Frequently Asked Questions
- How is this different than Demand Response?
Permanent Peak Load Shifting is a significantly different approach to energy conservation than Demand Response. In a Demand Response program, when the Utility is nearing a power shortage, they communicate to participating Customers that they need to eliminate demand. This is usually achieved by shutting off lights and equipment, increasing temperature setpoints, or other methods. The drawbacks of Demand Response are that these changes typically have a negative impact on your day-to-day business operations, and even when Demand Response is not called for you are still paying the premium cost for On-Peak energy.
Permanent Peak Load Shifting through Thermal Energy Storage eliminates a significant portion of your On-Peak energy load by shifting the cooling energy consumption to Off-Peak hours, where energy is cheaper and the grid is under lower demand. This results in lower energy costs, reduced Peak Demand Charges, and better performance out of your cooling equipment. But the greatest difference between Peak Load Shifting and Demand Response is that it does not affect your day-to-day business operations. Lights do not have to be turned off, equipment does not need to be shut down, and occupant comfort does not have to be compromised. By running your cooling equipment at night and storing that energy, your chillers and cooling units can stay shut off during the peak hours of the day without affecting your occupants' comfort.
- How do I sign up?
Click on How to Apply for a Site Feasibility Checklist to see if your site qualifies for the program. Better yet, give us a call at (800) 704-5161 and tell us about your opportunity — we'd love to help.
- How much will I save?
Potential savings can be recognized from 2 sources: Rebate Incentives and Energy Savings. Rebate Incentives are based on the amount of Peak Demand Load (in kW) that is shifted, at a potential total savings of $2,000 per kW shifted.
Energy Savings can vary widely from project to project, but cooling costs can be reduced by 25% or more. Give us a call at (800) 704-5161 to get in touch with a Project Developer who can help evaluate the potential savings available for your site.
- Do I qualify?
You are eligible to enroll in the program if you meet the following requirements:
- PG&E Direct-purchase, bundled customer
- Have a peak load shifting opportunity
- Have peak load dependent on outside air temperature
- Comfort cooling driven
