The next steps for the National Energy Guarantee:
* Prime Minister Malcolm Turnbull will brief cabinet colleagues on changes to the energy plan at a dinner at The Lodge on Sunday night.
* Tweaks include setting a "price expectation" defining the most any Australian should pay for power, coupled with penalties for power companies that charge too much.
* Future governments wanting to change Australia's carbon emission reduction targets would also be compelled to reveal its impact on power bills.
* The prime minister is also expected to propose the country's carbon reduction targets be set by regulation, rather than legislation, to build support for the National Energy Guarantee.
* Just last week, Mr Turnbull said regulation would deny the parliament a voice on the policy.
* The changes will be up for debate during a coalition partyroom meeting at Parliament House on Tuesday.
* Labor is reserving its right on whether or not to back the energy plan.
* The opposition has released its own energy proposals, which also include a default power price, allowing people to compare what they are paying to what they should be.
* The Greens are pressuring Labor not to back the government's plan, saying it would make it easier to weaken emissions reduction targets.
* States and territories last week released draft laws for their part of the NEG, locking in penalties for power companies that don't meet emissions reduction targets or reliability measures.
* The Energy Security Board will consult on the laws for four weeks, then refine them for two weeks before a decision on the guarantee is made.
