Vodafone uses Redflow batteries to store energy for remote telecom tower site in New Zealand

Zinc-bromine flow batteries from Redflow have stored and supplied more than 50 MWh (megawatt-hours) of renewable energy for a Vodafone telecommunications tower in New Zealand during the past three years.

Vodafone NZ’s Kauaeranga Valley tower site is located east of Thames by the Coromandel Forest Park in a remote part of New Zealand’s North Island, Sites such as the Kauaeranga Valley are so remote that it is unfeasible to lay or connect power cables. Alternative power sources, such as diesel generators, come with their own set of challenges including a second generator for redundancy, high maintenance costs and expensive and difficult diesel deliveries.

Vodafone New Zealand has met the challenge of bringing broadband connectivity to the remote site, 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. The site, which contains 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.
