Pipeline operator Williams said Wednesday it would buy six underground natural gas storage facilities with a total capacity of 115 Bcf in Louisiana and Mississippi from an affiliate of Hartree Partners for $1.95 billion.
The deal also includes 230 miles of gas transmission pipelines and 30 pipeline interconnections, including to LNG markets and Williams’ Transco pipeline, the nation’s largest natural gas transmission pipeline.
Natural gas storage — especially well-sited storage with lightning-fast deliverability rates — is taking on a new significance (and value) as LNG export facilities and power generators seek to manage their often-volatile gas demand. But developing new gas storage capacity is costly and, with only a few exceptions, it’s hard to make an economic case for greenfield projects. That reality has spurred a lot of interest among midstream companies in acquiring existing storage assets and, where feasible, expanding that storage. In today’s RBN blog, we discuss one of the biggest storage-acquisition deals to date: Williams Companies’ recent purchase of six facilities with a combined working gas capacity of 115 Bcf in Louisiana and Mississippi. (It’s not all that Williams has been up to on the gas-storage front.)
Storage has long been a critically important balancing mechanism in the Lower 48 natural gas market. Now, after languishing for much of the Shale Era, storage values are coming out of the doldrums. The key driver behind this change is that, unlike in the old days, when the storage market was driven primarily by the intrinsic value of capacity — i.e., the need to sock away gas in the lower-demand summer months for use in the peak winter months — the value of storage is being driven almost exclusively by extrinsic economics — i.e., how flexible and responsive capacity allows market participants to manage supply and demand during short-term market swings. This flexibility and responsiveness have become increasingly important criteria for ensuring reliability as LNG export facilities and an increasingly renewables-heavy power sector navigate frequent demand fluctuations day to day, or even intraday, as well as during high-stakes, extreme weather events like 2021’s Winter Storm Uri. In today’s RBN blog, we delve into the fundamental shifts influencing today’s storage market.
Rising demand for natural gas storage in the Gulf Coast region has spurred growing interest and investment. A number of midstream companies have been making moves, either by expanding their existing storage facilities in Texas, Louisiana, Mississippi and Alabama or entering the space with acquisitions or plans for greenfield projects. As a result, more than 150 Bcf of new gas storage space is in various stages of development. In today’s RBN blog, we discuss highlights from our new Drill Down Report on Gulf Coast gas storage.
