Core Viewpoint - The city of Liaocheng is prioritizing electricity supply security during the summer peak season, emphasizing its importance for urban stability and residents' quality of life [1] Electricity Supply Situation - During the summer peak period, electricity supply is expected to be sufficient during the midday peak and slightly surplus during the evening peak, assuming no extreme weather occurs [3] - The electricity load is projected to reach new highs, with midday and evening peaks expected to hit 6.55 million kilowatts and 5.95 million kilowatts respectively, representing year-on-year increases of 12.3% and 11.4% [3] - The highest load occurred earlier than in previous years, attributed to higher temperatures and prolonged heat, with the load surpassing 5 million kilowatts in May and reaching 6.284 million kilowatts on July 5, an increase of 435,000 kilowatts from the previous year [3] Power Generation Overview - In the first half of the year, total electricity consumption reached 35.885 billion kilowatt-hours, a year-on-year increase of 4.16%, with residential electricity consumption at 2.543 billion kilowatt-hours, up 2.46% [4] - Total power generation was 31.877 billion kilowatt-hours, a 1.96% increase year-on-year, with renewable energy generation at 3.84 billion kilowatt-hours, up 11.19% [4] - Solar power generation accounted for 3.267 billion kilowatt-hours, reflecting a 13.71% increase, while wind power generation was 360 million kilowatt-hours, up 1.06% [4] Power Supply Capacity - Renewable energy capacity has grown, with total installed capacity reaching 5.502 million kilowatts, a 20.7% increase, which supports electricity supply during peak periods [5] - The completion of the ±800 kV ultra-high voltage direct current transmission line enhances the grid's ability to handle extreme weather and peak demand, providing up to 1.18 million kilowatts of load support [5] - Backup measures include peak power generation from local coal-fired plants and centralized use of new energy storage, capable of increasing output by 380,000 kilowatts [5] Power Supply Measures - The city has implemented comprehensive supervision of energy supply work, ensuring sufficient coal inventory and stable operation of power plants [6] - As of now, four direct supply power plants have coal inventories exceeding 1 million tons, with an average daily coal consumption allowing for over 28 days of supply [6] - Safety measures include the completion of inspections and maintenance of power facilities, with significant improvements in the operational status of equipment and a 41.80% reduction in the 10 kV distribution switch tripping rate [6]
