Comparisons on a temporal basis of offshore wind generation with demand, other renewables, and hydro inflows, particularly during dry periods, provide useful information and context on how offshore wind could be suitably integrated into New Zealand’s generation. This report aims to identify and quantify the benefits of offshore wind for New Zealand. More specifically, how it matches electricity demand, how it works alongside other renewables, whether it could form part of a solution to the dry-year problem, and how offshore wind will contribute to the security of electricity supply in New Zealand.
