Datang Power's stock surged 5.12% during intraday trading on Friday, marking a significant upward movement for the utility company.

The rally appears driven by the intensifying summer peak electricity demand theme, with Southern Power Grid's load recently hitting record highs nearly a month earlier than the typical seasonal pattern. National peak load this summer is projected to increase by approximately 90 million kilowatts year-over-year, supporting power sector fundamentals.

Additionally, market expectations of AH share premium convergence are contributing to the positive sentiment, as the company's H/A share ratio remains at approximately 0.35. The broader power sector also showed strength, with peers including Huaneng Power, Huadian Power, and China Resources Power posting gains during the session.
