Current Rate Schedules
PRVEPA publishes non-residential schedules effective January 1, 2025: General Service, Large General Service, Large Power Service (LP), Extra Large Power Service, and Bulk Power Service. The Large Power Service (LP) sheet is the most fully detailed publicly: a $3.00/day base charge, $10.25/kVA demand charge, and a 7.554-cent/kWh energy charge (7.354-cent/kWh all-electric, Dec-Mar), all subject to a monthly Power Cost Adjustment tied to a 90.216 mills/kWh base power cost. Larger classes (Extra Large Power, Bulk Power) follow similar demand-plus-energy structures with lower energy rates at higher voltage; exact figures are published on the cooperative's rate sheets.

Rate Recommendations by Use Case
Manufacturer / large industrial site (75-1,000 kVA)
Sites on Large Power Service should treat the kVA demand charge as the primary cost lever given the 50% ratchet.
At $10.25/kVA with a 50% ratchet, peak control and primary metering ($0.40/kVA discount) yield durable savings; the PCA passes through wholesale cost regardless of class.
- Pursue primary metering for the demand discount
- Implement peak-shaving controls on largest loads
- Request AMI interval data to validate the ratchet baseline
Mid-size commercial (retail, office, institutional)
Confirm whether General Service or Large General Service minimizes total cost as demand grows.
Crossing into a demand-based class can raise or lower total cost depending on load factor; review both rate sheets before committing.
- Model both classes at your actual load factor
- Watch demand creep toward the Large Power threshold
- Use portal usage data to track monthly peaks
Energy consultant / aggregator onboarding a Mississippi co-op account
Plan for manual data access since there is no API or Green Button.
PRVEPA requires account delegation or customer-supplied PDFs/exports; budget 5-15 business days for bulk interval data requests.
- Secure written customer authorization up front
- Request 15-minute AMI exports explicitly
- Set expectations on manual turnaround and possible fees
Historical Rate Trends
PRVEPA's published non-residential rate sheets carry an effective date of January 1, 2025. Because the cooperative is not PSC rate-regulated, changes are board-approved rather than docketed; month-to-month bill variation is driven mostly by the Power Cost Adjustment that floats with Cooperative Energy wholesale power costs.
January 1, 2025
Current non-residential rate sheets (General Service through Bulk Power) effective; Large Power energy charge set at 7.554-cent/kWh with $10.25/kVA demand.
n/aOverall trend: Generally tracks wholesale power costs from Cooperative Energy via the monthly PCA; demand and energy base rates updated periodically by the board.
Next expected change: Not publicly scheduled; monitor the PRVEPA Rates For Services page for new effective dates.
Cost Optimization Strategies
Because demand charges and the monthly Power Cost Adjustment dominate PRVEPA C&I bills, the highest-leverage strategies are peak-demand management, rate-class and metering optimization, and energy efficiency. Supplier shopping is not an option in Mississippi.
Peak demand management
For: Large Power, Extra Large Power, Bulk Power
Stagger large motor/HVAC starts and shave 15-minute peaks; the 50% demand ratchet means a single high peak inflates billing demand for up to 11 months.
Primary metering / voltage optimization
For: Large Power and above with own transformation
Take service at primary voltage to earn the $0.40/kVA demand discount and avoid transformer-loss adders.
All-electric winter provision
For: All-electric Large Power sites
Qualifying all-electric operations meeting efficiency requirements receive a reduced 7.354-cent/kWh energy charge Dec-Mar on the LP schedule.
Interval-data-driven efficiency
For: All C&I classes
Use AMI 15-minute data (via manual request or portal usage views) to find load anomalies and target efficiency upgrades that lower both energy and demand.
To implement these strategies, you need your 15-minute interval data. Learn how to download Pearl River Valley Electric Power Association interval data →
Frequently Asked Questions
Can a third-party energy consultant pull our facility's interval data automatically from PRVEPA?▾
No. PRVEPA has no Green Button, Share My Data, or public API. A consultant can be added as an authorized portal user (account delegation) or work from customer-supplied PDFs and usage exports. For 15-minute interval data, the customer must submit a manual request to PRVEPA (allow 10-15 business days; a fee may apply).
What rate schedules apply to commercial and industrial accounts?▾
PRVEPA publishes General Service, Large General Service, Large Power Service (LP, 75-1,000 kVA), Extra Large Power Service, and Bulk Power Service schedules. Large Power and above are demand-based (kVA demand charge plus energy charge plus a monthly Power Cost Adjustment). See the cooperative's published rate sheets for each class.
Does PRVEPA support EDI for invoices or payment remittance?▾
No EDI program is publicly documented. As a member-owned cooperative not rate-regulated by the Mississippi PSC, PRVEPA does not file tariffs that outline EDI capabilities. C&I customers needing EDI should contact Commercial/Industrial Customer Service to request a feasibility assessment.
How far back does billing and usage history go, and how do we get bulk data?▾
The SmartHub portal typically retains 12+ months. For older or bulk data, call 855-2PRVEPA or mail the Billing Department with the account number and date range; expect 5-15 business days and a possible compilation charge for large interval extracts.
Can we shop for a competitive electricity supplier for our Mississippi facilities?▾
No. Mississippi is a regulated, non-choice state. PRVEPA members buy bundled electric service from the cooperative; there is no competitive retail supplier market. Cost management focuses on demand management, rate-class optimization, and efficiency rather than supplier switching.
