Current Rate Schedules
Commercial and industrial electric rates follow TVA-approved schedules administered by Huntsville Utilities, effective May 1, 2026. Rates include a customer (service) charge, an energy (kWh) charge, and—for larger accounts—a demand (kW) charge, plus a monthly TVA Fuel Cost Adjustment. The schedules below reflect the published rate structure; specific dollar figures are filed in the Huntsville Utilities rate documents and TVA schedules and were not asserted here because exact current per-unit amounts were not verifiable in a retrievable public source at time of research.

Rate Recommendations by Use Case
Mid-size commercial building (50–1,000 kW)
Office, retail, or light-industrial sites should focus on demand management under the GSA demand-tier structure.
Demand charges begin above 50 kW; flattening the load curve directly lowers billed kW.
- Export 15-minute interval data monthly
- Identify and stagger peak equipment cycles
- Monitor the monthly TVA Fuel Cost Adjustment
Large industrial / manufacturing (> 1,000 kW)
Large loads should pursue contract-level engagement with the C&I department and rigorous demand optimization.
Above 1,000 kW, demand and energy charges dominate; contract terms and load factor materially affect cost.
- Engage com_ind@hsvutil.org for contract terms
- Improve load factor to reduce peak penalties
- Use Green Button ESPI exports for third-party analytics
Multi-site portfolio / energy consultant
Aggregators and consultants should standardize on Green Button ESPI exports since the utility offers no official API.
Huntsville lacks a public utility API and EDI; Green Button file sharing and Nectar's API are the most reliable scalable channels.
- Collect Green Button ESPI files from each customer
- Use Nectar's API for programmatic billing and interval data access (docs.nectarclimate.com)
- Establish a C&I data-sharing agreement for bulk needs
Sustainability / ESG reporting
Facilities teams tracking Scope 2 emissions should pull interval data and combine with TVA grid emissions factors.
15-minute interval data enables granular consumption accounting for ESG disclosures.
- Download 14 months of interval data via Green Button
- Map kWh to TVA emissions factors
- Automate monthly exports for continuous reporting
Historical Rate Trends
Huntsville Utilities electric rates track TVA wholesale costs. The utility has implemented Board/Council-approved retail rate modifications and passes through TVA's monthly Fuel Cost Adjustment, which drives most short-term bill variability.

Cost Optimization Strategies
For C&I customers, the largest savings opportunities are demand-charge management and shifting usage to lower-cost periods given the seasonal TVA-based structure.
Peak demand management
For: GSA accounts above 50 kW
Stagger equipment startups and shed non-critical load during peak intervals to lower billed kW demand.
Interval data analytics
For: All AMI-metered C&I accounts
Export 15-minute interval data (Excel/Green Button) to identify load spikes, baseline drift, and equipment inefficiencies.
Fuel Cost Adjustment awareness
For: All electric C&I accounts
Track the monthly TVA Fuel Cost Adjustment and shift discretionary load to lower-FCA months where feasible.

Frequently Asked Questions
Does Huntsville Utilities offer an API for commercial energy data?▾
No official public API exists. C&I customers and consultants should use Green Button ESPI downloads or Excel exports from the My HU / SmartHub portal. For bulk or programmatic access, contact the C&I department at com_ind@hsvutil.org. A community-built NISC SmartHub tool exists but is unofficial.
What interval granularity is available for commercial accounts?▾
AMI smart meters provide 15-minute electric interval data, exportable to Excel or as Green Button ESPI XML, with up to 14 months of history available for download.
Can a third party access my business's usage data?▾
There is no formal Share My Data program. The recommended method is for the customer to download Green Button ESPI files and share them securely, or to establish a data-sharing arrangement directly with the C&I department.
How are commercial electric rates structured?▾
Rates follow TVA-approved General Service (GSA) schedules tiered by contract demand (≤50 kW, 50–1,000 kW, 1,000–5,000 kW, and >5,000 kW). Accounts above 50 kW incur demand (kW) charges, and all accounts see a monthly TVA Fuel Cost Adjustment.
Does Huntsville Utilities support EDI for commercial billing?▾
No. Per the DOE Energy Data Management Guide, only Alabama Power offers EDI in Alabama. Huntsville commercial customers should use Excel or Green Button exports instead.
