Zhuzhou city 30 thousand street lamp turned LED total expenditure of about 156 million

Recently, the Zhuzhou municipal government executive meeting clearly, Zhuzhou will be 6 months to the city's 30 thousand street lamps for energy-saving transformation.

LED street lamp can save electricity 40% to 50%

Zhuzhou city existing street lamp 40050, including high pressure sodium lamp 30551, LED street lamp 5726, ordinary energy-saving lamps and other light source street lamp 3773. According to the transformation plan, the city's primary and secondary roads, squares, bridges and alleys in the 30 thousand high-pressure sodium lamps will be replaced by LED street light.

LED street lamp energy consumption is low, the electricity saving rate is higher than the high pressure sodium lamp 40% to 50%; the service life is as long as 10 years, is the high pressure sodium lamp is 5 times; the power factor is in between 0.96 to 0.99, does not have the loss.

The implementation of energy-saving 30 thousand high-pressure sodium lamp, the estimated annual electricity savings of 25 million 470 thousand kwh, converted into standard coal can save 10189 tons, reducing carbon emissions by 25396 tons, reducing sulfur dioxide emissions 764 tons, reducing emissions of 382 tons of nitrogen oxides.

Introduction of new EMC financing model

After preliminary estimates, the total cost of energy saving renovation project is about 156 million yuan. To this end, Zhuzhou city introduced a new financing model of energy management contract (EMC), which is the energy service company to invest in energy saving transformation, and then from the energy efficiency in proportion, the annual repayment of its investment. The model has the advantages of zero investment, zero risk.

Energy saving transformation, the annual consumption of street lamps will be 44 million 400 thousand kwh, down to the time of 18 million 930 thousand kwh. Compared with before the street lights are turned on, the annual electricity savings can be 23 million 80 thousand yuan, compared with the current energy saving operation mode, still can save more than $17 million per year. In the EMC mode, the savings of electricity can be paid to transform the project investment costs.
