Just an update on my numbers....a few days from including my May-June bill or I'd have another data point, but oh well:
Average 2023 March-July (pre-solar)
Distro: $26.50
Trans: $23.25
Local: $18.23
Average 2024 March-July (solar)
Distro: $28.35
Trans: $14.65
Local: $9.45
So again I'm still not sure why distribution charge is slightly higher/basically the same, while the other 2 fees drastically dropped.
The fact that the Transmission charge dropped so much - my HUNCH is that the 'consumer' pays that charge. So when you sell to the grid you do not pay transmission fees. Otherwise with the solar I produced last month+my draw, I FAR outpaced my average and it should have been an otherwise expensive month if I paid to push my energy to the grid.
Transmission charge last month: $10.84cents. 262kWh drawn from the grid, 242.5kWh self produced and consumed, 481kWh pushed to the grid.
And using the above math 0.042094/kWh for transmission charge, my 262kWh = $11 and I paid $10.84. Think that's proof you don't pay transmission on pushes.
If we do the same for the distribution charge - I paid $26.93 last month. Using my 262kWh consumed from grid you get $3.41. Then + 30 day fee@0.6479/day = $19.44, so $22.85 total...below what I paid. But if you use the 262kWh consumed from grid + the 481kWh we pushed to the grid you get $9.68. That added up is $29.12...over what I paid. So basically I suspect I'm incorrect here somewhere, either my fee values, or not understanding what is included in that 0.013033/kWh calculation. Requires more digging
