Base Interruptible Program
Base Interruptible Program details
The Base Interruptible Program (BIP) is intended to provide load reduction on PG&E's system on a Day-of basis when the California Independent System Operator (CAISO) issues a curtailment notice. Customers enrolled in the program will be required to reduce their load down to or below its Firm Service Level (FSL).
How It Works
Customers are given at least 30 minutes advance notice, and there is a maximum of one event per day and six hours per event. The program will not exceed 10 events per month, or 180 hours per year. The BIP may be called when CAISO has determined that a Stage 1 emergency is imminent, Stage 1, Stage 2 or Stage 3 emergency, during a transmission system contingency, or when needed based on forecasted system conditions. Once enrolled, customers may adjust their Firm Service Level (FSL) or discontinue participation once each year during the month of November. The FSL must be no more than eighty-five percent (85%) of each customer's highest monthly maximum demand during the summer on-peak and winter partial-peak periods over the past 12 months.
Customers have the option to add an Under-frequency Relay (UFR) device and earn additional incentives.
Customers may enroll directly with PG&E using either the Online Enrollment System or their sales representative, or customers can sign up with third-party BIP Aggregators.
Enroll Online
Applications for the Base Interruptible Program are accepted on a year-round basis. Please contact your PG&E account representative for further details.
Program Eligibility
To qualify for BIP you must meet the following requirements:
Required:
- Customers must take service on a demand time-of-use (TOU) rate schedule
- At least 100 KW or higher maximum demand during the summer on-peak and the winter on-peak for at least one month over the previous 12 months
Eligible:
- Bundled customers
- Direct Access (DA)
- Community Choice Aggregation (CCA)
Ineligible:
- Rate schedules AG-R and AG-V
Equipment Requirements
- Your facility must have an electric interval meter that can be read remotely by PG&E.
- If you are a bundled customer but do not have an electric interval meter that can be read remotely by PG&E, we will install one at no cost to you provided you meet the minimum program requirements and agree to remain in the program for at least one full year.
- If you are a direct access customer but do not have an electric interval meter that can be read remotely by PG&E, please contact your electric service provider. For additional details, see Electric Schedule E-BIP Base Interruptible Program (PDF, 354 KB).
Incentive Payments
Incentive payments will be paid on a monthly basis based on the directly enrolled customers or aggregated portfolios monthly potential load reduction (PLR) amount:
The PLR will be multiplied by the appropriate incentive level to determine the monthly incentive payment.
Potential Load Reduction | Monthly Incentive (November - April) | Monthly Incentive (May - October) | |
---|---|---|---|
500 kW and below |
$9.50 per kW |
$10.50 per kW |
|
501 kW to 1,000 kW |
$10 per kW |
$11 per kW |
|
1,001 kW and above |
$10.50 per kW |
$11.50 per kW |
Note: Current incentive rates are authorized by the CPUC through 2023.
EXCESS ENERGY CHARGE
Participants are penalized at $6.00/kWh for energy usage over their FSL during a curtailment.
Third-Party Aggregators
A customer may enroll directly with Pacific Gas and Electric Company using the Online Enrollment System or with a third-party Aggregator: An Aggregator is an entity appointed by a customer to act on behalf of the customer with respect to all aspects of the program, including receipt of notices, receipt of incentive payments and payment of penalties.
