The chair of Australia's Energy Security Board will move away from the role at the end of next month, as the body undergoes an overhaul.
Kerry Schott will step down from the position on October 31 as part of a reform measure agreed to by federal, state and territory energy ministers.
The proposed reform of the board would see its membership limited to the heads of Australia's three main energy market bodies, with the leader of the Australian Energy Market Commission expected to be the new chair.
However, energy ministers will still be able to appoint an independent chair to the board if needed.
A readout of the latest meeting of energy ministers paid tribute to the work of Dr Schott and deputy chair David Swift.
The latest energy ministers' meeting came amid criticism of the federal government by some jurisdictions over proposals to get power retailers to pay subsidies to keep coal and gas-fired power stations operating.
Ahead of Friday's meeting, Victoria and the ACT's ministers said they would not support the measures, which had been dubbed "CoalKeeper".
The proposal had also attracted criticism from some renewable energy groups, who said would stifle investment in the sector.
Minister agreed to the final package of reforms to the national electricity market, which would be taken to national cabinet for approval next month.
"Ministers also agreed to progress further design work on a mechanism that specifically values capacity in the national energy market," the readout of the meeting said.
"This is to be underpinned by principles that ensure the design for a market mechanism delivers investment in an efficient mix of variable and firm capacity, that meets reliability at lowest cost."
The government had indicated it wanted to introduce reliability obligations for providers to make sure there was enough electricity in the market when demand for renewables such as wind and solar could not be met.
"The full suite of reforms will ensure the national energy market remains fit for purpose and capable of providing the full range of services necessary to deliver an affordable, secure, reliable and lower emissions electricity system for consumers," the readout said.
