The other side.

The CEO of Dongtang Power Grid, who was originally scheduled to come to visit on January 3, changed the time to January 10 due to emergencies.

Raytheon Group also has no opinion, because their president Fang Shengjie is fighting a lawsuit at Mi Lijia at this time.

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

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

Fifty huge vertical wind turbines are running rapidly.

These large wind turbines with a power generation of up to 1500 kWh can generate 5~60,000 kWh of electricity in one hour.

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

"Zhang Gong, how efficient are these wind powers?"

Probably because he often works outdoors, this Zhang Gong has rough and dark skin, and he is very excited and excited to say:

"Mr. Du, it's really amazing, I just calculated the comprehensive efficiency of their fans, and it has reached 48~50%, which is a miracle."

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

He knows that the strongest vertical wind turbine on the market currently has a comprehensive efficiency of about 20%, and the horizontal wind turbine is about 50% in theory, but in fact it is about 30%.

However, considering the cost of horizontal wind turbines, vertical wind turbines have pulled back a game, and the cost of horizontal wind turbine door kilowatts is about 3000~4000 yuan; Vertical wind turbines cost about 2,000 yuan per kilowatt.

After thinking about it for a while, Du Lidao asked Huang Haojie on the side:

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

Perhaps considering that it was not appropriate to ask the cost directly, Du Lidao asked the price instead.

"At 5,000 yuan per kilowatt, a large wind turbine with a power of 1,500 kilowatt-hours costs 7.5 million yuan, and a wind turbine can generate about 10 million kilowatt-hours of electricity a year, which can be repaid in about three years." Fang Ping on the side hurriedly replied.

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

"Three years to pay back? Is it in the Rich Zone?"

Fang Ping hurriedly shook his head and explained:

"No, it's in a more abundant area, if it's in an abundant area, it may not take about three years, if it's in an available area, it's about four or five years! This figure is calculated based on Shanmei Stone Bay, where wind energy is probably between abundant and available. ”

"In that case, your starting wind speed should be very low." An expert is an expert, and Zhang Gong asked the main point directly.

Fang Ping nodded: "That's right, our Haifeng Type 2 wind turbine has a starting wind speed of 1.2 meters per second. ”

Du Lidao on the side calculated that if a wind turbine with a power of 1,500 kilowatt-hours can really generate 10 million kilowatt-hours of wind a year, it is really promising.

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

Huang Haojie nodded: "Yes!" ”

"Zhang Gong, you take a few people to take a look!"

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

He hurriedly took a large number of instruments and four or five State Grid workers and headed for the nearest wind turbine.

In order to avoid the situation that they could not understand the wind turbine, Zhang Haifeng and other Haifeng wind power engineers also followed.

Zhang Gongzai carefully tested various data of the wind turbine, such as the wind speed on site, the surface area, volume, and weight of the blades, and the output power of the generator.

After testing for more than an hour, a data similar to that of Haifeng Wind Power was finally obtained.

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

Du Lidao looked at the report in his hand, and couldn't help squinting his eyes, a 1500 kWh wind turbine is 7.5 million yuan, plus supporting facilities, the total cost is about 9 million yuan, with the current wind power feed-in tariff of 0.3 yuan per kilowatt hour, it can really pay back in almost three years.

However, he was more interested in the Thor modified battery.

"Mr. Huang, there is no doubt about your wind power technology."

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

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

"No problem! Please follow me! ”

Huang Haojie took Du Lidao and his party into the storage power station of the No. 1 power station in Jieshiwan No. 1.

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

"Mr. Du, this is the storage station area of the No. 1 power station, each storage bin has a thousand tons of Raytheon modified batteries, a total of 30 storage bins, of course, due to the production of Raytheon modified batteries, for the time being, we are only equipped with 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 modified batteries?" Du Lidao hurriedly asked.

"A storage bin can store 240,000 kilowatt hours of electricity, of course, the power of the storage bin is just for the convenience of scheduling, and only part of the power generation of the power station is stored here."

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

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 storage power station with a storage capacity of about 5 billion kilowatt hours.

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

Doesn't that seem like a redundant move?

In fact, this can save a very large amount of electricity, as well as reduce a very large installed power generation capacity.

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

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

The main reason for this situation is that there are more than 300 million kilowatts of wind power and photovoltaic power, and these unstable power sources must be regulated by thermal power stations of similar capacity.

Otherwise, with wind power and photovoltaic power generation from time to time, sometimes large and sometimes small, one-third of the country's electricity consumption will be seriously affected.

It is the instability of wind power and photovoltaic power that has led 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 storage power stations is promoted, then the installed power generation capacity of the country can be reduced to about 1 billion kilowatts, which can meet the normal needs of the whole country.

After visiting for more than three hours.

Du Lidao, who was still unsatisfied, began to calculate that if he wanted to build a storage power station of 5 billion kilowatt hours, at least 20 million tons of Raytheon modified batteries would be needed.

The price of Raytheon modified battery is 50,000 Chinese yuan per ton, which means that a total of about 1 trillion Chinese yuan is needed, plus other supporting facilities, the total cost is not less than 1.5 trillion Chinese yuan.

Of course, Huang Haojie has promised that if they place a large order, the price can give them 40,000 yuan a ton after one year, and the price can drop to 30,000 tons 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.

For an order of this size, even the Assets Committee does not have the right to approve it, and it needs to be approved by the Cabinet and the Grand Elder in person.
