Rate Schedules & Tariff Analysis
MidAmerican C&I rates are regulated and bundled (except Illinois delivery choice). Iowa rates have been notably stable for decades thanks to settlement agreements and wind-driven wholesale revenue. The key C&I cost levers are demand charges on large general service and seasonal energy pricing, since customers cannot shop generation supply in Iowa.
MidAmerican Energy Rate Schedule List
| Schedule | Applicability |
|---|---|
| General Service | Small to mid-size commercial |
| Large General Service | Demand-metered C&I |
| General Energy Time-of-Use | Commercial TOU |
| Gas General/Transportation | Commercial & industrial gas |
MidAmerican Energy Rate Features & TOU Details
- Regulated bundled service (no IA supplier choice)
- Demand ($/kW) charges on large general service

MidAmerican Energy Data Access FAQ
How does an Iowa business get interval (15-minute) usage data from MidAmerican?▾
Log in to My Account and open Usage/Usage History to view and export recent 15-minute interval data to CSV/Excel where AMI supports it. For older history, contact the Business Advantage team at 800-329-6261. Illinois suppliers use a dedicated interval data request form (about $5 per meter). MidAmerican does not offer Green Button or an automated interval API.
Can a consultant or aggregator pull our data automatically?▾
Not via API. MidAmerican has no public API and does not support Green Button Connect My Data. A third party must submit a signed Billing/Usage History Authorization (BillingHistoricalRequests@MidAmerican.com) or a General Customer Authorization, after which data is delivered manually (typically CSV/Excel within 5-10 business days). For ongoing enterprise billing, EDI 810/820 can be implemented.
What electric rate classes apply to C&I customers in Iowa?▾
Iowa C&I customers take regulated bundled service under MidAmerican's general service and large general service schedules. Smaller accounts pay a customer charge plus per-kWh energy charges; larger accounts are demand-metered with per-kW demand charges and energy charges, with seasonal (summer/winter) differentials. Exact charges are published in MidAmerican's Iowa electric tariff filed with the Iowa Utilities Commission.
Are MidAmerican's Iowa electric rates stable?▾
Historically, yes. MidAmerican's Iowa electric base rates have been unusually stable for decades under successive settlement agreements with the Iowa Office of Consumer Advocate; the company offsets cost increases with wholesale market revenue. A $135.6 million increase was approved in 2014 and phased over three years. Natural gas rates are adjusted more regularly, including a 2026 gas rate case. Always confirm current charges in the tariff.
How do gas transportation customers access usage data?▾
Through the GasMAIN portal (gasmain.midamericanenergy.com), where transportation customers can submit nominations and view daily and hourly gas usage history without manual requests. Support is available at 800-444-3123 or gascoordinator@midamerican.com.
