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 Limited, a publicly-listed Australian company (ASX: RFX), produces small 10kWh zinc-bromine flow batteries that tolerate daily hard work in harsh conditions. Marketed as ZCell and ZBM2, Redflow batteries are designed for high cycle-rate, long time-base stationary energy storage applications in the residential, commercial & industrial and telecommunications sectors, and are scalable from a single battery installation through to grid-scale deployments. Redflow batteries are sold, installed and maintained by an international network of energy system integrators. Redflow’s smart, self-protecting batteries offer unique advantages including secure remote management, 100 per cent daily depth of discharge, tolerance of high ambient temperatures, a simple recycling path, no propensity for thermal runaway and sustained energy delivery throughout their operating life.
Redflow Limited (ASX:RFX) is pleased to announce an agreement with Mobax South Africa to provide batteries to test as a solution for mobile phone towers with a leading South African mobile network provider.
The agreement will see Redflow batteries deployed at existing mobile sites, with a particular focus on reducing the high cost of running diesel backup generators as well as being a less attractive target for theft. Redflow will supply as many as 10 ZBM2 batteries at its cost for the duration of the project, which aims to validate the technical and commercial benefits of the Redflow energy storage solution. The six-month project is expected to commence next month with defined success criteria that can be achieved earlier.
The ZBM2 batteries will be deployed and supported by Mobax South Africa, a new Redflow system integration partner. Mobax is part of Mobax Group, a leading field service provider of engineering, project and technical services to telecommunication network operators across southern Africa. Mobax Group, which has more than 350 field service engineers deployed across multiple countries, will be supported by Redflow’s long-time South African distributor SSS (Specialized Solar Systems).

Australian energy storage company Redflow Limited (ASX: RFX) has won a follow-up sale of 32 zinc-bromine flow batteries to provide standby energy storage for mobile phone towers in South Africa.
This second sale follows an initial order last month for five batteries for use at mobile phone towers run by a leading South African telecommunication company. The towers are owned by a local company that is supported by the South African Government’s Black Economic Empowerment (BEE) affirmative action agenda.
Redflow CEO Tim Harris, who received the new order after a visit to South Africa last week, said it clearly demonstrated the technological and commercial viability of Redflow’s zinc-bromine flow batteries for telecommunication deployments. “Our batteries thrive on heat and hard work, which is what these sites in South Africa require. Following yesterday’s Optus announcement, today’s new sale further highlights the value proposition that Redflow’s ZBM2 zinc-bromine flow batteries deliver to telecommunications companies, both in Australia and overseas,” he said.
Redflow today has announced an order to provide six ZBM2 zinc-bromine flow batteries for energy storage at an Optus mobile phone tower in the environmentally sensitive Daintree rainforest.
The Redflow ZBM2 batteries will store and supply 60 kilowatt-hours (kWh) of energy for the Optus mobile phone tower at Alexandra Range, in the Cape Tribulation section of the Daintree rainforest, a remote headland and ecotourism destination in Far North Queensland. Situated 1500km north of Brisbane, the Daintree National Park became a World Heritage Site in 1988.
Optus selected Redflow’s ZBM2 batteries for deployment at their Cape Tribulation site because of the batteries’ sustained energy storage capacity, tolerance of warm temperatures, remote management capability and environmentally-friendly design.

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.
