Steel Dynamics $534M Quarter, Indiana Grid High-Risk Warning, Crane Nuclear Reactor, and AES Rate Rehearing: TEG Daily September 10, 2026
MISO flags Indiana's grid zone high-risk, AES rate rehearing sets the ROE floor, Steel Dynamics backlogs hit Q1 2027, and the Pentagon opens a nuclear supply chain…
MISO has reclassified Indiana's grid zone as high-risk for resource adequacy, and it is happening simultaneously with a $534 million Steel Dynamics quarter, a Pentagon nuclear reactor announcement at NWS Crane, and an unsettled utility regulatory structure that will set energy cost floors for every investor-owned utility in the state. Four stories. One pressure point on your cost structure, your energy bill, and your contractor availability heading into 2027.

Steel Dynamics Posts $534M Quarter, Indiana Steel Buyers Face Q1 2027 Backlog Risk
Fort Wayne-based Steel Dynamics reported Q2 2026 results on July 21: record quarterly shipments of 3.7 million tons, net sales up 33% to $6.1 billion, and net income nearly doubling to $534 million. The mechanism behind those numbers is precise and worth understanding.

AES Indiana Rate Rehearing: The ROE Fight That Sets the Floor for Every Indiana Utility
Indiana Utility Consumer Counselor Abby Gray filed a petition for rehearing challenging the IURC's June approval of a $71 million AES Indiana base rate increase. The OUCC is contesting a 9.5% approved return on equity (they want 9.1%) along with a $3 million rate case expense pass-through and a payroll adjustment tied to over 100 vacant positions that the OUCC says produced a compensation windfall of more than $15 million.

Pentagon Announces Indiana's First Nuclear Reactor at NWS Crane, Supply Chain Window Opens Now
The Department of Defense announced September 10 that it will install an advanced Micro Modular Reactor at Naval Weapons Station Crane in Martin County by September 2028, the first power-producing nuclear reactor in Indiana's history. The project runs through the Army's Janus Program.

MISO High-Risk Status and the Data Center Cost-Shift: Indiana Grid High-Risk Warning Is Getting Worse
MISO's resource adequacy assessment for the Indiana grid high-risk zone reflects a deteriorating picture driven by coal retirements, slower-than-planned generation interconnection, and rising large-load requests, including hyperscaler data centers. Representative Spartz's letter to DOE and Interior on September 9 names the jurisdictional gap directly: FERC told state commissions that protecting ratepayers from transmission cost shifts is their job, not FERC's, and Indiana's IURC is simultaneously the same body being reconstituted under political pressure.
Questions for Your Morning Huddle
Q: What does MISO high-risk status mean for Indiana manufacturers' electricity costs?
A: MISO's high-risk classification for Indiana's grid zone signals that the region may not have adequate generation capacity to meet peak demand as coal plants retire and large new loads (including data centers) come online faster than replacement generation. For manufacturers, the near-term consequence is upward pressure on capacity charges and transmission costs, with potential reliability exposure during peak periods. Model a 10 to 15 percent increase in your transmission and distribution line items as a planning scenario.
Q: How does the AES Indiana rate rehearing affect other Indiana utilities?
A: The ROE the IURC ultimately approves or denies in the AES rehearing establishes the reference point that Duke Energy Indiana and the other three investor-owned utilities in the state will use in their own pending and upcoming rate cases. A higher approved ROE means a higher cost floor for every rate case that follows. The outcome of this proceeding will influence what every Indiana manufacturer pays for electricity for the next several years.
Q: Should Indiana steel buyers lock in supply agreements now?
A: Steel Dynamics' backlogs extending 45% above year-ago levels into Q1 2027, combined with Nucor's 92% earnings increase in the same period, confirms that EAF producers are structurally capturing tariff-era margins, not experiencing a temporary spike. Indiana steel buyers exposed to spot pricing at current levels should review supply agreement terms, volumes, and pricing mechanisms against mid-2027 exposure before backlog windows close further.
Q: How can Indiana manufacturers enter the Crane nuclear supply chain?
A: The Janus Program vendor has not yet been named, which means the supply chain has not closed. Companies with existing supplier relationships, quality certifications, or operational footprint touching the defense tech or nuclear ecosystem at NWS Crane or WestGate @Crane should assess their procurement eligibility now. Once the vendor is announced, the tier-one supply chain will fill quickly. The 24-month window before the September 2028 deadline is the entry point.
