The Australian battery discount is paid in traded paper. Tuesday’s price is not your contract.

Small-scale technology certificates sit under the federal battery help. That paper trades. A screenshot is not a locked cheque.

A grain ticket is not a stamped refund. Australia’s small-scale scheme pays a discount by creating certificates. An installer often takes those certificates and knocks money off the invoice. The dollar in that knock is a market dollar.

The Clean Energy Regulator runs the scheme. Eligible small-scale batteries can create certificates. The government page for Cheaper Home Batteries says the support is delivered that way, and that the factor used to count certificates steps down over time. We will not print today’s traded price. It moves.

Good: the scheme is public. You can read who writes the rules.

Bad: “around 30 percent” on a government page is a target built on that paper, not a line your accountant can lock on Monday.

Ugly: anyone who nails your payback to yesterday’s certificate is guessing the market and guessing when your building uses power. Two guesses. No quote.

Ask what certificate value they put in the invoice, and on what day. Then treat it as a day, not a decade.
