What happened

Just after 8pm on Saturday, a bright green flash and two bangs were reported at two power transformer stations around Trevallyn in Launceston. Power was cut to much of the city's west, including Trevallyn, Riverside and parts of the CBD and Kings Meadows. TasNetworks said crews were on site working to restore supply. The cause, the extent of equipment damage and whether anyone was injured were not reported.

Contributing factors

Not reported.

Lessons learned

  1. A flash and bang at a transformer station can leave a wide area without power before the fault is confirmed.
  2. Ask customers to call the fault centre only for downed or damaged lines, so the line stays free for real hazards.
  3. Early public updates should say what is known and what has not yet been checked.
