Critical Peak Pricing- No event day

For those businesses on Time of Use Plus (CPP-D) it matters when you use energy. Time of Use Plus (CPP-D) is a commodity tariff that provides customers with an opportunity to manage their electric costs by either reducing load during high cost pricing periods or shifting load from high cost pricing periods to lower cost pricing periods. Critical Peak Pricing Event days are from 2 p.m. to 6 p.m. A maximum of 18 of these Critical Peak Pricing Event Days can be called annually.

Understanding Capacity Reservation

The Capacity Reservation Charge option allows customers to self-select an amount of electric usage (in kilowatts) that they want to protect from the high price of electricity during a CPP event, and pay for through a fixed monthly Capacity Reservation Charge (CRC). All usage during a CPP Event that is protected under the customer’s capacity reservation will be billed the corresponding energy charges for the time period but not the CPP Event Day Adder. All usage during a CPP Event that is not protected under the customer’s capacity reservation will be billed at the CPP Event Day Adder and the corresponding energy charges for the time period. Customers electing to reserve capacity for multiple meters are required to submit a separate capacity reservation level for each meter.

  • Frequently Asked Questions

    How many events can be called and when?

    CPP events may be called up to 18 times per calendar year. They can occur year-round, seven days a week from 2 p.m. to 6 p.m.

    What triggers a CPP event?

    We may call a CPP event when reductions in electricity use by customers are needed during periods of high electric demand or when electric system reliability is in jeopardy.  The trigger is based upon a forecasted system load.

    Other triggers can include electrical emergency alerts issued by the California Independent System Operator (CAISO) or an SDG&E system emergency that affects local grid operations.

    Am I required to shut off power during a CPP event?

    No. Customers are not required to reduce electric load during a CPP event. However, if your electric usage is not covered through a capacity reservation, all electric usage during a CPP event will be charged at a rate that is significantly higher than the normal Time-Of-Use rates. We can help you plan your demand reduction strategies ahead of time, so you can respond without major disruption to your operations when an event is called.

    Can a CPP event be cancelled after it is called?

    An event called as the result of an electrical system emergency alert issued by the CAISO can only be cancelled by the CAISO. For every two CPP events cancelled by the CAISO, one CPP event will be credited towards the maximum number of events that can be called during the year. CPP events activated based on criteria other than electrical system emergency alerts issued by the CAISO cannot be cancelled.

    SDG&E relies on forecasts so that we can give customers time to prepare for critical use periods. Because many businesses invest time and money into being able to respond to load reduction requests, we understand that it would complicate the situation to cancel a CPP event and have the business community keep re-adjusting their operations.

    Can I find out what SDG&E’s daily system peak was or find out what the peak demand forecast is for the next day?
    SDG&E’s system load information is available on the OASIS page on the CAISO website*, where you can view hourly system load and forecasts for each utility’s system within the CAISO control area.
