Home battery boom cuts power prices

Archived — this story has rotated out of today’s deck. It is kept here in full.

The gist

Australia's home battery subsidy program installed over 500,000 batteries, slashing wholesale power prices roughly in half.
The boom cuts grid costs but raises concerns about installation quality and grid-sharing reluctance.

Background

Australia launched the Cheaper Home Batteries Program in July 2025, offering a 30% discount on residential battery systems connected to solar arrays. The goal was to utilize excess solar energy and reduce reliance on fossil fuels during peak evening demand. The program has been so successful that it has more than doubled home battery capacity this year, significantly lowering wholesale electricity prices.
