Current Rate Schedules
Cheyenne Light, Fuel & Power (d/b/a Black Hills Energy) serves Cheyenne under Wyoming PSC Tariff No. 13, with current base rates set by the March 2023 rate case settlement — the first since 2014. Commercial customers fall into three classes by demand and voltage: Commercial Service (under 25 kW), Secondary General Service (demand-metered at secondary voltage), and Primary General Service (primary voltage). All schedules carry Power Cost Adjustment (PCA), Transmission Cost Adjustment Mechanism (TCAM), and Demand Side Management riders. Billing demand on general service schedules is the maximum 15-minute integrated kW of the month. A Large Power Contract Service schedule serves loads of 5,000 kW or more (e.g., data centers) under contract with directly assigned capacity resources.
Effective: March 1, 2023 · Full Tariff Book →
| Schedule | Type | Applicability | Structure | Rate |
|---|---|---|---|---|
| Schedule C — Commercial Service | commercial | Customers with demands under 25 kW taking lighting and power at secondary distribution voltage. | $25.00/month service and facility charge; base delivery rate of $0.07884/kWh plus base energy rate of $0.03362/kWh and riders — an all-in volumetric rate of roughly $0.1426/kWh per the rate summation sheet. No demand charge. | ~$0.143/kWh all-in |
| Schedule SG — Secondary General Service | commercial | Demand-metered lighting and power customers at secondary voltage — typically 25 kW and above. | $140.00/month service and facility charge; capacity charge of $24.00/kW of billing demand (max 15-minute integrated kW); volumetric charges totaling roughly $0.0729/kWh all-in including base delivery ($0.01149), base energy ($0.03362), PCA, TCAM, and DSM riders. | ~$0.073/kWh all-in+ $24.00/kW of billing demand |
| Schedule PG — Primary General Service | industrial | Large lighting and power customers taking delivery at primary voltage and owning transformation. | $235.00/month service and facility charge; capacity charge of roughly $20.50-$21/kW; hours-use volumetric blocks (~$0.0550/kWh for the first 600 kWh per kW of demand, ~$0.0484/kWh beyond) including riders. Lower unit costs reflect primary-voltage delivery. | ~$0.048-$0.055/kWh all-in+ ~$20.50/kW of billing demand |

Rate Recommendations by Use Case
Portfolio billing data collection
Pull up to 2 years of billing history per account using the portal's Export Billing Data feature.
The Excel export is the only structured, self-service data channel Black Hills Energy Wyoming offers — faster and cleaner than PDF bill scraping.
- Export Excel rather than PDF for downstream processing
- Set the date range to the full 2-year maximum on first pull
- Enable bill alerts so statements are captured on cycle
Third-party / consultant data access
Use the Customer Information Release Form to get the utility to release billing data to an authorized consultant or energy manager.
With no native API or Green Button, the signed release form is the only utility-sanctioned third-party path.
- Request the form via 888-890-5554 and name the third party precisely
- Specify the exact data scope and time period in the request
- For interval data, escalate to Regulatory Affairs (605-721-2348) — it lives in the Siemens MDMS and isn't released by default
Interval data strategy for large facilities
Plan around the 13-month interval retention window and pursue access through regulatory or direct channels.
15-minute data exists in the EnergyIP MDMS but is not customer-facing; the Wyoming PSC (307-777-7427) or SD PUC (605-773-3201) can clarify tariff data-access rights.
- Ask customer service explicitly whether interval data can be shared under customer authorization
- Document requests in writing to build a record for PUC inquiries
- Watch for future Green Button CMD advocacy opportunities in state dockets
Automated data integration for energy software
Use Nectar for programmatic access to Black Hills Energy Wyoming data in any data pipeline.
The utility offers no developer portal, API, or ESPI of its own — Nectar provides API access to its billing data (docs.nectarclimate.com), with credential-based portal exports as the fallback.
- Integrate via Nectar's API — see docs.nectarclimate.com
- Standardize on the portal's Excel billing export as a fallback
- Maintain signed release forms per account for any utility-released data
Cost Optimization Strategies
CLFP's rate design concentrates cost in capacity charges — $24/kW on Secondary General Service is among the steeper demand charges in the region — while volumetric rates on demand-metered schedules are comparatively low. That makes 15-minute peak management, voltage-level election, and rider tracking the highest-value levers for Cheyenne C&I customers.
Capacity charge management
For: Secondary and Primary General Service customers
Billing demand is the maximum 15-minute integrated kW of the month, billed at $24.00/kW on Schedule SG (~$20.50/kW on PG). Sequence motor and HVAC starts, interlock large loads, and deploy demand-limiting controls — a single coincident spike costs all month.
AMI interval data analysis
For: All demand-metered commercial customers
CLFP's AMI network records 15-minute interval data on ~39,000 smart meters. Request your interval history through Black Hills Energy customer service and use it to pinpoint the exact intervals setting your capacity charge before investing in controls.
Voltage level and schedule election
For: Large commercial and industrial customers
Large loads should compare Secondary General Service against Primary General Service — PG's lower capacity charge and energy blocks reward customers who can take primary-voltage delivery and own transformation. Loads of 5,000 kW+ should evaluate Large Power Contract Service terms.
Rider tracking (PCA, TCAM, DSM)
For: All customers; material for high-volume accounts
The Power Cost Adjustment, Transmission Cost Adjustment Mechanism, and DSM charges adjust volumetric rates over time. Trend these riders separately from base rates for budgeting — they can move materially between Wyoming PSC filings.
Demand-side management programs
For: All commercial and industrial customers
CLFP funds efficiency programs through the DSM rider — customers should claim the rebates they're already paying for. Lighting, HVAC, and motor upgrades cut both the energy blocks and the 15-minute peaks behind the capacity charge.

Frequently Asked Questions
How do C&I customers get billing data from Cheyenne Light Fuel & Power (Black Hills Energy)?▾
Log into My Account at https://www.blackhillsenergy.com/my-account/, open Billing > History, and use Export Billing Data to download up to 2 years of statements and payment history as Excel (.xlsx) or PDF. That export is the only structured self-service data channel the utility offers.
Is 15-minute interval data available for commercial accounts?▾
The utility's ~39,102 AMI meters record kWh at 15-minute intervals into a Siemens eMeter EnergyIP MDMS, with roughly 13 months retained. However, interval data is not documented as downloadable by customers — the portal shows monthly usage graphs only. To pursue interval data, ask customer service (888-890-5554) whether it can be released under customer authorization, or escalate to Regulatory Affairs at 605-721-2348.
Does Black Hills Energy Wyoming support Green Button or a usage API?▾
Not natively. Neither Green Button Download My Data nor Connect My Data is implemented, and there is no utility ESPI interface or developer portal. Nectar provides API access to Black Hills Energy Wyoming billing data — see docs.nectarclimate.com. Otherwise, plan for credential-based portal exports and manual authorization workflows.
How can an energy consultant or aggregator access a customer's data?▾
Through a signed Customer Information Release Form: the customer requests the form from customer service (888-890-5554), names the third party, specifies the data and time period, and submits the signed authorization. The utility then releases available data directly to the third party.
Can Wyoming commercial customers shop for a competitive electricity supplier?▾
No. Wyoming and South Dakota are fully regulated states with no retail electric choice. Cheyenne Light, Fuel & Power d/b/a Black Hills Energy is the bundled supplier and distributor, with rates set by the Wyoming PSC (Tariff No. 13) and the South Dakota PUC.
Does the utility support EDI for commercial billing?▾
No. There is no documented support for 810, 814, 820, 824, 867, or 997 transaction sets, no trading partner enrollment, and no VAN relationships. Commercial customers needing electronic billing data should use the portal's Excel billing export instead.
