Huge portfolio audit - 25 locations across SCE territory. Mix of TOU-GS-1, TOU-GS-2, and TOU-GS-3 rate schedules. Client wants to know if they can get all locations on the same rate schedule for simplicity. SCE has so many rate options it's overwhelming. Where do I start with optimization across this many locations?
Southern California Edison 25-location portfolio challenge
SCE rate optimization is complex because of all the TOU periods and seasonal variations. Create a load profile analysis for each location first. TOU-GS-2 Option R might work for mid-size locations with consistent demand patterns.
Don't try to put all locations on the same rate schedule just for simplicity. Each location should be on the optimal rate based on its specific usage pattern. SCE will usually run rate comparisons if you ask.
SCE's new time-of-use periods that started in 2023 changed the optimization calculations. Make sure you're using the current TOU windows. Peak period is now 4-9 PM instead of the old 12-6 PM.
Thanks for the advice. SCE ran rate analyses for all 25 locations. Found 8 locations that should move to different rate schedules. Potential savings of about $180,000 annually across the portfolio.
That's a great result! SCE rate optimization can be very lucrative once you understand their complex rate structures. The key is matching each location's specific load characteristics to the right rate schedule.
SCE also has demand response programs that might work for some locations. The Auto-DR program can provide additional bill credits beyond the rate optimization.
Large portfolio audits require systematic analysis and clear documentation of optimization opportunities. The key to success is understanding that each location is unique, even within the same utility territory. Standardize your analysis process but customize the solutions. Excellent work on this complex portfolio.
