But the opposition says the compensation offer is "just not good enough" given how long some people were without power.

The outages came as heat and humidity on January 28 put crippling pressure on the state's distribution network.

Victorians who lost power for between three and 20 hours will receive $80 in compensation, while those in the dark for more than 20 hours will get up to $180.

Premier Daniel Andrews said the payments were "unprecedented".

"Under the rules that have been there for many, many years, well before we came to government, the payments would only be made to those who had lost power for say, 12 hours," he said on Sunday.

But opposition energy spokesman David Southwick said the premier should not be congratulating himself over the package.

"It's insulting that Daniel Andrews would be patting himself on the back today, saying that he's negotiated a great deal for Victorians," Mr Southwick said.

"We're hearing of energy compensation of around $80 for those who experienced power outages of up to 20 hours. This is just not good enough."

Mr Southwick said Victoria's energy situation was in "crisis" and the premier had no solution.

The payments will be made to about 50,000 people by the end of February and are separate to claims for financial loss.

They will be provided by Powercor, CitiPower, United Energy, Ausnet Services and Jemena as part of a $5 million package.

The Andrews government says it is working with the Australian energy market operator and industry to make sure supply needs are met during extreme weather.
