The Greens are set to move a motion in the Senate on Monday seeking to pull back the curtain on the calculations behind the federal government's energy promises.

Senator Richard Di Natale will call on the government to release the full modelling for the proposed final design of the National Energy Guarantee to enable scrutiny of the government's claim that it will result in lower emissions and power bills.

Greens energy spokesman Adam Bandt MP said the government was yet to provide sufficient detail on the plan, which aims to guarantee the reliability of the power network and curb rising prices while cutting emissions.

"We need to see the full modelling behind these outlandish claims before decisions get made about the NEG," Mr Bandt told Fairfax Media on Sunday.
