Chapter 104 Energy Storage (Medium Cup! More updates)

After a while, Li Zixuan came running over and said, "Boss, Manager Han from Jianfang Hydropower Construction Company has arrived at the company headquarters."

"We'll be back soon." Jiang Miao turned to look at his brother-in-law and Zhang Zhixing: "Sorry, I have some official business to attend to, so I'll leave you now. Brother-in-law, you stay with Manager Zhang. If there's anything you can't decide, call me."

"Mr. Jiang, you are too polite. Please go on with your work." Zhang Zhixing smiled and waved his hand.

My brother-in-law also nodded: "A Miao, you go ahead and leave this to me."

Ke Yong had already run to drive the car, and when Jiang Miao walked out of the farm gate, the pickup truck had already appeared on the roadside at the entrance.

The concrete ground beside the road was scorching hot from the sun. The wind blew past, bringing a gust of hot air, and everyone hurried into the car.

In less than five minutes, Jiang Miao and his team's pickup truck returned to the headquarters gate.

Inside 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. Li Xiaoxing, who was receiving them, quickly stood up and said, "Boss, this is Han Zhengdong, the manager of Jianfang Company."

Li Xiaoxing is Jiang Haibo's assistant and the person in charge of the company's daily reception of external guests. He turned around and introduced Jiang Miao to Han Zhengdong with a smile:

"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 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. He might be often out on business in the field, and his weather-beaten face made him look old.

As soon as he sat down, Jiang Miao didn't waste time and went straight to the point: "Manager Han, I won't exchange pleasantries. I am satisfied with your company's offer, but whether it can be successful still needs to be inspected on the spot, and it also needs to be approved by the relevant departments."

After hearing Jiang Miao's words, Han Zhengdong had never met such a frank and direct client, but he felt relieved. This kind of client was easier to get along with, unlike the previous clients who were a lot of trouble.

Then he thought for a moment, then said with a smile: "Boss Jiang, in fact, you can completely entrust this kind of hydropower project to our company. As for the full process approval of the project, our company has been working in this industry for more than ten years, and at least it still has a little face in various places in the south."

"Oh? Does your company have connections? How much is the agency fee?" Jiang Miao doesn't believe in good things that fall from the sky.

Han Zhengdong stroked the stubble on his chin and said, "If it is a small pumped-storage reservoir, the agency fee will be 100 million yuan, all inclusive. Of course, the construction cost will be calculated separately."

He added one last sentence.

Jiang Miao didn't think the fee was excessive. After all, the other party had run around a lot, so even if he made a little profit from the one million, it was what he deserved.

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 approved by just one department, but needs to go through many departments.

Moreover, it not only requires approval from the relevant local departments in Shanmei, but also involves many relevant departments at the higher level.

The current influence of Hailufeng Company can get the green light from relevant local departments, but it will not work at higher levels.

For Jiang Miao, time is the most precious thing. If spending one million can speed up the project approval, he will naturally not be stingy with this money. Then he nodded:
"Okay, without further ado, let's go straight to the scene!"

Although he felt that Jiang Miao was a little anxious, Han Zhengdong still chose to obey Party A's idea. He then smiled and replied, "I have no problem. President Jiang has already paid for the preliminary exploration of the project. We have also brought exploration equipment and engineers. The entire preliminary exploration work will take about a month."

There is still an hour and a half before noon, and Jiang Miao plans to strike while the iron is hot and deal with things as soon as possible so that he can go back to his scientific research.

As for Jiang Haibo, he went on a business trip to southern Jiangxi these days.

Three pickup trucks filed out of the parking lot at the company's headquarters.

Passing by the residential area of ​​Nanhu Village.

Then we turned south and reached the coastal breakwater. We drove east along the cement road on the breakwater for five or six hundred meters, and then entered a gravel road. We continued driving east for about two kilometers and stopped.

But we haven't arrived yet. We stopped because the road ahead is impassable for cars, so we have to get out and walk. Fortunately, we are not far away.

After walking along the path at the foot of the mountain along the coast for more than ten minutes, we finally arrived at a very obvious valley.

The valley faces the beach on the south side and is shaped like a trumpet, 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 valley mainly for the construction of an energy-storage reservoir.

The name of this mountain is Zhuzaishan.

Zhuzai Mountain and Yandun Mountain are two parallel small mountain ranges, both running east-west. The south side of Zhuzai Mountain faces the sea, and there are not many orchards and cultivated land around it, only large tracts of wild bamboo forests and Masson pine forests.

The contracted mountain land is right on the coast, with an area of ​​more than 6000 acres. The valley is about 700 to 900 meters away from the coast, and the altitude of the valley is about 70 to 120 meters.

It is only necessary to build a dam at the gap in the valley to construct a pumped storage reservoir, and the Zhuzaishan Reservoir directly uses seawater as water storage.

After all, there are no farmlands or orchards around, so we can directly pump seawater.

The reason for investing in the construction of this pumped-storage reservoir is to store electricity generated by solar panels.

The solar panels currently being installed at the Shiomachi farm, once fully installed, will cover an area of ​​350 acres. The scale of power generation generated by so many solar panels on a sunny day is enormous, reaching 12 to 14 kWh per day.

This power generation scale is very large for the current Hailufeng Company. At least the company's current industries cannot consume so much electricity.

What's more, Hailufeng Company's other industries also have large areas of vacant land. A rough calculation based on solar panels shows that the usable area is as much as thousands of acres.

This includes 150 acres of high-standard smart greenhouse roofs, 200 acres of indoor farm roofs, 120 acres of experimental area roofs, and the indoor farms for the feed factory, fish ball factory and Egyptian fish together cover about 300 acres.

Including the new office building and Dongtian real estate project, there are also 300 acres of usable area.

The supporting facilities area of ​​the Yandunshan durian plantation also has 200 acres of usable area.

All these add up to 1270 acres.

If all solar panels are laid, nearly 55 kilowatt-hours of electricity can be generated per day.

However, there is a big problem with solar panel power generation, which is the inability to provide stable power supply. Especially for factories, this unstable power generation is a fatal flaw.

Photovoltaics is known as junk electricity, and it is not just a name.

Moreover, the approval process for solar power generation projects to be online is very strict, and the price of electricity is not high.

After all, in the past decade, too many photovoltaic and wind power projects have been launched in China, and these two so-called "green and environmentally friendly energy" are called junk power in the industry because of their unstable power generation.

The power grid needs a stable power source, rather than the seemingly huge but wildly fluctuating photovoltaic and wind power. This has led to the power grid gradually tightening the grid connection approval for wind and photovoltaic projects, and encouraging small and medium-sized photovoltaic and wind power projects to fend for themselves.

Therefore, the current proportion of wind power and photovoltaic power abandonment in the country is very large, because it is becoming increasingly difficult to access the grid.

Jiang Miao had previously planned to increase the company's energy self-sufficiency rate, so he planned to invest in laying a batch of solar panels, but when he came to his senses, he realized that he had overlooked a problem.

It is the instability of solar power generation.

After much thought, his solution was to build a pumped-storage reservoir and generate his own electricity for his own use.

Of course, before planning to invest in the construction of a pumped-storage reservoir, Jiang Miao conducted a survey of the area around Magong Town and took the opportunity to travel around the mountains and rivers with Shuya for a few days.

While traveling around the mountains and rivers, he found that Zhuzaishan, which was close to the sea, was a good location.

The volume of this valley is not small. If the height of the dam is about 50 meters, that narrow valley can store 600 million cubic meters of seawater under extreme conditions.

If 600 million cubic meters of seawater are released at an altitude of 70 meters, theoretically 77 kilowatt-hours of electricity can be generated.

Therefore, if this reservoir is built, it will not only be a huge battery for the electricity generated by Hailufeng Company, but also have a large surplus of energy storage capacity. This storage capacity is enough for the short term, but it is hard to say what will happen in the future.

After all, the so-called surplus storage capacity is calculated based on the current industrial area of ​​Hailufeng Company. As the company's local industries continue to expand in the future, the storage capacity of this energy-storage reservoir may not be sufficient.

In fact, this kind of coastal mountain range has great potential for developing seawater pumped storage reservoirs.

After all, at the seaside, there is no problem of regulating the amount of water. You can pump water whenever you want and release water whenever you want.

If the reservoir is next to a river or lake in an inland area, it is impossible to pump and release water at will, because this is not only related to power generation issues, but also agricultural irrigation, inland shipping, flood control and drought relief, etc.

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 attachment, infiltration and leakage, and stable operation.

Jiang Miao can solve some of these problems.

As for the problem of equipment corrosion, this can only be solved by the equipment itself.

However, microbial attachment 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 checked the location of the Zhuzaishan Sea Reservoir through the identification panel and found that the rock layers of the surrounding mountains are very thick and there are not many underground cracks that can be penetrated.

Moreover, this reservoir is right next to the sea, so there is no possibility of sea water flooding farmland, orchards, or polluting freshwater rivers.

As for stable operation, this problem actually depends on how it is used. As long as the plans of pumping energy storage and releasing water for power generation are arranged reasonably, this problem can be avoided.

...

The group climbed to the halfway point of the mountain at the entrance of the valley.

The sea breeze brought a heat wave mixed with a fishy smell.

The roar of waves hitting the rocks lingers in my ears.

Jiang Miao, who has eight-pack abs, stood on a big rock halfway up the mountain without blushing or breathing hard.

Han Zhengdong was panting slightly at the side. He smiled bitterly and said, "Huhu... Mr. Jiang is in great health. When I was in the southwest, I often climbed mountains and waded through water, but now my health is not as good as before."

"Manager Han, what do you think of this valley?"

"Let me take a look." Han Zhengdong picked up the telescope and carefully observed the boundaries, length, width and height of the valley.

After observing for more than ten minutes, he took out a small notebook, gestured a few times with his fingers, and wrote down a series of data in the notebook.

After Han Zhengdong finished his calculations, he turned to look at Jiang Miao and said, "If we build a 50-meter-high dam on the small slope in front, it will not only minimize the amount of construction work, but also increase the height difference to about 70 meters. The remaining valley reservoir capacity limit should be around 620 million cubic meters."

Looking at the sketch handed over by the other party, Jiang Miao nodded calmly while reading it.

It is obvious that Han Zhengdong is indeed a professional. Even without the help of professional tools, he can roughly calculate the approximate storage capacity, and the location he chooses 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 notebook to him and asked, "Manager Han, if we follow your plan, how much will the reservoir cost?"

"I can only give Mr. Jiang a rough reference price."

"Manager Han, please feel free to speak up. This will also help me have some peace of mind."

"Based on the maximum storage capacity of 620 million cubic meters and a water outlet drop of 70 meters, this reservoir can be equipped with a 250-megawatt hydroelectric unit. The overall cost of a pumped-storage reservoir is currently about 500 to 600 million yuan per megawatt. Mr. Jiang can figure it out with a simple calculation."

Jiang Miao made a quick estimate in his mind and came up with a number.

The overall construction cost is around 12.5 to 15 billion yuan.

Jiang Miao already had an idea of ​​the price, and it was within his psychological expectations.

"Manager Han, how long will it take to complete this project?"

Han Zhengdong smiled and explained: "It depends on the situation. If it is a small pumped storage reservoir project with official investment, 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 formalities, planning and preparation period, main project construction period, project completion period, and completion acceptance period."

"Since 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 small pumped storage power station built by our company before. It took 48 months from the start of the main project to the full commissioning of the power station, and only 18 months to install and commission the first unit."

Jiang Miao calculated in his mind: "In other words, the fastest time is about 5 years."

Han Zhengdong nodded. "It can be even faster, because the mountains here are relatively compact. 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 be fully operational, and the cost can be reduced."

Now Jiang Miao felt more confident.

As for the issue of money, with Hailufeng Company's current rate of making money, there is no need to worry about the construction cost of more than one billion yuan.

What's more, this project will take at least 40 months, and the project payment will definitely not be paid in one lump sum. If it is paid in installments, there will not be much pressure on Hailufeng Company's capital turnover.

Whether the investment can be recovered depends on how it is used.

If we calculate based on 10 billion kWh of electricity generated each year and 0.3 yuan per kWh, we can earn about 3 million yuan per year, and the investment can be recovered in 4 to 5 years.

But Jiang Miao doesn't intend to use the 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 steel structures to turn it into a large indoor farm. Solar panels should be laid on top to generate electricity, and the sea water inside could be used to arrange large cages.

Due to the protection of the steel structure dome, the water temperature inside the reservoir will become relatively low, and the electricity generated can be used for refrigeration to create an artificial cold water area in the reservoir.

Therefore, salmon can be farmed in this special environment.

The farming density of salmon is 5 to 25 kilograms per cubic meter.

The reservoir's maximum storage capacity is 620 million cubic meters. Considering the needs of power generation and pumped storage, a certain amount of space must be left. Therefore, the storage capacity available for salmon farming is about 200 million cubic meters, which means farming 1 to 5 tons of salmon.

The current landed price of Norwegian salmon is RMB 11 to 13 per ton.

Taking into account the impact of localization on the market and the huge domestic consumer market, if Hailufeng Company produces salmon on a large scale, the wholesale price per ton can be maintained at at least 8 to 9 yuan.

The normal salmon breeding cycle is about 3 years.

This means that Zhuzaishanhai Reservoir can generate revenue of 8 million to 9 million yuan every year from selling salmon.

With clear market expectations, huge capital, and technical support, this type of project is a sure-win investment.

And Hailufeng Company just meets these three conditions.

In fact, a Norwegian salmon farming company has planned to invest in the construction of a large-scale onshore indoor farm in China, which seems to be located in Zhejiang Province. By farming salmon locally, it is convenient to directly supply the Yangtze River Delta region, especially Shanghai and Hangzhou where there are a large number of Japanese people. These are the key markets targeted by this company.

If Hailufeng Company produces salmon on a large scale in the future, it will definitely have to compete with this Norwegian salmon company.

However, the core market of Hailufeng Company is definitely the Pearl River Delta region.

In order to reduce aquaculture costs, the pumping pipes cannot directly pump high-temperature seawater from the surface of the sea, but must pump low-temperature seawater from the bottom of the sea, which can reduce the cost of cooling the seawater.

Although this reservoir is a hydroelectric power station with a large solar panel on it, we should still try to save electricity as much as possible.

　Sorry! The leader will update it tomorrow.
