Why Install a Home Battery in Double Bay?
The 17c/kWh gap between peak and off-peak electricity rates in NSW means a home battery can save you money by charging cheap and discharging when rates are expensive. A 10 kWh battery cycling once daily at 80% depth of discharge can save approximately $496 per year on electricity alone.
Virtual power plant (VPP) programs pay you to export stored energy during peak demand events, adding another revenue stream on top of bill savings. NSW's Peak Demand Reduction Scheme (PDRS) provides ongoing certificates for battery systems that reduce peak demand, worth $200 to $400 per year.
The median household income in Double Bay is $160,004 per year. With annual savings of $496 on a 10 kWh system, a battery is a practical investment for households looking to take control of their energy costs.
