Tesla selected as battery energy storage system supplier, the first Megapack 2 XL project in New Zealand. The project will be operational by March 2026. Wireless power, or inductive power transfer (IPT), is used in small electronics, manufacturing, transport, and medical. store energy on a large scale. However, until now we have had limited options to store electricity cost-effecti ly, close to where it is used. It can also store local sources of generation, such as rooftop solar, and smooth out the impacts that variable generatio can have on the power system. The Authority is expecting a significant increase in the amount of BESSs connecting to New Zealand's power system over the coming years and decades, especially as the cost of BESSs continues to fall. Summary: Auckland's energy storage.
