Environmentalists say they will continue to protest against a new coal-fired power plant in the Latrobe Valley.
Melbourne company, HRL, was given environmental clearance on Friday to build the plant, which uses gas from brown coal to produce electricity.
About 300 protesters gathered outside State Parliament this afternoon, to oppose the plan.
Protesters climbed onto the roof of the Windsor Hotel to hang a banner, calling for the project to be scrapped.
Julian Vincent from Greenpeace says they will pressure potential investors to abandon the plans.
"We're going to tell investors, super funds, bank, joint venture partners, whoever it may be, that this is a project, that if they get associated with, there's going to be a massive community campaign all over them," he said.
Mark Wakeham from Environment Victoria says there is huge public opposition to the project.
"We are all absolutely united in the fact that we cannot tackle climate change if we are building new coal-fired power stations," he said.
