The Finkel review presents a "once-in-a-generation" opportunity to fix Australia's energy system and must be backed by state and federal governments at their energy meeting on Friday, the head of market operator AusNet Services says.

Nino Ficca, whose company runs Victoria's entire electricity transmission network, as well as electricity and gas distribution businesses, warned politicians that "continued partisan politics will lock in poor outcomes for customers".

Chief scientist Dr Alan Finkel has come up with recommendations to improve the National Energy Market, including a clean energy target to encourage the switch to renewable sources such as wind and solar and cleaner coal-fired power generation.

Analysis from energy consultancy company Global-Roam last week showed that national wholesale power prices in the second quarter jumped between 155 and 239 per cent between 2015 and this year.

Victorian households have been warned to expect higher power bills when prices are readjusted in the first quarter of next year.

The Council of Australian Governments' (COAG) Energy Council is meeting in Brisbane on Friday.

Mr Ficca said Dr Finkel's ideas should be endorsed to provide policy certainty for businesses and households.

"Alan Finkel and his team have delivered a sensible set of recommendations with a long-term focus, sure there's lots of details to work through but of course the principles we believe are sound, we strongly support those recommendations," he told an industry lunch in Melbourne on Tuesday.

"This remains, I believe, a once-in-a-generational reform opportunity to get energy policy back on track."

Mr Ficca spoke alongside former New York utilities regulator, now head of the Australian Energy Market Operator (AEMO), Audrey Zibelman.

She also urged COAG to back the Finkel review saying "there's no question that there's a path forward and we need to take it" to allow for important investment in power generation and transmission networks.

Ms Zibelman told the crowd that once the Finkel review was supported by governments, market regulators needed to shape the recommendations into a clear road map with milestones to assess what progress was being made.

"We need to come up with an actionable plan with details, bring them back to the COAG so they have the confidence that what we're coming up with is something that people will invest in and stand up for."

Zibelman's first 100 days

In March, Ms Zibelman took over the top job at AEMO - which was set up in 2009 to manage the national electricity and gas markets - after the death of its founding chief executive Matt Zema.

She formally chaired the New York State Public Service Commission, which manages electricity, gas, water and other utilities.

AEMO has previously warned about the risk of blackouts during times of strong demand next summer, amid tight gas supplies and increasing intermittent wind and solar generation.

Ms Zibelman said keeping the power on next summer was currently the "biggest focus" for AEMO, as the rate of change in power generation was unprecedented.

"On wind, [nationally in] 2008 we had 1,100 megawatts, we're now at 4,000," she said.

"In solar we were at zero, we're now at 265 [megawatts]."

She said a comprehensive plan was needed to improve the operation of the national energy market and allow businesses to make "no regrets" investments in the system.
