No cleaning works and sewage, not allowed to directly into the Lancang River. Builders construction dust and noise, also will take the appropriate measures.

Sun Beijing May 27 (zxs) China National installed capacity increased, current power shortage situation has receded in parts.

the reporter learned from the national grid company, One of this year, when the national power generation capacity 647.3 billion-kilowatt, increase of 15.8% over the same period last year, when the State grid Corporation operating a regional electricity production 542 billion-kilowatt, increase of 16.3% over the same period last year.

in April, due particularly in southern regions of the country more rainfall, the major power plant reservoirs to water increasing, hydro increased electricity tensions had eased in some areas, Fujian did not switch out the energy this month, limit significantly reduced the number of Hunan, Sichuan, Chongqing, Shanghai, Zhejiang, Abendkleider Jiangsu and pull the energy volume has declined. But the impact due to inadequate coal supplies and generator maintenance, State grid system has 14 provincial power grid switch out the energy phenomena, with the advent of summer peak, the tensions in the power supply and demand will be more severe than last year.

according to the analysis, countries introduced in the near future against some sectors low-level duplicate construction, cancellation, higher power consumption electricity industry preferential electric energy price in a series of macroeconomic regulation and control measures to ease a part of the rapid growth of the industry, easing tensions in energy, raw material supply. These measures of implemented will will on mitigation power supply and demand tension situation produced of actively effect, but power supply and demand tension situation still will continued, as summer electricity peak of comes, pull brownouts of area also will increased, power gap will further expanded, grid safety situation will than Shang a years more grim, for this about sector is actively should welcomes peak crossing summer of the prepared work, to maximum to guarantee power effective supply, guarantee grid run security.

Red NET Cheung Sha, May 21 (reporter Kuang Lifang) reporters learned from the working meeting held in Hunan electric power today, by the end of April, Hunan provincial power company system statistical data indicate that the company is owed huge amounts of electricity tariffs, together with other small water and electricity company, the province’s accumulated arrears amounted to $ 2.917 billion, ranks first in the country.

it is understood that since December last year, the provincial government to focus on organs and institutions owing money paid. From the current situation, the effect is not obvious. Ended late April the Province owed over $ 300,000 institutions owe fees totaling $ 23.15 million, representing settlement fell by only $ 8.31 million before action.

Zheng Maoqing Vice Governor of Hunan provincial people’s Government at the meeting stressed that Governments at all levels and relevant departments should further increase the intensity of paid work, implementation of measures to remain outstanding, owed by ensuring that electricity tariffs in cleared prior to the end of June. He said, Executive Office of the provincial Government will focus on tuition and units specialized in supervision and, when necessary, also will be on television, newspapers and other news media for tuition-areas and units for exposure.

industry pointed out that the huge electricity bill arrears, and the resulting power supply enterprises owed purchase electricity power generation enterprises, not only of normal production, operation and construction of electric power enterprise is seriously affected, but also seriously disrupted the normal order of market economy and affect the image of Hunan.

Zheng Maoqing requirements, Governments at all levels and departments concerned should adopt effective measures to urge consumers paying electric rate according to the law, supporting power companies charge according to the law, collection of electricity charges to create a good environment and power supply order. Tariff settlement accelerated power supply enterprise reforms of various users throughout the province gradually Cocktailkleid introduced “after first purchase”. To intensify the destitute and bankrupt enterprises in production and livelihood electricity isolation and transferred power to transform, and funds needed by the power companies, power companies and where the State Government in proportion with the share. To standardize the Corporate bankruptcies and restructuring. Strict implementation of the State economic and Trade Commission, the Central belongs to close bankrupt enterprises of resource-exhausted mine and the views of the relevant provisions of the transfer of power supply system: “bankruptcy bankruptcy during the tariff should be included in bankruptcy fees; bankruptcy following the end of the newly formed company tariffs should not be in arrears. Such as tuition, in principle, by the local Government to urge the power companies pay, enterprises cannot afford to pay and the local government is required power supply, be supplemented by the local government. “Reforming enterprise must bear the original company energy debt, local governments shall not be in violation of the regulations on enterprises owed as bad debts, or to take other forms of evading tariff debts.

Our province is to build wind power for energy power projects, preparatory work has been fully started, provincial development and Reform Commission yesterday to make arrangements.

known as “blue sky and white coal” of wind resources, is an inexhaustible and don’t pollute renewable. Wind power is the use of natural wind, generate electricity by magnetic lines are cut. This is the largest prospect development and commercialization of one of the modern generation, in terms of reducing energy consumption, reducing pollution has a clear role. According to reports, China’s wind-rich, installed capacity in the development of the highest in the world. China wind power installed capacity was only 460,000-kilowatt, national electricity share of the total installed capacity of less than 1%, enormous potential for wind power in China. Countries have been initially identified, in recent years the construction of four 20 or above large-scale wind farm, by 2020, formed 20 million-kilowatt in the country’s power generation capacity.

two years early in my province meteorological evaluation of wind energy resources, initially identified as Datong, Shuozhou, Xinzhou city, luliang, and other parts of the city with a certain degree of power generation such as wind, wind speed conditions, General construction scale of each wind farm proposed for 5 per cent. Accordingly, meteorological evaluation of wind energy, our province has now started planning and site selection of wind farm in preparation, according to requirements of plan will be completed during the year, next year “Eleven-Ballkleid Five” plan started, one after another under construction. Provincial development and Reform Commission has arranged $ 1 million power Fund for preliminary work on the construction of these projects.

according to rough estimates of experts, and built several wind farms, forming 500,000-kilowatt capacity, more traditional thermal power plants, annual savings of six hundred thousand or seven hundred thousand tons of coal-fired, with significant economic and social benefits.

as the power market reform is deepening, how to make full use of market instruments, activist spanned across provincial electricity trading, optimizing the allocation of resources, promote the development of regional economy and society, as right in front of electric power enterprise “solution of equation”. This year, the North China grid company limited made the cross-step, gives this “solution of equation” a nice answer.

on December 20 last year, North China electric power dispatching (Exchange)Abendkleider Center officially, formerly “North China electric power dispatching Bureau” hence the appellation from the historical stage. Detailed criticism both before and after titles of distinction, core landed on the “deal” on the word. If the literal difference is merely a symptom, the institution that is hosted behind the function adjustment of the substance. It is understood that changed its name before the scheduling Board imposed on the North China power grid dispatching management, in accordance with the principle of unified scheduling, grade management, organizing, directing, guiding and coordinating the North China power grid safe, stable, high quality and economical operation. Changed its name to dispatch (Exchange) Centre, it also hosts a involved in cultivation in North China electric power market, promoting province and North China power network in North China power grid and other functions of the electric power and energy transactions between regional power grid. Scheduling (Exchange) Center was established electricity market operation, better regional power resource optimal allocation in paving a smooth sailing.

launch platform: market access to

power leveling most of the past by telephone or by facsimile, time-poor scheme color consistency. Province in North China power network electric energy trading platform adds many new features – quote, fix calculation, tie-line plan adjustment, trading, settlement and information publishing. This platform to conduct annual and monthly and and recently real-time transactions, meet power transactions between North China grid rule requirements. And in the course of trading, through the operation of the market, give full play to the existing capacities of generation and transmission facilities, protection of both supply and demand reasonable return. This has eased tensions in the power situation, reduces the switch out the energy, optimizing the allocation of resources.

3 earlier this month, spring irrigation of Hebei South network load a sudden surge in tension power supply, power generation output a serious shortage of daily peak electricity shortfall amounted to 1 million-kilowatt, near one-tenth of Hebei South network load. In this case, companies taking advantage of the large power grids of North China, the use of spinning reserve capacity of the North China power grid, active power transactions between provinces, timely organization of power support, Hebei province electric power company on March 16 by Beijing-Tianjin-Tangshan power network temporary electricity 400,000-kilowatt, successfully contributed to the province between the electric energy trading platform since the start of trading for the first time.

promulgate rules: standard thinning market transaction

is a gradual power trading market cultivation and development process, cannot accomplish. In particular with regard to all market players involved the operation of the market should have an adaptation period. No rule buchengfangyuan. Market trading rules is to ensure that trading activities in an orderly manner, markets key to the effective operation of the trading system.

as the electrical energy trading platform between provinces started, company and the promulgation and implementation of the North China power grid in North China province electricity trading regulations (hereinafter referred to as the rules). On the rules of provincial power various types of transactions between specific operational processes, transactions, obligations of the parties, as well as their time expressly provided. At the same time, to strictly regulate the electric energy transaction process, has a very strong guiding and operability. After the promulgation of the rules, was launched in North China power network monthly centralized broker transactions between provinces, 14 March completed temporary power transactions, transactions when the charge reaches 47.4 million-kilowatt. Among them, recent transactions 8, live trading 6, including 13 in Hebei South network transactions, transactions when the power 43.7 million-kilowatt, maximum increased for the power of 1 million-kilowatt; and in Shanxi power grid deal 1, when volumes 100,000-kilowatt.

rules under and province between power trading platform of “close” combination, conducive to on real-time run way and power planning for in-depth research; conducive to construction scheduling and market, and security and economic of harmonious, more full to reflected “three public” scheduling principles, improve has grid across province transmission ability; conducive to optimization configuration power and grid two large resources, reduced has pull road brownouts loss, made has social benefit and economic benefits of double harvest.

Follow deployment of national electricity regulatory Commission, positively and steadily promote electric power market reform, after half time preparations, State power Regulatory Commission the South Bureau (“Southern electric administration”) in Guangzhou on December 16 operation formally. This indicates that China Southern power market and market-oriented reform of the regulatory system will take substantive steps.Cocktailkleid

southern China electricity regulatory Commission Council is the local offices of the State electricity regulatory Commission, implementation of power executive law enforcement functions of the institution by the State electricity regulatory Commission administration should. Electricity regulatory Commission, in charge of southern region of southern China including Guangdong, Guangxi, Hainan, Yunnan, Guizhou province 5 provinces electricity regulatory work. Its main functions is: regulatory South regional power market operation, specification power market behavior, maintenance fair competition; regulatory area within power enterprise and power scheduling trading institutions; is responsible for area within power administrative law enforcement, and administrative punishment and administrative litigation, about legal Affairs; is responsible for area within power security and reliability regulatory; is responsible for area within power market statistics and information publishing; management area within power business license; according to law investigated and dealt with area within power Enterprise illegal violations behavior.

southern China electricity regulatory Commission Secretary Yang kun said at the ceremony, covering the 5 provinces and autonomous regions of China Southern power grid, power supply 1 million square kilometers, power service population of around 220 million. Cross-provincial electricity trading since 1993, when the cumulative volumes until the end of 2003 amounted to 103.1 billion-kilowatt. But changes with economic developments and market main body, existing resource allocation means and mechanisms adaptable to needs for power development urgently needs structural reform and mechanism innovation. Southern electricity regulatory Commission, the establishment of the South regional power industry development and market-oriented reform of objective needs.

compared with other regions, southern region electric power industry and power market has its own particularities. First, the Eastern Province (area) of demand load imbalance caused huge economic gap. Second, resource distribution is unbalanced, rich water, thermal power resources in Western, East lack resources. Third, the structure and technology of China Southern power grid is a very complex network, span, from West to East, large capacity, distance, ultra high voltage AC and DC stator connections run power network stability problems.

for this, South electric prison will will from South area of features set off, full consider all province (area) economic development level, and electric price level differences larger of reality, in accordance with the “open up enterprising, rigorous pragmatic, just law enforcement, honest and clean” of requirements, firmly set according to law regulatory of concept, efforts established and maintenance fair, and just of market order, actively maintenance power system security stability run, promoting South regional resources of optimization configuration.
