Redflow batteries have stored and supplied more than 50 MWh (megawatt-hours) of renewable energy for a Vodafone NZ telecommunications tower in a remote part of New Zealand’s North Island.
Vodafone New Zealand has met the challenge of bringing broadband connectivity to the remote Kauaeranga Valley, where no grid power is available, by deploying a best-in-class green energy cell site, powered by Vertiv’s Hybrid Energy Storage System (HESS) with energy stored by Redflow batteries.
Located east of Thames, on the edge of the Coromandel Forest Park, the Vodafone tower site, which includes five Redflow ZBM2 zinc-bromine flow batteries, has improved mobile phone coverage and high-speed wireless broadband for thousands of locals and visitors in the region.
The Redflow batteries store renewably sourced energy from 12 kilowatt peak (kWp) of installed photovoltaic solar panels and two kilowatts (kW) of installed wind capacity. Since they were installed in 2016, the five ZBM2 zinc-bromine flow batteries, with a total energy storage capacity of 50 kilowatt-hours, have stored and supplied more than 50 MWh (megawatt-hours) of energy.
