COMMERCIAL ENERGY SUPPORT / VERIFIED 1 SEPTEMBER 2026
Find the support path. Do not build the case around it.
Commercial energy support can be an upfront discount, a tradeable certificate, an efficiency activity or a future rule change. Nexen separates each mechanism before it enters the business case.

NSW Batteries for Businesses incentive
Available from 1 September 2026. This Peak Demand Reduction Scheme certificate activity is usually delivered to the customer as an upfront discount through a participating installer. NSW indicates approximately 30–40% for a qualifying battery installed with new or additional solar, and approximately 20–30% for battery-only projects; the final value is quote and certificate dependent.
