The Australian Gas Light Co Ltd said it was working with big industrial and commercial customers to minimise the impact of a fire at Santos Ltd's Moomba Plant that led to major loss of gas supply. "AGL is sourcing additional quantities of gas from the Bass Strait in Victoria to meet as much of our customers' current requirements as possible," AGL's group manager for external and regulatory affairs Jane McAloon said. "However, if the Moomba plant outage continues beyond next Monday this situation will be reassessed."
