As New Zealand seeks to decarbonise its electricity system, dry year risk management will remain a key problem to solve, even as balancing wind & solar variability will grow in importance as an additional flexibility challenge.

A new study by Concept Consulting assesses the benefit that a flexibly operated green hydrogen facility could provide towards solving New Zealand’s dry year, and wind & solar flexibility challenges.

The study tests flexible hydrogen production against a number of other scenarios. These are retaining the Huntly coal reserve plant, retaining a small number of thermal peakers, overbuilding renewable generation and pumped hydro in the South Island.
