Geothermal, Wind and Other Electricity Generation in New Zealand Industry Data and Analysis
Operators in the Geothermal, Wind and Other Electricity Generation industry have faced volatile trading conditions, but very beneficial pricing conditions over the past few years. Disruptions to hydroelectricity and natural gas power stations have caused supply issues, which have led to a sustained period of elevated prices on the wholesale market. Prices have not fallen below $100 per megawatt hour since 2018-19, peaking at an estimated $171 per megawatt hour in 2021-22. In the decade prior to 2018-19, the average annual price on the wholesale market was approximately $67 per megawatt hour. This significant price growth has underpinned a surge in profitability across the industry. High prices also allowed the industry to offset higher costs, as revenue growth outstripped cost increases, while profit margins were also rising. Despite healthy prices overall, disruptions to demand in 2019-20 and a sharp drop in wholesale prices in 2022-23 weighed on industry-wide performances. Overall, industry revenue is expected to increase at an annualised 2.2% over the five years through 2025-26, to $2.2 billion. This trend includes an anticipated fall of 5.2% in 2025-26, driven by a drop in wholesale electricity prices after surging growth the previous two years.
