According to the director of the street lighting business of Shuangliu County Urban Management Bureau, the entire project adopts the EMC model. The cost of the project is 4 million yuan, all of which are borne by the transformation enterprise itself, and the daily maintenance costs are also the responsibility of the enterprise. According to the calculation of this section, the annual electricity cost can be saved by 480,000 yuan after the renovation. The saved electricity costs are invested by the payment company. 
On May 24, the street lighting renovation project of Chengdu Airport Road Shuangliu Section was officially completed. 4,800 ç› fluorescent lamps were replaced with 640 ç› LED street lights, the brightness was more than doubled after the renovation, and the road section saved 560,000 kWh of electricity every year.
