Meridian’s generation for November was 2.7% higher than the same month last year, mainly due to increased hydro output. Year-to-date generation is tracking 12.7% ahead of last year, and the average price received for generation in November rose 93.3% compared to November 2024.

Higher demand from New Zealand Aluminium Smelters Ltd (NZAS) also featured, with average load rising to 569MW from 451MW a year ago.

Investors can keep an eye on Meridian’s ability to maintain strong hydro inflows and storage as summer progresses, supporting both generation and retail sales. The company continues to benefit from rising electricity demand and expanded customer connections.

Ongoing investment in renewable energy and a focus on operational efficiency position Meridian well for future growth, though weather patterns and wholesale market dynamics will remain key factors to watch.
