Outdoor Container Battery Energy Storage System
Electrotest provides tailored Battery Energy Storage System (BESS) solutions in New Zealand. From design and integration to testing and
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.
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.
A BESS is a number of large batteries that operate together as an energy storage facility, and is a bidirectional user of an energy network - meaning that it is able to 'take' energy from the grid (to store), and it can discharge that energy back into the system when required.
Whilst amendments were first made to New Zealand's Electricity Industry Participation Code 2010 (the Code) in 2018 to facilitate grid-scale BESS, the first significant (35MW) BESS project was not commissioned until March 2024.
