Interstate Power and Light (Alliant Energy) Data Access FAQ
Can a C&I energy consultant pull our IPL interval data programmatically?▾
No. IPL offers no Green Button or API. The practical options are to add the consultant as a view-only guest user in business My Account, or to export hourly/daily usage to Excel and share it. A Privacy Center request with written authorization is available for bulk historical data.
How much interval history can we get and at what granularity?▾
My Account exposes up to 13 months of history at hourly, daily, and monthly granularity for AMI smart-meter accounts. Data updates roughly daily; there is no real-time or sub-hourly feed.
Which rate schedule applies to a large commercial or industrial facility?▾
Facilities expecting more than 20,000 kWh per month for 12 consecutive months qualify for Large General Service (rate codes 447/487), which is a demand-plus-energy time-of-use tariff. Smaller commercial loads take Non-Residential General Service (rate codes 600/607).
Are IPL base rates expected to change soon?▾
A 2024 IUC rate case settlement established a conditional base-rate moratorium through October 2029, so base rates should be stable, but riders such as the Energy Adjustment Clause and Regional Transmission Service Clause continue to adjust periodically.
Does IPL support EDI for usage data?▾
No. IPL uses Transcepta only for supplier and vendor invoicing. There is no customer-facing EDI 867 historical usage exchange in this regulated Iowa territory.
