‘A train wreck’: what happens to workers and towns when the lights go out on coal power?

When Jacqui Coleman heard that Australia's largest coal-fired power station was to close seven years earlier than planned, she initially didn't believe it.

Coleman is a retail worker in Dora Creek, the closest suburb to the Eraring power station on the shores of Lake Macquarie in New South Wales.

For years, she has been selling pies, coffees and sandwiches to some of the hundreds of workers who pass through the News 'n' More grocery store on either side of a shift.

On Thursday morning, Origin Energy announced it was bringing forward the station's closure to 2025.

Many workers at the site first learned their jobs were to be terminated seven years early when they heard it reported on the radio.

As Coleman heard one customer after another talking about the news, she said "it hit home that it's really happening".

"I feel for all of the people whose jobs are going to be lost, especially when some of them have been there for so long. What are they going to do?" she said.
