Since May 2007, Bengbu City has carried out energy-saving renovation tests and tests on three sections of Lianfang East Road, Xueyuan Road and Fengshou Road. The effect is very obvious, which laid a foundation for the large-scale “zero investment†energy-saving renovation of street lamps in Handan City. Base
How obvious can the power saving effect be? The two-month test results of three sections of Lianfang East Road, Xueyuan Road and Fengshou Road in Bengbu City show that two of the three sections have a power saving rate of 34% and a section of 37%. Even if the calculation is based on conservative data with a power saving rate of 25%, the electricity bill for the street lamps in Handan City will save 3.4 million yuan per year.
"Not only that, after the power-saving renovation, the life of the lamps will be extended, and the maintenance costs of the lamps will be significantly reduced." Liu Zhongli, general manager of Hebei Chaomei Technology Co., Ltd., responsible for this energy-saving renovation project, said.
How did this obvious effect come from? The relevant technical personnel said that, like the most fuel-efficient operation of the car at economic speed, the luminaire also has an optimal radiant power consumption ratio. In the first half of the night, the electricity consumption is large, the voltage is low, and the power consumption in the middle of the night is increased. The lamp is not always working in the optimal state due to the change of the power load, resulting in large power consumption, low efficiency, and affecting the lamps. life. The energy-saving retrofit is to install intelligent control equipment for the luminaire. The equipment can automatically adjust according to the change of the electric load at any time to ensure the best working state of the luminaire, thereby achieving the purpose of energy saving.
"What we originally proposed to the Bengbu City Finance Bureau and the street lamp is the 'zero investment' transformation plan. The company will bear all the transformation costs. The electricity saving income in a certain period of time is mostly owned by us. The Finance Bureau and the street lamp do not have any Any risk. But after the test results came out, because the power saving effect is too obvious, the relevant government departments require joint investment and share the benefits." Liu Zhongli said in an interview on July 6.
As early as the beginning of 2005, the Fengfeng mining area of ​​the city cooperated with Hebei Chaomei Technology Co., Ltd. with the “Zero Investment†scheme, and carried out energy-saving renovation of the street lamps of 25 road sections, reducing the street lighting cost of the original 800,000 yuan per year to 60. More than 10,000 yuan, energy-saving benefits are very obvious. After learning the information, the main leaders of Bengbu City issued instructions to the City Finance Bureau and the Municipal Public Utilities Bureau to cooperate with the energy-saving service company to renovate the urban street lights.
With the “zero investment†plan to carry out energy-saving renovation of the street lamps in Fengfeng mining area, Hebei Chaomei Company obtained the right to collect 55% energy-saving income in 7 years. In the renovation of street lamps in the urban area of ​​Handan City, the relevant government departments plan to use the "contract energy management" method to carry out energy-saving renovation of the street lamps in the urban area of ​​Bengbu City. The investment of both parties is more than 60%, and the savings of electricity costs are divided into five parts. Four years later, the equipment was handed over to the Bengbu Public Utilities Bureau. The savings were all vested in the city's finances, and the formal contract is expected to be signed this week.
