Project Name*:

AltaGas has reached a positive final investment decision on the Phase One expansion of the Dimsdale natural gas storage facility, west of Grande Prairie. Backed by two 10-year firm storage service contracts with Tourmaline Oil and Gunvor Group, the expansion will increase usable storage capacity from 15 billion cubic feet (Bcf) to 21 Bcf through improved equipment utilization, facility debottlenecking, construction of a new meter station and pipeline interconnect.
