Niska Gas Storage Partners LLC operates as a leading independent owner and operator of natural gas storage facilities in North America, providing storage services to utilities, producers, marketers, pipelines, power generators, and financial institutions; its core assets include the AECO Hub comprising Countess and Suffield facilities in Alberta, Canada with approximately 135-154 Bcf working gas capacity, Wild Goose in northern California with around 29-75 Bcf capacity, and Salt Plains in Oklahoma with 13 Bcf capacity, plus contracted capacity in the U.S. Mid-Continent totaling roughly 243.9-250.5 Bcf of working gas across interconnected pipeline networks for multi-cycle injection and withdrawal flexibility. Headquartered in Houston, Texas with key operations in Calgary, Alberta, Canada, the company founded in 2006 focuses on midstream natural gas services in strategic producing and consuming regions of Canada and the United States. In recent years, Niska Gas Storage Partners agreed to a definitive acquisition by Brookfield Infrastructure Partners LP and institutional partners in 2015 for approximately $912 million including debt at $4.225 per common unit, a transaction that transferred control of assets including Wild Goose storage; subsequent developments integrated its facilities under entities such as Rockpoint Gas Storage Canada ULC, which now manages expanded portfolios including six Alberta and California sites with 279.2 Bcf effective capacity, and Access Gas as a wholly-owned subsidiary formerly under Niska.
