Upper Peninsula Michigan has reached 74.4 on the DCPI excess-power index this week, positioning it as MISO's second-strongest build market and marking a sustained climb in a corridor historically overshadowed by Texas and Southwest dominance. Its constraint score of 19.0—among the lowest friction readings across all 280+ tracked US markets—indicates grid acceptance of new load with minimal transmission friction.
**What it means for capacity planning**: The UP's position reflects a deliberate shift. MISO's 39 tracked data-center markets average 50.1 excess power; Upper Peninsula's 74.4 places it in the top quartile. For hyperscalers evaluating second-wave build sites outside ERCOT saturation, the UP offers both land availability and grid headroom that competes with Cheyenne (72.5 constraint 28.5) and matches the risk profile of established Texas corridors without the transmission competition.
**The wider read**: MISO's Midwest footprint—spanning Michigan, Illinois, Wisconsin, and Minnesota—is emerging as the primary relief valve for US data-center load. While Midland–Odessa remains the single highest-excess market (85.7), its constraint is rising as build density increases. The UP's low constraint alongside high excess power suggests grid operators have capacity to absorb the next wave of deployment without the bottleneck-management costs appearing in Southwest markets. For investors and operators, MISO's distributed market strength reduces single-point-of-failure risk in a way concentrated ERCOT exposure cannot.
**Methodology**: DCPI excess-power and constraint indices reflect live 24-hour grid telemetry, facility-level capacity availability, and interconnection queue position across 20,000+ tracked assets. Scores are normalized 0–100; excess power measures available headroom, constraint measures transmission friction. Upper Peninsula Michigan (MISO) data refreshes daily at 17:00 UTC.
