Awesome!I was curious and went to look at PG&E's earnings report for the last quarter. Unfortunately it isn't broken out between residential and commercial customers, so for a worst case analysis I am using the 4.8 million residential accounts + 0.6M commercial accounts number that they publish and lump them together as 5.4M accounts. Commercial numbers should be larger than residential, so this is a worst case for just us residential people.
In the case of the operating and maintenance portion it isn't split between electric and natural gas, so you can't assign it all to electric.
- Electric Revenue - $3,690M = $227.78/month/account
- Cost of Electricity -$780M = $48.15/month/account
- Operating & Maintenance $2,291 = $141.42/month/account
So taking a swag I will say that the operating and maintenance is split 70% electric to 30% natural gas. This would take the electric portion from $141.42/month/account down to $98.99/month/account. How much of that should be a fixed fee? I think maybe 50%, so that would be $49.50/month. Realistically this should maybe be 25-30% lower with commercial accounts paying a significantly more than a single residential account.
- Natural Gas Revenue = $1,428M = 27.9% of Total revenue
- Cost of Natural Gas = $359M = 31.5% of cost of electric + NG
Thanks! I think that we agree on the grid costs being WAG in the ballpark of $140-$190ish, on an average account basis that was computed two very different ways. (I am ok with a grid cost estimate of $190/mo.) I also agree that the actual number might get scaled down when commercial is billed at a different "grid fee" rate(s), recognizing that a barbershop and a data center have very different grid loads and stresses.
Good enough to start with as far as I am concerned. I was just trying to point that expecting Hawaiian HECO $26/mo rate was perhaps not reflective of the California realities.
All the best,
