ADR for Retail
Take control of your energy use—cut costs, save time, earn incentives
Between 2012 and 2017, 28 retail customers participated in the ADR Program, automating a total of 13 MW of load shed and qualifying for about $1.8 million in incentives.
Project Profiles
National Restaurant Chain Enhances Store Intelligence
Measures: Optimize and manage HVAC system
Program Incentive: $26,250
Load Shed: 75 kW
Description: The customer installed new HVAC system controls on each rooftop HVAC unit. Each unit’s controller wirelessly communicated with a central controller, which coordinated the timing of and optimized the rooftop HVAC unit operations. The controls automated DR program participation, mitigated monthly peak demand charges, and improved efficiency. The customer maintained occupant comfort during DR events by programming the system to limit HVAC demand to no less than 50 percent of the required cooling load.
National Department Store Saves BIG
Measures: Optimize and manage HVAC system
Program Incentive: $667,000
Load Shed: 1,936 kW
Description: This Fortune 500 department store with 36 stores and more than three million square feet in PG&E’s service area has long recognized that savvy energy management strategies benefit their bottom line, customers’ shopping experience, and the environment. Since installation of advanced controllers that reduced the duty cycle of their HVAC units by 10-20 percent, the national chain has accumulated annual savings of $150,000 per year from increased energy efficiency, decreased peak demand charges, and automated participation in PG&E’s demand response program.
National Hardware Store Chain Takes Care of Its Bottom Line
Measures: Optimize and manage HVAC and lighting systems
Program Incentive: $597,000
Load Shed: 3,734 kW
Description: The customer implemented lighting and HVAC control strategies at 63 of its stores (approximately 7.5 million sq. ft.) across the PG&E service area. Leveraging the customer’s Enterprise, central energy control system, the retailer developed a control strategy that dimmed lights in a checker pattern and increased space temperature throughout the store by two degrees Fahrenheit. This participation strategy did not significantly impact employee and customer comfort. Leveraging the customer’s multi-site, central energy control system enabled their entire portfolio to participate in DR without increased labor resources.
Common strategies for temporarily reducing load for demand response:
HVAC:
- Temperature reset
- Cycle rooftop units
- Lock out compressor stage (if available)
- Cycle fans
- Pre-cooling
- Shut off chiller
- Reset chiller chilled water temperature
Lighting:
- Dim lights by 10%, 15%, 20% or more
- Dim or turn off lights in alternate fixtures or rows
- Dim or turn off lights in low traffic areas
Other:
- Turn off one or more banks of elevators
- Turn off one or more banks of escalators
