What is the Agricultural and Pumping Interruptible Program (AP-I)?
Southern California Edison’s (SCE) AP-I program is available to agricultural and pumping customers currently served under an eligible Agricultural and Pumping Rate Schedule. With AP-I you can receive monthly bill credits for allowing us to temporarily interrupt electric service to your pumping equipment during periods of peak energy demand. Bill credits are applied year round, even when no interruptions occur.
How It Works
A control device is installed near your meter or pumping equipment to control the total load served. When the grid is experiencing high demand, the California Independent System Operator (CAISO) notifies us that energy use must be reduced. We then transmit a signal to the device that automatically turns off electricity until critical demand—or the occasional test—has ended.
Ready to Apply?
You may enroll in AP-I at any time. To enroll, you will need to:
Designate the service account for participation
Submit the AP-I Contract for Interruptible Service for approval
Provide a suitable location for the installation of SCE’s load-control equipment, where it is accessible to us during business hours and/or reasonable hours, for maintenance and repairs; and
Comply with all provisions within 30 days of contract execution.
To participate, business must have a measured demand of 37kW, or at least 50 horsepower of connected load. Businesses with service under Option A of the TOU-PA tariff or receiving off-peak credits through Schedule PA-1 are not eligible.
An interruption can occur at any time — seven days a week, 365 days a year. Interruption events are limited to:
One event per day (six hours)
10 events per month
180 hours per calendar year
What are the requirements for AP-I?
For billing and participation purposes, your location is required to have interval meters capable of recording electricity use in 15-minute intervals. There is a six-month minimum enrollment requirement if enrolled by April 30 in a given year and a twelvemonth minimum enrollment requirement if enrolled after April 30 in a given year. Changes or cancellations are only available during the annual adjustment windows outlined in the tariff. To view the AP-I Tariff, go to sce.com/tariffbooks.
