Project Name: Automated Demand Response System
Facility: Cemex Quarry and River Plant

Scope: Upgraded existing PLC to accept ADR load-shed requirements, add ADR hardware and software, apply ADR system to both plants.

System: California Edison will send a signal to the customer to request a power reduction or load decrease during periods of high power demand. The existing systems received a PLC upgrade to accommodate the automated demand response (ADR) system. The previous systems could only operate at full load or be powered down, which required an upgrade before adding and commissioning an ADR system. When CEMEX has a load-shed request from Southern California Edison, the new ADR system will prioritize which machines can be powered down or placed in an idle state to save energy for the scheduled amount of time.

Benefit: The customer is able to save money by shedding energy-consuming loads and receiving energy incentives from Southern California Edison, by installing the system and participating in the program. This can result in thousands of dollars in savings, including energy incentives.
