NSW will knock money off a workplace battery. The published cut is a range. Your quote is a different number.
From 1 September 2026, NSW chips in when a business installs a battery. Think of it as a voucher on the installer’s invoice. We will not turn the government range into your payback.
Picture a grocery warehouse at 8pm. The roof went quiet hours ago. The fridges did not. A battery is a box that holds lunchtime sun for that night shift — the same reason a big AI computer hall buys storage. The computers do not sleep when the panels do.
For a NSW workplace, that box now sits on a published discount. NSW Energy says the cut is larger with new solar — about 30 to 40 percent — and smaller for battery-only, about 20 to 30 percent. Eligible size: 20 kWh to 30 MWh. In plain terms, bigger than a house pack, smaller than a power station. Houses and big computer halls are out.
Good: a buyer can point at a government page, not a rumour.
Bad: that percent is a range, not a line on your invoice. The same page says the actual cut moves with the installer, the site, travel, the pack, electrical upgrades, and admin. The voucher is paid by a paper market — energy companies buy that paper under the scheme. That market moves.
Ugly: NSW tells you to shop installers. This desk does not. A comparison site is not a design. Sites off the public grid are out. A battery switched on before 1 September 2026 is out. Canberra’s solar help can sit on the same job if you meet both rules. Still not a number we will invent for your meter.
The bigger cut wants new solar within 90 days of the battery. If you already have a roof, that extra solar is at least a quarter of the new battery’s size. Read that twice before someone sells you “battery-only at the solar-plus rate”.
