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.

Redflow to deliver ZBM2 batteries for telco mobile phone tower sites in South Africa

Australian energy storage company Redflow Limited (ASX: RFX) has won an order to provide 68 ZBM2 zinc-bromine flow batteries for at least 20 mobile phone tower sites in South Africa owned by one of Africa’s leading telecommunication companies.

The company, which provides telecommunication services to millions of customers across a number of African countries, decided to deploy Redflow batteries in its infrastructure after successfully testing ZBM2 batteries in a proof of concept trial. Deployment is scheduled to begin this month. Redflow expects to receive revenue from the order this calendar year, which has a commercial gross margin.

This latest sale extends the presence of Redflow batteries in South Africa after last year’s announcement that it had sold 32 zinc-bromine flow batteries to provide standby energy storage for remotely-located mobile phone towers in South Africa.

This new order for ZBM2 batteries is through Redflow’s South African partner Mobax, which will be responsible for the installation and on-going support of the batteries under its field services agreement with the mobile phone company. Redflow’s long-time South African distributor and solar integrator, Specialized Solar Solutions, will provide first-level in-country support to Mobax.

Mobax will commence deployment of Redflow batteries at mobile base stations that are currently powered by diesel generators. The ZBM2 batteries will reduce operational costs through less diesel use, lower fuel delivery costs to remote locations and less frequent generator servicing.

Using Redflow batteries to reduce diesel use will also lower carbon tax liabilities arising from South Africa’s new carbon pollution reduction regulations, which came into force on June 1 this year.

Mobax Chief Operating Officer Maris Van Wyk said Mobax was delighted to extend its partnership with Redflow through wider deployment of the company’s innovative zinc-bromine flow battery technology in South Africa’s telecommunications market. “As well as delivering substantial opex (operational expenditure) savings, the ZBM2 battery offers many benefits in the South African environment including its long operating life and temperature resilience,” he said.

“We are also confident that the ZBM2 battery, which weighs about 240 kg and has no secondary resale value, will be less prone to theft than conventional batteries. These are challenges faced by other telecommunications companies throughout Africa, so we see this as a significant opportunity.”

Redflow Managing Director and CEO Tim Harris said this latest South African order demonstrated the value that zinc-bromine flow batteries offered to the telecommunications sector internationally. “Energy storage for mobile phone towers is a well-established market globally,” he said.

“To date, it has faced high operating costs through the use of diesel generators and three-year replacement cycles for lead-acid batteries – or more frequently if these batteries are stolen for their recycling value. With a 10-year warranty and theft-resistant features, our ZBM2 zinc-bromine flow batteries solve these problems, delivering long-life, hard-working energy storage in warm climatic conditions.

“This latest order demonstrates Redflow’s progress towards supplying this market opportunity.”

Redflow supplies batteries for South African mobile phone towers

Redflow Limited has received an order to supply five zinc-bromine flow batteries for a pilot project to provide standby energy storage for mobile phone towers in South Africa.

This order will see Redflow provide the project with batteries for five identified sites with the first batteries to be deployed in November. The project will see Redflow’s zinc-bromine flow batteries provide energy storage for the mobile phone towers, operated by one of South Africa’s leading telcos. The towers will be owned by a local company, supported by the South African Government’s Black Economic Empowerment (BEE) affirmative action agenda.

The sale was made through Redflow’s long-term South African partner, Specialized Solar Systems (SSS), which has formed a joint venture company with specialist telco supplier Amber Energy. Called SSS Gauteng, the new company will deliver the energy storage and telecommunications skills to deploy the batteries on remote mobile phone towers.

Redflow has worked with SSS to enable its batteries to operate in Standby Power System (SPS) mode. In this newly created operating mode, Redflow batteries can be charged and then placed in a dormant state, with no self-discharge, until a power outage. When energy is required, the battery can boot up to full operational status in a similar timeframe to a standby generator – with no internal combustion engine and no fuel storage required on the site.

Redflow Managing Director and CEO Tim Harris said this sale created a significant opportunity for the company. “The Standby Power System, which Redflow has developed with our partners, will help open the door for access to other cellphone network operators in Africa and internationally,” he said.
