Dickson Electric System (City of Dickson, TN) Rate Selection Guide
Dickson Electric System (DES) is the City of Dickson's municipal electric utility, serving nearly 39,000 customers across five Tennessee counties with TVA-supplied power. DES runs a fully deployed Sensus FlexNet AMI network with 15-minute interval metering, but customer-facing access is portal-based only — no Green Button, API, EDI, or aggregator programs exist, so third parties work through manual written authorization.
Market Overview
Dickson Electric System is a municipal distribution utility purchasing wholesale power from the Tennessee Valley Authority (TVA). Tennessee has no retail electric choice; customers take bundled service from DES under TVA-influenced rate schedules published monthly.

Current Rate Schedules
Dickson Electric System (DES) is a municipal TVA local power company; retail rates follow TVA's wholesale rate structure and change monthly with TVA's Fuel Cost Adjustment. DES publishes its full rate sheets as monthly PDFs on the Power Rates page. Commercial, industrial, government, and institutional customers take service under the General Power Rate Schedule (GSA), tiered by demand: GSA-1 (<50 kW), GSA-2 (50-1,000 kW), and GSA-3 (1,000-5,000 kW). Demand is billed on the highest 15-minute interval each month. Qualifying manufacturers on GSA-3 can earn TVA's General Manufacturing Credit. See the monthly rate PDFs for current dollar figures.

|---|---|---|---|---|
| GSA-1 General Power | commercial | Small businesses and non-residential buildings (barns, workshops, garages) with demand under 50 kW and monthly energy under 15,000 kWh. | Customer charge plus a flat energy charge per kWh; no demand charge. Rates updated monthly with TVA fuel cost adjustment — see current month's rate PDF for figures. | — |
| GSA-2 General Power | commercial | Commercial and institutional customers with demand between 50 kW and 1,000 kW, or under 50 kW with energy exceeding 15,000 kWh/month. | Customer charge, per-kW demand charge on demand above 50 kW (first 50 kW free of demand charge), and tiered energy charges. Demand billed on the highest 15-minute interval of the month. See monthly rate PDF for current rates. | —+ Per-kW charge on billing demand above 50 kW; see monthly rate sheet for current figure |
| GSA-3 General Power | industrial | Large commercial and industrial customers with contract or 12-month peak billing demand between 1,000 kW and 5,000 kW. | Customer charge, per-kW demand charges (separate blocks at and above 1,000 kW), and a lower flat energy charge than GSA-1/GSA-2. Manufacturers with SIC codes 2000-3999 and a signed agreement qualify for the General Manufacturing Credit on metered demand over 1,000 kW.

Rate Recommendations by Use Case
Manufacturers between 1,000-5,000 kW
Manufacturing plants in DES territory should take GSA-3 service and execute a General Manufacturing Credit agreement.
TVA's GMC applies a credit to every kW of firm billing demand and every kWh of firm energy in months where metered demand exceeds 1,000 kW — a structural discount designed to retain Valley manufacturing load. SIC codes 2000-3999 generally qualify.
- Sign the GMC contract before the production season — the credit only applies in qualifying months
- Keep metered demand at or above 1,000 kW in production months to trigger the credit
- Download the GMC PDF from DES and verify the credit appears on each bill
Mid-size commercial — grocery, distribution, schools, healthcare (50-1,000 kW)
GSA-2 accounts pay demand charges only on kW above 50, making peak management the dominant cost lever.
Because the first 50 kW carries no demand charge and demand is set by a single 15-minute interval, flattening load directly shrinks the billed-demand block. DES evaluates rate classification on trailing 12-month demand and energy, so sustained reductions can even re-tier an account.
- Stagger HVAC and refrigeration starts after outages to avoid recovery spikes
- Request interval data from DES to find your monthly 15-minute peak
- Watch the 15,000 kWh energy-tier breakpoint when budgeting
Small business and auxiliary buildings (<50 kW)
Shops, offices, and outbuildings under 50 kW and 15,000 kWh fit GSA-1, where billing is purely energy-based.
With no demand component, GSA-1 bills track consumption one-for-one — efficiency upgrades pay back directly, and there is no penalty for peaky usage. Crossing 50 kW or 15,000 kWh moves the account to GSA-2's demand-billed structure.
- Monitor monthly kWh against the 15,000 kWh GSA-1 ceiling
- DES right-sizes rates on 12-month history — ask for a rate review after major equipment changes
- Check single-phase vs. three-phase customer charges on the monthly rate sheet
Cost Optimization Strategies
As a TVA local power company, DES passes through TVA's wholesale structure: monthly fuel cost adjustments, 15-minute demand billing on GSA-2/GSA-3, and TVA-funded incentive programs. Cost optimization centers on demand management, correct GSA tier placement, capturing the General Manufacturing Credit, and leveraging TVA EnergyRight programs.
15-minute peak demand management
For: GSA-2 and GSA-3 demand-billed accounts
GSA-2 and GSA-3 demand charges are set by the single highest 15-minute interval each month. Sequence motor starts, interlock large loads, pre-cool buildings, and use DES interval data to identify and clip peaks.
General Manufacturing Credit enrollment
For: Manufacturers on GSA-3 with demand at or above 1,000 kW
GSA-3 manufacturers (SIC 2000-3999) with a signed GMC agreement receive per-kW and per-kWh credits in every month metered demand exceeds 1,000 kW. Many eligible plants never execute the agreement and leave the credit unclaimed.
GSA tier verification
For: All commercial accounts near the 50 kW / 15,000 kWh or 1,000 kW boundaries
DES classifies accounts on trailing 12-month kW and kWh. After downsizing, equipment retirement, or efficiency projects, request reclassification — dropping from GSA-2 to GSA-1, or correctly tiering near the 1,000 kW boundary, changes the bill structure entirely.
TVA EnergyRight incentives
For: All commercial and industrial customers
As a TVA distributor, DES customers can access TVA EnergyRight business programs — prescriptive and custom incentives for lighting, HVAC, compressed air, and process efficiency that reduce both kWh and billed demand.
Fuel cost adjustment timing awareness
For: Energy-intensive operations with schedulable loads
DES rates change monthly with TVA's fuel cost rider — the reason DES publishes twelve rate PDFs per year. Track the monthly rate sheets when budgeting and consider scheduling flexible high-consumption activities in lower-FCA months.

Frequently Asked Questions
Does Dickson Electric System have 15-minute interval data for commercial accounts?▾
Yes at the meter level — DES's Sensus FlexNet AMI collects 15-minute intervals and uses them for demand charge calculations. But the portals only show daily/monthly graphs. For raw 15-minute or hourly data, call (615) 446-9051 with your account number, dates, and granularity; data is emailed (usually PDF) typically within 24 business hours.
Can an energy consultant pull DES data through an aggregator or API?▾
No. DES has no API, no Green Button, no EDI, and no aggregator partnerships. The only path is manual: the customer signs a written authorization naming your firm, the accounts, the data types, and the duration; you submit it to descustomerservice@dicksonelectric.com and request data per engagement, with a 2-5 business day turnaround.
What portals does DES offer for self-service data access?▾
Three: the primary UtilityNexus portal (https://dicksonelectric.utilitynexus.com/) for bills and usage graphs, a CentraVu portal (http://portal.dicksonelectric.com/) for consumption and cost analysis, and the MyUsage portal. The Dickson Electric System mobile app mirrors the UtilityNexus credentials with usage graphs and payment history.
Is Dickson Electric System on a deregulated market?▾
No. DES is a municipal utility in TVA territory; Tennessee has no retail choice. DES publishes its power rates monthly (https://www.dicksonelectric.com/faqs/power-rates-2025/), and wholesale costs flow through from TVA — there is no supplier shopping or choice-market EDI.
How can Nectar ingest DES data today?▾
DES is on Nectar's roadmap for automated support. Today the workable approach is customer-authorized bill collection: PDF statements from the UtilityNexus portal plus, where needed, customer-service requests for interval data under a standing written authorization. Because the AMI already records 15-minute intervals, data quality is good once the manual channel is established.
