Average BESS price per 1GW in New Zealand

How much does a Bess battery cost?

Factoring in these costs from the beginning ensures there are no unexpected expenses when the battery reaches the end of its useful life. To better understand BESS costs, it’s useful to look at the cost per kilowatt-hour (kWh) stored. As of recent data, the average cost of a BESS is approximately $400-$600 per kWh. Here’s a simple breakdown:

How much does Bess cost?

The cost of BESS has fallen significantly over the past decade, with more precipitous drops in recent years: This is nearly a 70% reduction in three years, owing to falling battery pack prices (now as low as $60-70/kWh in China), increased deployment, and improved efficiency.

Will Bess become a cog in New Zealand's energy landscape?

We expect that BESS will also become an increasingly important cog in New Zealand’s broader energy landscape and that we will see utility-scale solar projects incorporating batteries as a means of providing dispatchable generation during peak demand and enhancing grid stability.

What factors affect the cost of a Bess system?

Several factors can influence the cost of a BESS, including: Larger systems cost more, but they often provide better value per kWh due to economies of scale. For instance, utility-scale projects benefit from bulk purchasing and reduced per-unit costs compared to residential installations. Costs can vary depending on where the system is installed.

Why is Bess important in New Zealand?

The uptake of BESS in New Zealand is particularly important given that it can help to solve one of New Zealand’s biggest energy challenges – meeting peak demand. In recent years, there have been ongoing concerns as to the reliability of New Zealand’s energy supply following blackouts in 2021.

How much electricity does New Zealand need?

Zealand’s annual electricity needs – about 8,000 GWh.A fully charged small BESS in every home would provide a total of 4 GWh of distributed storage across New Zealand. However, this is roughly equivalent to only 0.7 per cent of the nominal controlled hydro energy stored in lake Taupō, a
