The federal government has been set a deadline to provide more detail on its plan to cut power bills and emissions.
Senators agreed on Wednesday to call on Environment Minister Josh Frydenberg to provide documents and detailed modelling on the national energy guarantee by 12.45pm on Thursday.
The Senate order comes as Prime Minister Malcolm Turnbull continues his blitz to convince voters, industry and state governments of the benefits of his plan.
Mr Turnbull will attend a breakfast with members of the Energy Security Board, which came up with the policy, at an Australian Industry Group event in Canberra on Thursday.
The government argues the national energy guarantee will reduce household bills by an average of $110 to $115 a year over the period between 2020 to 2030.
However, Greens senator Peter Whish-Wilson described it as a "half-arsed policy designed to save Malcolm Turnbull's bacon".
The policy has been met with a variety of views from within the coalition.
Nationals MP George Christensen is planning to launch a public campaign to get a coal-fired power station in north Queensland, arguing the new policy needs to be broad enough to cater for coal.
The Tasmanian Liberal government says the policy needs to encourage more renewable energy, which not only cuts emissions but creates jobs.
Mr Turnbull says he's aiming to deliver a triple bottom line - affordable and reliable energy, while cutting emissions.
