Linda P. in Madison here but working on a Chicago client. I've been through ComEd's tariff book three times and keep finding new riders I missed. Beyond the obvious delivery charges, I've found the Rider EDA (Energy Efficiency and Demand Response Adjustment), Rider PE (Public Purpose Program), and something called Rider REP. Are there other riders buried in there that significantly impact total costs? This client's bills are running 40% higher than my initial projections.
Hidden Riders in Illinois ComEd Tariffs
Randy here. Illinois deregulation created a mess of riders and adjustments. You mentioned the big ones but there's also Rider SMP (Supply Market Participation), Rider RES (Renewable Energy Standard), and don't forget the state and municipal taxes that get rolled into the tariff. ComEd's Rate Schedule delivery charges are just the starting point. The ICC approves new riders regularly so always check the most recent tariff effective dates. What rate schedule is your client on?
They're on Rate BESH (Business Energy Savings Hours). The Rider SMP you mentioned shows $0.00468 per kWh which adds up quickly on a 150,000 kWh monthly account. I think I was looking at an outdated tariff book initially. Where do you typically find the most current rider schedules for ComEd?
Marcus T. from Dallas but dealt with ComEd when I worked in Chicago. The ICC website has the official tariffs but ComEd's business website usually posts rider updates faster. Also check for any pending rate cases - Rider adjustments can change with 30 days notice. BESH is a good schedule but those riders definitely add up.
Found the current riders on the ICC site. Total impact is about $0.015 per kWh when you add them all up. That explains the 40% difference in my projections. Thanks for pointing me in the right direction. Illinois deregulation makes these tariffs incredibly complex compared to traditional bundled service.
