Photovoltaic grid-connected quick service detonates roof business opportunities

From application to grid-connected power generation, the Haining Leather City rooftop distributed photovoltaic power generation project took only 35 days, including Saturday and Sunday, and completed distributed photovoltaic grid-connected work for 45 days than the State Grid Corporation promised, 10 days in advance.

Such rapid grid-connected is Yao Yi, special assistant to the president of Tiantong Hi-tech Group Co., Ltd., who did not anticipate it. Just two months ago, he was still stuck in the difficult and slow progress of the project.

If you do not see it with your own eyes, it is hard to imagine that in Haining Leather City, the largest and most influential leather market roof in China, there are 15358 photovoltaic modules quietly standing. After grid-connected power generation, its “silence” can save Haining Leather City about 2.5 million yuan in electricity costs each year. What's more valuable is saving 1492 tons of standard coal, reducing 3718 tons of carbon dioxide emissions, and reducing 112 tons of dioxide* emissions.

However, for investors Tiantong, these benefits seem to have nothing to do with it. There seems to be more attractive business opportunities behind this grid-connected distributed photovoltaic power generation project.

Bringing Win-Win Roof Resources On December 20th, 2012 in Haining, Zhejiang, the gloomy sky and pudg rains shrouded the city known as the “Leather Capital of China”.

Even in such weather, before midday, there were still more than 900 kilowatt-hours of electricity, which was sent out from the distributed photovoltaic power generation project in Leather City, and was brought into the grid on the side of Leather City, and was eventually consumed entirely by the inside of Leather City. According to reports, in fine weather conditions, the power generation can easily exceed 10,000 kWh.

This photovoltaic power generation system, which covers 46,000 square meters of roof area, has an installed capacity of 3.6 megawatts. In 2011, Tiantong Company reached an agreement with Haining China Leather City Co., Ltd. in the contract energy management mode to acquire the power to build distributed photovoltaic power generation projects on the roof of the Leather City, and successfully applied for the Golden Sun demonstration project that year. In 2012, the project construction started.

According to the agreement, on the basis of the commercial electricity price of Leather City, Leather City will enjoy certain discounts when using Tiantong Photovoltaic Power Generation Project. If the price of electricity is raised, the rising income will be divided in proportion. The project is designed to generate about 3.5 million kilowatt-hours of electricity annually, accounting for one-tenth of the 36 million kilowatt-hours of electricity used in Leather City.

In fact, even a dime discount can save a huge amount for Leather City. However, all this has a necessary precondition – on-grid.

After the completion of the project in July last year, Yao Yue began to prepare related grid connection issues and submitted an application to the Haining Power Supply Bureau. However, when the new grid-connected government policy was not yet introduced, there was a policy gap in low-voltage power-side access. If you choose to connect from the 10 kV voltage side, it means that Yao Yue had to increase the investment by millions, and at the same time bring about the loss of electrical energy. And trouble.

Hu Zhou, deputy director of the Haining Power Supply Bureau, has been repeatedly communicating with Yao Yao on the network. On October 26, 2012, when the State Grid Corporation of China introduced the “New Deal” for distributed photovoltaic grid-connected services, Hu Zhou immediately relayed the information to Yao Yao. Immediately, the Haining Leather City roof photovoltaic project applied for “spontaneous use and excess power access. "The grid connection application form was also submitted to the Haining Power Supply Bureau.

Accepted, technical support, site acceptance, and network access, one-stop rapid access to network services so Yao Yao some "flattered." But for him, once the project is connected to the internet one day earlier, it can be profitable one day earlier.

In the more than one month after the New Deal, there were three companies with a total capacity of 31.2 megawatts, and submitted a grid-connected application for the distributed photovoltaic power generation project to the Haining Power Supply Bureau.

“Looking at this situation, the roof will become a scarce resource like land, and its renting price will surely be pushed up. With the introduction of the new grid-connected government, the rooftop distributed photovoltaic project will be hot, and it is very difficult for our company to invest in projects. Big, but it is a way to provide services to companies that are interested in investing in distributed photovoltaic power generation projects. Yao Yao has already seen business opportunities.

Tiantong Company, which mainly manufactures upstream products and equipment such as battery modules, has gradually found a new path for the development of photovoltaic companies.
