/ PROJECT OVERVIEW
Grid-Scale Dispatchable Energy
The Otahuhu BESS Project is a 200 MW / 400 MWh standalone battery energy storage system being developed on industrial-zoned land in South Auckland, with a direct grid connection into Transpower's Otahuhu substation. It is one of the largest BESS projects under development in New Zealand and is structured to deliver de-risked, contracted cashflows in its early years while retaining significant upside from the merchant market in the second half of its operating life.

Why Otahuhu
Otahuhu has been the most economically significant node in the New Zealand wholesale electricity market for as long as the market has existed. It sits at the convergence of major transmission paths into Auckland, the country's largest demand centre, and historically clears at some of the widest peak-to-trough spreads in the country. Any battery built here is positioned to extract a higher revenue stack — from both energy arbitrage and ancillary services — than the same battery built anywhere else in New Zealand.
The 8 Sparky Road site is industrial-zoned, has direct connectivity to the Otahuhu substation, and operates under a full Resource Consent that has been granted, is unappealed and is in force — removing a category of planning risk that affects most other BESS projects at this stage of development.
