Rate Recommendations by Use Case

🏢

Mid-size commercial facility (50-100 kW)

Offices, retail, and light commercial in the Medium General Service band.

Recommended:
Medium General Service (MGS01)

MGS01 carries a moderate $3.88/kW demand charge and $0.05545/kWh energy; managing peak demand is the primary lever.

Tips:
  • Track 15-minute demand via the lookup tool
  • Stagger HVAC and equipment startups
  • Correct power factor to avoid kVAR charges
Est. monthly: Driven by peak kW; demand at $3.88/kW
🏭

Large commercial / institutional (100-400 kW)

Larger campuses, manufacturing, and institutional loads.

Recommended:
Large General Service (LGS01)

LGS01 adds a $1.34/kW load-size charge plus $4.72/kW demand; primary-voltage service unlocks an additional discount.

Tips:
  • Evaluate primary-voltage metering for the -1.5% / -$0.15/kW discount
  • Flatten demand peaks
  • Pursue efficiency rebates and on-bill financing
Est. monthly: Energy at $0.05049/kWh plus demand and load-size charges
⚙️

Very large / industrial load (400 kW+)

Industrial plants and 400 kW+ facilities on seasonal TOU pricing.

Recommended:
Extra Large General Service (XGS01)Industrial Service (IND01)

These classes use seasonal time-of-day energy rates and demand charges of $6.12-$6.23/kW, so off-peak load shifting compounds savings on both energy and demand.

Tips:
  • Shift production to off-peak and mid-peak windows
  • Avoid winter on-peak energy (highest seasonal rate)
  • Optimize power factor and take primary voltage
Est. monthly: Seasonal TOU energy plus $6.12-$6.23/kW demand

05

Cost Optimization Strategies

Because larger Flathead classes bill on demand and seasonal time-of-day energy, the biggest savings come from peak management and voltage-level optimization.

Shift load off peak

For: XGS01, IND01, and demand-billed MGS/LGS members

Demand charges of $3.88-$6.23/kW plus higher on-peak energy avoided

Move discretionary load out of peak windows to cut demand charges and capture lower off-peak/mid-peak seasonal energy rates on XGS and Industrial schedules.

Take service at primary voltage

For: MGS01, LGS01, XGS01, IND01

-1.5% of bill plus -$0.15/kW

Members metered at primary voltage receive a -1.5% total-bill discount and -$0.15/kW, which can offset the cost of owning transformation equipment.

Correct power factor

For: MGS01 and larger

Avoids $1.29 per kVAR billed

Avoid the $1.29/kVAR reactive power charge by maintaining good power factor with capacitor banks or VFDs.

Use efficiency rebates

For: All commercial members

Varies by measure

Apply for commercial efficiency rebates and on-bill financing to reduce both consumption and billed demand.

Frequently Asked Questions

How can a commercial member pull interval data for energy analysis?

Log in to SmartHub and use the Usage Explorer to download up to 14 months of Green Button (ESPI XML) interval data. For 15-minute demand specifically, use the public 15-Minute Demand Lookup Tool. For bulk or recurring exports, contact Energy Services at (406) 751-1834.

Does Flathead Electric support automated third-party data access (Green Button Connect or an API)?

No automated Green Button Connect My Data or public API is documented. Third parties such as energy managers or aggregators must arrange access directly with the co-op, typically via signed member authorization, or have the member download and forward Green Button files.

Which rate schedule applies to my business?

Schedules are sized by demand: Small General Service (under 50 kW), Medium General Service (50 to under 100 kW), Large General Service (100 to under 400 kW), Extra Large General Service (400 to under 1,000 kW), and Industrial Service (1,000 kW and above). Larger classes carry separate demand and load-size charges plus time-of-day energy pricing.

How do demand charges work for C&I members?

Medium and larger general-service classes bill a per-kW demand charge based on metered peak demand. Extra Large General Service and Industrial classes also use seasonal time-of-day energy rates (winter/summer on-, mid-, and off-peak), so shifting load off peak reduces both energy and demand costs.

Is there a discount for taking service at primary voltage?

Yes. Medium, Large, Extra Large General Service, and Industrial classes receive a Primary Voltage Delivery Discount of -1.5% of the total bill and -$0.15 per kW for members metered at primary voltage.
