Quick question on a K-12 district audit. Their demand peaks happen right at 3:30pm when school lets out and all the HVAC systems ramp up to cool down the buildings. Summer months are hitting 800kW demand but winter drops to 200kW. Should I be looking at time-of-use rates or is straight demand billing better for this profile?
School district demand charges - timing question
What utility and what's their current rate? Schools usually do better on TOU because their peak usage is after the utility peak period. That 3:30 spike might miss the peak window entirely.
It's ConEd in Westchester County. They're on SC-2 general service right now. Peak demand charges are killing them June through September.
Definitely run the numbers on TOU-GSD. ConEd's peak period ends at 6pm so that 3:30 spike should be off-peak. Could save them serious money during the school year.
