Market Overview
Ozarks Electric is a member-owned, non-profit cooperative serving Arkansas and Oklahoma. Neither state offers retail electric choice to cooperative members, so C&I customers cannot select a competitive supplier. Rates are board-approved (Arkansas rates are reviewed by the Arkansas Public Service Commission). Wholesale power is supplied by AECC (Arkansas) and KAMO Power (Oklahoma).

Rate Recommendations by Use Case
Three-phase commercial facility with demand charges
Three-phase commercial accounts pay a per-kW demand charge set by the highest 15-minute interval on top of seasonal energy.
With demand priced on a single 15-minute peak, peak-shaving and load staggering have an outsized impact on the bill.
- Use MyOzarks demand tracking to find peak-setting events
- Stagger large motor/HVAC starts
- Shift flexible load to the off-peak season
Large commercial / industrial load
Large C&I accounts face energy plus a significant per-kW demand component and a facilities charge.
Demand and wholesale pass-through dominate the bill; the 2026 adjustment reflects a 5% AECC wholesale increase, so demand management directly offsets rising energy cost.
- Pull 15-minute interval data via Nectar for demand analysis
- Target the single monthly demand peak
- Confirm exact demand and facilities values in the Arkansas summary of rates
Energy team needing programmatic interval data
With no official public API, consultants should standardize on Nectar for authorized 15-minute interval and billing data.
Nectar's OAuth 2.0 flow and API deliver normalized 15-minute intervals and statements across many accounts, avoiding manual authorization delays — see docs.nectarclimate.com.
- Register with Nectar at docs.nectarclimate.com
- Use the interval endpoints for 15-minute data
- Reserve the open-source SmartHub downloader for personal use only
Fleet or workplace EV charging
Sites adding EV or fleet charging should enroll in the EV Charging Rate to capture reduced off-peak pricing and the charger rebate.
Charging between 10 p.m. and 5 a.m. avoids higher daytime/seasonal energy and qualifies for a Level 2 charger rebate up to $250.
- Schedule charging within the 10 p.m.-5 a.m. window
- Apply for the Level 2 charger rebate
- Use MyOzarks to verify off-peak charging behavior
Historical Rate Trends

For 2026, the cooperative announced an Arkansas increase of 2.03% effective June 1, 2026 (covering a 5% AECC wholesale increase) and an Oklahoma increase of 1.33% effective April 1, 2026 (covering a 2.5% KAMO Power increase). The small/three-phase commercial facilities charge and demand rate were held in the Arkansas adjustment.
June 1, 2026
Arkansas overall rates increased 2.03% to cover a 5% AECC wholesale power increase; about $2.84 more per month for an average residential account.
+2.03%April 1, 2026
Oklahoma overall rates increased 1.33% to cover a 2.5% KAMO Power wholesale increase; about $1.86 more per month for an average residential account.
+1.33%Overall trend: Gradual increases driven by wholesale power costs; the cooperative signals further adjustments are likely over the next several years.
Next expected change: Arkansas +2.03% effective June 1, 2026; Oklahoma +1.33% effective April 1, 2026. Future adjustments likely as wholesale costs rise.
Cost Optimization Strategies
Because commercial demand is set by the highest single 15-minute interval and base energy is seasonal, the biggest savings come from shaving 15-minute peaks, shifting load to off-peak months/hours, and using MyOzarks analytics to find waste.
Shave the 15-minute demand peak
For: Three-phase and large commercial/industrial accounts
Demand charges derive from the single highest 15-minute interval. Staggering equipment starts and using peak-shaving controls lowers the per-kW demand component of the commercial bill.
Shift usage to the off-peak season
For: All commercial and industrial accounts
Energy is priced higher in the peak season (May-October, $0.097320/kWh in AR) than off-peak (November-April). Shifting flexible production to off-peak months lowers energy cost.
Use MyOzarks energy analytics
For: All members
MyOzarks includes 15-minute usage analytics, disaggregation, and demand tracking. Reviewing these identifies inefficient end-uses and demand-setting events.
Optimize EV/fleet charging off-peak
For: Members with EV or fleet charging loads
The EV Charging Rate offers reduced pricing for charging between 10 p.m. and 5 a.m. daily, plus a charger rebate, ideal for fleet and workplace charging.
Take a free commercial energy audit
For: All commercial and public-sector accounts
Ozarks offers free energy audits for businesses and public-sector facilities to identify efficiency and demand reduction opportunities.

Frequently Asked Questions
How does my consultant pull 15-minute interval data for our Ozarks Electric accounts?▾
Ozarks does not offer a public API, but interval data is available through Nectar using OAuth 2.0 customer consent — see docs.nectarclimate.com. Members can also view 15-minute data directly in MyOzarks. A community tool, Electric Usage Downloader, works for personal automation only.
How is demand calculated for commercial billing?▾
Demand is based on the highest single 15-minute interval during the billing period, captured by the AMI meter. Commercial and three-phase accounts pay a per-kW demand charge on top of energy; manage your 15-minute peaks to control the bill.
Are Ozarks Electric rates seasonal?▾
Yes. Base rates use an off-peak season (November-April) and a peak season (May-October). In Arkansas, verified base energy is $0.087320/kWh for the first 1,000 kWh off-peak (over 1,000 kWh: $0.082320) and $0.097320/kWh in the peak season, with a $27/month customer charge.
Are rates changing in 2026?▾
Yes. Effective June 1, 2026, overall Arkansas rates increase 2.03% to cover a 5% wholesale increase from AECC; Oklahoma rates rise 1.33% effective April 1, 2026, to cover a 2.5% KAMO Power increase. Ozarks estimates roughly $2.84 more per month for an average Arkansas residential account.
Does Ozarks Electric offer Green Button or EDI?▾
Neither is currently documented. Green Button status is unclear (NISC holds a DOE grant), and there is no published EDI program. For structured commercial data, Nectar's API is the recommended path — see docs.nectarclimate.com.
