CALGARY, Alberta (Reuters) - Canadian spot natural gas prices dipped on Thursday as U.S. data showed a larger-than-expected build in storage volumes.
Spot gas at the AECO storage hub in southeastern Alberta slipped 1 Canadian cent to average C$1.70 a gigajoule. Deals were done between C$1.66 and C$1.74 a GJ.
The U.S. Energy Information Administration said inventories in the United States rose by 42 billion cubic feet last week, compared with a Reuters survey estimate for 34 bcf.
Canadian storage volumes rose 0.5 percent to 492.5 bcf. Canadian Enerdata said facilities across the country were 69.5 percent full on average, compared with just 26.9 percent 12 months earlier.
