New South Wales has launched an upfront discount scheme that slashes the installed cost of battery storage systems by up to 40 percent for businesses and apartment buildings, directly targeting the commercial and multi-residential sectors that have largely been left behind in Australia’s rooftop solar and storage boom. The program, administered through the state’s Peak Demand Reduction Scheme, provides certificates that installers can trade to lower the customer’s initial outlay, making on-site storage financially viable for a much broader range of property owners and operators.
Australia leads the world in rooftop solar penetration, yet battery adoption in the commercial and apartment sectors has remained stubbornly low. Split incentives between landlords and tenants, complex strata governance, and higher upfront capital requirements have created structural barriers that residential rebates do not address. By extending certificate-based discounts to these segments, NSW is attacking the economics of storage at the point where grid value is highest — commercial and high-density residential loads that coincide with evening peak demand.
The scheme also serves a broader system security objective. As coal-fired generation retires and renewable penetration deepens, the Australian Energy Market Operator has identified a growing need for flexible, dispatchable capacity located close to load centres. Distributed batteries in commercial buildings and apartment blocks can provide frequency response, voltage support, and peak shaving without the transmission upgrades required for utility-scale projects. The NSW government estimates the program could unlock hundreds of megawatts of behind-the-meter storage by 2030.
Industry response has been cautiously optimistic. Installers welcome the revenue certainty that certificate pricing provides, though some note that administrative complexity and certificate price volatility could dampen uptake. The scheme’s success will ultimately hinge on whether the discount is sufficient to overcome the non-financial hurdles — strata approvals, metering upgrades, and fire safety compliance — that have historically stalled projects in multi-tenanted buildings. If effective, the model offers a template for other jurisdictions grappling with the same adoption gap.
