Shortly after Basslink announced bad weather would halt repair works until at least March 17, Labor senator Carol Brown said her party would back an inquiry into the management of the state's energy resources.

Greens senator Nick McKim also supported the move, saying an inquiry would provide a fresh opportunity for the state to look at alternative energy solutions.

"While we need to understand how we ended up in this situation, there is a real opportunity to think about what Tasmania needs to do - short, medium and long term - to provide renewable energy security at the lowest possible prices," Senator McKim said.

"Global warming will continue to impact on rainfall in many of Hydro's dam catchments, and as we've already seen, there are economic, social and environmental costs to not getting it right."

Energy Minister Matthew Groom welcomed an inquiry and said he would have more to say on the subject "very soon".

The Basslink interconnector is expected to be repaired by late May.
