The draft Tasmanian Energy Strategy calls for state-owned power agencies Hydro, TasNetworks and Aurora to be more cost-effective, as well as helping homes and businesses to be more energy efficient.

The strategy identifies Tasmania's renewable energy resources as an advantage in the national network, and recommits the government's support for the national Renewable Energy Target, which faces an uncertain future.

A second Basslink cable would also be investigated under the plan.

Energy Minister Matthew Groom said the government wanted to bring down power prices down as much as possible.

"It's about putting people first when it comes to energy," he said.

"It's about reducing the cost of delivering energy and it's about ensuring Tasmania can take advantage of its extraordinary renewable resources into the future."

The strategy says the government wants to bring all state-owned enterprises back to their main purposes.

"The government recognises that each [electricity] business can further improve efficiency and performance," it says.

Opposition Leader Bryan Green said the scrapping of the carbon price had made Hydro's job much tougher.

"It's also money that won't be going to frontline services," he said.

"The government needs to explain how it will squeeze savings from state-owned energy businesses and whether that will involve job losses."

Greens Leader Kim Booth called the strategy a "smokescreen", and was critical of the push for a second connection under Bass Strait.

"Hiding this Basslink 2 proposal in the tinsel of Christmas is a very worrying development and the sort of Christmas present that will keep on biting families through their power bills for years to come," he said.

The government will accept submissions on the draft strategy until February 15.
