Super Steep Natgas Forward Curve Contango Justifies Wave of New Storage? Not So Fast.

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. 

The U.S. Energy Information Administration (EIA) on Thursday (June 9) reported a surprisingly bullish 65-Bcf injection for the week ended June 3—that was 8.0 Bcf below our Natgas Billboard estimate and more than 10 Bcf below the Bloomberg industry average assessment. In response, the CME/NYMEX Henry Hub July natural gas contract screamed about 15 cents higher following the report to a settle of $2.617/MMBtu, the highest daily settle for the prompt month in nearly 9 months. Thursday’s gains extended a rally that began on May 31 (2016) just after the July contract rolled to the front of the futures curve. It’s likely the rally was initially spurred by market participants looking to cover their short positions. But in the past week, an increasingly bullish fundamental picture has emerged prompting us to raise our price outlook (in our June 10 NATGAS Billboard report). In today’s blog, we analyze the fundamentals behind rising natural gas prices.

The volume of natural gas in storage and the flow of gas into and out of it are among the most closely watched indicators in the U.S. gas market. That makes sense, given that these numbers provide important weekly insights into the supply-demand balance, gas price trends, the impact of LNG exports, and any number of other market drivers. However, what’s often ignored by those not involved in the day-to-day physical gas market are the mechanics and economics of storage itself. Who uses gas storage, and for what purposes? What are the value drivers for a storage facility? Why are there different types of gas storage contracts? How much does storage cost, and what do storage rates reflect? Today, we explore these and other questions.
