Hearing He Min's explanation, Fang Cheng probably understood the intention of upgrading the national power grid.

The core is to save power.

The traditional copper wire cable is already the most cost-effective material among metals in terms of electrical conductivity and output. However, copper wire still has resistance. When current passes, part of the electrical energy is converted into heat energy and consumed.

Today's high-purity graphene can achieve superconductivity below [-] degrees Celsius, which will have an impact on the power industry.

"Saving electricity is indeed a big thing that needs to be done immediately."

"It is also the fastest and most effective application direction today." Fang Cheng admitted.

When He Min heard Fang Cheng's approval, his face became even more enthusiastic, "Indeed, and the situation is very urgent. It has only been half a year, and our estimated total national electricity consumption this year is expected to increase by another ten to twelve percentage points. .”

"By the end of the year, the total electricity consumption in the country is estimated to reach 22 trillion kwh."

"The coastal manufacturing industry is a big consumer of electricity, and it is expected that there will be power rationing again."

"22 trillion kwh!",

"According to our statistics last year, the national average power line loss is about 22%, and this year it should also be controlled at a similar value, [-]% of [-] trillion kWh."

"One point three-two trillion kilowatt-hours."

"As the chief engineer of the power grid, it is my responsibility to control the loss of electric energy. Every time I think of this figure, I feel pain in my heart."

"And this number, as our country grows stronger, will become more and more."

"It's an inappropriate analogy."

"You know, the largest Qinghe nuclear power plant in Xiaguo, which was put into use just last year, has an installed capacity of 1000 million kilowatt-hours. The annual total power generation, excluding maintenance, overhaul and other time, the total power generation in a year is almost We have just been able to reach 750 billion kilowatt hours."

"Comparing this way, Researcher Fang, you can understand why I am so urgent."

"The annual power consumption can almost directly support [-] million-kilowatt-hour nuclear power plants."

"When converted into coal, it is nearly [-] million tons of standard coal, [-] million tons."

"Today, the total amount of coal we import in a year has only reached more than 4 million tons, and the calorific value of these [-] million tons is not necessarily standard coal."

"And just for these imported fuels, we have to suffer from others to raise prices."

"Every year, our most anxious and most concerned issue is how to minimize circuit loss."

"Even if it can be reduced by [-] percent, [-] percent, that is an incomparably huge resource."

"We have done everything we need to do, including urban circuit reconstruction, high-voltage power transmission and other measures."

"After so many years, we have made a lot of achievements. From the original line loss of more than ten percent, several years ago, it has been controlled to six percent today, and some areas can even reach 5.00%. But Today, it is difficult to reduce it down, and the inherent limitations of materials have made it impossible for us to continue to reduce it."

"The only way to do that is to change the cable material."

"And the three-dimensional macro-scale high-purity graphene released by Researcher Fang in the last press conference, as well as the terrible yield, let us really see hope."

"We got the samples in the past few days and tested them."

"After our calculations and estimates, if we can use this material as the core material of the cable, our power transmission efficiency can control the line loss to about [-]% or even less nationwide! "

"This will be a very large project, but this alone is equivalent to saving [-] million tons of standard coal for our country every year, and the actual savings will be even more."

"And now the price of a ton of coal is [-] yuan, and it will continue to rise in the future."

"One year, we will save nearly two trillion yuan just on fuel!"

"Two trillion!"

"And this cost will only increase with our development in the future."

"If this cost can be reduced, it will be equivalent to our national finance, which will reduce expenditure by two trillion yuan every year and invest it in other fields. I don't know what chemical changes will occur."

"So, although this is a big project, no matter how big the investment is now, as long as it is verified that it is feasible, it will be rolled out immediately."

"And the sooner the better." He Min was full of excitement when he said this.

After Fang Cheng and Chen Fangguo on the side listened, Chen Fangguo was also full of emotion, "I know that the loss of this line will be huge, but I never thought that the consumption in a year would be so large."

"No wonder, among so many people, Lao He and your power department are the most anxious."

"It's me who loses two trillion yuan in vain a year, and I'm also in a hurry."

"Sitting in the seat of the chief engineer, I guess my butt will catch fire every day, and I can't sit down at all."

Hearing Chen Fangguo's approval, He Min nodded heavily, "Who said no?"

"Others can regard the loss of 5.00% as normal and turn a blind eye."

"However, I am not good as the chief engineer."

"The power consumption, which is rising steadily every year, is like a mountain weighing on our hearts."

"But now, there is finally hope. Tell me, can I not be in a hurry?"

"It's not just me, the Electric Power Research Institute I'm in charge of is much more excited than their computer design and construction. If they want to come up with that thing, there are still a lot of obstacles to overcome."

"As for our cable, the main problem is the material. It can basically be used directly."

"And these days, after the preliminary design, if we replace copper wire cables with graphene, the problems we need to face are all minor problems."

"We are here today for two purposes."

"First, on behalf of the State Grid, we want to hire Researcher Fang to be the general consultant for our power grid construction. If we encounter some difficult problems related to materials, we hope that we can find Researcher Fang for timely communication and help."

"The second purpose, because once the plan is officially launched, we will need a very large amount. According to this year's statistics, the total length of power transmission cables in the country is nearly 300 million kilometers. Therefore, I hope that we can reach a strategic cooperation with the Galaxy Future Research Institute. protocol."

"Considering the confidentiality of high-purity graphene, it will not be lost on a large scale. We hope that our State Grid Group and Galaxy Future Research Institute will cooperate to build a factory to provide high-purity graphene cables for our power grid group."

He Min threw out two purposes, which can be regarded as the real core purpose. After finishing speaking, he stared nervously at Fang Cheng.

On the other side, Zhao Xiaoqi's face was flushed red, and she knew that there would be a large amount of business, but it was difficult for her to calculate how much such a big business as the upgrade of the national power grid would be. The length suddenly fluctuated violently, and the factory-strength cables of 300 million kilometers, although this kind of big business, it is impossible to sell at the public price of 300 grams, but even if it is only a few tens, or even ten yuan per gram, the price will go up. , The replacement of 300 million kilometers of transmission lines is also a huge astronomical figure.

This is a big business measured in trillions.
