Current Rate Schedules
KU electric rates are set by the Kentucky Public Service Commission. In Case No. 2025-00113, KU and LG&E reached a settlement approved by the KPSC in February 2026, with new base rates following interim rates effective around January 1, 2026 and a base-rate 'stay-out' until August 1, 2028. The settlement raised the average residential bill ~6.54% (to $142.30/mo at 1,085 kWh) and migrates Power Service demand billing from kW to kVA with a time-differentiated 3-tier maximum-load charge. Exact per-kWh and per-kVA C&I charges are published in the KU electric rate tariff (dated April 2, 2026).

Rate Recommendations by Use Case
Demand-heavy industrial facility
Pull 15-minute MV-Web data, target coincident-peak reduction, and evaluate TODS/TODP to shift load off-peak — demand charges are now trending to kVA-based 3-tier billing.
On demand-metered schedules the maximum-load charge dominates the bill; interval-data-driven peak management yields the largest savings.
- Request MV-Web access and export CSV
- Identify and shave coincident peaks
- Model kVA vs kW impact after the 2025-00113 changes
Multi-site commercial portfolio
Automate data collection across sites with Green Button Connect My Data and benchmark per-site kWh and demand to spot outliers.
CMD's OAuth API delivers 15-minute interval + billing data within 4-6 hours, ideal for portfolio analytics.
- Use a Green Button certified platform
- Authorize CMD per account in My Account
- Compare load factor across sites
Energy consultant / aggregator
Combine Green Button CMD for interval data with EDI 810 for billing automation across enrolled customers.
CMD covers usage; EDI 810 (via ECLynx/Xebec) automates monthly invoices for accounting integration.
- Get Green Button certified
- Use Xebec for EDI conversion to your format
- Delegate MV-Web access where CMD is not set up
Demand response participant
Enroll large flexible load in Business Demand Response to earn curtailment incentives, using the 5-minute portal feed to verify reductions.
Facilities ≥200 kW that can curtail ≥50 kW earn incentive payments while gaining a finer-grained 5-minute data feed.
- Confirm ≥200 kW base demand and DSM participation
- Document a 50+ kW curtailment plan
- Track dispatch performance in the portal
Historical Rate Trends
KU's most recent base-rate change came in Case No. 2025-00113. Interim rates took effect around January 1, 2026 and the KPSC approved the settlement in February 2026, with a base-rate 'stay-out' until August 1, 2028. The average residential customer (1,085 kWh) rose $8.73/month, from $133.57 to $142.30 (+6.54%); Power Service demand billing migrates from kW to kVA on a time-differentiated 3-tier basis.
January 1, 2026
Case No. 2025-00113 settlement (KPSC-approved Feb 2026): average residential bill +6.54% ($133.57 → $142.30 at 1,085 kWh); Power Service demand migrates kW→kVA with a 3-tier time-differentiated maximum-load charge.
+6.54%Overall trend: Upward — 6.54% average residential increase under the 2025-00113 settlement.
Next expected change: Base-rate stay-out through August 1, 2028; adjustment-clause (fuel/environmental/DSM) updates continue between rate cases.
Cost Optimization Strategies
Because KU rates are regulated and bundled, C&I cost management focuses on demand reduction, time-of-day load shifting, rate-schedule selection, and demand-response incentives — all informed by KU's 15-minute interval data.
Manage peak demand (kW/kVA)
For: Demand-metered C&I (PS, TODS, TODP, RTS)
Use My Meter / MV-Web interval data to identify and shave coincident peaks, lowering the maximum-load (demand) charge that drives much of a PS/TODS/TODP/RTS bill — now increasingly kVA-based.
Shift load off-peak (time-of-day)
For: Time-of-day C&I schedules
On TODS/TODP/RTS, move flexible load out of on-peak windows to cut both time-differentiated energy and the highest demand tier.
Enroll in Business Demand Response
For: C&I with ≥200 kW base demand
Curtail ≥50 kW during dispatch events for incentive payments; uses a 5-minute interval feed for verification.
Right-size rate schedule
For: All C&I
Compare GS vs. PS vs. TOD options against your load factor and demand profile using interval data to select the lowest-cost eligible schedule.
To implement these strategies, you need your 15-minute interval data. Learn how to download Kentucky Utilities interval data →
Frequently Asked Questions
How does a C&I customer get 15-minute interval data from KU?▾
Demand-metered C&I accounts (RTS, TODP, TODS) request MV-Web access from their KU Account Manager (800-981-0600), then export 15-minute interval data — kWh, kW/kVA, power factor — to CSV. All accounts can also use Green Button Download My Data (XML) from My Meter.
Can a third party pull KU usage data automatically?▾
Yes. Green Button Connect My Data provides OAuth 2.0-authorized API access to 15-minute interval and billing data (updated within 4-6 hours). Alternatively, the customer can delegate MV-Web access or add the third party as a Joint Account Holder.
Which rate schedules apply to KU commercial and industrial customers?▾
KU C&I schedules include General Service (GS), Power Service (PS), Time-of-Day Secondary/Primary (TODS/TODP), Retail Transmission Service (RTS), Fluctuating Load Service (FLS), and the time-of-day energy/demand options (GTODE/GTODD). Demand-metered schedules qualify for MV-Web interval data.
How does KU bill demand charges for Power Service customers?▾
Under the 2025-00113 settlement, KU is migrating Power Service (PS) demand billing from kW to kVA and from a seasonal maximum-load charge to a time-differentiated 3-tier maximum-load charge, aligning PS with the TODS/TODP/RTS structure. Exact per-kVA and per-kWh figures are in the KU electric rate tariff.
Does KU offer EDI billing for commercial accounts?▾
Yes — KU supports ANSI X12 4010 EDI 810 invoices with 997 acknowledgments, administered via ECLynx with Xebec Data Corp as testing/outsourcing provider. Enrollment requires a Trading Partner Agreement and Account List Form plus 2-3 cycles of parallel testing.
