The architect of the failed National Energy Guarantee has claimed Australia has sunk into policy "anarchy" as part of a fierce critique of the government's shift to focus on power prices instead of other issues such as reducing carbon emissions.

Energy Security Board chairwoman Kerry Schott said she remained bitter over the dumping of the signature energy plan when Malcolm Turnbull was deposed as prime minister in late August.

“I’m still going through the stages of grief, and I haven’t left anger yet,” Dr Schott told The Australian Financial Review's energy summit in Sydney on Wednesday. “I characterise the general state of affairs right now as anarchy."

The NEG was supposed to deal with a "trilemma" of issues: reducing power prices, improving grid stability and cutting carbon emissions from an industry that is Australia's largest source of greenhouse gases.
