Chapter 155 155 Power Gaps and Thermoelectric Materials

Wang Feng really didn't have a good rest last night, so after giving these instructions, he went back to the small cubicle in his office to rest. After this sleep, he didn't wake up until the afternoon.

After Wang Feng woke up, Jin Lili delivered the food. Wang Feng hadn't woken up when he was eating at noon, so Jin Lili made a portion for him after eating.

It's just that not only Jin Lili came here, but Director Lu of the Energy Bureau also came, which made Wang Feng a little curious.

"Director Lu, why are you here?" Wang Feng asked curiously, stood up at the same time, first shook hands with the other party, and then took the food that Lily brought him.

"I need to ask you for some things, but you should eat first, so as not to get cold later." Director Lu sat down, as if I was not in a hurry.It doesn't look like it's already the third trip here.

"Okay then, I'll trouble you to wait a little longer, I'm really a little hungry now." Wang Feng didn't have any politeness, put Director Lu aside, and started cooking wholeheartedly.

"Even if you are busy at work, you should pay attention to your health!" Director Lu advised, "Although you are still young, you should also pay attention to maintenance. Like last night, don't do things like staying up late. After all, the days are still long. Now, only by maintaining a good body can we better contribute to the construction of the country."

"I know, I will pay attention!" Wang Feng was embarrassed to say that he had insomnia last night, so he could only say vaguely.

After Wang Feng finished eating, Director Lu said anxiously: "You should already know what happened yesterday, right?"

"What happened?" Wang Feng frowned and began to recall, did he miss some important event when he went to his father-in-law's house yesterday?
"It's about the power outage, didn't you know this morning?" Director Lu asked.

"So that's what I was talking about. I thought it was something." Wang Feng breathed a sigh of relief, but after thinking about it, this kind of thing should not disturb a person of Director Lu's level, right? What details didn’t you notice?

Director Li is such an experienced person. He knew as soon as he heard that Wang Feng had not paid attention to this matter at all. He had no idea that the power restriction order had caused a great reaction in society, especially in this hot summer. .

"You should take a look at this thing first!" Director Lu had already prepared, he took out a dozen documents and handed them to Wang Feng: "After reading this, you will know what happened recently Son."

""Beijing City Summer Orderly Power Consumption Plan"?" Wang Feng took the document from the other party's hand, flipping through it with a confused face: "Why did you give me this thing, I am not in charge of import and export and production capacity planning, I I can't handle this either!"

Although there are a lot of things mentioned in the document, but to sum it up, it is nothing more than two points: the first is industrial electricity consumption, the capital city and the counties and cities around Jingcheng will use electricity at staggered peaks, and everyone will plan it together time, stagger the peak period of electricity consumption, and reduce the load on the grid.

The second is the electricity consumption of residents. Although this part should occupy a relatively small share, it should not have any impact.However, for an international metropolis like Beijing, due to its high population density, not only the industry consumes a lot of electricity, but also the household electricity consumption and the tertiary industry consume a lot of electricity, so the electricity load in these areas is also very high. big.

Especially for this economic, political, cultural, and technological center, you can't limit the electricity in many places, so this has caused the current situation.

"Director Lu, you're not kidding me, are you?" Wang Feng looked at the other party in shock. You know, for so many years, we have been shouting to cut production capacity and eliminate outdated production capacity. Now you tell me, say Not enough electricity?

"Well... There are many factors to this problem. If it is just to reduce production capacity, it will not lead to this result. After all, everyone still knows that they will not destroy the Great Wall themselves and will leave enough Power plants come to generate electricity. But the problem is not with us, but with foreign countries and natural disasters."

Next, Director Lu explained the secret behind this.

According to the three reasons that the National Development and Reform Commission responded on December 2020, 12, the first is that the rapid recovery of industrial production drives the growth of electricity consumption.The second is to encounter extremely cold weather, which will further increase the electricity load.Third, it is difficult to maintain power supply due to limited external power receiving capacity and increased unit failures.

The first reason is easy to understand. In the context of my country's stable epidemic situation and rapid economic recovery, exports have grown rapidly.According to data released by the General Administration of Customs on December 12, in November alone, China's foreign trade import and export reached 7 trillion yuan, an increase of 11%.Among them, exports were 3.09 trillion yuan, an increase of 7.8%; imports were 1.8 trillion yuan, a decrease of 14.9%.The export trend is strong. In just a few months, the growth rate of my country's industrial added value has become positive, which has directly led to the growth of industrial power generation above the national scale.

The second reason was revealed at the Climate Prediction Conference organized by the National Marine Environment Forecasting Center of the Ministry of Natural Resources in November.Jia Xiaolong, deputy director of the National Climate Center, said at the time that according to predictions, the La Niña state will peak this winter and then begin to decline.This means that in the winter of La Niña years, the temperature in most parts of central and eastern my country is generally lower than that of the same period in normal years.

And indeed it is.Affected by the strong cold air, the temperature in Hunan, Jiangxi and other places is abnormally low this winter.What's more unfortunate is that heating in these areas is dominated by electricity, which further aggravates electricity consumption.According to data from the Power Dispatching Control Center of State Grid JX Provincial Electric Power Co., Ltd., affected by the first cold wave this winter, the Jiangxi Power Grid’s unified power consumption load reached 2547.5 million kilowatts, and the dispatched power generation and receiving power reached 2631.1 million kilowatts, both hitting record highs.

After a long winter of consumption, the ensuing problems have become highlighted: Since the proportion of thermal power generation in our country still accounts for more than 75%, this has resulted in a large amount of coal for power generation being consumed after a winter, resulting in power generation Insufficient coal storage;
At the same time, the price of thermal coal has increased significantly. Last winter, thermal coal had risen from more than 600 yuan to more than 800 yuan. In May of this year, it even began to rush towards the 5 yuan mark.

There is a baseline for power plants to use coal for power generation. Once the price exceeds 640 yuan, the power plant will be unable to bear this price, and even start to pay for it to start generating electricity, because thermal coal can increase in price, but they cannot. price…

"Although I am also worried about this issue, there seems to be nothing I can do here?" Wang Feng was still at a loss after hearing this.

"Although the price of thermal coal cannot be lowered in a short period of time, we can find ways to improve its utilization efficiency, Professor Wang, we need your help on this point!" Director Lu said excitedly.

"Can you go into more detail?"

"Recently, we have seen the latest foreign scientific research results. According to which paper you published, they have successfully advanced the thermoelectric materials to the level of 6, and the energy conversion efficiency at 260 ° C has reached the level of 16%. Do you understand what I mean?"
