the other side.

The boss of Dongtang Power Grid, who was originally scheduled to visit on January 1, changed the time to January 3 due to an emergency.

Raytheon Group also has no objection, because their president Fang Shengjie is currently in a lawsuit at Mi Li's house.

Huang Haojie can only entertain the boss of Dongtang Power Grid in person.

Huang Haojie took Du Lidao, the boss of Dongtang Power Grid, to Jieshi Bay, Shanmeilu City, where there is the first wind power station that Haifeng Wind Power Company has just completed.

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

These large wind turbines with a generating power of up to 1500 kWh can generate 5 to 6 kWh in one hour.

Du Lidao looked at the wind turbines running at high speed, and asked the wind power experts who followed him:
"Zhang Gong, how efficient are these wind power plants?"

It may be the reason why he often works outdoors. This Zhang Gong has rough and dark skin. He said very excitedly and excitedly:

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

After listening to Mr. Zhang's explanation, Du Lidao, as the boss of Dongtang Power Grid, is still clear about these power generation methods.

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

However, considering the cost of horizontal wind turbines, vertical wind turbines have made a comeback. The cost per kilowatt of horizontal wind turbines is about 3000-4000 Chinese yuan; the cost of vertical wind turbines is about 2000 Chinese yuan per kilowatt.

After thinking for a while, Du Lidao asked Huang Junjie who was beside him:
"Mr. Huang, what is the cost or selling price of your fan?"

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

"It costs 5000 Wah per kilowatt, and a large wind turbine with a power of 1500 kWh costs 750 million Wah. A wind turbine can generate about 1000 million kwh a year, and the cost can be paid back in about three years." Fang Ping on the side quickly replied road.

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

"Three years to pay back? Is it in the rich area?"

Fang Ping quickly shook his head and explained:

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

"In that case, your starting wind speed should be very low." An expert is an expert, Zhang Gong asked the main points straight away.

Fang Ping nodded: "That's right, our Haifeng 2 wind turbine starts with a wind speed of 1.2 meters per second."

Du Lidao on the side calculated that if a wind turbine with a power of 1500 kWh could generate 1000 million kWh of wind power a year, it would be very promising.

"Boss Huang! Can I check your generator system?"

Huang Haojie nodded: "Yes!"

"Mr. Zhang, take a few people to have a look!"

Hearing Du Liguo's words, Zhang Gong immediately became excited. After all, for a wind power expert, he can personally experience this cross-generational product, just like a gourmet encountering a rare delicacy.

He hurriedly took a lot of instruments and four or five staff members of the State Grid, and headed for the nearest wind turbine.

In order to prevent them from ignoring 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, such as on-site wind speed, blade surface area, volume, weight, generator output power and so on.

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

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

Du Lidao looked at the report in his hand, and couldn't help squinting. A 1500-kilowatt-hour wind turbine costs 750 million yuan, including supporting facilities. Calculated at 900 Huayuan, it can really pay back in almost three years.

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

"Boss Huang, your wind power technology is beyond doubt."

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

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

"No problem! Please follow me!"

Huang Haojie led Du Lidao and his party into the storage power station of the Stone Bay No. [-] Power Station.

Rows of 20-meter-high reinforced concrete bungalows appeared in front of everyone.

"Mr. Du, this is the storage station area of ​​the No. [-] power station. Each power storage warehouse has a thousand tons of Thor modified batteries. There are a total of [-] power storage warehouses. Of course, due to the production problem of Thor modified batteries, temporarily We only have three storage bins."

Huang Haojie introduced as he walked.

"How much electricity can be stored in a power storage bin or a thousand tons of Thor's modified batteries?" Du Lidao asked quickly.

"A power storage bin can store 24 kilowatt-hours of electricity. Of course, the power of the power storage bin is only for the convenience of dispatching. Only a part of the power generation of the power station is stored here."

Du Lidao nodded. Of course he knew that the function of the storage power station was not to store electricity, but to adjust the unevenness of time and space of electric energy.

Last year (2016), Dongtang's annual power generation was 6.14 trillion kwh, with an average daily power generation of 170 billion kwh.

It is only necessary to build a storage power station with a storage capacity of about 50 billion kWh.

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

Does this seem like a superfluous feeling?

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

Dongtang generates 170 billion kilowatt-hours a day, which means that it needs an installed capacity of 8 million kilowatts.

In fact, Dongtang's national power generation installed capacity in 2016 was 15 billion kilowatts.

The reason for this situation is that there are more than 3 million kilowatts of wind power and photovoltaic power. These unstable power sources must be matched with thermal power plants of similar capacity to adjust.

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

It is the instability of these wind power and photovoltaics that has led to a utilization rate of only about half of the country's total installed capacity of 15 billion kilowatts.

If the use of storage power stations is promoted, the domestic installed capacity of power generation can be reduced to about 10 billion kilowatts, which can meet the normal needs of the country.

After visiting for more than three hours.

Du Lidao, who was still thinking about it, began to calculate that if he wanted to build a 50 billion kWh storage power station, he would need at least 2000 million tons of Raytheon modified batteries.

The quotation of Raytheon's modified battery is 5 Wah Yuan per ton, which means that it will cost about 1 trillion Wah Yuan in total. Adding other supporting facilities, the total cost will not be less than 1.5 trillion Wah Yuan.

Of course, Huang Haojie has promised that if they place a large order, the price will be 4 yuan per ton after one year, and the price will drop to 3 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 right to approve an order of this scale, and needs to be personally approved by the cabinet and the Great Elder.
