NSW could be hit by blackouts as workers at two Upper Hunter power stations prepare to take industrial action over stalled pay talks.
600 workers at the Bayswater and Liddell power stations, which supply 40 per cent of the state's power needs, are considering overtime bans and stoppages of up to 48 hours.
Fair Work Australia has directed unions to give Macquarie Generation 7 days notice of any industrial action, instead of the normal 3 days so the company can make alternative arrangements if workers walk off the job.
