Technical FAQs 4

Why do New Zealand homes need battery storage?

In most New Zealand homes, a large proportion of the energy produced by solar panels is sent back to the grid because it's generated when it's not needed, i.e., the middle of the day. However, adding home battery storage to a new or existing solar power system allows you to store your unused energy.

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.

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.

How can containerised batteries help the transition to greener energy?

Renewable energy storage in containerised battery units is already playing a major role in our transition to greener energy. By ensuring that no energy generated by wind turbines, solar power or other eco-friendly means is lost, batteries help countries and organisations of all kinds to accelerate decarbonisation goals.
