Last evening, routine maintenance was being conducted on a gas line from a gas supplier company that feeds the Peoples system. A valve was closed that feeds the Peoples system and Peoples lost gas to approximately 400 customers. When customers began to call Peoples Customer Service, Peoples dispatched field workers to determine the cause. Once identified, the supplier company was requested to correct the situation. Over 50 People’s employees were dispatched to aid our customers. This process includes safety checks of customer owned pipelines and equipment and then entering homes to relight appliances. Customers should not attempt to relight their own appliances. We will continue to relight appliances throughout the day and evening. As the process continues, updates will be posted on Peoples website at peoples-gas.com. We apologize for any inconvenience to our customers and our crews will continue to work and be on standby throughout the evening.
