Jackson Energy Authority (JEA) Rate Selection Guide
Jackson Energy Authority (JEA) is a municipal public power utility serving roughly 38,700 electric customers in Jackson, Tennessee — one of the few US utilities delivering electric, gas, propane, water, wastewater, and broadband from a single company. Commercial demand is recorded in 30-minute intervals on Tantalus fiber-connected smart meters, but JEA offers no Green Button, EDI, or API access, so C&I data access runs through the customer portal and direct arrangements with the utility.
Market Overview
Tennessee is a fully regulated market with no retail supplier choice. JEA serves as the vertically integrated municipal distributor for Jackson and Madison County, supplied by TVA. Rate schedules document 30-minute demand measurement but no data-access mandates apply to municipal utilities in Tennessee.

Current Rate Schedules
Jackson Energy Authority is a TVA local power company, so its electric rates mirror TVA's wholesale structure: seasonal pricing (Summer, Winter, Transition periods), a TVA Fuel Cost Adjustment (FCA) layered onto base energy rates, and demand metered as the highest 30-consecutive-minute average each month. Commercial customers under 5,000 kW take Schedule GSA (three size tiers: GSA1 ≤50 kW, GSA2 50–1,000 kW, GSA3 >1,000 kW); 5,000–15,000 kW loads take GSB; manufacturing service schedules (MSA/MSB/MSD/SMS) cover larger industrial contract demands; and TGSA offers time-of-use pricing for 1,000–5,000 kW loads. Billing demand carries a 30% ratchet against the highest demand in the prior 12 months. Optional rates, incentives, and economic development credits are available through JEA's Economic and Industrial Development office (731-422-7325).

Rate Recommendations by Use Case
Manufacturing plants and large industrial loads (>1 MW)
Jackson's manufacturing base — food processing, automotive suppliers, and distribution along the I-40 corridor — typically lands on GSA3, TGSA, or the manufacturing service schedules depending on contract demand.
TGSA splits demand into on-peak ($9.48/kW summer) and maximum ($6.14/kW) components versus GSA3's flat $14.25/kW — plants that can hold on-peak demand down through shift scheduling or process staging often save under TOU, and off-peak energy runs ~$0.026/kWh below on-peak in summer.
- Model 12 months of 30-minute interval data under both GSA3 and TGSA before electing TOU — the 30% demand ratchet makes a single bad month expensive
- Watch the 2,500 kW threshold: demand above the higher of 2,500 kW or contract demand triggers doubled excess-demand charges
- Engage JEA Economic and Industrial Development (731-422-7325) about TVA incentive riders and economic development credits before expansions
Mid-size commercial: grocery, healthcare, schools (50–1,000 kW)
Hospitals, schools, grocery stores, and larger retail in Madison County fall on GSA2, where the first 50 kW of demand is free but every kW above costs $14–15.
GSA2's declining-block energy means tail-block kWh cost only $0.08572 while demand above 50 kW costs $15.40/kW in summer — the bill is demand-dominated, so peak management beats consumption cuts for most of these loads.
- Stagger HVAC and refrigeration compressor starts to flatten the 30-minute interval that sets billing demand
- Track the 12-month demand ratchet — billing demand never falls below 30% of your annual peak, so one summer spike echoes for a year
- Sites approaching 1,000 kW should evaluate whether GSA3's lower tail energy rate ($0.08955 flat) offsets full first-kW demand billing
Small commercial and institutional accounts (≤50 kW)
Shops, churches, offices, and restaurants under 50 kW take GSA1 — a simple energy-only rate with no demand charge.
At ~$0.136/kWh all-in, GSA1 is consumption-driven: efficiency upgrades translate dollar-for-dollar. But exceeding 50 kW demand or 15,000 kWh in any month reclassifies the account to GSA2, adding demand billing.
- Stay alert near the 15,000 kWh/month and 50 kW boundaries — crossing either moves you to GSA2 with demand charges
- Prioritize lighting and HVAC efficiency since every kWh saved avoids the full ~$0.136 rate
- Ask JEA about TVA EnergyRight commercial efficiency programs and incentives
Cost Optimization Strategies
With demand set by the single highest 30-minute interval, JEA C&I customers save most by flattening peaks and reviewing time-of-day rate eligibility with the utility.
Manage 30-minute peak demand
For: Commercial/industrial demand-metered accounts
Peak demand is calculated from the highest 30-minute interval in the billing period. Staggering large equipment starts and shifting discretionary load away from facility peaks directly reduces the demand component of the bill.
Request interval data for load analysis
For: Large C&I facilities
Raw 30-minute demand data is not self-service downloadable, so request a custom export through JEA Economic Development (731-422-7325) to identify which intervals set monthly peaks before investing in load shifting.
Evaluate time-of-day rates and TVA programs
For: Commercial accounts with flexible schedules
Discuss time-of-use options, load control, and TVA energy efficiency programs with JEA to align operating schedules with lower-cost periods.
To implement these strategies, you need your 15-minute interval data. Learn how to download Jackson Energy Authority (JEA) interval data →
Frequently Asked Questions
How do C&I customers get interval data from Jackson Energy Authority?▾
JEA records commercial/industrial demand in 30-minute intervals on Tantalus fiber-connected smart meters, but the portal only shows aggregated daily and monthly usage. To get raw 30-minute interval data, contact JEA Economic Development (Jared Smith, jsmith@jaxenergy.com, 731-422-7325) and negotiate a custom export — options include quarterly CSV/Excel delivery or secure VPN/SFTP transfer.
Does JEA support Green Button or a public API?▾
No. JEA does not participate in the Green Button initiative (neither Download My Data nor Connect My Data) and publishes no developer API. Nectar provides API access to JEA billing and interval data — see docs.nectarclimate.com — alongside the customer portal, the UtilityNexus mobile app, and direct arrangements with the utility.
Can a third-party consultant be authorized to pull JEA billing data automatically?▾
There is no Share My Data portal or consent workflow. The supported path is a manual data-sharing arrangement: the customer signs a written authorization, the third party contacts JEA at (731) 422-7500, and both parties negotiate delivery format, frequency, and a data sharing agreement with the JEA Billing Department.
Does JEA support EDI for commercial billing?▾
EDI is not publicly documented. JEA's CSA Enterprise Billing System typically supports EDI, but no transaction sets (814, 820, 867, 810) or trading partner enrollment are exposed. Businesses needing EDI should contact JEA customer service at (731) 422-7500 and reference 'Electronic Data Interchange for business billing' to confirm capability.
How is demand billed for JEA commercial accounts?▾
Peak demand is calculated from the highest 30-minute interval in the billing period. That makes the handful of intervals that set the monthly peak the primary cost lever — staggering equipment starts, shifting discretionary load, and reviewing time-of-day rate eligibility with JEA all reduce demand charges.
What does Nectar's roadmap support level mean for JEA?▾
JEA is on Nectar's roadmap: automated ingestion is planned but not yet productized. Today, Nectar can work with JEA data via customer-downloaded PDF statements, negotiated CSV/SFTP exports through JEA's Economic Development team, or manual portal extraction while a native integration path is evaluated.
