A fire at Victoria's largest coal-fired power station has decreased its energy output but authorities say there is still enough to keep the lights on.
Firefighters were called to Yallourn Power Station in the Latrobe Valley about 6.20am on Wednesday in response to a blaze in one of the coal storage facilities.
The Australian Energy Market Operator has confirmed the fire "reduced the station's generation capacity" while noting there is "sufficient supply to meet forecast demand in Victoria at this stage".
