Go all out to ensure the safe and stable supply of electricity

At present, it is a critical period of summer energy and electricity security, how about people's livelihoods and key electricity security? At present, the power operation is stable and orderly, in the first half of the year, with the economic recovery, coupled with the summer high temperature weather came early, the range of hot weather in some parts of the north, the rapid growth of electricity demand, the country's daily power generation and electricity load continued to rise. At present, the national daily dispatch power generation has reached three record highs, and the country's highest power load has reached two record highs.

High-voltage shore power successfully achieved "full coverage", Ningbo Zhoushan Port broke the "green power code" again"

On December 28, at berth 2 of Daxie Container Terminal in Zhoushan Port, Ningbo, the container ship "Tianxiuhe" berthed and connected the terminal shore power system to supply power to the ship. This indicates that the four major container port areas of Ningbo Zhoushan Port have achieved full coverage and full operation of high-voltage shore power. State Grid Ningbo Power Supply Company has built and put into operation 13 sets of high-voltage shore power systems in Ningbo Zhoushan Port, covering the four major container port areas of Beilun, Chuanshan, Meishan and Daxie, involving 24 berths with a total capacity of 55.4 MVA. The high-voltage shore power facilities built and put into operation by the company will supply 63 times in 2023, with a cumulative power supply of 1.457 million kWh.

The national power supply is guaranteed during the peak summer period.

The meteorological department predicts that the temperature in most parts of China this summer is higher than that in the same period of previous years, and the situation of ensuring power supply in summer is grim. On June 20, at a series of press conferences on the theme of "promoting high-quality development" held by the State Information Office, the State Energy Administration will further optimize load management measures and accurately refine their implementation, resolutely hold the bottom line of not switching off power cuts, and resolutely ensure the electricity needs of people's livelihood.

Steady and orderly promotion of new energy participation in the electricity market

[steadily and orderly promote the participation of new energy in the power market] on June 20, Li Chuangjun, director of the New Energy and Renewable Energy Department of the State Energy Administration, said at a news conference of the State Information Office that in order to better promote the development of new energy, we will actively promote the construction of the power in stock market and form a time-sharing price signal that reflects power supply and demand in a more timely manner.

Good news to push the power equipment sector up, agencies recommend focusing on these two main lines

Recently, the National Energy Administration released data on electricity consumption in September. From January to September, the total electricity consumption of the whole society 6863.7 billion kwh, up 5.6 percent year on year. In terms of industries, the electricity consumption of the primary industry 97.6 billion kWh, an increase of 11.3 percent over the same period last year; the electricity consumption of the secondary industry 4470.3 billion kWh, an increase of 5.5 percent over the same period last year; the electricity consumption of the tertiary industry 1254.6 billion kWh, an increase of 10.1 percent over the same period last year; and the domestic electricity consumption of urban and rural residents 1041.2 billion kWh, an increase of 0.5 percent over the same period last year.

Electric power service "zero distance" to keep the masses "vegetable basket"

China Energy News Network (Zhou Tingting) "It's getting hot recently. Our vegetables and fruits are easy to deteriorate when the temperature is high. The freezer must be on all the time and the power supply cannot be cut off. Thank you very much for ensuring the power consumption of our shops." On June 19, members of the "Yellow River Bank" volunteer service team of the urban power supply branch of Gansu Linxia Power Supply Company of the State Grid came to Linxia Fulin Farmers' Market to investigate the hidden dangers of merchants' electricity safety, protect the "vegetable basket" of the masses, and ensure the power supply for the normal operation of the market and residents' procurement.
