The price Meridian received for its generation fell sharply versus last year, but so did the cost to supply customers—down 47.3%, supporting margins. Customer connection numbers slipped slightly in July (down 0.2%), but are up 10.5% year on year.
Quarterly wholesale electricity futures for 2027-2029 continued to soften, falling more than 20% since February due to new generation projects coming online.
What's next for Meridian Energy?
Looking ahead, Meridian highlights its strong renewable energy position and resilient storage levels as key strengths in meeting ongoing high demand. Continued development in wind, hydro and battery storage are set to help the company manage volatility and support the New Zealand grid.
Management will be watching market pricing closely while maintaining a focus on efficiency and renewable investment. Investors can access weekly storage updates on the Meridian website.
