Expected ROI of portable ESS system project in New Zealand 2026

What is ESS Energy Storage?

ESS systems provide resilient, sustainable energy storage well-suited for multiple use cases including utility-scale renewable energy installations, remote solar + storage microgrids, grid load-shifting and peak shaving, and other ancillary grid services. ESS technology is safe, non-toxic and has a 25-year lifespan without capacity fade.

What factors influence the ROI of a battery energy storage system?

Several key factors influence the ROI of a BESS. In order to assess the ROI of a battery energy storage system, we need to understand that there are two types of factors to keep in mind: internal factors that we can influence within the organization/business, and external factors that are beyond our control.

What factors affect the ROI of a Bess?

External Factors that influence the ROI of a BESS The cost of electricity, including peak and off-peak rates, significantly impacts the ROI. Energy storage systems can store cheaper off-peak energy for use during expensive peak periods.

When is the first Bess project commissioned in New Zealand?

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.
