Shanghai: PV grid-connected application lead users

Judging from the country's successive introduction of photovoltaic policies in 2012, distribution will become an important direction for photovoltaic applications. Therefore, the need to improve the current photovoltaic grid-connected environment is becoming more urgent. On October 26, 2012, the State Grid Corporation of China issued the "Opinions on Doing a Good Job of Distributed Photovoltaic Power Grid-connected Services (Interim)" (hereinafter referred to as the "Grid-connected Services Opinions"), and solemnly promised to the public that since 2012 From November 1st of this year, free access to 6 MW, 10 kV photovoltaic power generation projects, the relevant applications for power grid approval will be completed within 45 days. Since then, the grid-connected problems that plagued domestic PV development have been able to break ice.

The timely issuance of "Views on Grid Services" is not only a major benefit to the development of the new energy industry, but it is also generally considered by the industry to be the best embodiment of the social value of the State Grid Corporation. Today, the “Grided Service Opinions” has been issued more than two months ago. In order to understand the photovoltaic grid integration situation and problems encountered in various provinces across the country, this reporter set off from Beijing and visited Shanghai, Zhejiang, Shandong, and Tianjin successively. Photovoltaic grid-connected provinces and cities with more active development launched a series of reports and shared with readers the specific actions of distributed photovoltaic grid integration.

Judging from the lighting resources, the annual average solar radiation in Shanghai is 4500 MJ/m2, which belongs to the three categories of solar radiation and has the basis for the development of solar energy applications. According to the statistics of the State Grid 95598 customer service hotline, as of now, Shanghai has received more than 60 consultations on distributed photovoltaic power generation projects, and officially accepted 11 applications for distributed photovoltaic power generation projects, including 4 residential users. In 7 cases, the user has become the city with the most users connected to the network at the current stage.

Project declaration only needs two chapters

A few days ago, a reporter from China Energy News visited the Shanghai Pudong Power Supply Company Pu Circuit Business Office, which has the largest number of PV power station projects in Shanghai. Wu Zhiwei, manager of the business hall, briefed the reporter: “At present, the business hall has received on-site consultations from nine customers, including seven corporate customers and two residential customers. The three projects officially accepted by the business office are corporate customers. The two households accepted the application in early November 2012 and are now in the self-construction phase of the project; another has just submitted the application and the data is still in preparation; the two households mainly consulted relevant policies."

Compared with the past, after the State Grid Corporation of China issued the "Views on the Integration of Services," the industry's widely-reported complex declaration process and long reporting period have greatly improved. Wu Zhiwei said: "For enterprise customers, the application for grid connection only needs to cover two chapters. One is the 'Road' of the National Development and Reform Commission, and the other is a grid-connected feasible solution of the State Grid Corporation. The individual customer also refers to this process, but it is not necessary. Provide the 'Roads' of the NDRC, but provide permission to the neighbors of the grid company or the property company."

"So far, no one has applied to go through the whole process." Wu Zhiwei said, "The main reason is that the self-built PV power stations of the two users have not yet been completed. The other one is due to the fact that the National Development and Reform Commission has not yet obtained the road. 'We, according to the requirements of the headquarters of the State Grid Corporation of China, conducted a 'first acceptance, first plan' service, and after the user obtained the 'road', continue to follow the relevant procedures."

The photovoltaic power station project built on the roof of Century Seaview is one of the recently submitted applications. The project was put into operation at the end of December 2012. Zhang Jianyu, general manager of Guoxin Real Estate, said in an interview: “We are very satisfied with the service attitude of the State Grid, but if the State Grid Corporation can provide professional guidance to the owners at the beginning of the project design, it would be better.”

Special window dedicated policy

In Shanghai Pujie Circuit Business Hall, the reporter saw that there was a sign of “photovoltaic power plant project” at the obvious place in front of the counter No. 4. It indicated that this was a dedicated window for PV grid-connected applications. A staff member was patience. To answer customer inquiries. At the information office of the lobby of the business hall, the reporter saw the publicity page of the “Notice on Distributed Photovoltaic Power Grid-connected Services”, and nearly half of them had been read by customers.

Yuan Jian, deputy director of the marketing department of Shanghai Electric Power Co., said in an interview: "In order to coordinate the implementation of the "Grid Service Idea" of the State Grid, the Shanghai Electric Power Company has completed two rounds of related personnel training, which has reached more than 60 people and was issued at the same time. A total of 6,000 PV grid-connected brochures were distributed to the community."

Yuan Jian introduced that since the press conference of the State Grid Corporation of China on October 26, 2012, the State Grid Corporation of China has specifically requested the local power company to implement grid-connected photovoltaics on a monthly basis in order to ensure the implementation of the "Grid-connected Services Opinions." The situation was reported to the headquarters and a series of implementation documents were issued to local power companies one after another. Such as the “Regulations on the Management of Distributed Generation Projects and Grid Services” and “The Typical Design on Distributed Access Generation” and other documents to ensure that local power companies have acceptance of PV project acceptance, plans, project implementation and project access. Follow. At the same time, in order to better adapt this opinion to the localization of Shanghai, Shanghai Electric Power Co., Ltd. compiled the "Detailed Rules for the Implementation of Grid-connected Services for Distributed Generation Projects of Shanghai Electric Power Co., Ltd." and "Interim Interconnection of User-side Grid Connection Technologies" in accordance with the requirements of the State Grid. The "Regulations" and "The Settlement Program for On-grid Electricity" and other documents are expected to be introduced quickly after the demonstration.

Electricity price subsidy attracts the most attention

During the interview, the reporter found that there are many specific issues to be solved for distributed photovoltaics that are being actively promoted by various parties.

As the first project for individual users in Shanghai, the 3.1 kilowatt roof photovoltaic power station project of Prof. Zhao Chunjiang, director of the Institute of Solar Energy Research at Shanghai Institute of Electric Power, has been connected to the grid for six years. After the “photovoltaic grid service opinion” was issued, the country The network company took the initiative to replace the bidirectional meter for Zhao Chunjiang. According to the data on the electricity meter, during the 6 years, Zhao Chunjiang’s rooftop power station accumulated 18,100 degrees of power. Whether or not he received any subsidies from the state regarding the green power project, Zhao Chunjiang said: “Now it is unclear whether subsidies are two-way. Buckle, or the model for future settlement, the state and the power grid have not given a statement yet."

In this regard, Yuan Zhen explained: “The price of electricity subsidies is the most common problem in the consultation, and some of the projects that have already enjoyed state subsidies, and the on-grid electricity prices are settled according to the local benchmark prices for desulphurization. According to the requirements of the State Grid’s headquarters, the relevant national policies have not yet been obtained. The project, the State Grid temporarily settled in accordance with the desulfurization price, wait for the introduction of the state subsidy electricity price, the implementation of the 'back to back, the make up for the principle of compensation' for the liquidation.

In the interview, the reporter found that another issue related to electricity prices also plagued individual customers, that is, according to the requirements of the SERC, the power company must ask the other party to issue value-added tax invoices when purchasing electricity, but apparently individuals do not have the ability to issue VAT. Qualification of invoices, how to solve this problem remains to be seen.

In addition, as for the 45-day completion deadline promised by the State Grid Corporation, Yuan Jian believes that the time is relatively tight, and puts high demands on the power companies. “If there is no access system involved, the grid can be completed in 45 days without other projects, but if the project needs a large number of external equipment for power grid reconstruction, even if the green channel is opened, the duration will be relatively tight. With the application process, the preparation and implementation of the project, and the upgrading and transformation of power grid equipment, it will be a test for the grid company in the future." said Yuan.
