en.Wedoany.com Reported - On April 16, electricity from multiple provinces including Gansu, Hubei, Hunan, Shaanxi, and Ningxia was "delivered" to the Guangdong-Hong Kong-Macao Greater Bay Area. The maximum daily transmission power reached 11 gigawatts, with a cumulative transaction volume of 16.79 gigawatt-hours, sufficient to meet the daily electricity demand of approximately 2 million ordinary households. This provided strong support for regional price stability and supply security through market-based mechanisms.

This transaction was carried out through the collaborative efforts of China Southern Power Grid and the State Grid, involving simultaneous cross-operational-area spot and medium-to-long-term electricity trading. It innovatively adopted the model of "medium-to-long-term contracts as the base, supplemented by spot trading," fully leveraging the resource optimization and allocation role of the national unified electricity market. This represents a significant practice in cross-regional joint power supply and mutual support.

Since April, the southern region of China has experienced an early and warmer-than-usual summer. Electricity load and consumption in Guangdong and Hainan within the China Southern Power Grid operational area have been continuously rising. Notably, Guangdong's peak power load exceeded 130 gigawatts, 15 days earlier than last year.

"Through the joint operation of the two major power grids, short-cycle spot trading flexibly supports peak demand, achieving optimal allocation of power resources nationwide," said He Shizhi, Senior Manager of the Spot Market Department at the China Southern Power Grid Dispatch and Control Center. To enhance power supply resilience this year, China Southern Power Grid, in collaboration with the State Grid, has been continuously improving the cross-grid operational area trading coordination mechanism and exploring market-based solutions.

It is reported that from April 15 to 16, the Guangzhou Power Exchange Center, jointly with the Beijing Power Exchange Center, successfully organized medium-to-long-term power trading from Hunan to Guangdong across grid operational areas. It is expected that from April 25 to 30, the Jiangcheng DC line will transmit power to Guangdong at full capacity, with a maximum daily transmission volume reaching 120 gigawatt-hours, precisely matching Guangdong's electricity demand.
