On kWh costs, don't forget that when you reduce use, you reduce the last kWh first. Meaning, in a tiered pricing model, you reduce your most expensive electricity first.
So, the price you would use to calculate savings is not your average price / kWh. You should use your max price / kWh.
That's also why if/when you install solar panels on your roof, you recover your investment faster if you don't quite cover your entire electrical needs.
- ams6110 13y agoWho pays variable rates in a residential setting? I pay a flat $0.095/kWH regardless of time of day, demand, etc.
- nwenzel 13y agoI do. Sample size = maybe 3 (I've moved around a bit). I'm in the US, have lived in Southern California (Edison Electric), Phoenix (SRP?), San Francisco (PG&E), and Boston (NStar pronounced N-Staaahhh by my Mass. friends). I thought all utilities were on a tiered pricing model. It's actually a technique employed by Arcata, CA to fight pot growing houses [1][2] that use > 600% of the baseline usage. Also, I have lived places where middle of the day pricing is higher. My utility company just sent me an offer for tiered pricing by time of day. Smart meters help with implementing time of day pricing.
