Why Install a Home Battery in Hmas Watson?

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 Hmas Watson is $181,012 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.
