New Zealand battery and energy storage

Can New Zealand recharge EV batteries?

In a New Zealand first, Counties Energy is completing the life-cycle for used electric vehicle (EV) batteries by converting them into its Berm Battery energy storage system for recharging EVs.

How much does a battery cost in New Zealand?

The mean charging spot price was $123/MWh and the median was $132/MWh. As New Zealand electrifies, more grid-scale batteries will support the growing renewable energy supply. Meridian Energy is building a 100MW (200MWh) battery near Ruakākā in sunny Northland. This battery is expected to be commissioned in September 2024.

Can 'non-hydroelectric energy storage' be a viable option in New Zealand?

As mentioned above, while New Zealand boasts large hydropower capacity, dry years due to low snowmelt or rainfall can leave hydroelectric unavailable for long periods. A government-supported project, NZ Battery, will investigate the feasibility of “non-hydroelectric energy storage options”.

Can large-scale battery storage help balance New Zealand's grid?

Transmission system operator Transpower also published studies in 2017 that showed the potential value of large-scale battery storage for balancing New Zealand’s grid and in 2019 that showed the potential value of distributed storage.

Can batteries be offered as instantaneous reserves?

This will enable batteries to be offered into the wholesale market as instantaneous reserves. The amendments include new provisions that will enable owners of battery energy storage systems (battery ESS) to offer instantaneous reserve while a battery ESS is discharging.

What are grid-scale batteries & how can they benefit New Zealand?

Grid-scale batteries maximise the benefits of renewable energy and provide extra resilience during times of tight electricity supply. Additionally, these batteries, alongside more renewable generation, will help off-set the retirement of thermal generation and support New Zealand’s transition to a low-emissions economy.
