Flathead Electric Cooperative (Montana), Administrative Policy E&O 337 High Density Loads
Large-load tariff for data centers: what is on file, the terms the filings state, and where each fact comes from. Terms a filing does not state are marked, never guessed.
StatusApproved Last reviewed 2026-10-14
Applies atNo MW trigger: any load with an energy use intensity of 250 kWh per square foot per year or more, regardless of size
What the filing saysIN EFFECT since November 25, 2024 (a cooperative board policy, not a PUC-approved tariff). A high-density load pays a one-time per-kW Upfront Capacity Charge on its total designed load before construction starts (the dollar rate is in the cooperative's service-fee schedule, not read), plus all line extension costs and upgrades back to the distribution substation. Loads over 1,000 kW also fall under the industrial line extension policy. Unauthorized use above the designed load is charged a fee. Multiple locations are not aggregated unless a power sales contract provides for it.
