There are three main costs for sand reclamation.

The first is the labor cost. The main time-consuming part is building the enclosure.

The second is the material cost. The most expensive one is geotextile, and others include wooden piles and wire.

The third is the cost of machinery, including the cost of these dredgers, kayaks, kayaks, and mud pipes.

Ling Ling has finally concluded that the average cost of one acre of land created in this way in the hinterland of Panshan Port is 60,000 yuan.

However, when sea sand is used for filling, the soil has high water content, relatively large pores, high compressibility, and poor bearing capacity.

Therefore, in practice, after dredging and sand blowing are completed to fill the land, natural settlement, secondary preparation, drying and precipitation, sand and gravel backfilling, rolling and compaction and other treatments must be carried out so that the land created by sand blowing can be turned into construction land.

Only after the general bearing capacity requirements are met can roads, buildings and factories can be built on top.

Based on this calculation, the cost of each acre of land would be 100,000.

100,000 acres of construction land is actually very cheap. It does not occupy farmland, does not require land acquisition procedures, and does not require various compensation fees for land occupation.

Also, the newly created land is just a blank piece of paper, and you can plan it however you want. This is also the reason why China's coastal areas have asked for land from the sea after entering the 21st century.

After the land is formed by blowing and filling, stone and gravel will be continuously filled and the strong compaction process will be used to form construction land on the port site as soon as possible.

The same is true for industrial park construction land.

Cement and gravel are needed to build the dam, and these building materials are also needed to build the road to the port and strengthen the foundation of the port site.

Donghua has built a cement plant and commercial concrete mixing station in Panshan, which can produce and process corresponding building materials.

But the stone is a bit troublesome.

Because there are no mountains near Panshan, it is not practical to dig mountains and quarry.

At present, there is no trace of the winding railway to Hong Kong. If we rely on roads to transport building materials over long distances, the cost will be ridiculously high.

Another way to obtain building materials and aggregates is to transport them by sea.

The so-called building materials aggregates are mainly gravel, pebbles, waste residue, sand, and fly ash. If used for land construction, all kinds of construction waste, house demolition ruins, and slag from steel plants can be used.

The most commonly used one is mountain skin stone, which is generally the stripped rock and soil during mining.

This kind of mountain skin stone is available in major mines. In order not to affect the mining, it is necessary to select spoil points over long distances to transport the mountain skin stone.

It would be better if there are road construction, port construction and other construction projects nearby. Not only do you not have to abandon them, but you can also sell them for a few pocket money.

The cost of mountain leather stone is mainly the transportation cost.

It doesn’t cost much to transport a large amount of mountain leather stone by sea. The freight from Western Australia to Panshan Port is about 15 yuan per ton.

However, Panshan Port's current wharf at the mouth of the Liaohe River can only handle 3,000-ton cargo ships, so it is not cost-effective to use small boats to transport pebbles across countries.

After much deliberation, Chen Lidong chose to use the golden finger - the system melting pot.

...

That afternoon, Chen Lidong came to Donghua's newly built thermal power plant in Panshan.

This thermal power plant has installed three sets of 300MW gas-steam combined cycle generating units. Each unit has four main components: gas turbine, waste heat boiler, steam turbine and generator.

General Manager Ding Dexin led Chen Lidong to visit this power plant that had been built but not yet put into operation.

After returning to the office, Ding Dexin said: "We have reached an agreement with Liaohe Oilfield Shallow Sea Oil and Gas Company for a daily gas supply of 800,000 cubic meters.

They have increased their investment and equipment since last year, and their daily output has reached 1 million cubic meters, which is basically eaten by us.

Our power plant consumes 0.17-0.34 cubic meters of electricity per kilowatt hour. If we maintain an output of 100 megawatts, it may operate at a high level. Each cubic meter of natural gas can only generate about 3 kilowatt hours of electricity, and 800,000 cubic meters of natural gas can barely maintain operation."

Chen Lidong asked: "Are the two storage tanks full?"

Ding Dexin said: "It's too late. One is empty, and the other stores 80,000 cubic meters of liquefied gas, which should be enough for two months."

The storage tanks they were talking about were two liquefied natural gas storage tanks with a capacity of 150,000 cubic meters purchased by Far East Trading, each equivalent to RMB 226.8 million. The labor cost for on-site welding alone cost RMB 150,000.

In addition to the ancillary facilities, this gas storage station cost a total of 760 million yuan. There is really nothing to spend the money on.

You know, this power plant only cost 1.188 billion.

Ding Dexin didn't know that the power plant equipment and gas storage station facilities were all flushed out of the system.

The volume of liquefied natural gas is only 1/600 of its gaseous state. Half a tank of liquefied natural gas can be used for two months, and two full storage tanks can survive a four-month gas shortage.

Chen Lidong continued to ask: "What is the price negotiated with them?"

Ding Dexin said: "One thirty-six cents. In theory, it can be reduced to one dollar and two, but considering that they have new equipment and funds are really tight, I will not force them anymore."

Chen Lidong nodded and said: "The key is that the oil and gas mining conditions here are poor. After we finish building the electrolytic aluminum plant, the electricity consumption will increase several times, and this little gas will definitely not be enough."

Ding Dexin also said with a somewhat gloomy face: "It is said that there are oil and gas resources in the sea, but when they explore and dig wells to find them, it will probably take not ten years but eight years."

Chen Lidong laughed and said, "How about we get a pipeline from the Far East?"

Ding Dexin was stunned: "Is it possible?"

Chen Lidong said: "Of course it is possible. Although you joined Donghua Wan, you should know that we have business in the Far East.

We have just taken over one of the largest oil and gas fields in Yakutia and are preparing to transport the oil and natural gas to Khabarovsk for processing and smelting.

My idea is to bring oil and natural gas here through long-distance pipelines and build a refining base in the country.

Do you know? The price of natural gas in the Far East is 13 knives per thousand cubic meters, which is equivalent to less than 12 cents per cubic meter in RMB."

Ding Dexin opened his mouth wide and gasped as he looked at the boss. He was not surprised by the price of oil and gas, but was surprised by the energy of this boss.

He graduated with a bachelor's degree in power machinery. His previous workplace was in the Shengli Oilfield in Shandong Province, and he knew a little about the oil and gas resources and production conditions in the Far East.

He has been busy building this thermal power plant for the past two years. It was basically completed a year ago and entered the commissioning stage, so he has not had much contact with people within the group. However, he knows from the group's internal documents and the Internet that Donghua is a multinational enterprise.

It even looks like a trust.

Shandong Province is a coastal province. Because it is close to the Sun Country and the Bangzi Country, the pace of reform and opening up is faster than that of its brother provinces. Therefore, Ding Dexin is one of the earliest people to "open their eyes to the world."

But since entering Donghua, my understanding has been constantly refreshed.

When he was introduced to Donghua by Shen Xing, he originally wanted to find a position in petroleum machinery.

Unexpectedly, after Luo Hao saw his academic qualifications and experience, he was sent to Panshan to take charge of the power plant work.

In this era, building gas-fired power plants is a bit ahead of its time. The cost of domestic gas-fired power generation in China is much higher than that of coal-fired power, with the cost per kilowatt-hour being at least a dime more.

Therefore, Ding Dexin once suggested that thermal power plants should use coal as fuel. His original suggestion was rejected by the young chairman in front of him.

Only then did Ding Dexin understand that Chen Lidong insisted on building a gas-fired power plant because he wanted to send natural gas from the Far East through pipelines.

Chen Lidong continued: "One cent and two cents is the ex-factory price, and transportation costs are not included. Referring to the price of shipping to Europe via Wuxiong, the natural gas freight is about $28 per thousand kilometers per thousand square meters.

It’s about 1,400 kilometers from Khabarovsk to Panshan. If you calculate it this way, you need to add 35 cents to the freight.

In other words, the price of transporting natural gas from Khabarovsk to Panshan is 0.47 yuan, which is only equivalent to 30% of the local natural gas. How about that?"

Ding De was convinced, what else could he say, two words: a good deal!

The power plant started construction at Chen Lidong's urging, and continuously transported electricity to nearby substations, including a thick cable that was transported to the southeast and into the sea.

Donghua Thermal Power Plant is built in the eastern part of Panshan Port Authority. It is isolated and has no neighbors. Further to the southeast and into the sea, there are only a few ships blowing sand to create land.

Now the four dredgers are working on mechanical servants. The two ships merged into one place, and then the mechanical servants summoned the space-time communication beacon, and then activated the system furnace clone.

Next, the furnace opened its huge mouth and spit out rocks the size of watermelons.

These stones sank to the bottom of the water, then scattered around, and then piled higher and higher, gradually emerging from the water. The place where the stones accumulated will be the roadbed of the road leading to the island.

It's so easy to turn on the furnace and build roads in the shallow sea.

If you use the system furnace to brush stones, you will have to pay 100 kilowatt hours of electricity per ton.

How to calculate electricity bills is a very complicated issue.

The electricity bill generally referred to in China is the cost incurred by the electricity consumed by users through the power grid within a certain period of time. The general electricity bill is about 5 cents per kilowatt hour.

However, the calculation of specific electricity bills is very complicated.

First of all, we must consider the type of power generation, thermal power, hydropower, nuclear power, wind power, photovoltaic. The cost of each power generation method is different.

Thermal power is also divided into different categories such as coal, oil, gas, etc. Fluctuations in fuel prices will also cause fluctuations in electricity prices.

This raises the issue of designing power generation costs. Most of the electricity generated by Huaxia power plants is priced on the national grid. Generally, the average annual method is used, which mainly considers several indicators such as power plant investment costs, service life, annual fuel consumption, operation and maintenance costs, and power generation efficiency.

Taking coal-fired power plants as an example, if labor costs, daily maintenance and other expenses are excluded, investment depreciation costs account for approximately 70% of power generation costs, and fuel costs account for 30%.

The equipment of the thermal power plant built by Donghua in Panshan is purchased from outside. The so-called outside procurement means that it is redeemed from the system. The cost is first ignored.

Chen Lidong went to the power plant to investigate. On the one hand, he was urging the start of power generation to ensure the reclamation project in the sea.

On the other hand, I want to calculate the cost. If the cost of generating electricity at home can be reduced, it will also comfort my soul.

However, after doing the calculations with Ding Dexin, I realized that generating 3 kilowatt hours of electricity consumes one gas. Without considering the depreciation of the power plant, the cost of one kilowatt hour of electricity is only 45 cents. Compared with purchasing electricity from the grid, it only costs less in handling fees and basic electricity charges. It’s really nothing.

Earn cheaply.

Calculating this, the cost of refining stone from the furnace is about 45 yuan per ton.

When the furnace is turned on, what comes out is materials, which are also RMB.

If the firepower is fully turned on, 100,000 kilowatt-hours of electricity per hour will cost 45,000 yuan, but 1.08 million yuan will be lost in one day. If a stone is thrown into the water, it is equivalent to throwing it away.

However, the speed of filling roadbed is also really fast. It can output 1,000 tons of stone in one hour, which is 24,000 tons in one day, which is equivalent to the transportation volume of a heavy-duty extended train.

The stones in the sea are growing at a speed visible to the naked eye, and the two dredgers need to be continuously moved under the tugboat.
