Greeneville Energy Authority (Greeneville Light & Power) Rate Selection Guide
Greeneville Energy Authority (GEA, formerly Greeneville Light & Power System) is a Tennessee municipal electric utility serving roughly 41,000 meters across Greene County. C&I customers manage bills and usage through the NISC SmartHub portal at glps.smarthub.coop, but GEA documents no API, EDI, or formal third-party program — Green Button availability through the NISC platform is plausible but unconfirmed, so verify directly with the utility.
Market Overview
Municipal electric authority in Tennessee's regulated market; bundled monopoly service with local board governance and Tennessee Comptroller audit oversight. No retail choice.

Current Rate Schedules
Greeneville Energy Authority (GEA) is a TVA local power company serving ~40,875 meters across 600 square miles in Greene County, Tennessee. Business rates follow TVA's GSA structure: GSA1 (0-50 kW, energy-only), GSA2 (>50-1,000 kW, demand-billed), and GSA3-and-above industrial rates handled by contract. Every bill stacks an access charge, an energy charge, TVA's monthly Fuel Cost Adjustment (FCA), and — for residential/small commercial — a Demand Cost Recovery Adjustment (DCRA) capped at $0.005/kWh. GEA publishes 24 months of rate history on mygea.net; figures below are from the May 2026 statement cycle.
Effective: May 1, 2026 · Full Tariff Book →
| Schedule | Type | Applicability | Structure | Rate |
|---|---|---|---|---|
| GSA1 — Small Commercial (0-50 kW) | commercial | Commercial accounts with demand up to 50 kW (Rate 40) | Access charge $28.28/month + energy charge $0.09011/kWh + FCA ($0.03010/kWh in May 2026, varies monthly) + DCRA (load-factor-based, capped at $0.005/kWh). | ~$0.125/kWh all-in (May 2026) |
| GSA2 — Medium Commercial (>50 to 1,000 kW) | commercial | Commercial and light industrial accounts with demand between 50 and 1,000 kW | Access charge $50.00/month; energy: $0.10171/kWh first 15,000 kWh, $0.05494/kWh above; FCA ~$0.030/kWh (monthly); demand charge $13.81/kW (seasonal — $14.87/kW in summer months). | $0.055-$0.102/kWh + FCA+ $13.81/kW ($14.87/kW summer) |
| GSA3 and Above / MSB-MSD — Industrial Rates | industrial | Industrial accounts above 1,000 kW and manufacturing service classes (MSB/MSC/MSD) | Contract-based pricing — contact GEA at 423-636-6200. Industrial FCA published monthly (GSA3/GSA4 ~$0.0296/kWh, MSB/MSC/MSD ~$0.0247/kWh in May 2026); TVA manufacturing service rates reward high load factor. | — |
Rate Recommendations by Use Case
Storefront, office, or small shop in Greeneville
Small commercial accounts under 50 kW on GSA1.
Energy-only billing avoids demand charges, but GSA1 accounts pay the DCRA, which GEA sets from a load-factor calculation — steadier usage earns a lower (or credit) DCRA.
- Use GEA's 24-month rate table and bill calculator on mygea.net to forecast bills against your usage
- Keep load steady where possible — DCRA is load-factor-based and capped at $0.005/kWh
- Watch demand creep: crossing 50 kW moves you onto GSA2's $13.81/kW demand charge
Grocery, hotel, or light manufacturer between 50 kW and 1 MW
Demand-billed GSA2 accounts where the kW peak drives the bill.
GSA2's tail-block energy ($0.05494/kWh over 15,000 kWh) is nearly half the first-block rate, and the $13.81-$14.87/kW demand charge rewards flat operation — high-load-factor accounts bill out dramatically cheaper per kWh.
- Stagger HVAC and refrigeration starts after outages to avoid restoration peaks
- Note the summer demand premium (~$1/kW higher June-September) when scheduling production
- Pull SmartHub interval data monthly to find and fix the intervals that set your peak
Industrial plant above 1 MW
Large industrial accounts negotiating GSA3+ or TVA manufacturing service rates.
Pricing is contract-based with GEA and TVA; manufacturing service classes carry a lower FCA (~$0.0247 vs $0.0296/kWh) and reward high load factor and firm contract demand commitments.
- Engage GEA's commercial team (423-636-6200) before expansions — contract demand sizing affects every monthly bill
- Evaluate TVA manufacturing service eligibility if load factor exceeds ~60%
- Ask about TVA economic development incentives for new or expanding loads
Cost Optimization Strategies
GEA passes through TVA wholesale structures, so savings levers are operational: demand control on GSA2, load-factor management against the DCRA and block rates, correct class placement, and TVA EnergyRight incentives. GEA's unusually transparent 24-month published rate history makes bill modeling straightforward.
Demand peak management on GSA2
For: GSA2 accounts (>50 kW)
Every kW of monthly peak costs $13.81 ($14.87 in summer billing months). Sequence equipment starts, interlock large loads, and set SmartHub-based alerts before new peaks are set.
Load factor improvement (DCRA and block rates)
For: GSA1 and GSA2 accounts
Small commercial DCRA is computed from load factor and can swing between charge and credit (capped at $0.005/kWh); GSA2's over-15,000 kWh block at $0.05494 rewards spreading usage. Flat operation lowers both.
FCA-aware budgeting
For: All accounts; most material for energy-intensive operations
TVA's Fuel Cost Adjustment varied from ~$0.020 to ~$0.041/kWh over the last two years — a 2x swing. Use GEA's published FCA history to weather-normalize budgets and time discretionary energy-intensive work.
Industrial rate negotiation
For: Industrial accounts above 1,000 kW
GSA3+ and manufacturing service (MSB/MSC/MSD) accounts are contract-priced with a lower FCA. Right-size contract demand annually and review manufacturing service eligibility as load factor changes.
TVA EnergyRight incentives
For: All commercial and industrial customers
TVA's EnergyRight business program delivers assessments and rebates for lighting, HVAC, refrigeration, and custom measures through local power companies like GEA.

Frequently Asked Questions
How do commercial customers access GEA billing and usage data?▾
Register at glps.smarthub.coop with your account number and service address. SmartHub provides bill history (typically 2-3 years on NISC instances), payment records, and daily/weekly/monthly consumption with period comparisons. Check the My Usage tab for a Green Button Download button — if present, you can export interval XML.
Does GEA support Green Button data export?▾
Unconfirmed. The NISC SmartHub platform GEA runs on received DOE grants for Green Button development and other NISC utilities expose Download My Data, but GEA's instance is not GBA-certified and availability is not documented. Look for the button in My Usage or call (423) 636-6200 and ask specifically about Green Button and interval granularity.
Can a consultant or aggregator access GEA data on a customer's behalf?▾
Only manually. There is no Share My Data portal, API, or aggregator partnership. The customer signs a written authorization; the third party submits it with the account number to (423) 636-6200 or info@mygea.net, and GEA returns PDF statements in 2-5 business days. Avoid credential sharing — have customers export and share files instead.
Does GEA offer EDI for billing data exchange?▾
No documented EDI program exists — no implementation guides, trading partner enrollment, or transaction specifications. High-volume billing exchange requests should go to info@mygea.net with "EDI" in the subject line; the IT Director (Garrett Hensley) handles system access inquiries.
What does Nectar's roadmap support level mean for GEA accounts?▾
GEA is on Nectar's roadmap: automated ingestion is planned but not yet productized. Today, Nectar works with GEA data via customer-downloaded SmartHub exports (including Green Button XML if enabled) or authorization-based manual requests while native support is built.
