2014 is about to pass, and the new year is coming soon. Looking back on the power industry this year, the power grid companies always seem to be able to hold the heart of the power workers. From the beginning of the debate between UHVDC and the exchange project, the Energy Bureau and the two Power Grid Corp signed the task of constructing the transmission channel outside the air pollution control area, and then to the development and Reform Commission in Shenzhen to carry out the pilot project of transmission and distribution tariff reform. One pile and one piece are carried out around the two themes of ultra high pressure and electricity change.
Although the UHV project has been disputed continuously, it still can not hold back the enthusiasm of the national grid construction of the special high voltage. In mid November this year, the national network of the two cross (Huainan - Nanjing - Shanghai, Ximeng - Shandong, Ningdong - Zhejiang) three lines to start building the next year, the State Grid will continue to force the UHV construction, and strive to start the "five pay eight straight UHV project 13. More than that, in the middle of this year, media reports reported that the State Grid will open four fields to introduce social capital, including distributed power grid connected, electric vehicle charging and switching electricity market opening, pumped storage power plants, peak load regulation and frequency modulation energy storage projects will be open to investment. Is it really good for the enterprises of the private enterprises to take this decentralization?
Cloud GUI power transmission scheme for many years also settled in the game this year for dust, southern power grid, cloud power transmission Guangxi planning has been a long time, the final agreement can be reached for it. Polaris distribution small does not enumerate the ten network news, the details are as follows:
(1) the UHV power grid air Commander: DC or AC?
UHV power grid can achieve large capacity, long distance and low loss transmission. From the output of energy to the demand side of the market, UHV transmission has become a consensus. In fact, the construction of UHV transmission lines has been lagging behind schedule since last year. It is the choice of DC or communication that affects the construction process.

In February 19th, it was said that eight UHV lines had been assessed by third parties and sent to the State Energy Bureau. As early as last month's 2014 national energy conference, representatives of the industry did not dispute about the planning of UHV transmission lines. There are many disputes over UHV transmission projects.
(2) the state grid does not avoid the disclosure of the "five vertical and five horizontal" lines of the 27 lines of the UHV dispute
In the 2014 Forum on Power Planning Development held in April 2nd, the head of the State Grid did not shy away from the recent controversy over the UHV transmission line construction. Instead, it revealed the latest planning progress of the five vertical five transverse 27 UHV transmission lines. It is said that the move would be better to deliver electricity from the west to the East and the middle.
But with the increasing haze of Beijing, Tianjin, Yangtze River Delta and Pearl River Delta in recent years, the main way of "iron haze" has begun to turn to reduce the use of coal in the region. There is no dispute over electricity generation. From this point of view, UHV is an inevitable choice. At present, the focus of the debate is mainly on the UHV or AC UHV.
(3) the Energy Bureau and the two Power Grid Corp have signed a task book on the construction of air pollution prevention and control of the external transmission channel (with 12 transmission channels)
In order to further refine and implement the plan of strengthening air pollution prevention and control work in the energy industry, recently, the national energy board signed the task of building the transmission channel outside the air pollution control separately with the national Power Grid Corp and the southern Power Grid Corp.
According to the "book" task requirements, the national energy board and the two Power Grid Corp will accelerate Inner Mongolia Ximeng by Beijing, Tianjin to Shandong UHV AC transmission project and other 12 transmission channels outside air pollution control construction. The national energy board will speed up the process of project approval, meet the construction period requirements, and liaise with local government departments to coordinate and solve major problems in the implementation process, and implement various supporting conditions. The two Power Grid Corp should formulate the project schedule separately, clear the target and task of the annual work, implement the responsible person, and ensure that the project is completed and put into production as scheduled.
Twelve transmission channels:
1. Liaoning Suizhong power plant switched to North China Power Grid (+ 500 thousand volts)
2. Inner Mongolia Xilin grille to Shandong UHV communication project
3. Shanghai temple to Shandong UHVDC project in Inner Mongolia
4. Shaanxi yulheng to Shandong Weifang UHV exchange project
The 5. Tianjin Nantes UHV AC project to Mongolia
6. Ximeng to Jiangsu HVDC project
7. Huainan - Nanjing - Shanghai East China power grid north central UHV AC project (April 21st has been approved by the National Energy Board approved)
8. Ningxia to Zhejiang UHVDC project
9. Shanxi to Zhejiang, UHVDC
10. Shanxi Yuxian power plant access to Hebei project (+ 500 thousand volt)
11. Shaanxi Shenmu to Hebei 500KV transmission channel expansion process
12. Southern Power Grid to the west to the East, Lijiang direct transmission of Shenzhen UHV direct current project
(4) the Energy Bureau announced a new power supply for power grid supervision
In March 14th, the State Energy Bureau issued the notice of the Interim Measures for the access to power grid supervision by the new power supply. This approach applies to the newly built power projects approved by provincial investment departments (including "Filing"), including the hydropower generating units with grid connected generating units and hydro electric power stations, and to access the power grid supervision.

The new power grid including supervision on the new power grid project related work system, grid service, access for new power projects and supporting transmission project (also known as the "access system project" or "grid project") synchronous construction situation and the related information on the public supervision.
(5) the audit results of 21 transmission and transformation projects from the west to the East (Quan Wen)
According to the provisions of the "Audit Law" in People's Republic of China, April 2013 to July, the Audit Department of Electric Power Engineering Nanjing East to Shandong - 660 thousand volt DC power transmission demonstration project 21 project (see Annex 1) the investment and construction, operation and management of the audit.
The following main problems found in the audit process: Construction in violation of the provisions of the bidding, equipment and materials procurement and other business issues that exist in failing to tender, strict control of project investment, taking of construction funds little Treasuries problem etc..
(6) the national network introduces the opening of the open four fields to the social capital industry and refers to its burden
In mid May, Economic Information Daily reporters learned from authoritative sources, the national network will open four areas classified introduction of social capital, the implementation of market opening of distributed power grid, electric vehicle charging, pumped storage power station, peaking FM storage implement investment projects are open, and the "UHVDC money king" although better has been considered, but ultimately failed to enter the open list.

The long term cooperation framework agreement between Yunnan and Guangxi is signed in Yunnan
As early as 2009, the Southern Power Grid proposed cloud transmission to Guangxi and planned to put into operation in 2013, which was also brought into the power development plan by Guangxi. But cloud electricity sends cinnamon but is "late" for a long time, and behind it is the game of many interests.
Yunnan believes in AC transmission from local electricity and economic development, while the Southern Power Grid chooses direct current transmission for planning and cost. Chief Chinese energy expert Han Xiaoping told reporters that Yunnan should protect the tax, protect the local power advantage, but now countries have strict control of high energy consuming industries, and environmental pressure, can not only send electric cloud, one of the reasons may be the final mutual agreement of the parties. "Electricity price is also one of the core of the game." Yunnan Nujiang Hydropower Enterprise Association Secretary General Xu Zhenduo believes that because the price problem, cloud power transmission Guangxi has not reached an agreement, the key is the problem of the distribution of benefits. For example, the price of Yunnan's hydropower to Guangdong is only 0.39 yuan / kWh, and it is not better than the local protection price for small hydropower.
(9) the Commission to carry out the pilot reform of electricity transmission and distribution grid in Shenzhen: wheeling charge (Quan Wen)
In November 4th, in order to explore the establishment of an independent transmission and distribution price system and promote the marketization of electricity market, the NDRC issued the notice on the pilot reform of transmission and distribution price in Shenzhen, officially launched the new round of transmission and distribution tariff reform in China.
The circular pointed out that in Shenzhen, a pilot project of transmission and distribution tariff reform will be carried out in the city, and the current grid enterprises will acquire the profit mode of purchase and sale differential income by relying on electricity purchase and electricity sale, instead of regulating the total income of grid enterprises. That is, the government, based on the effective assets of the power grid, approved the cost and the permitted income, fixed the total income of the power grid, and announced the independent transmission and distribution price. It is clear to actively promote the generation and sales side of the electricity market, electricity transmission and distribution power grid enterprises approved by the government of the wheeling charge.
(10) the national network UHV program continued to expand the first disclosure of "five exchanges and eight straight" on 2015
Although it has been in the dispute, but still can not block the enthusiasm of the national grid construction of ultra high voltage. In 2015, the national grid will continue to build UHV, even bigger than any previous year.
According to the overall plan of the national Power Grid Corp, the project of "five exchanges and eight straight" UHV is started in 2015. This means that 13 UHV will be included in the construction catalogue next year.
The reporter was informed that the first official disclosure of "five pay eight straight UHV, respectively, Ya'an - Wuhan, Zhangbei - Nanchang, West Inner Mongolia - Changsha, Yubei, Yu Heng Long Bin - - Weifang five UHV AC line, and the Jiuquan - Hunan, Shandong - Hulunbeier, Mengxi - Hubei, Jiangxi, Shaanxi Sichuan, Shanghai - East Temple - Shandong, Shanxi - Jiangsu and Ximeng - Jiangsu eight UHV DC project.
The "national Power Grid Corp" five pay eight straight "plan" shows that in high communication, national grid planning including Ya'an - Wuhan, Zhangbei - Nanchang, West Inner Mongolia - Changsha, Yubei, Yu Heng Long Bin - - Weifang five lines.
