Northwest Natural Gas Co. this afternoon restored service to homes and businesses in Northwest Vancouver that may have lost heat earlier today.
Natural gas compressors at the Jackson Prairie storage facility south of Chehalis failed around 6 a.m., causing pressure to fall in the company’s supply line to the Hazel Dell and Felida neighborhoods, according to NW Natural and Williams Northwest Pipeline Co.
Unusually cold weather overloaded the compressor at the same time delivery from another source was blocked — a rare combination of events that caused disruption in service, said Michele Swaner, a spokeswoman for Williams, which owns the storage facility with Avista Utilities and Puget Sound Energy.
Pressure was restored for about 75 percent of NW Natural’s affected customers by 10:30 a.m. and service was fully restored by 2 p.m., according to the utility.
