Retail electricity prices are surveyed quarterly by the Ministry of Economic Development, from where the data for this chart set is sourced.
It is presented in two components - the lines charges, and the electricity charges.
The MED review assumes a NZ consumer purchasing 8,000 kWh per annum, and all providers in the country are surveyed.
The electricity component is the retail average, based on market share.

NZ runs large thermal plants as base load 24/7.
Replacing these requires new base load to equivalent capacity. Yet there is simply no economic technology available to do this. Batteries as in South Australia provide minutes for a very small percentage of their load and cost over A$ 100 million.
Small modern nuclear is the only realistic solution if we are not prepared to use the cheapest battery there is - - namely a coal pile at Huntly.
