Agricultural & Pumping Interruptible (AP-I) Program
With SCE’s Agricultural and Pumping Interruptible Program (AP-I), you can receive a year-round monthly credit when you elect to allow SCE to temporarily interrupt electric service to your total load served. AP-I is offered on a contractual basis.
How The Program Works
Upon notification to SCE from the California Independent System Operator (CAISO) of the need to implement load reductions in SCE’s service territory, SCE will transmit a signal to the load control device installed on the customer’s pumping equipment, which will automatically turn off the customer’s total load served for the entire duration of the interruption or test event. Manual reset of the main circuit breaker/pump controller is required after an interruption or test event.
What You'll Receive
The AP-I program provides two types of credits based on the customer’s rate schedule:
- For customers on Rate Schedule PA-1 or PA-2, the AP-I program provides a per kWh credit applied against the customer’s bill.
- For customers on TOU rate schedules (for example, TOU-PA-B), the total credited amount will vary according to their average demand (kW) during time-of-use (TOU) periods.
AP-I TOU Credit
The AP-I Summer Average On-Peak, Summer Average Mid-Peak and Winter Average Mid-Peak credits shall apply to applicable TOU rate schedules. Note: TOU-PA-SOP customers will receive AP-I credits based on Time-of-Use time periods.
Who Can Participate
AP-I is available to agricultural and pumping customers with a measured demand of 37 kW or greater, or with at least 50 horsepower of connected load. As an AP-I participant, you must already be served under an eligible Agricultural and Pumping Rate Schedule, which includes Rate Schedule TOU-PA-ICE. AP-I is not available to customers receiving service on Option A of the TOU-PA tariff, customers receiving the Off-Peak credit provided under Schedule PA-1, or to customers served under experimental rate schedules.
What Is Needed
For billing purposes, AP-I customers are required to have interval meters installed at their locations, capable of recording usage in 15-minute intervals. AP-I customer load is controlled through SCE’s remote-controlled switch during interruption events only.
Event Notification
AP-I participants may request optional courtesy notifications of interruption events, via automated voice phone messaging, text to cell phone, e-mail, fax and/or pager. However, SCE does not guarantee customer receipt of the notification. SCE is not liable for service provider costs associated with event notifications to customer communication devices.
Note: Use of any of the above additional courtesy services IS NOT a substitute for installing SCE’s AP-I Control Device.
