Joe Wheeler Electric Membership Corporation Rate Schedule Comparison
| Schedule | Type | Rate | Best For |
|---|---|---|---|
| General Power GSA-GSC | Commercial | Customer charge + per-kWh energy (+ demand on GSB/GSC); monthly TVA fuel adjustment | Offices, retail, and small-to-mid commercial loads |
| General Power GSD | Commercial/Industrial | Customer charge + energy + demand charges | High-demand commercial and light industrial facilities |
| Manufacturing MSB/MSC/MSD | Industrial | Demand + energy charges (distribution voltage) | Manufacturing and processing operations |
| Transmission TGSA/TDMSA/TDGSA | Industrial | Transmission-level demand + energy charges | Very large industrial loads served at transmission voltage |
Market Overview
JWEMC is a TVA distributor in a fully regulated, bundled market. It buys all power wholesale from TVA and resells under TVA-approved retail schedules. Alabama has no retail electric choice for any customer class.

Current Rate Schedules
Joe Wheeler EMC publishes monthly C&I rate schedule PDFs derived from TVA wholesale rates. General Power schedules GSA-GSD cover general commercial loads by size, while Manufacturing/Transmission schedules (MSB-MSD, TGSA, TDMSA, TDGSA) cover larger industrial loads. Schedules carry a customer charge plus energy and (for larger schedules) demand components, adjusted monthly via the TVA fuel/Total Monthly Fuel Cost mechanism. Per-unit dollar values are published only in monthly image-based PDFs; consult the linked schedule PDF for current figures.

Rate Recommendations by Use Case
Mid-size commercial facility (office/retail)
General Power schedules fit most commercial loads; manage demand to control GSB/GSC charges.
These schedules balance customer charge, energy, and demand for typical commercial demand profiles.
- Track 15-minute peaks via a manual interval request
- Shift HVAC/equipment cycling to flatten demand
Manufacturing / industrial plant
Manufacturing schedules (MSB-MSD) or transmission schedules apply based on demand and service voltage.
Demand-based manufacturing and transmission schedules price large, steady loads more efficiently than general power schedules.
- Evaluate transmission-voltage service if load justifies it
- Pursue TVA electrification incentives
Energy manager needing usage data
Plan for manual data acquisition: there is no Green Button or API.
JWEMC has no programmatic access, so build workflows around customer-authorized manual exports.
- Request 15-minute interval exports in writing
- Allow 2-4 weeks for fulfillment
- Capture portal/PDF bills monthly for benchmarking
Historical Rate Trends
JWEMC updates its C&I schedules monthly to reflect TVA wholesale rate and fuel cost changes; the cooperative posts separate PDFs for each month (e.g., May 2026 and June 2026).
June 1, 2026
June 2026 monthly C&I schedule revision reflecting TVA wholesale/fuel adjustment.
Varies monthly (TVA fuel adjustment)Overall trend: Rates move month to month with TVA's Total Monthly Fuel Cost and periodic TVA wholesale rate adjustments rather than discrete annual rate cases.
Next expected change: Next monthly schedule posting (following June 2026).
Cost Optimization Strategies
Because rates are TVA pass-through with demand charges on larger schedules, C&I savings come primarily from demand management, schedule selection, and TVA-funded efficiency incentives rather than supplier shopping (which is unavailable).
Demand (kW) management
For: Commercial and industrial accounts on demand-billed schedules
Stagger equipment startups and shift peaks to reduce billed demand on GSB/GSC/GSD and manufacturing schedules.
Schedule optimization
For: All C&I accounts
Confirm with JWEMC engineering that the account is on the lowest-cost applicable schedule for its demand and voltage.
TVA efficiency/electrification incentives
For: Commercial and industrial members
Use the Incentives for Electric Technologies program for rebates on efficient equipment and electrification.

Frequently Asked Questions
Can a C&I customer get 15-minute interval data from Joe Wheeler EMC?▾
The AMI meters record 15-minute intervals utility-side, but JWEMC does not provide self-service interval downloads, Green Button, or an API. A commercial customer can request raw interval data by calling (256) 552-2300 and asking the engineering department; format, timeline, and any fees are determined case-by-case.
Does Joe Wheeler EMC support Green Button or any data API for energy managers?▾
No. JWEMC is not on the Green Button Alliance directory and offers no ESPI/Connect My Data, REST API, or developer portal. Third-party energy managers must use a manual, customer-authorized process for billing or usage data.
Can my consultant or aggregator pull our usage data directly?▾
Not automatically. There is no formal third-party program. The customer must authorize the third party in writing with JWEMC, after which data is delivered manually at the cooperative's discretion. Plan for 2-4 weeks and expect file-based delivery rather than API feeds.
Can a commercial account in JWEMC territory shop for a competitive electricity supplier?▾
No. Alabama is a fully regulated state with no retail electric choice, and JWEMC resells TVA wholesale power. All C&I accounts take bundled service under the cooperative's TVA-aligned rate schedules; there is no supplier shopping.
Which rate schedule applies to a commercial or industrial account?▾
General Power schedules GSA, GSB, GSC, and GSD apply to general commercial loads (graduated by demand/size), while Manufacturing Service schedules (MSB, MSC, MSD) and Transmission/Distribution schedules (TGSA, TDMSA, TDGSA) apply to larger industrial and manufacturing loads. The applicable schedule depends on demand level and metering; contact the JWEMC engineering department to confirm.
