the other side.

The boss of Dongtang Power Grid, who was originally scheduled to come for an inspection on January 3, changed the time to January 10 due to unexpected circumstances.

The Raytheon Group didn't have any objections, because their president Fang Shengjie was currently litigating at Mi Li's house.

Huang Junjie could only entertain the boss of Dongtang Power Grid in person.

Huang Haojie took Du Lidao, the boss of Dongtang Power Grid, to the Jushi Bay in Lucheng, Shanmei, where the first wind power station just completed by Haifeng Wind Power Company was built.

Fifty huge vertical wind turbines are running rapidly at this time.

These large wind turbines with a power generation of up to 1,500 kWh can generate 50,000 to 60,000 kWh in one hour.

Du Lidao looked at the wind turbine that was running at high speed and asked the wind power expert who was following him:

"Gong Zhang, how efficient are these wind power plants?"

Perhaps because he often works outdoors, this Zhang Gong’s skin is rough and dark. He said very excitedly:

"Mr. Du, it's really amazing. I just calculated the overall efficiency of their fans, and it actually reached 48-50%. It's simply a miracle."

After listening to Zhang Gong's explanation, Du Lidao, as the boss of Dongtang Power Grid, knew a lot about these power generation methods.

He knows that the comprehensive efficiency of the most powerful vertical wind turbines currently on the market is around 20%, while horizontal wind turbines are theoretically around 50% and actually around 30%.

However, considering the cost of horizontal wind turbines, vertical wind turbines have come back. The cost per kilowatt of a horizontal wind turbine is about 3,000 to 4,000 Chinese yuan; the cost per kilowatt of a vertical wind turbine is about 2,000 Chinese yuan.

After thinking for a while, Du Lidao asked Huang Junjie on the side:

"Mr. Huang, what is the cost or selling price of your fan?"

Perhaps considering that it was inappropriate to ask directly about the cost, Du Lidao asked about the selling price instead.

"At 5,000 Chinese yuan per kilowatt, a large wind turbine with a power of 1,500 kilowatt-hours costs 7.5 million yuan. A wind turbine can generate about 10 million kilowatt-hours a year, and the money can be paid back in about three years." Fang Ping answered quickly. road.

After listening to Fang Ping’s explanation, Zhang Gong from Dongtang Power Grid asked:

"Repay the capital in three years? Is it in the rich area?"

Fang Ping quickly shook his head and explained:

"No, it is in a richer area. If it is in a rich area, it may not take about three years. If it is in a usable area, it will be about four or five years! This data is calculated based on the Shanmei Stone Bay. After all, the wind energy here is about somewhere between more abundant and available.”

"In that case, your starting wind speed should be very low." Experts are experts, and Mr. Zhang immediately asked the key points.

Fang Ping nodded: "That's right, the starting wind speed of our Haifeng 2 wind turbine is 1.2 meters per second."

Du Lidao on the side calculated that if a wind turbine with a power of 1,500 kWh could really generate 10 million kWh of wind power a year, there would be great potential.

"Mr. Huang! Can you check your generator system?"

Huang Haojie nodded: "Okay!"

“Gong Zhang, please take a few people to have a look!”

Hearing Du Liguo's words, Zhang Gong suddenly became excited. After all, for a wind power expert, being able to personally come into contact with this cross-era product is like a gourmet encountering a rare delicacy.

He quickly took a lot of instruments and four or five National Grid staff and headed for the nearest wind turbine.

In order to prevent them from understanding the situation of the wind turbine, Zhang Haifeng and other engineers from Haifeng Wind Power also followed.

Zhang Gongzai carefully checked various data of the wind turbine, including on-site wind speed, blade surface area, volume, weight, generator output power, etc.

After more than an hour of testing, we finally got data that was similar to Haifeng Wind Power.

After handing the report to Du Lidao, he kept saying things like "It's true, I really can't believe it." Apparently he was shocked by the performance of the Haifeng 2 wind turbine.

Du Lidao couldn't help but squint his eyes as he looked at the report in his hand. A 1,500-kilowatt-hour wind turbine costs 7.5 million yuan. Including supporting facilities, the total cost is about 9 million yuan. Based on the current wind power on-grid electricity price per kilowatt-hour. Calculated at 0.3 Chinese yuan, it can really pay back in almost three years.

But he is more interested in Thor's modified batteries.

"Mr. Huang, your wind power technology is unquestionable."

After saying that, Du Lidao gave a thumbs up and then said:

"Mr. Huang, let's go take a look at your power storage station!"

"No problem! Please follow me!"

Huang Junjie led Du Lidao and his party into the power storage station of the No. 1 Calculus Bay Power Station.

Rows of twenty-meter-high reinforced concrete bungalows appeared in front of everyone.

"Mr. Du, this is the power storage station area of ​​the No. 1 Power Station. Each power storage warehouse has a thousand tons of Thor's modified batteries. There are a total of thirty power storage warehouses. Of course, due to the production problems of Thor's modified batteries, temporarily We are only equipped with three power storage bins.”

Huang Haojie introduced as he walked.

"How much electricity can be stored in a power storage warehouse or a thousand-ton Thor modified battery?" Du Lidao asked quickly.

"A power storage warehouse can store 240,000 kilowatt-hours of electricity. Of course, the power in the power storage warehouse is only for the convenience of dispatch. Only a part of the power generation capacity of the power station is stored here."

Du Lidao nodded. Of course he knew that the role of a power storage station was not to store electricity, but to regulate the uneven distribution of electrical energy in space and time.

Last year (2016) Dongtang's annual power generation was 6.14 trillion kilowatt hours, with an average daily power generation of 17 billion kilowatt hours.

It is only necessary to establish a power storage station with a storage capacity of about 5 billion kilowatt hours.

In this way, during the low periods of electricity consumption, excess electricity can be stored in the power storage station, and during peak periods of electricity consumption, electricity can be transferred from the power storage station.

Doesn't this seem like a superfluous move?

In fact, this can save a very large amount of electric energy and reduce a very large installed power generation capacity.

Dongtang generates 17 billion kilowatt hours of electricity a day, which means it needs an installed power generation capacity of up to 800 million kilowatts.

In fact, Dongtang’s national power generation installed capacity in 2016 was 1.5 billion kilowatts.

The main reason why this situation occurs is that there are more than 300 million kilowatts of wind power and photovoltaic power. These unstable power sources must be matched with thermal power stations of similar capacity to regulate.

Otherwise, one-third of the country's electricity consumption will be seriously affected, judging from the intermittent and intermittent power generation of wind power and photovoltaic power.

It is precisely the instability of wind power and photovoltaics that leads to the fact that although the country has a total installed capacity of 1.5 billion kilowatts, the utilization rate is only about half.

If the use of power storage stations is promoted, the domestic installed power generation capacity can be reduced to about 1 billion kilowatts, which can meet the normal needs of the country.

After visiting for more than three hours.

Du Lidao, still unfinished, began to calculate that if he wanted to build a 5 billion kilowatt-hour power storage station, he would need at least 20 million tons of Thor's modified batteries.

The quoted price of Thor's modified batteries is 50,000 Chinese yuan per ton, which means that the total cost is about 1 trillion Chinese yuan. Including other supporting facilities, the total cost is no less than 1.5 trillion Chinese yuan.

Of course, Huang Haojie has promised that if they place a large order, the price can be given to them 40,000 yuan per ton after one year, and the price can be reduced to 30,000 yuan per ton after three years.

Of course, such a huge order cannot be decided by Du Lidao alone, and Dongtang Power Grid is not a private enterprise.

Even the Assets Committee does not have the authority to approve an order of this size, and requires personal approval from the Cabinet and the Grand Elder.
