Updated 27/01/2026: DCCEEW STC purchase shortfall
The DCCEEW stated ‘We aim to make purchases in a manner which minimises market impacts'. Unfortunately this has not occured with the shortfall of STC purchases for battery STCs now exceeding 10 million certificates (> $400 million) putting tremendous strain on cashflow for businesses involved in the Cheaper Home Battery Scheme.
