Datang Power (00991.HK) experienced a significant surge of 5.21% during intraday trading on Wednesday, marking a notable upward movement for the power generation company.

The stock's rise is attributed to several factors, including the ongoing summer peak electricity demand theme which continues to gain momentum across the power sector. Additionally, market expectations of AH premium convergence are driving interest, as the company's H-shares trade at a substantial discount to its A-shares with a price ratio of approximately 0.35.

The broader power generation sector also showed positive momentum, with other major players like Huaneng Power and Huadian Power registering gains. This sector-wide warming, combined with rebound momentum following an extended correction period, contributed to Datang Power's strong performance during the trading session.
