A hydroelectric power station uses turbines to generate electricity

Typically a dam stores water in a reservoir, and water released from it flows through a turbine, spinning it, which in turn drives a generator to produce electricity.

Dry river bed safety

Meridian's hydro assets are located in some of the most scenic places in New Zealand, making them popular spots to visit.

At times, we’ll release water from our hydro assets. We’ll always update signage near our assets to let you know when we’re going to do this. If you’re camping or fishing in a dry river bed, you must remain vigilant and follow all instructions. If you see water appear, the most important thing to do is get out of the water and stay out.

If you want more information on our planned flow releases, you can call the Meridian Control Centre on 03 4350 928.
