Retail Demand Response Survey Headcounts 2022 Carl L Raish Principal Load Profiling and Modeling DSWG Meeting December 12, 2022
DR Survey Overview Annual surveys of REP and NOIE administered demand/price response programs 2013 2022. Demand response categories: 4-Coincident Peak (4CP) Advise-Control (4CP) - REP/NOIE advises Customers to curtail or directly controls Customer Load on expected 4-Coincident Peak (4CP) days. For NOIEs, a rate incentive also may be provided to the Customer to reduce load. 4-Coincident Peak (4CP) Incentive - (NOIEs only) Rate incentives provided to Customers to encourage or cause them to reduce Load during actual or potential 4CP intervals during summer months (June through September). Customer determines when to curtail Load without advice or control from a NOIE. Conservation Voltage Reduction (CVR) - (NOIEs only) The NOIE Transmission and/or Distribution Service Provider (TDSP) reduces voltage at selected substations to reduce Load when conservation is needed. Free Days and/or Time Periods (FDH) - (REPs only) Customer is not charged for consumption on specified days of week, holidays, and/or time periods of the day. For example: free nights and weekends. Alternatively, Customer is allowed to designate days during a billing period for which consumption is not charged. Indexed Day Ahead (IDA) - May or may not include fixed pricing for a defined volume of usage, but does include pricing for some or all usage, indexed to the Day-Ahead Settlement Point Prices for the premise Load Zone. Charges are based on Customer's actual interval data. 3 PUBLIC
DR Survey Overview Demand response categories (continued): Indexed Real-Time (IRT) - May or may not include fixed pricing for a defined volume of usage, but does include pricing for some or all usage, indexed to Real-Time Settlement Point Prices. Charges are based on Customer's actual interval data. Indexed Other (IOT) - May or may not include fixed pricing for a defined volume of usage, but does include pricing for some or all usage, indexed to something other than Day-Ahead or Real- Time prices. Other Direct Load Control (OLC) - Agreements that allow the REP/NOIE/third party to control the Customer s Load remotely for economic or grid reliability purposes. This category applies to Direct Load Control (DLC) not associated with other categories. Other Voluntary Demand Response (OTH) - Any retail program not covered in the other categories that includes a Demand response incentive or signal. General conservation messages to all or a majority of a REP s or a NOIE s Customers are not applicable. Peak Rebates (PR) - A retail offering in which the Customer is eligible for a financial incentive paid for Load reductions taken during periods of time identified by the Load Serving Entity (LSE) and communicated to the Customer during the prior day or the event day or both. LSE has defined a method to identify whether a Customer has responded and to quantify the response amount. Payment (rebate) to Customer is based upon the magnitude of the Customer s response. Time of Use (TOU) - Prices that vary across defined blocks of hours, with predefined prices and schedules. (As used here, does not apply to seasonal adjustments.) 4 PUBLIC
