Working with a client in northern Illinois served by ComEd. They're on Rate RDS but I think they qualify for Rate RHDS with much better demand charges during off-peak hours. Client operates primarily nights and weekends which should be perfect for time-of-use optimization. ComEd customer service is clueless about their own rate schedules.
TOU variants not applied correctly by ComEd - missing out on better rates
Tony V. - ComEd has several TOU variants that aren't well publicized. What's the demand profile looking like? RHDS requires minimum demand thresholds and specific usage patterns. Also check if they qualify for the real-time pricing option RTP which can be even better for night/weekend operations.
Lorraine B. - demand runs 180-220 kW consistently. Usage is about 70% during off-peak hours. RTP might be too risky for this client but RHDS looks promising. The peak demand charges are $4.50 lower per kW compared to standard RDS rate. Any tips on getting ComEd to actually process the rate change application?
Tony V. - ComEd can be slow on rate changes especially the TOU options. I've found better success contacting their large customer service group directly rather than going through standard customer service. Those usage patterns sound perfect for RHDS. Make sure to include 12 months of interval data showing the off-peak concentration.
Jim W. - great suggestion on the large customer group. Got transferred to an account manager who actually understands the rate schedules. Submitted the RHDS application with interval data analysis. Estimated monthly savings of $850-1,200 depending on seasonal usage patterns. Fingers crossed for approval.
