A dry year is a year when there is less solar and wind so alternatives to LNG are useless

According to NIWA data, a dry year is, by definition, sunnier than average with less cloud cover and rainfall, so solar generation is not reduced.

Wind effects vary by region rather than disappearing: the South Island tends to see less wind in a dry year, while the North Island tends to see stronger wind.

Battery storage also exists as an alternative to LNG for managing variability. Also, when solar and wind are generating the hydro can wind down and our hydro lakes become a battery as well.
