Chapter 104 Energy Storage (Medium Cup! More updates)
After a while, Li Zixuan trotted over: "Boss, Manager Han from Jianfang Hydropower Construction Company has arrived at the company headquarters."
"We'll go back right away." Jiang Miao turned to look at her brother-in-law and Zhang Zhixing: "Sorry, I have some official business to deal with, so I'll excuse you now. Brother-in-law, please stay with Manager Zhang. If there's anything you can't decide, give me a call. .”
"Mr. Jiang is too polite, please do your work first." Zhang Zhixing smiled and waved.
The brother-in-law also nodded: "Ah Miao, you go ahead and leave it to me."
Ke Yong had already run to drive. When Jiang Miao walked out of the farm gate, the pickup truck had already appeared on the roadside at the door.
The concrete floor beside the highway was scalding hot from the sun, and the wind blew by, bringing a blast of hot air. Everyone hurriedly got in the car.
In less than five minutes, the pickup truck of Jiang Miao and his team arrived at the entrance of the headquarters.
The reception room of the headquarters.
Han Zhengdong, the project manager of Jianfang Company, who was drinking tea, suddenly saw the door of the reception room being pushed open, and Li Xiaoxing, who was receiving them at the side, quickly stood up: "Boss, this is Manager Han Zhengdong of Jianfang Company."
Li Xiaoxing is Jiang Haibo's assistant and the person in charge of the company's daily reception of foreign guests. He smiled and turned around to introduce Jiang Miao to Han Zhengdong:
"Manager Han, this is our boss, Mr. Jiang Miao."
"Hello, Manager Han."
“It’s a great honor to meet Mr. Jiang.”
The two shook hands and took their seats.
Han Zhengdong's face looked like he was in his forties or fifties. In fact, Jiang Miao found out through the identification panel that he was only 39 years old. It may be that he often ran business in the field, and his weather-beaten face made him look old.
As soon as he sat down, Jiang Miao didn't hesitate and got straight to the point: "Manager Han, I won't make small talk. I am satisfied with your company's quotation. However, whether the matter can be done or not, we need to conduct an on-site inspection and see the relevant information." Department approval.”
Hearing Jiang Miao's words, it was the first time for Han Zhengdong to meet such a frank and direct Party A, but he also breathed a sigh of relief. This kind of Party A was actually easier to get along with, unlike the troublesome customers before. Big pile.
Then he thought for a moment and said with a smile: "Mr. Jiang, in fact, you can completely entrust this kind of hydropower project to our company. Our company has been in this industry for more than ten years for the entire project approval process. At least there is still some respect in the south.”
"Oh? Does your company have connections? How much is the agency fee?" Jiang Miao doesn't believe in good things like pie-in-the-sky.
Han Zhengdong touched the stubble on his chin: "If it is a small pumped storage reservoir, the agency fee is 1 million yuan, and of course the construction cost is additional."
He added one last sentence.
Jiang Miao didn't think this fee was excessive. After all, he was running around, and even if he made a little profit, he still deserved it.
For companies that are not familiar with the hydropower construction industry, the approval process is the most troublesome thing. After all, it is not something that can be passed by one department, but needs to go through many departments.
And it not only requires approval from the relevant local departments in Shanmei, but also involves many relevant departments at a higher level.
The current influence of Hailufeng Company can give the relevant local departments the green light, but it does not work for higher levels.
For Jiang Miao, time is the most precious thing. If he spends one million, the project approval can be passed quickly. Naturally, he will not be stingy with the money, and then he nodded:
"Okay, without further ado, let's go directly to the scene!"
Although he felt that Jiang Miao was a little urgent, Han Zhengdong still chose to comply with Party A's ideas, and then he replied with a smile: "There is no problem on my side. Mr. Jiang has paid for the preliminary exploration costs of the project, and we have also brought exploration equipment and Engineer, the entire preliminary exploration work will take about a month.”
There was still an hour and a half until noon, and Jiang Miao also planned to strike while the iron was hot and deal with the matter as soon as possible so that he could return to scientific research.
As for Jiang Haibo, he has been on a business trip to southern Jiangxi these days.
Three pickup trucks filed out of the parking lot of the company's headquarters.
Passing by the residential area of Nanhu Village.
Then turn south and reach the coastal breakwater. Drive eastward for five or six hundred meters along the cement road on the breakwater, then enter a section of gravel road. Continue eastward for about two kilometers and stop.
But we haven’t arrived yet. We stopped because the road ahead was impassable for cars, so we had to get out of the car and walk. Fortunately, we were not far away.
After walking on the path at the foot of the coast for more than ten minutes, we finally reached a very obvious valley.
The beach facing south in the valley is distributed in a trumpet shape, with hills hundreds of meters high on both sides. There is also a small stream in the middle of the valley, but the water flow is very small.
Hailufeng Company contracted this mountainous area mainly to build energy storage reservoirs.
The name of this mountainous area is Zhuzi Mountain.
Zhuzai Mountain and Yandun Mountain are two parallel small mountain ranges, both running east-west. The south side of Zhuzai Mountain faces the seaside. There are not many orchards and cultivated land around it, only large wild bamboo forests and masson pine forests.
The contracted mountainous land is right on the coast, covering an area of more than 6,000 acres. The distance between the mountain col and the coast is about 700 to 900 meters, and the altitude of the mountain col is about 70 to 120 meters.
You only need to build a dam at the gap in the mountain col to build an energy storage reservoir, and the Zhuzaishan Reservoir directly uses seawater as water storage.
After all, there are no farmlands or orchards around, so seawater can be pumped directly.
The reason why we need to invest in the construction of this pumped storage reservoir is to store the electricity generated by solar panels.
If all the solar panels currently being installed at the Shiomachi Farm are completed, there will be as many as 350 acres of solar panels. The power generation scale of these many solar panels on a sunny day is very large, and can reach 120,000 to 140,000 degrees per day.
This power generation scale is very large for the current Hailufeng Company, at least the company's current industries cannot consume this much electricity.
What's more, Hailufeng Company's other industries also have a lot of open space. It can also be roughly calculated based on solar panels, and the usable area is up to thousands of acres.
This includes 150 acres of high-standard smart greenhouse roofs, 200 acres of indoor breeding farm roofs, 120 acres of experimental area roofs, feed factory, fish ball factory and Egyptian fish indoor breeding farm totaling about 300 acres.
Coupled with the new office building and the Dongtian real estate project, there are also 300 acres of available area.
The supporting facilities area of Yandunshan Durian Plantation also has 200 acres of available area.
All these added up to 1,270 acres.
If all solar panels are installed, nearly 550,000 kilowatt hours of electricity can be generated a day.
However, there is a big problem with the power generation of solar panels, that is, the power supply cannot be stable. Especially for factories, this unstable power generation situation is simply a fatal shortcoming.
Photovoltaic is known as garbage electricity, but it is not in vain.
Moreover, the current grid approval for solar power generation projects is very strict, and the electricity sales price is not high.
After all, in the past ten years, too many photovoltaic and wind power projects have been launched in China. However, these two so-called "green energy sources" are called garbage power in the industry because their power generation is unstable.
The power grid needs a stable power supply, not the seemingly huge but violently fluctuating photovoltaic and wind power. This has led the power grid to gradually tighten the grid connection approval of wind power and photovoltaic projects, encouraging those small and medium-sized photovoltaic and wind power projects to make a living on their own.
Therefore, the current proportion of wind power and photovoltaic power curtailment in China is very large, because it is becoming more and more difficult to access the Internet.
Previously, Jiang Miao planned to invest in laying a batch of solar panels to increase the company's energy self-sufficiency, but when he came to his senses, he realized that he had overlooked an issue.
It’s the instability of solar power generation.
After much thought, his solution was to build his own pumped storage reservoir and generate electricity for his own use.
Of course, before planning to invest in the construction of a pumped storage reservoir, Jiang Miao conducted a survey around Magong Town and took a few days of sightseeing with Shuya.
While traveling around the mountains and rivers, he found that Zhuzai Mountain near the sea was a good location.
The volume of this mountain valley is not small. If the height of the dike is about 50 meters, that long and narrow valley can store 6 million cubic meters of seawater under extreme conditions.
All 6 million cubic meters of seawater are released at an altitude of 70 meters, which can theoretically generate 770,000 kWh of electricity.
Therefore, if this reservoir is built, it will not only be able to create a huge battery for the electricity generated by Hailufeng Company, but also have a large amount of spare energy storage capacity. This library capacity will be sufficient in a short period of time, but it is difficult to say in the future.
After all, the so-called surplus storage capacity is calculated based on the current industrial area of Hailufeng Company. In the future, as the company's local industry continues to expand, the storage capacity of this energy storage reservoir may not be enough.
In fact, this kind of coastal mountain range has great potential for developing seawater pumped storage reservoirs.
After all, at the beach, there is no problem of regulating the amount of water. You can pump water when you want, and release water when you want.
If the reservoir is next to rivers and lakes in inland areas, there is no way to pump and release water casually, because this is not only related to power generation issues, but also agricultural irrigation, inland navigation, flood control and drought relief and other issues.
This is why many articles introducing pumped storage reservoirs mention the problem of site selection.
Although seawater pumped storage technology has obvious advantages, there are also some technical challenges, such as equipment corrosion, microbial adhesion, penetration and leakage, and stable operation.
Jiang Miao can solve some of these problems.
The equipment corrosion problem can only be solved by equipment.
However, microbial adhesion can be removed regularly using physical means, so this is not a big problem.
There is no need to worry about seawater infiltration and leakage, because Jiang Miao has seen the location of the Zhuzishan Seawater Reservoir through the identification panel. The rock formations in the surrounding mountains are very thick, and there are not many underground gaps that can penetrate.
Moreover, this reservoir is right on the seaside, so there is no need for seawater to flood farmland, orchards, or pollute freshwater rivers.
As for stable operation, this problem actually depends on how it is used. As long as the plan for pumping water for energy storage and releasing water for power generation is properly arranged, this problem can be avoided.
…
The group of people climbed to the mountainside at the entrance of the valley.
The sea breeze brings a fishy heat wave.
The sound of waves crashing against the rocks filled my ears.
Jiang Miao, who has eight-pack abs and is neither blushing nor out of breath, is standing on a big rock halfway up the mountain.
On the side was Han Zhengdong, who was panting slightly. He said with a wry smile: "Huhu... Mr. Jiang is in really good health. When I was in the southwest, I often climbed mountains and waded in rivers, but now my health is not as good as before."
< br>
"Manager Han, what do you think of this valley?"
"Let me take a look." Han Zhengdong picked up the telescope and carefully observed the boundary, length, width and height of the valley.
After observing for more than ten minutes, he took out a small book, made a few gestures with his fingers, and wrote down a series of data in the small book.
After Han Zhengdong completed the calculation, he turned to look at Jiang Miao and said, "If you build a 50-meter-high embankment on the small slope in front, you can not only minimize the amount of construction work, but also increase the height to about 70 meters. , the remaining valley storage capacity limit should be about 6.2 million cubic meters.”
Looking at the sketch handed over by the other party, Jiang Miao nodded calmly while looking at it.
Obviously Han Zhengdong is indeed a professional. Even without the help of professional tools, he can roughly calculate the approximate storage capacity, and the selected location is also very suitable.
He continued: "Next, it depends on the geological conditions of the valley. If there are no major problems, a small pumped storage reservoir can indeed be built here."
Jiang Miao returned the small book to him, and then asked: "Manager Han, if you follow your planning plan, how much will the reservoir cost approximately?"
"I can only give Mr. Jiang a rough reference price."
"Manager Han said it's okay. This will give me some peace of mind."
"Based on the ultimate storage capacity of 6.2 million cubic meters and the outlet drop of 70 meters, this reservoir can install a 250-megawatt hydropower unit. The current overall cost of pumped storage reservoirs is about 5 to 6 million yuan per megawatt. Jiang finally knew it.”
Jiang Miao made a little calculation in her mind and came up with a figure.
The overall construction cost is about 1.25 to 1.5 billion yuan.
Jiang Miao already knew this price, and it was within his psychological expectations.
"Manager Han, how long will the progress of this project take?"
Han Zhengdong explained with a smile: "It depends on the situation. If it is a small pumped storage reservoir project invested by the government, it will take at least 5 to 8 years, because it needs to go through the pre-feasibility study stage, feasibility study stage, approval and other procedures. , preparation and preparation period, main project construction period, project completion period, and completion acceptance period. ”
"And you are a private enterprise. Some of the previous processes can be simplified and compressed. The only time that cannot be compressed is the construction period of the main project. The specific time depends on the complexity and scale of the project, but you can refer to a project our company built before. For a small pumped storage power station, it took 48 months from the start of the main project to the full commissioning of the power station, and the installation and commissioning of the first unit only took 18 months.”
Jiang Miao calculated in his mind: "In other words, the fastest is about 5 years."
Han Zhengdong nodded: "It can even be faster, because the mountain at this location is relatively dense. If the bedrock below is relatively stable and solid, the amount of work can be reduced by more than half. It is estimated that it will only take about 40 months to fully complete the project." When put into production, the cost can be reduced a bit.”
Now, Jiang Miao felt confident.
As for the money issue, with the current rate at which Hailufeng Company is making money, there is no need to worry about the cost of more than one billion.
What's more, this project will take at least 40 months, and the project payment is definitely not a one-time payment. In the case of installment payment, there will be little pressure on Hailufeng's capital turnover.
Whether the investment can be repaid depends on how it is utilized.
If we calculate it based on generating 1 billion kilowatt-hours of electricity per year, at 0.3 yuan per kilowatt-hour, we can earn approximately 300 million yuan per year, and we can pay back the capital in 4 to 5 years.
But Jiang Miao does not intend to use this reservoir in this way.
If it is simply used as a pumped storage reservoir, the land utilization rate and water resource utilization rate will be too low.
In Jiang Miao's vision, the entire reservoir should be wrapped with a steel structure and turned into a large indoor breeding farm. Solar panels should be laid above to generate electricity, and large cages can be placed in the seawater inside.
Due to the shielding of the steel structure dome, the water temperature in the reservoir will become relatively low. The electricity generated by power generation can be used for refrigeration and artificial cold water in the reservoir.
Therefore, salmon can be cultured in this special environment.
The breeding density of salmon is 5 to 25 kilograms per cubic meter.
The ultimate storage capacity of the reservoir is 6.2 million cubic meters. Taking into account the needs of power generation and pumped storage, a certain amount of space must be left. Therefore, the storage capacity that can be used for salmon farming is about 2 million cubic meters, which means farming 10,000 to 50,000 tons of salmon. .
The current CIF price of Norwegian salmon per ton is 110,000 to 130,000.
After considering the impact of localization on the market, but also taking into account the huge domestic consumer market, if Hailufeng Company mass-produces salmon on a large scale, the wholesale price per ton can be maintained at at least 80,000 to 90,000 yuan.
The normal salmon breeding cycle is about 3 years.
This means that Zhuzai Shanhai Reservoir can generate revenue of 800-900 million yuan every year from selling salmon.
With clear market expectations, huge capital, and technical support, this kind of project is a sure-profit investment.
Hailufeng Company has exactly these three conditions.
In fact, Norwegian salmon farming companies have already planned to invest in the construction of a large-scale land-based indoor breeding farm in China. The location seems to be in Zhejiang Province. By cultivating salmon on the spot, it is convenient to directly supply the Yangtze River Delta region, especially the magic city where Japanese people are concentrated. and Hangzhou are the key markets this company is targeting.
If Hailufeng Company produces salmon on a large scale in the future, it will definitely compete with this Norwegian salmon company.
However, Hailufeng's core market is definitely the Pearl River Delta region.
In order to reduce breeding costs, the water pumping pipeline cannot directly pump high-temperature seawater on the surface of the sea, but must pump low-temperature seawater on the seabed, which can reduce the cost of seawater cooling.
Although this reservoir is a hydropower station with a large solar panel on it, we still need to save as much electricity as possible.
sorry! The leader has added an update and will make it up tomorrow
