The pre-Christmas 2015 failure of the Basslink cable from Victoria has thrown a googly into Tasmanian electricity supply. Most of their supply is from Hydro, the last two years rain has not been stellar and storage levels are under 17% now. They have gas supplies from Gippsland and have gas fired generators. Nemwatch gives real time snapshots of what each source is contributing. Wind has less capacity than gas – thats when the wind blows. The State Govt which owns the Hydro and most other generation – is importing 200 diesel units to help through and the unions want their share. Then they can always turn off industrial customers if they have to. Basslink is taking longer to repair than was first thought.
