MISO High-Risk Status and the Data Center Cost-Shift: Indiana Grid High-Risk Warning Is Getting Worse

Daniel BurkePublished every day

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.

FERC Section 206 proceedings and MISO's corrective transmission projects across multiple Indiana utility systems create a live collision with the AES and Duke rate cases. If those transmission upgrade costs get allocated to existing ratepayers rather than to the hyperscalers driving the load growth, model what a 10 to 15 percent increase in your transmission and distribution charges does to your per-unit cost structure.

Q

What does MISO high-risk status mean for Indiana manufacturers' electricity costs?

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.
