State-by-State Industrial Rate Breakdown
| State | At Publication | Current EIA | Primary Driver |
|---|---|---|---|
| Montana | 5.97¢ | 6.90¢ | Hydro (Hungry Horse, Libby Dam) |
| New Mexico | 7.12¢ | 5.65¢ | Solar + legacy coal baseload |
| North Dakota | 7.84¢ | 8.27¢ | Wind + associated Bakken gas |
| US National Avg | 8.88¢ | 8.95¢ | Blended all sources |
Montana: Hydroelectric Advantage Under Pressure
At publication, Montana’s industrial benchmark was 5.97¢/kWh; the current February 2026 EIA benchmark is 6.90¢/kWh. This pricing floor is anchored by federal hydroelectric dams operated by the Bonneville Power Administration (BPA) and Western Area Power Administration (WAPA), which deliver baseload at cost to co-ops and public utility districts.
However, BPA’s decision to join SPP Markets+ (effective 2026) introduces new market clearing dynamics. Industrial customers currently receiving cost-based hydro allocations should monitor SPP integration closely — market-based dispatch could erode Montana’s structural advantage by $0.005–0.008/kWh within 2 years.
Data center siting note: Colstrip’s announced Phase 4 retirement (2027) will remove 740 MW of baseload. Large loads considering Montana should secure interconnection agreements before this capacity exits.
North Dakota: Bakken Gas Keeps Rates Low
At publication, North Dakota’s industrial benchmark was 7.84¢/kWh; the current February 2026 EIA benchmark is 8.27¢/kWh. The state’s industrial cost profile benefits from the Bakken shale formation’s associated gas production. Flare-gas-to-power projects and pipeline proximity mean industrial users in William and McKenzie counties can negotiate block-and-index contracts well below many regional alternatives.
Wind generation now accounts for 35% of North Dakota’s total nameplate capacity, creating negative nodal pricing events during low-demand periods. Industrial users with flexible operations can capture sub-4¢/kWh pricing during spring/fall shoulder months by structuring contracts around these surplus windows.
- Key risk: MISO Transmission Zone 1 cost allocation. MISO’s $8.8B MTEP 26 plan will socialize transmission costs across all load-serving entities. North Dakota’s share could add 0.3–0.5¢/kWh to industrial delivery charges by 2028.
New Mexico: Solar-Coal Transition Economics
At publication, New Mexico’s industrial benchmark was 7.12¢/kWh; the current February 2026 EIA benchmark is 5.65¢/kWh. The state remains in energy transition. PNM (Public Service Company of New Mexico) is replacing the 847 MW San Juan Generating Station with a portfolio of solar, battery storage, and gas peakers. The transition economics remain favorable for many industrial users because:
- Solar PPAs in the I-25 corridor are clearing at $18–22/MWh (1.8–2.2¢/kWh) — among the cheapest in the nation.
- PNM’s 2026 rate case requests only a 2.8% increase for its Large Power service class, well below the national trend.
- The state’s Renewable Energy Act (REA) mandates 50% renewable energy by 2030, but the mandate cost is primarily allocated to residential and small commercial classes, subsidizing large industrial load.
Industrial Procurement Strategies
- Montana: Lock bilateral PPAs with BPA or WAPA allocations before SPP Markets+ integration reprices hydro. Target 5-year fixed terms at 5.5–6.5¢/kWh.
- North Dakota: Structure block-and-index contracts to capture negative nodal pricing during wind surplus events. Real-time co-optimization with on-site battery storage can push effective rates below 5¢/kWh.
- New Mexico: Negotiate behind-the-meter solar PPAs in the I-25 corridor. At $20/MWh solar + $8/MWh battery, a blended self-generation rate of 3–4¢/kWh is achievable for operations above 10 MW.
- Demand charges: All three states are tightening coincident peak (CP) penalties. Invest in automated demand response or battery arbitrage to shave peak demand charges, which can add 20–40% to the effective ¢/kWh rate for industrial loads with spiky demand profiles.
