Current Rate Schedules
Farmington Electric Utility System (FEUS), the City of Farmington's municipal utility serving San Juan and Rio Arriba counties, adopted a four-phase rate plan (2022-2025); Phase IV rates took effect July 1, 2025. The design shifts revenue toward fixed System Infrastructure Charges and demand charges while stepping energy rates down each phase. Non-residential classes split by load: Small General Service (<40 kW / <15,000 kWh), Medium General Service (40-500 kW), Large General Service (500-4,000 kW), and Bulk Power Service (4,000+ kW at 69/115 kV). Demand-billed classes use the peak 15-minute interval with a 75% twelve-month ratchet and class minimum demands. A Power Cost Adjustment varies rates around a $0.04465/kWh base power supply index. Full tariffs are in the city's Document Center.

Rate Recommendations by Use Case
Commercial billing data collection
Pull bills monthly from the Relay Web portal and request older history through customer service.
The portal holds 12+ months online while customer service can reach records back to 1996 — useful for long-baseline rate and usage analysis.
- Register the account once and enable paperless billing for consistent capture
- Request pre-portal history via (505) 599-1353 when building multi-year baselines
- Track the Energy Charge, Infrastructure Charge, and Power Cost Adjustment separately
Third-party / consultant access
Run an LOA-first workflow and plan for manual, monthly-granularity data delivery.
FEUS has no API or formal program; a customer-signed Letter of Authorization routed through Customer Service or Business Operations is the only sanctioned path.
- Specify data types, accounts, time period, and authorization duration in the LOA
- Engage Business Operations (Sheree Wilson, 505-599-8311) for commercial requests
- Expect security/confidentiality terms before data release
Interval data planning
Track the Enhanced Meters rollout — real-time usage access is promised but not yet delivered.
The 2024-2030 AMI deployment is the prerequisite for any interval visibility; granularity and portal features remain unannounced.
- Confirm meter installation status for each facility via (505) 599-1353
- Use submetering if interval data is needed before the rollout reaches you
- For programmatic access discussions, contact Regulatory Compliance (Linda Jacobson-Quinn, 505-599-1163)
Automated data integration for energy software
Classify FEUS as a manual-collection utility with no aggregator coverage.
No Green Button, ESPI, EDI, or aggregator integration exists; credentialed portal access and PDF parsing are the practical options.
- Store portal credentials securely with customer consent
- Parse PDF bills into structured data downstream
- Monitor the Enhanced Meters page for future portal data features
Cost Optimization Strategies
FEUS's 2022-2025 phased redesign deliberately moved cost into fixed infrastructure charges and per-kW demand charges while cutting energy rates — so C&I savings now hinge on demand behavior, ratchet management, power factor, and contract elections rather than raw kWh reduction alone. The PCA passes wholesale power cost variances around a $0.04465/kWh index.
15-minute peak and ratchet management
For: Medium General Service, Large General Service, and Bulk Power accounts
Billing demand on Medium/Large/Bulk classes is the highest of the current 15-minute peak or 75% of the maximum from the preceding 11 months — one spike sets a floor for a year. Stagger equipment starts, interlock large loads, and use FEUS interval data to keep peaks controlled.
Power factor correction (Bulk Power)
For: Bulk Power and large industrial customers with motor-heavy loads
Bulk Power long-term service bills $0.75/kVar (Phase IV) on reactive demand exceeding 0.33 times kW demand. Capacitor banks at large motor and compressor installations eliminate the kVar penalty permanently and reduce losses.
Long-term bulk contract election
For: Industrial loads of at least 4,000 kW with stable multi-year operations
Qualifying 4,000 kW+ loads at 69 kV or higher can elect Bulk Power Long Term (Rate No. 21): $7.75/kW versus $10.75/kW and $0.03750/kWh versus $0.04393/kWh at Phase IV — roughly 28% lower demand cost in exchange for contract commitment.
Rate class boundary management
For: Commercial accounts near class thresholds
FEUS reclassifies accounts that cross thresholds (40 kW/15,000 kWh; 500 kW/265,000 kWh; 4,000 kW) for three months in a 12-month period. Accounts near boundaries should model both classes — the fixed-charge jumps ($150 to $1,250 to $2,500) can dominate for marginal loads — and manage demand to stay in the favorable class.
PCA tracking and efficiency stacking
For: All commercial and industrial accounts
Rates float with the Power Cost Adjustment around the $0.04465/kWh power supply index, and FEUS's energy rates stepped down each phase while fixed charges rose. Efficiency still returns the full energy rate plus PCA, but projects should be evaluated against Phase IV energy prices — demand-reducing measures (HVAC controls, VFDs) now out-earn pure kWh measures.

Frequently Asked Questions
How do commercial customers get billing data from Farmington Electric Utility System?▾
Register the account on the Relay Web portal at https://utilities.fmtn.org/webpay using the utility account number from a bill. The dashboard shows billing history, usage information, and downloadable PDF bills, with 12+ months online. For older records — FEUS retains data back to at least 1996 — call Customer Service at (505) 599-1353.
Does FEUS offer interval or smart meter data?▾
Not yet. The Enhanced Meters AMI rollout began in January 2024 on a roughly 6-year timeline. FEUS promises real-time usage access through the portal once meters are deployed, but granularity (15-minute, hourly, daily), formats, and timing are unspecified. Check installation status for your facility via (505) 599-1353 and use submetering if interval visibility is needed sooner.
Can a third-party consultant or platform access FEUS customer data?▾
Only via a manual Letter of Authorization. There is no API, Green Button, ESPI, or aggregator integration. The customer requests the LOA process from Customer Service (505-599-1353), completes the form naming the third party, data types, duration, and purpose, and FEUS handles delivery — typically periodic extracts at monthly granularity, sometimes under confidentiality terms.
Does FEUS support EDI for commercial billing?▾
No EDI program is documented — no ANSI X12 transaction sets, trading partner enrollment, or VAN partnerships. Businesses needing EDI should contact Regulatory Compliance (Linda Jacobson-Quinn, 505-599-1163) or Business Operations (Sheree Wilson, 505-599-8311) with their required transaction types and volumes to discuss feasibility.
Where are FEUS rate schedules published?▾
All rate schedules and tariffs live in the City of Farmington Document Center (farmingtonnm.gov/DocumentCenter/), including 2025 Residential, Small General Service, and Commercial rates as PDFs. Bills consist of an Energy Charge (kWh), System Infrastructure Charge, and Power Cost Adjustment. As a municipal utility, rates are set by the city and there is no retail supplier choice in New Mexico.
