China store can net dispatch: China is experiencing throughout history dimensions the biggest store can invest and build cycle.
Released in August 2021 according to bureau of national energy resources " pump water harbour can be medium long-term development plans (2021-2035 year) " , to 2025, harbour of Chinese pump water can accumulative total installation amount should achieve 62GW above, achieve 120GW to 2030, up to by 2021, pump water harbour can install machine dimensions to be 39.8GW only. This means 9 years a growing space that has 3 times, compound year all increase rate is 13% .
But build dimensions general Yuan Chao actually hereat. This year first 7 months, already caught give an official but have not the pump water harbour of start working can the project amounts to 102 namely, 126.9GW of general assembly machine.
Change according to national hair appoint, bureau of national energy resources released in July 2021 " drive about accelerating new-style store the directive opinion that can develop " , to 2025, china is new-style store can dimensions of machine of accumulative total outfit should achieve 30GW above. Up to by 2021, china is new-style store can install machine dimensions to be 5.76GW only. This means 4 years a growing space that has 5 times above, compound year all increase rate is 51% .
Be like those who press each local government " 945 " program, to 2025 end, add always after new-style store can install machine dimensions to will be as high as 43.7GW.
Store what can build is big carry fast, spread out under the setting in target of double carbon of economic exhausted kind.
Since 2021, chinese fixed assets invests apparent be issued to lower levels, to economy growth brings greater pressure. And begin large-scale Chu Nengji plinth establishment construction, conduce to enlarge total demand, stabilize economy; On the other hand, realize the carbon before 2030 to amount to a peak, the goal that the carbon before 2060 neutralizes, new energy resources must develop greatly. Chinese government plan will be not water and electricity to 2025 but second birth the sources of energy (basically be wind report, smooth hot season) generate electricity occupy arrive than promotion 18% the left and right sides, this scale was 2021 11.7% .
Scene report belongs to intermittence the sources of energy, according to arrange of international the sources of energy (IEA) directive opinion, of intermittence the sources of energy generate electricity occupy than under 15% when, lesser to concussion of electrified wire netting; Occupy than in 15%-25% when, bigger to concussion of electrified wire netting, need introduces store can power source will move peak frequency modulation; Occupy than exceeding 25% , to assure stability of electrified wire netting, all power plants must be configured store can.
Generate electricity in view of photoelectric of wind of the China after 2025 occupy rise than will continueing, 2021 after second half of the year, each district government put forward to deserve to build to building scene cable project store can mandatory requirement, deserve to build scale to be the 10%-20% of project installed capacity.
Store can means includes pump water store can mix new-style store can, hot store can, hydrogen store can, among them, pump water store can occupy than the biggest, new-style store can take second place, new-style store can medium basically be lithium ion batteries store can.
With every GW pump water store can cost is calculated 6 billion yuan, press the program of bureau of national energy resources, to 2030 pump water harbour can the power station should add investment newly to be controlled 500 billion yuan; Press actual construction dimensions, before 2030 will add investment newly to exceed 1 trillion yuan.
Only 2022 first 7 months, already caught give an official but have not the pump water harbour of start working can project, total investment already amounted to six hundred and seventeen billion six hundred and ninety million yuan, exceeded since founding a state, build and be in build pump water labor can the investment amount of the project.
New-style store basically can suffer new energy resources to match compulsively store policy is pulled move, if the project of each district program reachs the designated position entirely, according to new-style Chu Nengping all every GW cost is calculated 4 billion yuan, inside 4 years will increase investment newly 152 billion yuan.
With store what can invest great leap forward not to match is its gain foreground. The main source of Chu Nengli embellish is difference of peak cereal electrovalency, press current price difference, pump water harbour can already can gain, new-style store can need to reduce oneself to build cost ability to break through profit and loss to be nodded evenly further. Besides electrovalency control, power market is not perfect also restricting store can gain channel.
Last year since second half of the year, policy warm wind is ceaseless, enlarge power spot market among them pilot limits and allow new-style store can participating in electric power to assist service market is two the most fundamental policy. Country estimation of sea negotiable securities, to 2025, electric power assists the dimensions hopeful that serves the market to achieve 171 billion yuan.
Pump water harbour can before 2030 add investment newly to pass -727379968
Pump water harbour can use electric energy to take water altitude namely, when using phone, turn on the water again generate electricity, it is cost lowest, application is the at present widest store can means.
Although pump water harbour can cycle of big, construction grows project investment dimensions, and accept landform restriction, but its development speed is breathtaking.
Chinese chemistry and guild of physical power source store the data that can use branch shows, chu Nengxin of Chinese pump water added installation amount to grow 192% compared to the same period 2021, achieve 5.3GW; 2022 only first half of the year, pump water Chu Nengxin adds installation amount to achieve 8.01GW.
Bureau of national energy resources is right pump water harbour can the program is to 2025 installation amount exceeds 62GW, achieved 120GW 2030, but the dimensions of real fall to the ground is met probably Yuan Chao hereat.
Fourth blaze chapter was in president of limited company of group of construction of Chinese electric power on June 13, 2022 " People's Daily " publish an article to point out, "945 " during China will implement pair of 200 projects, in the whole nation start working of 200 city county builds labor of 200 above pump water can project, start working target is 270GW.
In July 2022, chief is being accepted related bureau of national energy resources " Chinese the sources of energy signs up for " when interviewing, express, "945 " but harbour of approve pump water can install machine dimensions 270GW, always invest 1.6 trillion yuan, involve 28 provinces (area, city) with Xinjiang production builds large unit.
Pump water harbour can build cycle to be 4 years - 5 years, if " 945 " during the start working target of 270GW can come true, before 2030 can total put into production, china already had the outfit machine dimensions of 39.8GW by 2021, after adding in a word, the dimensions of general assembly machine 2030 will exceed 300GW.
Data of referenced associate with, pump water of Chinese every GW store can cost is controlled for 6 billion yuan, this is meant 1.56 trillion yuan or so need to increase investment newly before 2030.
"945 " time paragraph to arrived 2021 2025, mix according to net of international the sources of energy store can first not complete count, came 2021 by July 2022, already the pump water harbour of start working can the power station is 17.6GW, invest one hundred and fifteen billion one hundred and ninety-six million yuan, had finished bureau of national energy resources " 945 " the majority task of the program.
But the construction pace of the power station that take labor does not have slow down not only, still accelerating instead.
From 2022 arrive first by July 2022, already caught give an official but have not the pump water harbour of start working can the project has 102, 126.9GW of general assembly machine, always invest six hundred and seventeen billion six hundred and ninety million yuan. The investment of give an official of these 7 months, exceeded the pump water harbour since founding a state can total investment.
Arrive from 1958 by July 2022, the pump water labor that start working of Chinese add up to built 91.38GW can, investment amount is four hundred and ninety-nine billion three hundred and eighty-one million yuan.
Pump water harbour can the power station invests and the main force of operation is electrified wire netting, electric power state-owned company.
Up to by 2021, china is carrying pump water harbour can in the power station, 64.56% what the power station below banner of national electrified wire netting takes total installation amount, southern electrified wire netting is occupied 23.2% . From the point of construction program, the construction scale of group of national electrified wire netting, southern electrified wire netting, 3 gorge is the largest.
New energy resources matchs compulsively store pull move new-style store can invest
Change according to national hair appoint, the program that bureau of national energy resources announced in July 2021, new-style store can install machine dimensions to will amount to 30GW to 2025. Since 2022, partial province was released in succession respective new-style store can " 945 " program, after adding in a word, to 2025 the whole nation installs machine dimensions to will amount to 43.7GW.
Up to by 2021, the whole nation is new-style store can install machine dimensions to be 5.76GW, balance 37.94GW.
According to China store can statistic of net of net, national energy resources, 2022 first half of the year, china store can when those who grow 2 hours is new-style store can project, the project always contracts average quoted price covers with tiles for every 1.81 yuan, every GW cost is convert 3.6 billion yuan or so. August 2022 20 arrive 26 days, average quoted price covers with tiles for every 2.29 yuan, every GW cost is convert 4.586 billion yuan, the article takes intermediate cost every GW cost 4 billion yuan.
With this computation, if the project of each district program reachs the designated position entirely, arrived 2022 2025, of China new-style store can will increase investment newly 152 billion yuan.
Current, china is new-style store basically can be electrochemistry store can. According to ZhongGuanCun store can data of industrial technology alliance, 2021 Chinese electrochemistry store can dimensions of machine of accumulative total outfit is occupied new-style store can scale is 96.7% .
2021, chinese electrochemistry Chu Nengxin adds installation amount to grow 135% compared to the same period; 2022 first half of the year, grow 70.19% , add installation amount newly to be 0.39GW, only " 945 " the 1/10 that program growth measures is controlled.
Future, new-style store can invest whether as scheduled be born, where does main driving force come from?
New-style store basically can match with Yu Xinneng source store, power source side assists side of service, electrified wire netting store can, user side store can. Chinese electrochemistry and guild of physical power source store the data that can use branch shows, new-style first half of the year 2022 Chu Nengxin adds outfit machine to be in of 4 kinds of afore-mentioned application occupy than be 39% , 30% , 21% , 9% .
Among them, the investment main body of power source side basically is dispersive the firepower power plant in each district, main body is differ, its invest behavior to reach its to be opposite new-style store can pull traverse to spend, it is not clear to still look at present.
And side of electrified wire netting store can invest with infrastructure of electrified wire netting relevant. Promote before the investment of Chinese electrified wire netting is compared this year two years significantly, 2020, 2021, 2022 first half of the year, the forehead of investment of infrastructure of Chinese electrified wire netting that finish is added compared to the same period fast it is respectively - 6.2% , 1.1% , 9.9% . But overweight of side of investment of electrified wire netting is special high-pressured construction and pump water harbour can be built, can be in how old pull on degree move new-style store can invest not clear also. 2022 first half of the year, chu Nengxin of side of Chinese electrified wire netting adds installation amount compared to the same period fast for 30.52% .
User side store what basically can point to is user of industrial and commercial enterprise installation is new-style store can system, use peak cereal electrovalency to need an advantage. But user side store can investing principal part is enterprise of industry and commerce, its invest motivation to be needed metabolic influence by peak cereal electrovalency, the limitation that also is not perfected by system of market of current China power, be opposite at present new-style store can help motive force not strong. 2022 first half of the year, new-style Chu Nengxin adds Chinese user side installation amount glides compared to the same period 0.02% .
Short-term in light of, new energy resources matchs store right new-style store can invest help motive force the biggest, new-style Chu Nengxin increased this field first half of the year 2022 outfit machine increases compared to the same period 128% , growth trend is very clear also.
On one hand, in field of new energy resources, new-style store can the puissant support that application won policy.
2021 since second half of the year, each district government rolls out policy in succession, investment of will new energy resources and store can invest photograph link up with, project of requirement new energy resources matchs compulsively store, or the way that gives grading to tilt when the project is examined and approve is encouraged match store.
The new energy resources that major province asks to be added newly generates electricity the project is configured store can, scale not under generate electricity 10% of project installed capacity, store can equipment is continuous store can when long should achieve 2 hours of above, and other places of Inner Mongolia, Hunan, Henan, Guangxi, of the requirement match store scale achieves 15%-20% .
On the other hand, installation amount of Chinese new energy resources and investment growth are rapidder. 2022 first half of the year, the accumulative total installation amount that Chinese wind report and smooth hot season generate electricity grows compared to the same period respectively 17.2% with 25.8% , achieve 342 million kilowatt and 337 million kilowatt. And change according to national hair appoint combined print and distribute in June 2022 with the 9 ministries and commissions such as bureau of national energy resources " " 945 " but second birth the sources of energy develops a program " , to 2025, chinese wind report and capacity of aircraft of general assembly of Guang Fufa report should achieve above of 1.2 billion kilowatt, than growing one at present times.
Investment of Chinese smooth hot season is current high speed grows. 2021, chinese Guang Fuji builds investment to finish the forehead to grow 34.9% compared to the same period originally, 2022 first half of the year, add compared to the same period fast promote substantially 283.6% .
Investment of Chinese wind cable glides somewhat. Outfit tide is grabbed to overdraw ahead of schedule before this the influence of the market, infrastructure investment completed Chinese wind report 2021 the forehead glides compared to the same period 7.9% , glided compared to the same period first half of the year 2022 31.4% .
But will look from circumstance of invite public bidding of wind cable industry, wind report invests and increase outfit chance newly or will 2022 second half of the year is greeted rebound. Basis east statistic of Wu Zheng certificate, 2022 first half of the year, chinese wind report makes public dimensions of invite public bidding to exceed 50GW, adjacent already the invite public bidding of annual 54.15GW was measured 2021, predict report of annual China wind enrolled scalar quantity to exceed 100GW 2022.
Taking one with another, be quickened as generation set of new energy resources and net, electrochemistry Chu Nengxin adds outfit machine to also will increase considerably.
Current, new-style store can enrol scalar quantity to already presented ascendant trend. Basis store can with power market count, in May 2022, in June, new-style in July store can the project wins the bid total dimensions is 0.87GW, 0.66GW, 0.97GW respectively. According to negotiable securities of the Yangtse River and country of couplet negotiable securities forecast, chinese new-style Chu Nengquan year add outfit machine newly to add scooter compared to the same period 132% , installation amount achieves 5GW left and right sides.
Pump water harbour can investment redound already had assure
No matter be pump water harbour,still can be new-style store can, theoretic say, the most fundamental profit pattern is low buy sell high -- charge in low electrovalency period of time, sell in tall electrovalency period of time piece, earn electrovalency difference.
But Chinese electrovalency gets governmental control, electrovalency rises very hard considerably, the government that saves greatly with report each still has the strong demand that reduces electrovalency.
Chinese average electrovalency is inferior also. According to data of national electrified wire netting, come to China for years average electrovalency only prep above 2 in 35 OECD country.
Chinese power market is diseased still also, electrovalency is double track is made, cent fixes a price for governmental price and market, the whole nation has half n only is to pass the market to trade. 2021, the electric power that Chinese market fixes a price trades n 3.8 trillion kilowatt hour, occupy whole society to use n 45.46% ; In January 2022 - July, this scale promotes 60% .
Market price trades cent is in trade for a long time and over-the-counter trading, with in trade for a long time give priority to, the market of 80% traded 2021 n is in trade for a long time. In trade for a long time according to the many day, month, season inside the month, year for cycle, decide electrovalency according to supply and demand. Spot market can be begun a few days ago, in a few days, real time trades, dividing area in the ministry at present pilot.
Another part n of China is fix a price by the government, include to be classified according to voltage grade, press classification of the category that use phone, two make electrovalency, electrovalency of peak cereal time-sharing.
Electrovalency is controlled be not being perfected with the market is block up store the stumbling block that can develop.
From pump water harbour can look. Investment amount is large, pay back period is long, this brings about pump water harbour can the investment main body of the power station is given priority to with the state-owend enterprise, civilian look forward to is very few.
In developing a process, pump water harbour also can form a variety of operation mode. Include: All of electrified wire netting once battalion business accounting, rent make pattern paying fee, two make electrovalency pattern.
The pump water harbour of inchoate construction can the power station is electrified wire netting is accessary. Change according to national hair appoint released 2004 " about pump water harbour can management of power station construction concerns an issue " , pump water harbour of China can power station in principle invests construction and operation management by enterprise of electrified wire netting, its construction cost brings into electrified wire netting to run cost with moving cost, unite check and ratify.
After 2014, pump water harbour can the power station moves toward the market gradually. National hair changes appoint harbour of clear 2014 pump water can be provisional two make electrovalency policy (capacity electrovalency + n electrovalency) , capacity electrovalency fixes a price by the government, according to make up for power station fixed costs + allow the principle check and ratify of accrual; Harbour of clear in April 2021 pump water can n electrovalency is formed with market competition means.
Specific for, harbour of some pump water can power station be subordinate to belongs to electrified wire netting, manage business accounting by electrified wire netting; Some independence are managed, get the regular income that rent every year from province power company, this money by area inside generate electricity enterprise of enterprise, electrified wire netting and power user in proportion apportion is assumed. Pump water harbour can after the power station gets renting income, the expense that deducts a power station is gain. Daily, pump water harbour can mix with report generate electricity to need not spend money to also do not receive fund already, operation serves an activity to listen to be arranged from power company, offer for electrified wire netting include to move peak, frequency modulation inside all sorts of auxiliary services.
The pump water harbour that carries out two to make electrovalency can power station, get capacity electrovalency income every year according to installed capacity; The price of capacity electrovalency, according to pump water harbour can yield of interior of gold of capital of power station investment 6.5% business accounting.
Include to move peak, frequency modulation in what make sure the electrified wire netting that finish gives inside besides all sorts of auxiliary servive routine, when the power station still is using electric trough, pump water harbour can use cheap electric pump water, carry out report generates electricity when using electric height, gain the income with poor price of peak cereal electrovalency, namely n electrovalency income. Pump water harbour can the capacity electrovalency of the power station is decided by the government, and n electrovalency is decided by the market.
Change according to national hair appoint released in April 2021 " about perfecting pump water harbour further can the opinion that power station price forms a mechanism " , pump water harbour can n electrovalency, be in the place that power spot market runs, according to spot market price and regular settle accounts; Be in the place that power spot market has not run, pump water harbour can purchase electrovalency to generate electricity according to coal fired of fiducial price 75% carry out, also can form the price through means of emulative invite public bidding.
Current, the electrovalency difference of countrywide limits can have supported pump water harbour can power station gain.
According to net of international the sources of energy, Jin Feng low carbon the sources of energy designs the data of the academy, in January 2022 - in July, the difference of electrovalency of average peak cereal of the 28 city of countrywide that visit an area is every to spend report about 0.7 yuan or so, and pump water harbour can of the power station generate electricity cost spends report for every about 0.2 yuan - 0.3 yuan.
On the whole, at present harbour of Chinese pump water can the power station basically still relies on capacity electrovalency to make money, the profit that n electrovalency contributes is occupied than still low. Network new source controls the country the pump water harbour of an operation can the 2/3 left and right sides that power station installed capacity takes the throughout the country, according to China achieve negotiable securities to calculate, n electrovalency gives a country the gain that network new source accuses a contribution, take its gross profit only 15% the left and right sides.
New-style store can profit pattern has not run
Price respect, from the point of countrywide limits, china is at present new-style store can medium occupy than the biggest phosphoric acid Tie Li store can average cost spends report for every 0.6 yuan - 0.8 yuan or so, referenced January 2022 - the 28 city of countrywide that visit an area are mean in July the peak cereal electrovalency that every degrees of report controls 0.7 yuan is poor, just can achieve profit and loss to balance a line constrainedly (according to net of international the sources of energy, Jin Feng low carbon the sources of energy designs academy data) .
National hair changes appoint, bureau of national energy resources released in March 2022 " " 945 " new-style store can develop executive plan " in put forward, to 2025, electrochemistry store can specifications should promote further, systematic cost should reduce 30% above.
From the point of fractionize market, market mechanism is not perfect also cause a lot of problems.
It is regular ambiguous bring about profit pattern inaccuracy to decide. Store can combine with generation set mostly, use at improving the performance of power source, promote offer of disappear of new energy resources especially. But why does Chu Nengru participate in electrified wire netting attemper, the regulation that how shares auxiliary service market is ambiguous, gain channel is narrow, this brings about Chu Nengli to use rate is inferior, appear even store can equipment " bask " circumstance.
China store can the net reported in June 2022, most new energy resources builds unit general store can inspect " package " , level is purchased in equipment, adopt " minimum price " win the bid means is compressed purchase cost, oversight product safety and function, building phase, take no account of store the interface design that can share power market, after put into production also mostly will store can empty buy " bask " .
The 2nd, high investment cost cannot be digested through raising electrovalency. Power source side store basically can use at providing the auxiliary service such as tone peak, frequency modulation for power system, its invest and operation cost basically is assumed by electrified wire netting, cost dredge is difficult.
For instance Changsha batteries store can demonstrative project of power station first phase, invest 330 million yuan of construction by national electrified wire netting, total dimensions 60MW/120MWh. This project joined movement in March 2019, although land cost is free, and took the pattern that batteries hires, charge of loss of cost of the construction inside Dan Jiquan lifecycle, moving cost, moving n and carry dimension cost are added always arrive one case, amount to cost per kilowatt hour of the electricity generated by WECS still is as high as 1 yuan. Its are annual operation cost is as high as 54.41 million yuan, its are annual poor income of peak cereal electrovalency is 18 million yuan only, project year deficit makes an appointment with 32.81 million yuan.
The 3rd, in user side, store basically can use at with linkage of user of industry and commerce, through peak cereal electrovalency difference achieves earnings, income is more onefold, and be affected easily by shutdown of user of industry and commerce.
For instance, limited company of equipment of Zhuhai watt power the user side of some 2MW/4MWh store can power station, installation is in side of user of industry and commerce, with the user cooperative operation shares profit. If the user uses 1200 degrees of phone every year, store can the power station can need the income that gains 1.55 million yuan through peak cereal electrovalency, the side of 556 thousand yuan of demand that can obtain electrified wire netting to give additionally answers income.
But below this kind of mode, once the user uses n wave motion, store can the accrual of the power station also will fluctuate subsequently.
For example, arrived 2017 between 2019, south Zhejiang Inc. of power source motivation (say below 300068.SZ south power source) in area of garden of Jiangsu Zhenjiang chemical industry investment built 6 store can power station, but Jiangsu province published policy to clear in November 2020 low end small effect and safe environmental protection cannot stabilize the industry that amounts to mark, the user drops suddenly with n, bring about a power station to be in 1-2 month appeared 2021 inadequacy of offer of serious n disappear, earnings falls, south power source is forced to be opposite store can the power station undertakes asset reduces a cost.
Policy warms wind frequency is blown
Chinese government has realized afore-mentioned problems, issued a certain number of policy that solve a problem in succession.
The first, play difference of electrovalency of big peak cereal, promote Chu Nengying advantage ability.
National hair changes appoint released in July 2021 " the announcement about mechanism of electrovalency of farther perfect time-sharing " , requirement each district combines actual condition to carry out aiguille electrovalency mechanism on the foundation of peak cereal electrovalency, aiguille electrovalency is in peak paragraph in principle of scale of float of electrovalency foundation before last not under 20% . According to statistic of Polaris power network, rose on July 1, 2022, the whole nation has 27 provinces city to begin to carry out aiguille electrovalency.
The 2nd, enlarge power spot market pilot limits.
Spot market can let the price fluctuate in real time along with supply and demand and cost rise, be helpful for Chu Nengling be being caught alive everyday peak cereal electrovalency is poor.
Without spot market, mean electrovalency much inside the month day, month, season, year inside time cycle changeless, electrovalency cannot be mirrorred neatly generate electricity the change of cost. Had spot market, electrovalency can be reflected in time everyday, of every hour generate electricity cost and the pressing rate that use phone, let store can better profit.
For instance, carrying out the Shandong province of electric power over-the-counter trading, the negative electrovalency that appeared 22 days in April 2022, because new energy electricenergy production goes up greatly inside period of time, and the demand that use phone is not exuberant, the independence that Shandong saves store can the circumstance that the power station realized to charge in order to lose electrovalency.
China decides first power spot market at was being knocked 2017 pilot, include area under administration of southern electrified wire netting (Guangdong starts) , Meng Xi, Zhejiang, Shanxi, Shandong, Fujian, Sichuan, Gansu Province, move at imitate is being started to try in the round by June 2019.
Spot market of the 2nd batch of power is pilot decide at was being knocked in April 2021, include Shanghai, Jiangsu, Anhui, Liaoning, Henan, Hubei, its imitate trades to already was started at arriving in January 2022 between August respectively.
The over-the-counter trading between the province tries at was being started in southern electrified wire netting in June 2022 move, implementation arrives by Guangdong the power spot market of Yunnan, Guizhou, Guangxi, Hainan crosses an area to cross a province to trade.
National hair changes appoint released in January 2022 with bureau of national energy resources " about accelerating construction the whole nation unites opinion of guidance of power market system " , put forward 2025, system of market of countrywide centralized electric power is initial build, in electric power operation of design of unifinication of market of long-term, merchandise on hand, auxiliary service, combination, cross a province to cross area resource to commercialize configuration and green electric power to trade dimensions rises significantly. This pair is straightened store can trade mechanism and price mechanism will have a help greatly.
The 3rd, reduce cost, increase allowance.
Change according to national hair appoint, bureau of the sources of energy in June 2022 " about be being driven further new-style store can share electric power the market and attemper the announcement that use " , independent store can power station to power transmission of electrified wire netting, derate its charge of n be defeated by distribution price and governmental sex fund to reach add. This can let new-style store can cost per kilowatt hour of the electricity generated by WECS reduces 0.1-0.2 or so yuan (according to Jin Feng low carbon the sources of energy designs academy data) .
On September 2, 2022, shandong province hair changes appoint, Shandong of bureau of bureau of Shandong province the sources of energy, national energy resources superintended the office to combine print and distribute " save about promoting Shandong new-style store can set an example a certain number of measure that project health develops " , put forward to offer new-style Chu Nengrong quantity compensation, its compensate standard of short duration to press the independence in power market regulation store can monthly can amend a standard with the capacity 2 times carry out.
According to statistic of Polaris power network, arrive from 2018 at the beginning of August 2022, already 24 save city to put forward clearly to be opposite store can investment and operation extend allowance.
The 4th, right store can equipment moves strengthen superintend. For instance, superintendency office of Jiangsu of bureau of national energy resources released on August 15, 2022 " Jiangsu electric power and the net runs management to carry out detailed rules " , specific requirement store can the power station must be subject to attemper of the orgnaization attemper management, whole to self-regulated of arrogate to oneself store can of the power station initiate the action that stop and charges discharge switch pattern, place in order to fine 100 thousand yuan.
The 5th, explicit new energy resources matchs store the regulation that shares the market.
Hair change appoint, bureau of national energy resources goes out in the announcement middle finger June 2022, what exist with deserving to propose a form is new-style store can project, can capacity one divides into two, one part uses service new energy resources to generate electricity, the relevant system such as metric inside the station that finish, control is transformed and accord with relevant technology to ask the circumstance falls, match the combination of other type power source that propose with place, regard a whole as, make sure accept of disappear of new energy resources is used; Another part can inspect independent capacity, share power market. Condition of contented and relevant technology, accord with relevant requirement, and have corporate organization new-style store can project, can turn for independence store can. (involve scene fire and water store of many can complementary unifinication store can project except)
The 6th, open the entrance door of auxiliary service market.
From the point of countrywide limits, electric power assists a service is a kind of planned dispatching essentially, be not complete market action, but its are potential market space can achieve 171 billion yuan to 2025, current, policy to new-style store the entrance door that can open auxiliary service market, in order to promote new-style store can gain ability.
Electric power assists a service is to participate in main body to move to safeguard power system safety to stabilize, assure electric energy quality, producing besides normal electric energy, transmit, use besides, answer electric power to attemper the service that instruction place provides.
After the basis edits " electric power assists service government measure " , its serve breed to include have rendered great service to serve evenly, without result balance lash-up of service, accident is reached restore a service.
According to statistic of bureau of national energy resources, 1.5% what at present Chinese electric power assists service charge to take whole society total charge of electricity about, about 75 billion yuan or so. Country estimation of sea negotiable securities, 3% what can take whole society total charge of electricity to dimensions of auxiliary 2025 market, about 171 billion yuan.
On December 21, 2021, bureau of national energy resources edits released " electric power assists service government measure " , enlarged the principal part that auxiliary service supplies. The main body before this is only and network power station, but after editing, new-style store can, bear of industry of power plant of provide for oneself, traditional Gao Zaineng, industry and commerce can interrupt bear, electric car to charge network, aggregate trade, fictitious power plant, also be maintained to be the principal part that auxiliary service supplies.
"Was equivalent to opening an entrance door, before is power plant, him electrified wire netting plays, alien is participated in very hard, new-style now store can OK also enter the market to make money. " Beijing general can area of Asia-Pacific of limited company of century science and technology selling manager Kuang Zhen benevolence right " finance and economics 11 people " say.
Certain province still released deflection at store can executive policy. For example, superintendency office of the sources of energy of Yunnan of bureau of national energy resources was released in August 2022 " Yunnan Hei Qi moves auxiliary service market to trade regular (ask for an opinion to stalk of grain) " , have a requirement clearly store can can participate in Hei Qi to use auxiliary service market independently, if many markets main body declares the value identical, go out clear above all store can. (a kind when the service assists when Hei Qi is moved, after showing in electric power the system halts use because of breakdown, discharge drives the service that starts without the generation set from the ability that start)
Additional, guizhou, Chongqing, Guangdong, Guangxi, Jiangsu, Beijing also will arrive in June respectively between August, released encourage store the relevant file that can share auxiliary service market.
Specific executive measure also begins to be released in succession. On September 2, zhejiang province was released " Zhejiang saved main body of tripartite independence to participate in electric power to assist service settle accounts to try traffic programme 2022 (ask for an opinion to stalk of grain) " , made clear new-style store the regulation that can participate in auxiliary service in spot market, include: New-style store can OK offerred service is to rotate reserve, peak of peak of the attune that cut a peak, the attune that fill cereal; Begin in order to commercialize a form, declared a few days ago, go out clear, call in a few days; Participate in rotate reserve of the service store can, can obtain call the capacity is compensated and win the bid the capacity compensates two income (be similar to pump water harbour can capacity electrovalency and n electrovalency) .
The policy of these 6 specific aim is adjusted, will clear improvement store the redound foreground that can invest.
Appendix: 5 kinds " be not the mainstream " store can technology
Chu Nengcun is in a variety of technology courses, current mainstream technology line is pump water harbour can be mixed lithium ion batteries store can.
Up to by 2021, pump water harbour can installation amount is occupied store 86.3% what can install machine gross, the scale that future plans to invest is the largest also; Lithium ion batteries store can occupy store 11.2% what can install machine gross, it is new-style store can main configuration, but the defect with existence inadequate security.
Load one's writing with fancy phrases of many lithium ion batteries is together, appear easily safe accident. According to the statistic of smooth old negotiable securities, arrive from January 2011 in April 2022, global add up to happens 34 cases store can incident of power station explosion, among them 32 it is lithium battery.
On June 29, 2022, bureau of national energy resources is in " 25 keys that prevent electric power to produce an accident ask (2022 edition) (ask for an opinion to stalk of grain) " put forward: "In large chemistry store can the power station must not choose 3 Yuan Li batteries, sodium sulfur batteries, unfavorable choose ladder second use dynamical cell " .
This is meant other store can the technology is possible the portion of batteries of ion of lithium of race to control, in store can the market holds position, even predominate.
It is below 5 kinds main " blame mainstream " store can technical course.
1.Compress air store can: Need is specific geological condition
According to ZhongGuanCun store can data of industrial technology alliance (similarly hereinafter) , up to by 2021, china compresses air store can machine of accumulative total outfit is 0.18GW.
Compress air store can the principle is, use electric energy to compress air in well of mine of saline acupuncture point, metal, oil gas, colliery well or pressure vessel; When using phone, release compress air, drive air turbine to expand machine generate electricity.
Compress air store can the advantage is to discharge oneself rate is low, day-to-day operation cost is low, service life of equipment is long, defect is investment cost is high, suffer be confined to the geological condition of sealed burrow.
On May 26, 2022, china compresses air the first times store can acupuncture point of salt of altar of gold of Jiangsu of national demonstrative project compresses air store can the power station is formal and net put into production, this is by China China can, in the much family property such as university of saline group, Tsinghua, three-dimensional chemical industry learns to grind unit, through 10 years two years of research and development, construction become independent finishingly store can power station, first phase store can install machine 60MW, long-dated program 1000MW.
" finance and economics 11 people " basis store can first data statistic is arranged, 5 provinces compress air inside limits store can the demonstrative project of batteries is as follows:
2.Melt salt store can: Ask to material tall
Up to by 2021, chinese melt salt store can machine of accumulative total outfit is 0.55GW.
Frit salt is salt kind (salt of the halide of alkali metal, alkaline-earth metal, nitric acid, sulfate) the melt body that after fusing, forms, be a kind conduct heat admirably store hot medium. Melt salt store can principle, use electric energy to heat namely frit salt, when need uses phone, salt of frit of recycle high temperature and water heat exchange, turbine of generation vapor drive generates electricity.
This low, life grows melt salt Chu Nengcheng, but incidental liquid leak, and be fought to material of device of accumulation of heat corrode a requirement tall.
2022, what many province announced a plan to build is new-style store can set an example project list, among them, the technical line that the project announced in the list of Zhejiang province, Shandong province, Heibei province, Shanxi province, Qinghai province, " finance and economics 11 people " basis store can first data statistic is arranged, salt of the melt inside 5 provinces limits store can set an example the project is as follows:
3.Vanadium current batteries: Suit large-scale store can, but raw material cost tall
Up to by 2021, batteries of Chinese vanadium current store can machine of accumulative total outfit is 0.05GW.
Vanadium current batteries store can the principle is, use vanadium oxide and electrode contact to produce electrochemistry to react, let electric energy of chemical energy translate into, perhaps let chemical energy of electric energy translate into, the pump that outside passing, receives, will store electrolyte carries the vanadium oxide inside storage tank to pile to batteries inside, undertake electrochemistry reacts, recycle flow returns storage tank later, form close loop, realize the process that charge and discharges thereby.
Vanadium batteries but expansibility is good, want to increase electrolyte to be able to increase additional installed capacity only, and its security is better, accordingly its suit relatively large-scale store can. Negotiable securities of Shen Yinmo country, smooth old negotiable securities, trade of short for Zhejiang Province thinks, 2025 around, batteries of Chinese vanadium current store can year add installation amount newly to be able to achieve 2.13-3.5GW.
But its biggest weak point is price taller, according to current price, the half of its totle drilling cost needs to be used buy vanadium oxide electrolyte, bring about its are at present integrated Chu Nenggui of batteries of ion of price comparing lithium one times.
But in applying actually, the pattern that can use financing to rent is reduced buy the home to pay pressure. For instance, chinese general can roll out the pattern that electrolyte financing hires, let buy the home need not one-time pay electrolyte buy fare, pay a few rent every year however, make vanadium batteries store can price reduces as ionic as lithium batteries store can same standard.
In August 2022, the current of Dalian 100MW/400MWh vanadium that invests 2 billion yuan store can move peak power station to merge into formally Liaoning electrified wire netting, undertake be debugginged finally, predict to commercial operation is thrown by September. The first state level that this is construction of approval of bureau of national energy resources is large and chemical store can set an example project, also the vanadium current batteries with the greatest whole world store can power station.
" finance and economics 11 people " basis store can first data statistic is arranged, batteries of current of the vanadium inside 5 provinces limits store can demonstrative project is as follows:
4.Batteries of Tie Ge current: Vanadium batteries challenger
Batteries of iron chromic current store can principle and vanadium current batteries store can similar, the biggest distinction is uses electrolyte data it is Tie Hege, cost is lower than vanadium. Basis western the data of negotiable securities, in other hardware condition changeless circumstance falls, vanadium oxide electrolyte occupies Chu Nengcheng of vanadium current batteries this half, 9% what iron chromic material takes battery of iron chromic current only.
Current, batteries of iron chromic current store can return in Chinese application less, " finance and economics 11 people " basis store can first data statistic is arranged, batteries of chromic current of the iron inside 5 provinces limits store can demonstrative project is as follows:
5.Flywheel store can: The rate that start is rapid, rather he store can match use
Up to by 2021, flywheel store 0.01GW can is in installed capacity of Chinese accumulative total.
The rotor that flywheel Chu Nengli rotates with the high speed in low attrition environment will store energy. Its principle is, use electric energy to quicken flywheel, store mechanical energy of electric energy translate into, when need uses phone, flywheel drives generation set, electric energy of mechanical energy translate into.
Flywheel store can the advantage is energy density the tall, rate that start is rapid, but defect is discharge time short. For instance data center cuts off the power suddenly, need store can the system is started quickly, lest cause data to lose, suit flywheel store can, dan Fei annulus store can can power supply ten seconds, need and other store can cooperate to use.
" finance and economics 11 people " basis store can first data statistic is arranged, the flywheel inside 5 provinces limits store can demonstrative project is as follows:
