Niska Gas Storage

Niska Gas Storage is the largest independent natural gas storage company in North America. Niska owns and operates approximately 170 billion cubic feet (Bcf) of working gas capacity in three facilities: the AECO Hub™ (comprised of the Countess and Suffield facilities) - 129 Bcf in Alberta, Wild Goose - 29 Bcf in Northern California and Salt Plains - 12 Bcf in Oklahoma. We also utilize term contracts for storage capacity from other providers. Niska expects to soon own and operate upwards of 200 Bcf of working gas and will continue to fortify its position as a leader in independent gas storage.

Niska also provides natural gas marketing services to the Oklahoma energy market as a natural extension of its commercial storage activities in the mid-continent region.

In Canada, Niska responded to the growing need for commercial, industrial and retail natural gas marketing services by forming Access Gas Services, a wholly-owned subsidiary established in October 2006, to serve markets in the lower mainland and interior of British Columbia. In 2008, Access Gas Services Ontario was established to serve similar markets in Eastern Canada, and EnerStream Agency Services was formed to provide agency services to natural gas end-users in Eastern Canada

Niska is 100% owned by energy-focused private equity funds managed by Riverstone Holdings LLC. The name, ‘Niska’ is a Cree Indian word meaning "Canada Goose" reflecting Niska’s roots as the Canadian developer of the first major trading point for natural gas in Alberta, the AECO Storage Hub who then "migrated" its expertise into the United States.
