Distributed power supply still faces institutional obstacles

<

Photovoltaic companies in China that have been clamped by the EU's "double opposition" have finally waited for good news. On July 15, the Chinese government website announced the "State Council issued several opinions on promoting the healthy development of the photovoltaic industry" (hereinafter referred to as "opinions"), proposing that the average annual installed capacity of new photovoltaic power generation will be around 10 GW from 2015 to 2015, by 2015. The total installed capacity reached 35GW or more - an increase of 70% in the installed capacity mentioned in the “Twelfth Five-Year Plan for Solar Power Development” issued by the National Energy Administration in 2012.

Encouraged by this favorable policy, on the 16th of July, there was an explosive rise in the solar panel market in the United States, and the PV counterattack appeared to have been on the road. However, the data show that by 2015, the subsidies needed for renewable energy in China still have a funding gap of more than 50 billion yuan. In the heat of photovoltaics, distributed generation projects are particularly eye-catching, and subsidized wars have been launched across the country.

Policy is good

As early as a month ago, the photovoltaic “National Six” was just born. At the State Council Executive Meeting in mid-June, Prime Minister Li Keqiang proposed to focus on expanding the application of distributed photovoltaic power generation. The power grid companies should ensure that the supporting power grid and photovoltaic power generation projects are synchronously built and put into production, with priority given to the photovoltaic power generation plan, and the full purchase of the generated power...

When the “National Six” was introduced, the industry cheered. “The implementation period of on-grid tariffs and subsidies is in principle 20 years, which at least gives us a confident expectation on the return on investment,” said a person in charge of the company's PV business unit in Jiangxi.

According to him, they are mainly engaged in photovoltaic modules and photovoltaic power station business. From the beginning of 2013 to now, due to the EU's "double reverse" case, the two projects destined for Turkey in 2012 were stagnant, and they can only send mail to them at the moment. Hope to open up the domestic market.

“With a subsidy expectation, photovoltaic power plant operators can even securitize assets to allow investment to advance and retreat, which can also share the risk of investment,” said the person in charge.

Unlike the “Golden Sun” project subsidy model, the “State of the Sixth” proposes the idea of ​​“subsidizing according to degree”. Meng Xianyu, deputy director of the China Renewable Energy Society, said in an interview with reporters that PV subsidy policy is expected to be introduced in August.

At the Shanghai PV Exhibition in mid-May, Wang Zhongying, deputy director of the Energy Research Institute of the National Development and Reform Commission, stated that the current discussion on distributed electricity prices is still under discussion. The proposal is that the electricity subsidies should be divided into three categories: subsidies for industrial and commercial users 0.2 Yuan/degree, 0.4 yuan/kWh for large industrial users, and 0.6 yuan/kWh for households, hospitals, schools, and rural residents who enjoy preferential electricity prices.

Photovoltaic Industry Association said that on the eve of the introduction of distributed power generation solutions, the final game is still on the pricing issue. "There is news that the subsidy price will increase from 0.35 yuan to 0.45 yuan."

In addition, in accordance with regulations, the new photovoltaic manufacturing project should meet the conversion efficiency of single crystal silicon photovoltaic cells is not less than 20%, polysilicon photovoltaic cell conversion efficiency of not less than 18%, but the current industry average single crystal battery conversion efficiency of about 18.8%, polysilicon About 17.3%. Some companies may be hard knocked out.

Distributed energy leap forward

The reporter noted that in a large number of policy supply, distributed energy projects have become a top priority.

The "Opinions" clearly stated that all the electricity generated by distributed photovoltaic power generation will be included in the total social power generation and electricity consumption statistics as an indicator for the performance evaluation of local governments and grid companies.

The “12th Five-Year Plan for Energy Development” issued by the State Council has for the first time devoted a section to vigorously developing distributed energy. It is required to build about 1,000 natural gas distributed energy projects by 2015, which means that distributed energy has become China. The key to energy strategy.

"Distributed energy is a form of energy development that combines multiple advantages such as energy saving, emission reduction, safety, and flexibility because of its proximity to users, utilization of cascades, high efficiency of primary energy use, environmental friendliness, and energy security and reliability." The person in charge of smart energy told reporters that at present, China is in an important period of rapid industrialization and urbanization, and energy demand is still facing rigid growth. "Simultaneous regional planning and distributed energy planning will make it possible to build more regional or large-scale distributed energy systems, and provide more favorable conditions for achieving energy system changes and energy-saving emission reduction targets."

Faced with the favorable prospects of distributed energy development, many domestic and foreign enterprises have already begun to test distributed energy in water, and new energy companies such as Xinao Group, Shuangliang Energy, China Huadian, and Schneider are committed to promote the construction of distributed energy. .

However, people in the industry pointed out that despite the fact that China's current energy use forms, distributed energy sources have been highly favored, there has been no "jump-forward" development.

Industry sources pointed out that distributed energy must be adapted to local conditions and integrate various factors to design a comprehensive industrialization program. The above-mentioned person in charge of the new Austrian further explained that from the perspective of the construction and application of distributed energy supply systems in China, most energy supply companies rely on single energy sources, and they will choose one of natural gas, solar energy, and wind energy to provide solutions for customers. The defects of the solution make the development of distributed energy limited by geographical, environmental, and cost constraints. More importantly, there are some technical problems that need to be solved in order to provide access to distributed energy for grid-connected, grid-connected, and distributed power sources. The difficulty of deployment between distributed supply and centralized power supply makes it difficult to compensate for the disadvantages of distributed energy instability.

At the beginning of July, the first national economic and technological development zone Ecological Park International Cooperation (EPIC) Joint Conference was held in Qingdao Economic and Technological Development Zone. The conference focused on the application of the Pan-Energy Network Technology in the Sino-German Ecological Park in Qingdao. It combines all kinds of energy and information flows to form an efficient energy utilization system. It not only addresses the instability of conventional distributed energy sources, but also proposes solutions based on multiple types of distributed energy stations. A package of energy solutions.

"Compared with traditional distributed energy systems, ubiquitous energy networks are capable of realizing intelligent dispatching with backbone networks such as national power grids, municipal gas and municipal thermal power, and synthesizing information networks, energy networks, and material networks into intelligent collaborative networks. The cascade utilization of energy, electricity, heat and other energy and intelligent synergy show a new model of energy utilization in the park, including energy clean production, supply and demand interaction, complementary peak shaving, efficient utilization, and energy conservation and emission reduction, thereby eliminating vertical shafts and corporate walls.” Austrian official said.

Subsidy system to be built

Even if it breaks through the know-how, distributed power supplies still face institutional barriers.

The biggest problem lies in subsidies. According to the disclosure of Zhao Yuwen, deputy director of the China Renewable Energy Society, in 2012, China's renewable energy fund had a special fund of about 10 billion yuan from the Ministry of Finance and an additional electricity price of about 20 billion yuan. Even according to the “Twelfth Five-Year Plan” target, the subsidy funds required for renewable energy in China by 2015 will be no less than 100 billion yuan, but with the current level of subsidies, there will be a shortfall of funds of more than 50 billion yuan.

However, seeing the opportunity of distributed generation, local governments have recently started the “price war” of distributed generation subsidies.

Take Tongxiang City as an example, the conditions for its opening are that Tongxiang City proposed to implement “one award double supplement” for demonstration projects with an installed capacity of 0.1 megawatts or more, that is, first to implement a one-off bonus of 1.5 yuan per watt for installed projects. Incentives; followed by government subsidies for photovoltaic power generation.

The highest subsidy price currently disclosed comes from Jiaxing Photovoltaic Industrial Park. The subsidy for individual distributed projects in the park will reach 2.8 yuan/kWh. The entire subsidy will last for three years, and will drop by 0.5 yuan year-on-year.

The introduction of this subsidy has been staggering. The park has signed a total of 12 projects with a total investment of 13 billion yuan, including 8 foreign-invested companies with a total investment of 320 million U.S. dollars, four domestic companies, and a total investment of 11 billion yuan.

The person in charge of the Jiaxing New Energy Technology Branch told the reporter that the expected increase in the number of projects affected by the distributed power generation project policy is very fast, and the return expectations are also optimistic. "The current cost is about 1MW 10 million yuan. According to the current on-grid tariff and subsidy policy, the cost can be recovered within 5 to 6 years."

“Under the current conditions, government departments need to further clarify the incentive mechanism, try to give preferential policies such as fiscal taxation for distributed energy projects, and use flexible market measures to motivate grid companies to actively participate in the development of distributed energy and related industries.” People conclude this way.
