Two protesters at a coal and energy conference at Traralgon have been charged with trespass.
Police say a Melbourne man and woman were arrested after they tried to disrupt the conference this morning.
More than a dozen protesters called on the State Government to shut down the Hazelwood power station by 2012.
Protester Kristy Henderson says Hazelwood is the dirtiest coal-fired power station in the western world.
“Hazelwood is an old dinosaur. It should have been shut down in 2005. In fact, that was an ALP promise and it was expanded and extended until 2031,” she said.
The Energy Minister, Peter Batchelor, says Hazelwood can not be shut down in the short term, because it would cause widespread power outages.
