“It is very simple: We are overloading the atmosphere with heat-trapping gas and the rest is details,” Mr Vesey told an investor briefing in Sydney, where he again forcefully ruled out any investment in new coal-fired power.
He said there were two strategic imperatives that govern all AGL’s investments – affordability and the tenet that the future will be carbon-constrained, making new coal too risky as an investment.
Mr Vesey spent the bulk of his address explaining how AGL would replace the capacity lost at Liddell, including new wind and solar farms, up to 750 megawatts of new gas-fired plants and a 100-megawatt upgrade to the more modern and larger Bayswater coal plant nearby. A 250 MW battery at Liddell and demand response will also come into play, he said.
The Powerwall is a 7 kilowatt hour (kWh) lithium-ion-battery system that stores electricity generated from rooftop solar panels (or PV panels) during the day so that electricity can be used at night during the peak-usage times.
