I have NYSEG and here is a pretty typical month (rates based on my February bill):
Day usage - 200 kWh @ 10.9 cents/kWh (supply and delivery) + 2.0 cents/kWh (transition charge, NY state assessment, SBC/RPS charge, merchant function charge)
Night usage - 230 kWh @ 7.6 cents/kWh (supply and delivery) + 2.0 cents/kWh (transition charge, NY state assessment, SBC/RPS charge, merchant function charge)
Basic Service charge = $15.40 (averages out to 3.6 cents/kWh)
So, total Daily Usage Rate = 16.5 cents/kWh (3.6 cents fixed, 12.9 cents variable)
and total Night Usage Rate = 13.2 cents/kWh (3.6 cents fixed, 9.6 cents variable)
I just noticed that my rates have gone done - NYSEG used to offer a fixed pricing plan, and they don't anymore. Everyone is now on a variable pricing plan. What this means is my winter rates will be lower when they have excess power, and my summer rates will be super high, likely, when there are power peaks.
I typically use 430 kWh/month in the spring, summer, and fall - maybe 70-100 kWh more in the winter (boiler pump, wood stove blower, incoming cold water is colder). Just my wife and I, no kids. We have an electric range/oven, electric hot water, dishwasher, etc. Only heat is non-electric. We dry our clothes on a clothesline in the summer and in the winter near the woodstove or outside. We take short showers (~5 minutes or so). There are no phantom loads - everything is power-stripped (a Kill-a-Watt meter will help you understand how much everything draws when it is off, and it is a lot more than you think). All of our appliances are Energy Star rated. We have a front-loading washer (saves a ton on hot water), a new 18 cubic foot basic fridge (saves 100 kWh/month over the older 25 year old model it replaced), CFLs nearly everywhere, laptop (not desktop computers), stereo equipment, and a modest-sized LCD TV (which doesn't run that much). We have village water, so there is no well pump.
Most of the night usage (80% of it, or 190 kWh) is the hot water heater. So realistically, if we eliminated that somehow, we would be down to 240 kWh/month.
