Emma Hewitt is among those to benefit from the battery scheme. A single parent who lives with her seven-year-old daughter south of Perth, she was progressively electrifying her home – solar panels, replacing a gas cooktop, leasing an electric car through her employer – when the subsidy was announced. It prompted her, a local government worker, to go for an interest-free loan to cover the rest of the cost of a 16kWh storage unit, which has allowed her to cut her reliance on the grid and save hundreds of dollars on her quarterly power bill.
“I don’t have huge amounts of savings but I can afford to pay things off out of my wages,” she says. “It has been something that I’ve wanted to do for a while, largely because I’m worried about the planet that my daughter will inherit and the incredible damage that burning fossil fuels does to that planet.”
Alison Reeve the energy and climate change programme director at the Grattan Institute think tank, says it neatly illustrates how the energy system has been rewritten, almost overnight. Under the new model, households are producers and players in the market, not just consumers. Older forms of generation are increasingly being squeezed out. And the advent of batteries with longer durations means past criticisms of solar energy – that the sun doesn’t shine at night – is being “blown out of the water”.
“It is a profound change in how you run an energy market. The message is that if you can make rooftop solar happen, you can make a number of other changes really easily. And storing energy just opens up so much more flexibility in the system,” she says. “We’ve just found a new way to do it.”
