4 A. Critical Peak Pricing Option Discounted TOU rate + 12 CPP events Overall: Revenue Neutral for the summer PCTs offered for free, but not required PCTs can pre-cool and/or float during events (or not) Settings can be changed by customer at any time Bills showed change in bill relative to standard rate
6 B. Temperature Offset Option Payment ≈ CPP savings for similar AC actions $5 per month for 2-degree AC offset $10 per month for 4-degree AC offset PCTs required Can pre-cool Overrides not allowed (but technically feasible) No $$ incentive to reduce lighting, etc.
