Storage Capacity

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. 

In just a few months, heavy crude from Western Canada will start flowing south on the Capline pipeline from the Patoka, IL, hub to the one at St. James, LA. While the initial volumes will be modest, Capline’s long-awaited reversal will provide Louisiana refineries and export terminals with easier, lower-cost access to oil sands and other Alberta production. Flipping the pipeline’s direction of flow also means more changes for the St. James storage and distribution hub — one of the U.S.’s largest — which has already seen more than its share of evolution during the Shale Era. Today, we continue our Capline/St. James blog series with a look at St. James’s terminals and pipelines, the Louisiana refineries they supply, and the changes coming with the Capline reversal.

It’s been a mantra in the energy industry for a few years now: more Canadian and Lower-48 crude oil needs to move to the Gulf Coast, with its bounty of refineries and export docks. And that’s been happening, thanks to a slew of new and expanded pipelines and new tankage. Similarly, new export capacity has been developed, and a number of refineries in Texas and Louisiana revised their crude slates to take advantage of what looked like an ever-rising supply of North American crude. Yet another piece of the puzzle will slide into place in January 2022, when crude oil — most of it heavy Western Canadian — will start flowing south on the newly reversed, large-bore Capline pipeline from the Patoka hub in Illinois to the impressive collection of terminals in St. James, LA. Today, we continue our series on the market impacts of Capline’s upcoming reversal on St. James, Louisiana refineries and crude exports.

On Friday (March 4, 2016) the April NYMEX/CME futures contract settled at $1.666/MMBtu, the lowest contract settlement since 1999. Rock bottom prices reflect a growing supply/demand imbalance and concerns about hitting storage capacity limits later this year. Last Thursday’s EIA report showed U.S. gas inventory stands 827 Bcf above last year at this time and 687 Bcf above the 5-year average. These are the biggest surpluses the market has seen since 2012. Moreover, our latest NATGAS Billboard storage outlook shows March withdrawals lagging way behind last year and expanding the surplus further heading into April. In today’s blog, we look at how a similar situation was resolved in 2012 and what it will take to bring down the surplus this year.

The U.S. natural gas market is facing an ultimatum. Natural gas storage inventories are carrying such a daunting surplus, that prices already at 21-year lows for December, seem primed to go even lower should supply or demand fail to cooperate and balance the market. A warm winter so far and the very real prospect of hitting a storage celling before next winter mean that something has to give.  Today we wrap up our series on the gas supply/demand balance with a look forward to how 2016 could pan out.

Prior to 2012 the only U.S. produced crude delivered by pipeline to Houston area refineries came from offshore Gulf of Mexico or onshore Louisiana fields. The majority of supplies were imports delivered by waterborne tanker. But in just three short years between 2012 and 2015, roughly 2 MMb/d of crude pipeline capacity was built or repurposed to deliver surging light shale crude production and heavy crude from Canada into the Houston area. Refiners have adapted quickly to take advantage of new sources of supply. But with much of the newly minted infrastructure underutilized, midstream companies still need to improve pipeline connectivity and storage accessibility to overcome area logistical challenges. Today we review RBN’s latest Drill Down report on Houston crude infrastructure – released today -- and announce RBN’s new infrastructure database and mapping system, called MIDI.

Close analysis of Houston area crude storage indicates it is only 52% utilized today even as regional crude inventories have reached record levels. Meeting refinery operational needs appears to be the main use of area storage – rather than speculative gains from buying today’s cheap oil to store and sell later. Today we continue our analysis of Houston area refinery infrastructure.

Analyst estimates for this week’s Energy Information Administration (EIA) Weekly Natural Gas Storage Report before its release were rallying around an expectation of a 95-Bcf injection, according to the Wall Street Journal’s survey of storage analysts. The actual number reported by EIA yesterday (July 16, 2015) was a 99-Bcf injection, more or less in line with analyst expectations. But predictions may get a bit harder later this year. The EIA is preparing to redraw its US natural gas storage map and begin reporting inventory data in new regions later this year (2015). In August, prior to the launch of the revamped report, it will release a file with historical data for each of the new regions. The historical data will for the first time allow modelers to run their regressions and gather statistical information by which to rebuild their storage models designed to foretell the weekly EIA storage number. In the meantime, we did our own unscientific analysis of the regional breakdown and how it will change transparency in gas storage activity. Today, we examine storage capacities in the old versus new regions and potential impact on analyst visibility.
