- Location: Wantirna South and Bayswater in Knox City, Melbourne, Australia
- 36 x ZBM2 batteries, storing 360 kilowatt-hours (kWh) of energy (18 at each site)
- Inverter: 12 x 15 kilovolt-ampere (kVA) Victron Quattro inverter-chargers (six at each site)
When Knox City Council in Melbourne’s outer east built two state-of-the-art early years facilities in 2018, it designed them to last for 100 years, with leading-edge insulation, power conservation and renewable energy systems that can save hundreds of thousands of dollars a year in energy costs. As well as 100 kilowatts peak (kWp) of solar panels on the roof of each building, the Knox Children and Family Centres at Wantirna South and Bayswater each contain 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. 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 an estimated $220,000-$240,000 in total annual savings.
