Market Overview
4-County is a member-owned electric cooperative and TVA power distributor. It buys wholesale power from TVA and resells it at board-approved retail rates following TVA distributor rate schedules. There is no retail electric choice for any customer class. As a cooperative, governance is by a member-elected board rather than direct state rate regulation of data access.

Rate Recommendations by Use Case
Commercial facility at or below 5,000 kW
Office, retail, institutional, or light-industrial sites on General Power GSA.
GSA is the default C&I schedule; the demand charge (highest 30-minute demand) is the main controllable cost.
- Monitor daily usage in the My 4-County portal
- Stagger large equipment startups to limit coincident demand
- Evaluate TGSA if load can shift off-peak
Large manufacturer (5,000-15,000 kW)
Manufacturing plant (SIC 20-39) eligible for Manufacturing Service MSB.
MSB is purpose-built for manufacturing load profiles; confirming correct schedule placement and managing demand drives savings.
- Verify MSB vs GSB placement with 4-County business billing
- Manage the highest 30-minute demand
- Request interval data timeline for better load-factor analysis
Load-flexible C&I site
Customers (on/off-peak demand 5,000 kW or less) able to shift discretionary load to off-peak periods.
TGSA rewards off-peak consumption, lowering on-peak demand and energy charges for flexible operations.
- Identify shiftable loads (pumping, charging, batch processes)
- Compare TGSA vs GSA economics with 4-County
- Schedule operations around on-peak windows
Data-driven energy manager
C&I customers needing granular data for benchmarking or M&V while interval access is unavailable.
Limited data access means relying on portal daily usage and manual authorization; plan for a future Green Button CMD launch.
- Export daily usage regularly from the portal
- Use a signed authorization letter for consultant access
- Ask 4-County about the interval-data/Green Button timeline

Cost Optimization Strategies
With TVA-structured demand charges and a time-of-day option, 4-County C&I customers benefit most from demand-peak management and, where feasible, shifting load to off-peak under TGSA. Limited data access means manual portal monitoring is the main analytical tool until interval downloads arrive.
Demand peak management
For: GSA, GSB, MSB
Demand is billed on the highest 30-minute metered demand; staggering equipment and limiting coincident peaks reduces the demand charge component.
Time-of-Day (TGSA) load shifting
For: TGSA-eligible C&I
Eligible customers (on/off-peak demand 5,000 kW or less) can move discretionary load to off-peak periods to lower on-peak demand and energy charges.
Manufacturing Service (MSB) qualification
For: Manufacturers 5,000-15,000 kW
Manufacturers (SIC 20-39) at 5,000-15,000 kW should confirm placement on MSB, which is tailored to manufacturing load profiles.
Portal usage monitoring
For: All C&I accounts
Until interval downloads exist, monitor daily usage in the My 4-County portal to track demand trends and validate billing.
To implement these strategies, you need your 15-minute interval data. Learn how to download 4-County Electric Power Association interval data →
Frequently Asked Questions
Can my energy consultant get my 4-County interval data?▾
Not via an automated channel. 4-County has no Green Button, API, or aggregator program. The current path is manual: the customer views/exports billing and daily usage from the My 4-County portal and shares it under a signed authorization letter.
Is 15-minute interval data available for C&I accounts?▾
Not yet to customers. 4-County is deploying Itron Gen5 AMI; only daily usage is exposed in the portal today. Interval downloads may follow once deployment completes.
Does 4-County support EDI (810/820/867) for business billing?▾
No EDI program is documented. Business customers should call 1-800-431-1544 for the business billing department and use ACH/bank draft or the online portal as alternatives.
Where can I see C&I rate schedules?▾
4-County's commercial rates (General Power GSA/GSB, Manufacturing Service MSB, Time-of-Day TGSA) are published at 4county.org/business/commercial-billing-rates/. They follow the TVA distributor structure with charges adjusted by the current TVA Adjustment Addendum.
Can C&I customers choose a different supplier?▾
No. 4-County is a member-owned TVA distributor in a regulated market with no retail choice; power is bought wholesale from TVA and sold at board-approved rates.
