Demand Response - Utility Commanded Load Control
Abstract:

Many Energy Service Providers and Market Operators administer customer side Demand Response and Load Control programs to ensure grid stability and stable operation during times of peak demand or system emergencies arising from generator outages or transmission and/or distribution constraints. With some programs, the customer – either residential or commercial - reduces the required load upon instruction from the Energy Service Provider or Market Operator. With other programs, the Energy Service Provider, Market Operator, or a Curtailment Service Provider remotely reduces the load. Some of these programs are conducted on a voluntary basis, where the customer can opt to maintain the level or load, or mandatory, where the customer either will be dropped off the system or will incur significant financial penalties for noncompliance. The customer may or may not realize benefits from the program, such as discounted rates. Some programs may be mandated to enable the Energy Service Provider to provide electric service to the customer in areas where there are transmission or distribution constraints. This function focuses on Demand Response/Consumer Load Control that is non responsive to price – pricing signals are not sent to the customer. Communication systems play a key role in this function as in the consumer control load configuration, instructions must be sent to the customer to reduce or eliminate load and verification of compliance/noncompliance must be obtained by the Energy Service Provider or Market Operator. In the configuration where the Energy Service Provider, Market Operator or CSP controls the load, commands must be sent to equipment at the customer site that will cycle down or cease operation. Verification of successful action must also be obtained.
