check page 15 of the CA PUC document linked. it's the 2022 report for FY2021 so it's not exactly current, but close enough.if that “is” the accurate gen cost, let it sink in, and one can see why the new proposals have a seemingly high access fee and 30%+ less kWh cost.
Also makes the case for those who say Nem less than 3 was unfairly profiting home Solar users, and by extension, home Solar installers.
interestingly, costs have been declining for 3 of the 4 electric utilities in CA. SDG&E is the outlier.
you can dive as deep as you like into this, and it's not simple to carve out costs since so many are burdened with additional regulatory, distribution, etc costs.
But the generation costs are separated out in Figure 1.2 and Table 1.9, and do show 6-8 cents average generation cost per kWh in CA.
that's the max cost that the utilities should be paying for solar buy-backs. all the other burdens are similar or the same.
any amount higher amounts to an un-taxed subsidy.
