The head of one of Australia’s biggest electricity networks says he sees no long-term future for large, centralised electricity generators, nor for big electricity retailers. And, he notes, networks are a more trusted source of information, advice and service than retailers. “We’re trusted… customers know we’ll be here in another 20, 30, 40 years.”…expects 70 per cent of customers to have solar and 50 per cent to have storage within two decades. The economics of grid disconnection will fall rapidly, first in regional areas, and then in more built up areas…estimates 70 per cent of its grid costs service just 30% of customers – but costs are shared equally. Regional customers in Queensland and Western Australia are also subsidised by government, or other users, to the tune of $1.2 billion a year.
