Natural gas storage

Enbridge’s integrated flexible storage assets give us the unique advantage that will provide critical balancing needs for diverse markets. Our storage facilities provide natural gas producers and shippers with much-needed working capacity and the flexibility of interconnections with major pipelines to reach a variety of markets.

We have about 440 billion cubic feet (Bcf) of net natural gas storage capacity through our assets based across North America. This includes about:

  • 159.3 Bcf of net working storage from our U.S. storage operations in Louisiana, Maryland, Pennsylvania, Texas and Virginia
  • 280 Bcf of net working storage through our storage operations at the Dawn Hub and Enbridge Gas Inc. locations in southwestern Ontario
