Photovoltaic grid-connected do massive government subsidies in the electrical switch factory news reprint ( http://jiandq.com/product-42.html )
Grid support distributed grid-connected photovoltaic approach " boots " over the weekend finally landing. In October 26th, the national grid issued a formal " on distributed photovoltaic grid service work opinions " (hereinafter referred to as " opinion " ), from the beginning of November 1st, power grid enterprises for distributed photovoltaic power generation project owners to provide access system scheme, parallel testing, debugging and other services to the entire process, no charge. At the same time, a full acquisition of surplus power, free system standby charge.
To this, industry experts believe that this policy will accelerate the domestic PV market to start, but because current photovoltaic power generation cost is higher, the final scale can be big key depend on government subsidies, predicting home distributed PV market will be the first from the industrial park, enterprise workshop concentrated demonstration zone started.
According to the opinion, distributed photovoltaic generating means is located in the vicinity of the power user, local use, with 10000 kV and below voltage level access network, and a single point of total installed capacity not exceeding 6 MW photovoltaic power generation project.
"A line is only 5 to 8 megawatts of power, in accordance with international statistical standards, more than 6 MW is the great power. According to estimates, 6 MW range can cover all of the roof and the photovoltaic building integration project. " State grid company spokesman Zhang Zhengling explained at a press conference that.
Opinion the biggest highlights is the network of distributed PV will simplify procedures and provide a series of free service. For example, distributed photovoltaic system access scheme by the city or county power grid enterprise customer service center is responsible for, in 45 working days to realize parallel operation. The whole process of service are free of charge, but the project access to public power grid by grid portion of the bill, the user only need to invest their own solar photovoltaic power generation equipment and part of for private use a cable line input.
China Renewable Energy Society, vice-president Meng Xiangan to think, the above provisions will be distributed photovoltaic project owner to save cost, network access efficiency is greatly improved, the previous single system access scheme a project to pay ten yuan.
To this, the company deputy general manager Shu Yinbiao said, the State Grid several years ago to foresee the new energy revolution, made a lot of preparations, the future Chinese power system is fully capable of receiving large-scale renewable energy.
But, at present domestic photovoltaic power generation installed capacity is still relatively small. As of September, China State Grid Corp to operate the area of grid-connected photovoltaic power generation capacity of 2710000 kilowatts, an increase of 4.2 times. Power generation capacity of 2520000000 kwh, an increase of 5.4 times. Has agreed to grid-connected photovoltaic power generation project is the construction of 1260000 kw.
In addition, built in the internal user sites distributed photovoltaic power generation project generation can be entirely online, all are for personal use or spontaneous personal use while surfing the Internet, by the user to choose, the user is insufficient power by power grid enterprises provide, upper and lower electricity network separate settlement. This means that the future of distributed PV power generation project owners can sales to grid residual electricity.
The grid is very clear and high-profile stance on PV project support, no doubt to the troubled domestic photovoltaic enterprises bring some warmth, but for the domestic distributed photovoltaic application market start action has after all how old still depend on government subsidies.
" The current distributed photovoltaic power generation cost is still relatively high, need government subsidies, so that its future application of size or with government planning. " Zhang Zhengling when accepts " Economic Reference News " interview with reporters, in accordance with state regulations, State Grid to a yuan of electricity price of the acquisition of photovoltaic power generation, the Chinese net pay is the equivalent of coal-fired units online electrovalency portion, the remaining part is subsidized by the government. " From economic considerations, only to receive a government subsidy of the project are suitable to do. "
Meng Xiangan also thinks, at present our country dweller electrovalency is low, built the application of distributed PV is not effective, and the industrial and commercial electricity prices generally exceeded 1 yuan, use distributed photovoltaic system has certain economic, domestic distributed PV market will likely from industrial park, factory, enterprise economic Park concentrated demonstration zone started.
Reportedly, a MW photovoltaic power plant covers an area of about 4 acres, according to the current ground power 1 watt investment of about 10 yuan of computation, 1 MW of about 10000000 yuan of investment. For ordinary residents investment is too large, but for electricity demand larger enterprises, industrial parks, according to the maximum of 6 MW calculation, namely the investment of 60000000 is not much, if the local effective duration of sunshine is enough, 1 years to reach 1500 hours is profitable.
Recently the National Energy Bureau disclosed " solar power development " Twelfth Five-Year Plan " " shows, to the end of 2015, solar power installed capacity target of 21000000 kilowatts and above, which in the distributed power generation project for 10000000 kw.
" National power grid the provisions and requirements will facilitate our distributed PV rapid development, but this rule or principle, not perfect system. " The National Energy Bureau of new energy department vice director Shi Lishan said, the Bureau of energy are also being developed for " promoting distributed photovoltaic application management approach ".
