Market Overview
Kenergy operates in Kentucky's regulated market with no retail supplier choice. Distribution rates are PSC-approved and wholesale power is sourced via Big Rivers Electric Corporation. Large industrial smelter loads buy power on the open market through Kenergy under PSC-approved contracts.

Current Rate Schedules
Rates below are from Kenergy's published rate page (excluding adjustment clauses, taxes and fees). Three-phase demand service is tiered by load and load factor. The largest industrial loads (e.g., Century Aluminum smelters) are served under separately PSC-approved market-priced contracts rather than these schedules.

Rate Recommendations by Use Case
Mid-size three-phase commercial site
Three-phase C&I loads up to 1,000 kW fall under the 0-1,000 kW demand schedule with declining-block energy.
Declining-block energy rewards higher consumption per kW; the $5.78/kW demand charge makes peak management the primary lever.
- Track monthly peak kW and shave coincident peaks
- Pursue the $0.65/kW primary-meter discount if you can own transformation
Large high-utilization industrial
Loads above 1,000 kW running steadily benefit from the high-load-factor schedule.
Energy blocks drop to ~$0.047-0.054/kWh above 50% load factor, offsetting the $12.70/kW demand charge for round-the-clock operations.
- Maintain load factor above 50% to stay on the favorable schedule
- Model demand vs energy trade-off before committing
Large intermittent / low-utilization industrial
Variable loads above 1,000 kW with sub-50% load factor use the low-load-factor schedule.
A lower $7.15/kW demand charge suits spiky operations, though energy blocks are higher ($0.066-0.075/kWh).
- Compare against the high-LF schedule as utilization rises
- Flatten load profile where feasible to shift schedules
Smelter-scale dedicated load
Very large loads (e.g., aluminum smelters) negotiate PSC-approved market-priced power contracts.
Open-market pass-through pricing via Kenergy/Big Rivers can beat the standard tariff for multi-MW continuous loads, as established for Century Aluminum.
- Engage Kenergy commercial services and review existing PSC contract filings
- Plan for market price exposure and hedging
Historical Rate Trends
As a Big Rivers member cooperative, Kenergy's retail rates move primarily with PSC-approved Big Rivers wholesale rate changes and monthly fuel/adjustment clauses. The tariff index on the KY PSC site was last updated February 2026.

Cost Optimization Strategies
C&I cost control at Kenergy centers on demand management, load-factor improvement and capturing the primary-meter discount, with the largest loads negotiating market-priced contracts.
Improve load factor
For: Large three-phase industrial
Above 1,000 kW, qualifying for the high-load-factor schedule cuts energy block rates substantially (to ~$0.047-0.054/kWh) in exchange for a higher demand charge.
Manage peak demand
For: All demand-metered C&I
Demand charges run $5.78-$12.70/kW. Staggering equipment and shaving coincident peaks directly lowers the kW billing determinant.
Take the primary-meter discount
For: Demand-metered C&I able to own equipment
Owning transformation and metering at primary voltage earns a $0.65/kW credit.
Negotiate market-priced contracts for very large loads
For: Smelter-scale dedicated industrial
Smelter-scale loads can pursue PSC-approved market pass-through arrangements rather than the standard demand tariff.

Frequently Asked Questions
How does a C&I customer at Kenergy get historical usage and billing data?▾
Log in to SmartHub for self-service bills and daily usage, or contact Commercial & Industrial Services (ciservices@kenergycorp.com, 1-800-844-4832) for a billing review or custom CSV/PDF report covering longer periods.
Can an energy consultant pull our Kenergy data automatically?▾
No automated feed or API exists. The practical path is a signed Letter of Agency submitted to Commercial & Industrial Services, after which Kenergy emails CSV or PDF exports, typically within 5-10 business days.
Does Kenergy support 15-minute interval data?▾
AMI meters capture interval data, but SmartHub only exposes daily usage to customers. Sub-daily interval extracts must be requested manually from member services and may not be available in self-service formats.
How are very large industrial loads like Century Aluminum handled?▾
Large smelter loads (Century Aluminum's Hawesville and Sebree facilities) are served under PSC-approved market-priced power contracts via Kenergy and Big Rivers, not the published retail tariff. Large industrial customers negotiate individual contract-based arrangements.
Does Kenergy support Green Button or EDI?▾
Green Button Download may be present in SmartHub but is not advertised, and Connect My Data is not implemented. EDI is undocumented; high-volume C&I customers should inquire directly with Commercial & Industrial Services.
