The project on Cost-Effective Demand Response (CEDR) sought to introduce a novel demand response (DR) lighting control technology that can be easily retrofit to existing buildings. The project team hoped to 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. CEDR takes a low-tech approach, doing only one simple task inexpensively-reducing loads during DR conditions.

Project team: CLTC and NEV Electronics

NEV Electronics produced a prototype system for testing. Based on feedback from the Underwriters Laboratories, the CEDR system had to be further modified at the component level. NEV Electronics plans to continue development and testing of the system with private funding.

The CLTC identifed and tested other off-the-shelf DR components to demonstrate demand response capabilities. The final report on this project is complete.
