Going back, looking thru my bills on sdge.com, I see the oct-nov bill had this:
DWR Bond Charge 425 kWh x $.00505 2.15
Summer Electricity Generation 275 kWh x $.07531 20.71
Winter Electricity Generation 150 kWh x $.05583 8.38
So that had both, as it was mostly still under Summer rates.
The previous month had two summer generation figures--because the rate changed, apparently.
I see the Winter generation charge in a bill from Jan 2011, too.
So it's been around for a while. And it seems to be what they charge you for having the power plants generate that power. I guess. In any case, it's a rate multiplied by the number of kwh's I used, so it seems legit.
