course, the benefits go far beyond these. Because it is expected that by the end of 2025, the installed capacity of new energy will reach 35 million kilowatts, accounting for 54% of the total installed capacity of Jilin Province. By then, new energy production will becomehas the largest energy source in Jilin province.
