Three cushions the bullish MISO real-time trade is ignoring

Three cushions the bullish MISO real-time trade is ignoring MISO real-time positioning has leaned bullish on outage risk, but emergency capacity, in-the-money coal and loose gas storage are three supply cushions the tape is underweighting. NERC's Summer Reliability Assessment, published Wednesday (2026-06-03), confirms that federal regulators renewed emergency orders holding aging generators available into late May and early June, units the report says were not built into the anticipated resources of their assessment areas but can be called on within the orders' time frames.⁴ That matters because the consensus on MISO real-time has tilted bullish, leaning on outage-driven tightness as the summer dispatch season opens. Our signal aggregation shows 16 directional reads on MISO real-time, with bullish weight running better than two-to-one over bearish. Yet the conviction is thinner than it looks. Net bullish strength sits at just 42%, and one of the loudest opposing reads is a high-confidence bearish call on supply. The market is pricing scarcity into a balance that has at least three cushions the tape is underweighting.⁴ Start with the emergency capacity itself. Those plants do not appear in MISO's official resource count, so any reserve-margin math built off the headline number understates what the grid can actually dispatch on a hot afternoon. They are expensive and they are a last resort. But last-resort megawatts are exactly what cap real-time spikes, and their existence is now documented rather than assumed.⁴ The second cushion is coal, and the economics are not subtle. EIA data published Wednesday (2026-05-20) show coal stayed competitive for power generation across the Midcontinent through the first four months of 2026, with the coal dark spread up 111% in 2025 versus 2024 as wholesale power prices climbed faster than coal fuel costs. Average MISO electricity prices rose 44% over the same stretch. The spark spread, by contrast, widened only 18% because rising gas generation costs ate into the gain. When coal is this far in the money, it dispatches ahead of gas peakers and blunts the price response to any single outage.² The third is the fuel itself. Working gas in storage fell 52 Bcf in the week reported Thursday (2026-05-21), well short of the 168 Bcf five-year average withdrawal, and inventories sat 141 Bcf above a year earlier, about 8% higher. Front-month NYMEX natural gas was trading below $3/MMBtu, dipping toward $2.75 before settling near $2.86. Loose storage and cheap gas pull down the marginal cost of the units that set MISO's real-time clearing price. That is a bearish force on power, not a bullish one.¹ None of this means the bulls have nothing. MISO's own Seasonal Readiness material, dated Wednesday (2026-06-03), flags that the Winter 2025-2026 Planning Resource Auction cleared with fewer surplus zonal resource credits than the prior winter, the kind of tightening that justifies some scarcity premium.⁵ And the demand story is real: regional grid operators are already wrestling with data center load that Grid Strategies projects will add at least 65 GW and as much as 90 GW nationally by 2029.³ But 2029 demand does not clear a June 2026 real-time interval. Conflating a multi-year load build with this summer's hourly prints is how crowded trades get built. The bullish case rests heavily on outages, and outages are the one variable the emergency orders were written to offset. What would settle it. Watch whether MISO actually invokes the emergency-order capacity during the first real heat event, because a single dispatch confirms the buffer is live rather than theoretical. Watch the next EIA storage print against that 168 Bcf five-year benchmark; another sub-average draw with inventories holding 8% above last year keeps the fuel cushion intact. And watch the coal dark spread. If it stays positive and wide, coal keeps backstopping the stack and the bullish real-time thesis narrows to weather alone. If the spread collapses and storage tightens fast, the bears lose their floor and the consensus is right after all.²
