In Townsville, Ergon Energy has already begun trials of solar battery combinations with 10 of its customers, and has begun rolling out a program of localised grids powered with major battery units into 12 remote communities across Northern Queensland.
Barry and Glenys Lowe’s house is part of the Townsville trial, and they are even selling power back into the grid.
“Since [we] put the 5kW system in we haven’t paid a power bill,” Mr Lowe told 7.30.
“And there’s been some surplus money out of it.”
Ergon’s emerging markets manager Glenn Waldon described the low price of the Powerwall as a “step change” for the industry.
He predicts Australian energy companies will soon be offering their customers packages similar to the package bundles offered by mobile phone companies.
“Instead of just buying kilowatt hours, you’ll be getting different product wraps and mixes — so capped price options, somewhat like telco or offerings for mobile phone plans,” he told 7.30.
