Cost-Effective Demand Response (CEDR)
Utilities need additional demand response (DR) capacity to avoid rolling blackouts during peak usage periods and meet regulatory requirements. Most existing, commercial lighting does not currently contribute to peak demand reductions. Existing retrofit lighting control solutions are too expensive for DR use, which leaves existing, interior, commercial lighting as a largely untapped DR resource.
Cost-Effective Demand Response (CEDR) research by Lighting California's Future seeks to introduce a novel demand response (DR) lighting control technology that can be easily retrofit to existing buildings.
CEDR makes retrofit installation economical by using existing power wiring to transmit a load shed signal to designated lighting loads. This signal, introduced at the lighting panel and transmitted to receivers installed in existing bi-level light switches, tells receivers to turn off half the lights.
This research project will develop a new system capable of receiving a utility demand reduction signal and transmitting, over the building power lines, a load-shed signal to multiple receiver devices. The outcome of the project is the development and commercialization of a novel demand responsive lighting technology.
CEDR takes a low-tech approach, doing only one simple task inexpensively - reducing loads during DR conditions.
Applications
■ Buildings with lighting controlled by bi-level switching.
■ Buildings with significant sheddable plug loads.
■ ESCOs with the above customers.
■ Utilities requiring more automatic DR capacity.
Key project members are the CLTC, NEV Electronics, and SCE. Collaborators include NEV Electronics, Benya Lighting, California Lighting Technology Center (CLTC), Southern California Edison, and Architectural Energy Corporation.
