Interval Data & Smart Meters

SLEMCO is deploying Honeywell Advanced Metering Infrastructure (AMI) across its territory; the rollout is ongoing as of 2025-2026. Smart meters support hourly and 15-minute interval collection. SmartHub currently provides daily/monthly usage analytics for all members; finer interval data becomes available as AMI completes. Third parties can request interval data via a customer-authorized request to the SLEMCO data access coordinator.

Meter Technology
Honeywell AMI smart meters (rollout ongoing 2025-2026); legacy meters still present in some areas.
Electric Granularity
Daily usage available now; hourly and 15-minute interval data becoming available as smart meters are deployed (via SmartHub or by request).
Gas Granularity
Not applicable (electric-only cooperative).

06

Rate Schedules & Tariff Analysis

SLEMCO's LPSC-approved tariff scales from energy-only small commercial service (Rate 11) to demand-metered large commercial and industrial schedules. Smaller accounts pay a fixed customer charge plus per-kWh energy; as accounts grow, a per-kW billing-demand charge is added, making peak demand the key cost driver for larger members. Because SLEMCO buys all power wholesale, the Power Cost Adjustment (PCA) and Base Energy Rate Adjustment (BEA) are significant, variable line items across all classes. Reported class averages are about 12.15 cents/kWh (commercial) and 9.43 cents/kWh (industrial); the lower industrial average reflects high load factor and demand-rate economics. Per-component dollar figures are not published online and should be confirmed in the LPSC tariff.

Southwest Louisiana Electric Membership Corporation (SLEMCO) Rate Schedule List

ScheduleApplicability
Small Commercial (Rate 11)Energy-only small commercial; no demand charge.
Large Commercial (Rate 12)Demand-metered; customer + energy + per-kW demand.
Industrial / Large PowerHigh load-factor industrial; three-part demand rate, ~9.43 c/kWh avg.

Southwest Louisiana Electric Membership Corporation (SLEMCO) Rate Features & TOU Details

Limitations & Considerations

  • No formally published third-party data access program; access requires a customer Letter of Authorization.
  • Green Button Download My Data is emerging but not formally advertised; Connect My Data (API) is not launched.
  • AMI rollout is incomplete, so 15-minute interval data is not available to all accounts yet.
  • No public developer API or developer portal.
  • Detailed C&I per-component rate figures are not published online; the LPSC tariff is the authoritative source.

Southwest Louisiana Electric Membership Corporation (SLEMCO) Data Access FAQ

How can a commercial or industrial member get interval (15-minute) data from SLEMCO?

Members with Honeywell AMI meters can view usage in SmartHub; finer interval data is expanding as the rollout completes. For historical 15-minute or hourly data, submit an authorized request to customer.service@slemco.com or call 337-896-5200; SLEMCO delivers via CSV/XML through its meter data management system, typically in 5-15 business days.

Does SLEMCO offer Green Button or an API for third-party energy managers?

Green Button Download My Data is emerging on SLEMCO's NISC SmartHub platform but is not formally advertised; Green Button Connect My Data (automated API) has not launched. There is no public developer API. The supported third-party path is a customer Letter of Authorization request, or contacting NISC about SmartHub partner access.

How are SLEMCO commercial and industrial rates structured?

SLEMCO rate schedules are filed with and approved by the Louisiana Public Service Commission. Commercial service uses Rate 10/11/12 classes; larger commercial and industrial accounts move to demand-metered schedules combining an energy charge, a per-kW demand charge, and a customer charge. A Power Cost Adjustment (PCA) and Base Energy Rate Adjustment (BEA) pass through wholesale power and fuel costs. Exact per-component figures are in the LPSC tariff; consult SLEMCO or the LPSC filing for current rates.

What does SLEMCO charge commercial and industrial members on average?

Based on the most recent reported data, SLEMCO's average commercial rate is about 12.15 cents/kWh and the average industrial rate is about 9.43 cents/kWh, with roughly 9,100 commercial and 25 industrial accounts. Actual billed rates depend on the assigned schedule, demand, and the monthly PCA/BEA adjustments.

Can a third party access data without the member's login credentials?

Yes. The recommended path is a signed Letter of Authorization or Power of Attorney submitted to SLEMCO Customer Service, after which SLEMCO delivers the data directly. When Green Button Download is available, a member can also download and share their own ESPI file. Credential sharing is discouraged.
