Load Profiles

We perform all load profiling. Sample data and customer specific interval metering, when available, will be used in the development of the total load profile for which the Energy Service Provider is responsible for providing generation and possibly transmission services.

The files below contain the generic class load profiles for I&M. Profiles are provided for the Irrigation Service (CCMIIRSA), General Service with Unmetered Service (CCMIFLAA), Large General Service (CCMILGSA), Large Power (CCMILPSA), General Service (CCMIMGSA), Municipal and School Service (CCMIMSSA), Security Outdoor Lighting (CCMIOSLA), Residential Electric Service (CCMIRESA), Streetlight Service (CCMISLSA), and Water and Sewage Service (CCMIWSSA) classes. These profiles may differ slightly from the profiles previously posted for the same overlapping time periods as we have had updates to previous data.

Each row contains data for one day, including date, class, and the 24 hourly average per customer in kW usage values. All information is expressed in hour-ending eastern standard time.

Metering and Usage History

Pre-Enrollment Customer List

Pre-Enrollment Customer List is not available at this time. For questions, please contact michiganchoiceoperations@aep.com

Historical Usage

Customer historical usage data is available to approved AES through the Business Partner Portal (BPP).

Net Metering Service

Standard Service Offer (SSO) and Open Access Distribution (OAD) are both included in the Net Metering Services.

Meter Reading Schedule

Annual Meter Schedule follows 21 reading cycles, which occur at different times of the month. These cycles correspond to the approximately 21 working days each month.

To find your billing cycle, look in the upper portion of your electric bill just below the account number (ex. CY 21).

Next, locate your reading cycle on the left side of the meter schedule and follow across to find the scheduled reading dates for the remainder of the year. The next scheduled read date is printed on each month’s electric bill and may be read one (1) business day before or one to two (1-2) business days after the date listed.

Loss Factor Information

  • An AES must include delivery losses as part of the load that is scheduled.
  • Metered Load multiplied by the Loss Factor equals the amount an AES should schedule for a given meter.
  • Primary and Secondary voltage values already include the transmission losses in the Loss Factor calculation.
  • To calculate to an individual Service Delivery Identifier (SDI), determine the tariff code, find it on the previous worksheet, and apply the value that relates to the service delivery voltage for that tariff code, also shown on the previous worksheet.
