Australian energy storage company Redflow Limited has shipped zinc-bromine flow batteries made at its new factory in Thailand to fulfil its largest-ever order for use in a digital television network in Fiji.
New Zealand-based telecommunications infrastructure specialist Hitech Solutions last year chose Redflow’s ZBM2 batteries to provide energy storage for Fiji’s new digital television network which it is deploying for the Fiji Government throughout the Pacific nation, including remote islands.
Hitech Solutions ordered US$1.2 million worth of Redflow ZBM2 batteries to store and supply renewable energy to power the Fijian digital TV network. The company, which has operated a five-battery trial site in Fiji during the past year, intends to scale up its deployment of solar panels and Redflow batteries during the next six months. Hitech will install from five to 60 ZBM2 batteries at more than 10 sites in Fiji, many of which are on hills with no access to the country’s electricity grid.
Unveiled in December last year, the digital TV network will provide Fijians, even in the most remote parts of the country, with access to eight free-to-air television channels through a set top box, plus an option for catch-up TV. Digital television will also provide a platform to telecast important messages to people in maritime zones and rural areas in times of disaster, such as cyclones.
Hitech Solutions selected Redflow’s zinc-bromine flow batteries for the challenging project because of their robustness, long life, safety, temperature tolerance and straightforward recycling process. Hitech saved 40 tonnes of battery weight by choosing Redflow batteries over lead-acid batteries - the typical choice for telecommunication network energy storage.
Hitech Solutions Chief Technology Officer Derek Gaeth said Redflow batteries offered many benefits for the Fijian deployment. “The primary need was for a robust design with a long service life,” he said.
Australian energy storage company Redflow Ltd last month began manufacturing complete zinc-bromine flow batteries at its new factory in Thailand, which it is now shipping to customers in Australia and internationally.
Redflow reports the factory now has the capacity to consistently produce as many as 90 ZBM2 batteries per month. The company will synchronise production volumes with customer demand.
Redflow CEO Tim Harris said manufacturing complete batteries from the factory marked an important milestone for the company. “This achievement is underpinned by our ongoing focus on ensuring the consistent supply of quality batteries from this new facility,” he said.
Global energy system specialist Victron Energy is expanding grid-connection approvals globally for its new MultiPlus-II battery inverter-charger, boosting the market for this robust unit that works both on and off-grid.
Victron will also use the standards-compliance and competitive pricing of the MultiPlus-II to pursue large deployments that involve major rollouts of standardised energy storage systems across many sites.
Victron Energy BV Managing Director Matthijs Vader said the MultiPlus-II would expand Victron’s reach globally. “The new technical design and standards compliance of the MultiPlus-II brings the familiar Victron Energy MultiPlus technology to a world market at an even more competitive price,” he said.
“The MultiPlus-II is ideal for grid-connected applications such as distributed Virtual Power Plant (VPP) deployments that can both supply energy for individual houses and, collectively, deliver energy to the grid in a coordinated manner. This is an emerging market need that Victron is looking to support globally.”
