Intermittent Generation Does Not Increase NZ Electricity Price Volatility
Summary
The New Zealand Electricity Authority (EA) has published research findings showing that intermittent generation does not increase five-minute price volatility in the national electricity market. The analysis examined five-minute spot price data from 2021–2024, comparing periods of high intermittent generation against the full dataset and finding no evidence of elevated price swings. The EA concluded that other factors such as demand variability and unexpected plant outages are more significant drivers of price volatility than intermittent generation levels.

What changed
The EA published analytical findings on five-minute price volatility and intermittent generation in the New Zealand electricity market, covering the period 2021–2024. The research found no evidence that periods with higher levels of intermittent generation correlate with greater price volatility compared to the broader dataset. Energy companies and policymakers advocating for renewable energy investment can reference this evidence to counter concerns that variable renewable generation destabilises spot prices. Consumers and retailers may benefit from this finding as it suggests that increasing renewable penetration in the generation mix does not inherently increase price risk at the five-minute settlement interval.
