The heat wave swept through the mountains and rivers of the north and south, and the outdoor air conditioning units roared in unison in the twilight. Thousands of miles away, the silver wire suddenly woke up - the Hubei unit lightly opened the gate, and the current flowed eastward along the ultra-high voltage, silently replenishing before the evening peak in Jiangsu. An invisible electricity market is providing coolness for thousands of households.

Large scale high temperature push up electrical load

Recently, China has experienced widespread and sustained high temperatures, with electricity consumption in various regions continuously rising, and the national electricity load breaking historical records three times. With the help of the national unified electricity market mechanism, cross provincial and cross regional electricity trading is carried out in an orderly manner, providing a solid guarantee for the stable supply of electricity in summer.

Inter provincial spot goods realize cross provincial power allocation

The State Grid Jiangsu Electric Power Dispatching Hall welcomes the peak electricity consumption in the evening, and the local area has completed an inter provincial spot transaction to purchase 130000 kilowatts of electricity from Hubei. Relying on the unified national electricity market, each province can carry out power purchase and sales in combination with supply and demand dynamics, and cooperate with cross provincial transmission channels to achieve flexible resource allocation. By quickly matching through the trading platform, Hubei power is delivered to Jiangsu power grid on time, alleviating the peak power supply pressure in the southern Jiangsu region.

Expanding the supply guarantee space in the electricity market

Li Jie, the person in charge of power regulation at State Grid Jiangsu, said that in the past, to cope with peak electricity consumption, we could only rely on provincial power plants and fixed external electricity, and there was insufficient regulation space. Nowadays, the inter provincial spot market is like a national electricity supermarket, which can flexibly adjust electricity resources. Since July 2026, Jiangsu has exceeded 120 million kilowatt hours of electricity through inter provincial spot purchases, fully ensuring stable regional electricity levels.Editor/Gong Ziwei
