Prime minister Malcolm Turnbull is mighty proud of the upgraded rooftop solar array and battery storage system that he had installed in his Point Piper harbourside mansion in Sydney earlier this year. And rightly so – it’s part of a vital new network resource that will help keep Australia’s lights on.
New Australia-wide standard gives networks power to limit size of household solar systems – and could push up prices for AC-coupled battery storage products from Tesla, Enphase, Selectronic and others.
Report from Australia’s main network lobby and CSIRO suggests that by 2050, nearly half of all future generation – and storage – will be on site in homes, business and communities.
Australia’s biggest utilities are passing on the surging cost of the country’s predominantly coal-fired grid to consumers at the start of the new financial year, but it seems pretty clear that many solar households are missing out.
There is a lot of talk about the ability of battery storage to take households and businesses off the grid. But how do the numbers for battery storage stack up for the majority that will remain connected to the grid?
