The Asia-Pacific’s first grid-scale battery storage system was opened in Auckland today by the Minister for Energy and Resources Simon Bridges.
The Tesla powerpack at the Glen Innes substation in Auckland will have storage capacity of 1MW/2.3MWh, which will be able to power 450 homes for more than two hours.
The opening also represents a major shift in how Vector manages its electricity network.
Vector chief executive Simon Mackenzie said the storage system could help reduce peak demand and extend the life of the substation, deferring capital expenditure and providing supplementary power to the local area, without compromising reliability.
“By gauging trends such as household energy consumption, the effect of infill housing and the uptake of new energy systems, we can target growth areas and deer or avoid the significant investment required in a new substation,” he said.
“And when connection or consumption growth requires a conventional network upgrade, we can mobilise the batteries to other parts of the network where power demand is rising,” he said.
Vector is a multi-network infrastructure company delivering energy and communication services to more than one million homes and businesses across New Zealand. Part of the Vector group, it offers renewable energy solutions in Australia.
