China News Service, Chongqing, February 18 (Peng Guowei, Liu Yuanping, Yang Hailong) On February 18, Chongqing's first "zero-carbon" power supply station - Chengkoumiaoba "light storage and charging" integrated power supply station was fully put into operation.
"In the past, we could only charge in the city, but now there are charging piles in the town, which is more convenient." Early in the morning, Peng Daolin, a citizen, drove his newly purchased electric car to the charging pile facilities provided by the power supply to experience clean energy. convenience.
"Where does the electricity here come from?"
"This set of 15 kW AC charging piles uses all the electricity from the rows of photovoltaic panels on the roof of the power supply station." The answer from the on-site staff surprised Peng Daolin.

The entire Miaoba Power Supply Station is divided into three floors, and reporters entered it to visit. The first floor is the monitoring system of the State Grid cloud platform, which is connected to the rooftop photovoltaic panels to update the power generation and online data in real time; on the second floor, there is a heating system independently developed by the State Grid Corporation ( cold) system, the heating (cooling) area is about 700 square meters; the energy storage device with a capacity of 5 kilowatts (3 hours) is installed on the third floor; up to the roof, a total of 560 square meters of photovoltaics with a total installed capacity of 151 kilowatts are installed here It is estimated that the annual power generation will exceed 150,000 kWh, which is equivalent to an annual reduction of about 50.6 tons of standard coal and 152 tons of carbon dioxide emissions compared with traditional thermal power.
"The 'zero-carbon' power supply station is a microcosm of the new power system created by State Grid Chongqing Electric Power with the characteristics of Yu Power and the State Grid Demonstration. According to the mode of 'self-generated and self-consumption, surplus power grid', it realizes green energy use in the office area and truly realizes carbon Zero emissions." The person in charge of the project said that in the next step, State Grid Chongqing Electric Power will continue to promote the green and low-carbon transformation of energy in Chongqing, help achieve the "dual carbon" goal, and boost the high-quality development of Chongqing and the "twin-city economy" in the Chengdu-Chongqing region.
