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 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.”

While some projects experienced customer delays, we received initial orders from several important projects and are confident that orders will scale in FY20 as we receive follow up orders and expand our customer base.” Continue reading “Foundations in place to underpin Redflow’s growth”

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.

Knox children centres cut 75% of energy costs in winter with Redflow batteries

Two state-of-the-art children and family centres in Melbourne’s outer eastern suburbs have eliminated three-quarters of their energy costs during winter with insulation, solar panels and Redflow batteries.

The Knox Children and Family Centres at Wantirna South, which opened in January 2019, and Bayswater, which opened in March, each contain 100 kilowatts peak (kWp) of photovoltaic solar panels and 18 Redflow ZBM2 batteries, storing as much as 180 kilowatt-hours of energy. They also include innovative insulation and thermal sealing to retain heat in winter and cooling in summer.

The performance of the integrated solar panel and battery systems in their first months exceeded Council’s expectations, generating 75 per cent of the power requirements for both of the hubs during winter. The installation of the solar array and batteries is anticipated to save Council an estimated $110,000 – $120,000 per annum at each facility, delivering a total annual saving of $220,000-$240,000.
