A fault which has disabled the Basslink undersea power cable connecting Tasmania to Victoria will not be fixed today, Hydro Tasmania says, but the public should not be worried of a repeat of the energy crisis of 2015/16.
The interconnector, which links Tasmania to the national electricity grid, has been out of service since yesterday.
Hydro Tasmania's Gerard Flack said the energy storages were not threatened, with Tasmania's dam reserves at 30 per cent capacity.
"We understand that the fault's at a converter station, so something to do with the control system and electronics," he said.
"It's not a cable fault, so it's not like we had back in 2015. The storage is very healthy at 30 plus per cent and rising at this time of the year.
"My view is that it's a minor issue."
Mr Flack said it was unlikely the issue would be resolved today.
The outage comes three years after the state was plunged into a six-month long energy crisis in 2015/16 when the undersea power cable failed.
The energy crisis was triggered by the failure of the Basslink cable that connects Tasmania to the national electricity grid, combined with a shortfall in Hydro Tasmania's dam levels.
Energy analyst Marc White said while it was too early to speculate what caused the current fault was, he was not overly concerned.
"It looks like the import and export flows have been fairly modest at the time of the outage and this might be because of constraints on the system or price implications," he said.
Outage means financial losses mounting up
Mr White said the outage shouldn't have any impact on Tasmania's electricity supply.
"We wouldn't expect the issues we suffered from a couple of years ago would be recurring again since a number of initiatives have since been put in place from what is now a foreseeable event," he said.
Mr White said energy storage levels were operating at 31.7 per cent, which is 3 per cent lower than the 10-year average for this time of year.
He said the outage is having both a physical and financial impact on both the Victorian and Tasmanian energy systems.
Unable to trade during the outage, Mr White said Hydro Tasmania could possibly be losing thousand of dollars with each hour that passes.
Basslink are in legal dispute with both Hydro Tasmania and the State Government over who is to blame for the six-month outage that stopped electricity imports and exports in Tasmania.
Both parties are expected to enter mediation talks later this year.
