General Discussion / Considering Charging with Night Time Electricity rates
« on: June 07, 2013, 09:44:25 PM »
My New-Hampshire electricity company PSNH offers "Rate R-OTOD, Residential Time-of-Day Service"
"Available to customers living in individual residences and apartments – varies by time of day.
Off-peak hours: • 8 p.m. to 7 a.m. weekdays • weekends and holidays"
The night electricity is 'free': 0.18 cent/KWH versus 3.9 regular
So by charging EV's overnight, and run washers, dryer, pool-pumps over night/weekend you can potentially save!
The catch is that you pay much more for daytime use :12.5 ( Airconditioners )
And you essentially add a meter for so they charge $28/month versus $12
And there is already and almost 11 c/KWH in fixed items in our fair state.
So I put all of that in a spreadsheet (picture attached) and for me it comes out to 'not worth the risk'
Over the year I use less than 20KWH/day roughly, and expect to add at most 100 charging nights @8KWH
The way I read my spreadsheet is that IF ... big IF ... I can move to less
than 20 percent peak-week-day usage, THEN I can save $10 - $20 on a $130 monthly bill.
Hopefully this helps others thinking about this some!
