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.

Australia’s Chief Scientist visits Redflow battery-powered early childhood centre at Knox City Council

Australia’s Chief Scientist Dr Alan Finkel recently visited the Knox City Council’s state-of-the-art Children and Family Centre at Wantirna South in Melbourne to learn about the adoption and operation of Redflow zinc-bromine flow batteries which provide energy to the Centre.

Knox City Council has built two state-of-the-art early years facilities in Melbourne’s outer east – one at Wantirna South and the other at Bayswater – designed to last for 100 years, with leading-edge insulation, power conservation and renewable energy systems. 

Each Knox Children and Family Centre contains 18 Redflow ZBM2 zinc-bromine flow batteries – capable of storing 180 kilowatt-hours (kWh) of energy at each site – to ensure its renewably-sourced energy is available around the clock. Combined with 100 kilowatts peak (kWp) of solar panels on the roof of each building, Knox City Council expects this renewable energy system will save hundreds of thousands of dollars a year in energy costs.

Redflow batteries to star in Renewable Energy Pop-up in Brisbane this week

Redflow will display its breakthrough zinc-bromine flow battery technology at a Queensland Government-organised pop-up renewable energy event in central Brisbane this Thursday.

Queensland-based Redflow has developed world-leading energy storage technology by designing batteries that can deliver 100 per cent of their stored energy every day for 10 years without losing their storage capacity. Redflow batteries, which operate in warm climates without problems, are made from components that are easily recycled or reused at the end of the battery’s life.

The State Government-organised Renewable Energy Pop-up will run from 8am-6pm this Thursday, November 14, 2019, at  King George Square, Brisbane’s premier public square located in front of Brisbane City Hall in the CBD.

New Redflow partner predicts battery boom as WA solar tariffs end

West Australians are increasingly seeking the benefits of new-generation batteries as the State’s generous solar feed-in tariffs start to disappear, reports Redflow’s new WA partner Leith Elsegood.

WA homes that installed solar systems a decade ago are already losing the 40-cents per kilowatt-hour (KWh) feed-in tariff, introduced by the State Government to encourage the installation of solar panels. The 10-year feed-in tariff will end in 2021.

Since 1989, Mr Elsegood’s company, TIEC Services, has installed solar photovoltaic (PV) systems and energy storage systems throughout WA, at remote communities and, more recently, in high-end homes in the Perth metropolitan suburbs.

TIEC Services recently signed up as installer of new-generation Redflow energy storage batteries for Perth and WA. Already, the company has won large, residential solar and energy storage contracts with Redflow’s ZBM2 batteries. “The Redflow battery is ideal for WA conditions, handling the dry heat and the great distances in remote regions,” Mr Elsegood said.

Redflow receives order for ZBM2 batteries to power rural microgrid in North West Tasmania

Redflow Limited (ASX: RFX) has secured an order to immediately supply 27 of its ZBM2 zinc-bromine flow batteries for a Tasmanian farm owned by Simon Hackett.

Mr Hackett – Redflow’s largest single shareholder – has designed an energy system to deliver energy independence for the 73-hectare property, The Vale (http://www.thevale.com.au), located in North West Tasmania.

The Vale runs sheep and beef cattle, with ‘The Vale Lamb’ featuring on the menus of multiple hotels along the north-west Tasmanian coast. The farm, which is diversifying into additional forms of agriculture, is also exploring an expansion into eco-tourism operations. The energy harvesting, storage and distribution system at The Vale will use an initial deployment of 27 ZBM2 batteries, storing as much as 270 kilowatt-hours (kWh) of energy, interfaced to a large fault-tolerant cluster of 12 x Victron Quattro 48/15000 inverter/chargers. The system will harvest renewable energy from a 100-kilowatt peak (kWp) ground-mounted array of photovoltaic (PV) solar panels, with scope for future expansion.

Mr Hackett said his goal for the system was to create energy independence for the farm, delivering energy to power both building loads and electric vehicles. “The project, with an overall budget of around $1m, will include the building of a new site-wide microgrid. This will use new underground power interconnects to link seven distinct buildings across the whole property,” he said.
