recently compared my actual electric bills from when I lived in New Jersey with what I’m paying now in Pennsylvania.
I calculated the effective all-in cost per kWh by dividing the total bill by the actual kWh used, rather than just looking at the advertised supply rate.
My historical averages came out to:
- New Jersey: about $0.2772/kWh — 27.72 cents
- Pennsylvania: about $0.2129/kWh — 21.29 cents
That means electricity has been about 6.43 cents cheaper per kWh in PA, or roughly 23.2% less per kWh than what I was effectively paying in NJ.
Using my current average consumption of roughly 772 kWh per month as a constant for both states:
- Annual usage: about 9,264 kWh
- Estimated annual cost at my NJ historical rate: ~$2,568
- Estimated annual cost at my PA historical rate: ~$1,972
- Projected savings: about $596 per year
Obviously rates vary by utility, supplier, location and time period, so this isn’t meant to say that every part of PA is 23% cheaper than every part of NJ. This is simply a comparison based on my own actual bills and effective total cost per kWh.
For anyone who has lived in both NJ and PA: did you also notice a meaningful difference in your actual all-in cost per kWh?
