The Yangtze River Delta has made energy conservation the highlight of increased investment. Recently, 500 million yuan of special funds for energy conservation and emission reduction used by Jiangsu Province to reward enterprises have been honored to various projects in various cities. The Zhejiang Provincial Government announced that in the next three years, the province will strive to invest more than 10 billion yuan in energy-saving technological transformation each year, and increase its energy-saving capacity by more than 3 million tons of standard coal per year. Jiangsu has also invested 37 billion yuan in energy conservation and emission reduction.
Expand domestic demand and ensure growth, and the development of the Yangtze River Delta energy-saving industry will be high.
Energy saving service is sitting south
Now energy-saving service companies are sitting south. Hou Linfeng, deputy general manager of Jiangsu Taicang Zhenhui Chemical Fiber Co., Ltd. introduced that he recently negotiated a frequency conversion project with an energy-saving enterprise in Nanjing. The other party requested that the advance payment be paid first, and the equipment was shipped to work. Yang Linfeng, general manager of Ningbo Yixincheng Electric Co., Ltd. said that the company's newly developed solar wind energy complementary lamps have been vying for underwriting by multiple distributors.
Li Yahong, assistant manager of the safety production department of Taicang Port GCL Power Plant, told the reporter that the renovation of the circulating water pump was made by the plant. The price of the first unit was 70,000 yuan, and the sixth unit rose to more than 200,000 yuan. Less than a year before and after. It is understood that in recent years, the annual energy-saving technology reform funds invested by the plant have reached 30 million yuan.
Recently, investment in energy conservation from the state to the local level has led to an increasing demand for energy-saving services, and the energy-saving industry is bound to enter a period of rapid development. Pan Jiancheng, deputy director of the China Economic Climate Monitoring Center, said that from 2004 to 2006, the growth rate of China's energy-saving service industry remained at around 40%, and the industry's output value increased from 1 billion yuan to 2 billion yuan. In 2007, the growth rate accelerated significantly, reaching 250%, and the industry scale also climbed to 7 billion yuan. According to preliminary estimates, the scale potential of this industry is about 450 billion yuan, and energy-saving services are promising.
Energy-saving plates fly against the wind
The Yangtze River Delta is the fastest growing region for energy conservation services in China. At present, there are more than 80 companies specializing in contract energy management in Shanghai, more than 60 energy-saving service agencies in Zhejiang, and more than 40 building energy-saving service agencies in Jiangsu.
Taicang Zhenhui Chemical Fiber Co., Ltd. tasted the sweetness of contract energy management. The company signed an agreement with Zhejiang Kewei Energy Saving Co., Ltd., and Kewei helped Zhenhui to transform three pumps. After the transformation, it saved 900,000 yuan in electricity costs. Zhenhui paid Covey service fees every year according to the agreement, and ended the contract four years later. The transformation of the equipment will be owned by Zhenhui.
The energy-saving industry in the Yangtze River Delta has been blooming everywhere. In Zhejiang Shangyu, there are more than 200 energy-saving lamps enterprises with annual sales of 7 billion yuan. The local area will also build a large electric light source in East China. The energy-saving city is often located in Huzhou, Jiaxing, Yuyao, Zhejiang, etc. New energy-saving building materials companies are springing up. In the first half of last year, the total production of 36 new wall materials enterprises in Yuyao was 347 million standard bricks, equivalent to saving 174 mu of land, saving energy of 45.11 million tons of standard coal, reducing emissions of 720 tons, and utilizing waste of 623,000 tons. Jiangsu's new energy industry continues to accelerate development. In addition to solar cells, the wind power equipment industry has initially formed a complete industrial chain, including 8 wind turbine complete sets of manufacturing enterprises and 5 blade manufacturing enterprises, including wind turbines, high-speed gearboxes, and rotary machines. The domestic market share of key components such as bearings and wind power transformers has reached 50%. In Jiangyin alone, last year, the wind energy equipment manufacturing industry could achieve sales of 3 billion yuan.
Financing and other problems to be solved
It is understood that the energy-saving service company is mainly small and medium-sized enterprises, the registered capital is between 1 million yuan and 15 million yuan, and often the investment of a single energy-saving project exceeds 1 million yuan. When the energy-saving company wins the project, all investment must be advanced in advance. The issue of financing difficulties has attracted attention. Many local governments in the Yangtze River Delta have introduced subsidy policies to encourage the development of contract energy management, such as the implementation of contract energy management projects, the cost of testing in the previous period, the one-time special subsidies granted by the government, and the subsidies for special funds. Calculate, for every 1 ton of standard coal saved, in principle, the government subsidizes a few yuan and so on.
Experts also suggest that energy-saving companies can also clench a fist, and within a certain range, several companies with independent energy-saving products will jointly invest in the establishment of a company that provides energy-saving technical services.
The construction of laws and regulations must be accelerated. Sun Daming, executive deputy director of the Green and Ecological Building Research Center of the Shanghai Branch of the China Academy of Building Research, said that the current large industrial energy consumers are being supervised, but the supervision of a large number of high-energy buildings is blank. In the Yangtze River Delta, despite the number of companies engaged in building energy consumption monitoring, providing energy-saving solutions, and implementing energy-saving renovations, there are often no orders. Why? The key is the lack of relevant assessment standards and systems for public building energy conservation, and the relevant units have no energy-saving pressure. On October 1, last year, the State's "Regulations on Energy Conservation in Public Institutions" and "Regulations on Energy Efficiency in Civil Buildings" were officially implemented. However, it is really effective to rely on local governments to issue corresponding implementation rules, and to have special personnel responsible for law enforcement supervision of building energy conservation.
