Tianneng Power's stock surged 13.59% during intraday trading on Monday, reflecting strong market momentum for the company.

The rally was primarily driven by a broad-based surge across the power battery and energy storage sector, with improving sentiment around long-term energy storage demand. Research highlighted that rapid global renewable energy capacity expansion is increasing grid instability, which is expected to sustain rising demand for energy storage.

Additionally, the market appears to be digesting the company's recent short-term earnings headwinds and repricing the stock toward the sector's medium-to-long-term growth outlook, following a previous decline after disappointing quarterly results.
