Distributed energy has many advantages, such as adjustment of peak-to-valley difference, economy, power supply security, loss of power transmission and distribution, low capital density, flexible use, and less pollution, etc. The development of distributed energy will adjust primary energy structure and ensure energy supply. Supply security and solving environmental pollution have a positive effect.
Led Emergency Light have been divided into two heads emergency lights , bulkhead emergency lights , emergency ceiling lights and emergency bulbs . The role of emergency lights is an emergency state evacuating people , generally used in public places . All emergency lights use LED source , its advantages are high brightness , low power consumption , LED lighting effect than the traditional light source energy saving nearly 80% .

The status of distributed energy development
China's distributed energy started relatively late, but its development speed is rapid. By the end of 2012, China had distributed 15,600 distributed power sources into production. In 2013, only distributed photovoltaic power generation in China reached 3 GW. At the same time, China has built distributed energy projects in Beijing, Shanghai, Guangdong, Zhejiang, Jiangsu and other provinces and cities.
Analysis of Distributed Energy Investment Subjects
The main investment entities for distributed energy projects in China include: power generation groups, power grid companies, local city investment companies, and oil/gas companies.
1. Power Generation Group
The distributed energy research report shows that the domestic power generation groups engaged in distributed energy investment are mainly five major power generation groups in China, namely China Huaneng Group Corporation, China Datang Corporation, China Huadian Corporation, China Guodian Corporation, and China Power Investment Group. the company. Among them, Huadian Group is the first natural gas distributed energy project in China and has the largest number of development projects. At the same time, the company is also actively developing wind power, solar power generation, biomass power generation, small hydropower and other types of distributed energy. Huadian Group has obtained nearly one million kilowatts of distributed energy approved approval from dozens of provinces and regions such as Tianjin, Shanghai and Guangdong, accounting for two-thirds of the country's total.
2, the grid company
The power grid companies engaged in distributed energy projects in China are mainly two major power grid companies in China, namely State Grid Corporation of China and China Southern Power Grid Corporation Limited. Among them, there are 1052 distributed power projects run by the State Grid. In order to ensure the reliable grid-connected distributed power supply and the safe and stable operation of the power system after large-scale access, 16 enterprise standards, 8 industry standards and 8 items have been prepared. National standards have been devoted to solving the outstanding problems of the delayed construction of distributed power standards in China.
3, local city investment company
The local urban investment companies engaged in distributed energy projects in China are mainly distributed energy development companies that promote the development of local distributed energy and local urban construction investment companies. Such as Suzhou City Investment and Production Development Co., Ltd. launched a Suzhou Railway Station Complex Building Natural Gas Distributed Energy Station project.
4, oil/gas companies
Domestic oil and gas companies that participate in distributed energy projects mainly include CNOOC, PetroChina, and city gas companies such as Beijing Gas Group, Xin'ao Gas Company, and Hangzhou Gas Company. Among them, Beijing Gas Group has invested in and under construction of 4 distributed energy projects.
5. Other investors
Other domestic investment entities participating in distributed energy projects also include leading international energy groups, as well as domestic enterprises in other fields, such as Dalkia (China) Energy Management Co., Ltd., Schneider Electric (China) Investment Co., Ltd., Beijing Ennai. Special Distribution Energy Technology Co., Ltd., China Shipbuilding Industry, etc.
The prospect of distributed energy development
The Guiding Opinions on the Development of Distributed Natural Gas Sources pointed out that during the “Twelfth Five-Year Plan†period, China will build about 1,000 natural gas distributed energy projects, and plans to build about 10 typical distributed energy demonstration areas of various typical characteristics. By 2020, the use of distributed energy systems will be promoted in cities above designated size in China, with an installed capacity of 50 million kilowatts, which will initially realize the industrialization of distributed energy equipment.
The author believes that in addition to the national-level distributed energy policy, many provinces and cities in China have also introduced distributed energy-related policies to support the development of local distributed energy and provide financial support for the project. In addition, the completion and production of distributed energy projects in some provinces and cities in China provide rich operational experience for the development of distributed energy in other regions. Although at present, China's distributed energy resources still have obstacles and bottlenecks in grid connection, systems, financing, and technology, in the long run, China's distributed energy has a good prospect for development.
