Permanent Load Shifting (PLS)
Substantial Energy Savings for Refrigerated Spaces
Permanent Load Shifting (PLS) is a “proactive” electric load reduction program that can deliver large and persistent energy savings to industrial manufacturers, particularly those operating refrigerated facilities. Unlike Demand Response programs, where customers “reactively” reduce usage for short time periods when requested by their utility, customers utilizing PLS enabling technologies shift their energy usage from peak time periods when rates are highest, to mid- and off-peak periods when rates are lower, for the entire peak energy season. The result is substantial energy savings, giving participating companies a competitive advantage versus those that only participate in Demand Response programs.
EPS Corp has extensive experience and expertise in these programs. We pioneered the program for San Diego Gas & Electric (SDG&E) and successfully implemented PLS at three of their larger industrial refrigeration customers with the following significant results:
Customer Benefits
- Within the first 15 months, the program yielded total savings of almost 1.5 MW
- Combined energy savings and financial incentives for the three companies totaled over $450,000
- A constant and predictable load shift without impacting operations
Utility Benefits
- Within the first 15 months, the program shifted almost 1.5 MW to off-peak periods
- Manageable demand load during peak periods, reducing the risk of power outages
- Incentive program effectively marketed and implemented at large customers with minimal resource requirements by the utility
