Read carefully. This is part of the "Structural Change" that should keep ngas prices high in 2023 and 2024.

Surprising 2022 coal vs. gas trends have not abated – and likely won’t next year either. Although U.S. natural gas prices have retreated from the highs of the last few months, today’s prices are still well above average compared to the last ~10 years. This caught many investors and analysts “flat-footed” because the U.S. natural gas inventory picture is not materially different from year’s past. In the image below left, we show that there’s typically a moderate relationship between inventory variances and prices. The image also illustrates that current inventories are squarely in the range of outcomes the U.S. market has seen dating back to 2014 — only a modest deficit to the five-year average. Meanwhile, pricing has been materially higher than in periods of similar (or worse) inventory deficits in 2014, 2018, and 2019. We believe one major contributing factor is less sensitivity between natural gas burned at power plants and prices within the U.S. marketplace.
We believe “price inelasticity of demand” has increased for natural gas within the U.S. power sector. As we’ve noted of late, the biggest surprise in our U.S. natural gas model so far this year is not either producer capital discipline, or high U.S. LNG exports it is the limited switching between gas and coal-fired power generation YTD despite high gas prices. At the beginning of the year, we anticipated ~1.5 Bcf/d of “loosening” in the natural gas market in “gas year” 2022 from coal taking power generation market share, or about 550 Bcf or 10-15% of season ending storage. That forecast assumed U.S. natural gas prices maintained the ~$4/MMbtu level after the 4Q21 spike, but prices have averaged closer to $6.00 since then (even peaking at >$9). Despite those higher prices, coal has not taken share back from natural gas — totally counter to industry intuition. As shown in the image below right, although Henry Hub prices have ranged between $3.50 and $9.50 this year, natural gas has actually held steady at 60-65% of U.S. thermal generation. One can see how this outcome clearly contrasts with the historical downward slope to the relationship in a normal environment usually higher natural gas prices lead to lower natural gas consumption.
If you’re only focused on traditional oil & gas markets, you may be surprised to know that U.S. coal prices have actually kept up with those of U.S. natural gas. Despite higher U.S. natural gas prices in 2022 vs. 2021, U.S. natural gas supplies are a very cost competitive feedstock relative to coal supplies on a fully adjusted basis. Coal is actually quite cost competitive with natural gas on a heat content basis (i.e., $/MMBtu); however, coal-fired plants generally suffer from reduced efficiency when compared to their natural gas counterparts. We decided to compare using the EIA conversion rates of ~0.9 kWh/lb for coal and ~0.14 kWh/cf for natural gas, showing a clear advantage for natural gas. However, remember that heat rate variances suggest roughly a ~1.4:1 relationship for gas/coal break-even pricing (e.g., ~$10 gas = >$7 coal). This means, on a fully adjusted ($/kWh) basis, U.S. coal was actually ~25-30% cheaper than natural gas on average in 2021, yet perhaps only ~15% cheaper in 2022. In other words, U.S. natural gas is actually more economically competitive vs. coal in 2022 despite much higher natural gas prices. While there are several factors to consider, we believe this is likely the largest reason why U.S. coal-fired power generation has been slow to take market share from natural gas.
Why are coal prices elevated? U.S. coal inventories were ~30% lower to start 2022 after strong demand in 2021 (when coal actually took market share). Since then, there’s been no recovery in inventories into winter 2022-23. Further, we don’t anticipate coal inventories ending next year materially higher than even those 2021 levels. Additional factors such as coal retirements and rail logistics constraints are also playing a role in limited switching, but supply/demand tightness and elevated prices are the bulk of the story, in our view. All in, we’re not expecting any increase Y/Y in U.S. natural gas-to-coal switching regardless of high natural gas prices...and switching is likely to remain limited in future years.
