Again, only if I import. Or if I am paid in cash.
Under present rules (fairly recent addition), I am paid $0.025/kWh for any net exports during annual true-up. That being average wholesale (for the date of my true-up.)
Note that PG&E voluntarily entered an agreement to pay $0.10/kWh for PV generate power (which of course is only delivered when the sun shines.)
Electrical demand on the grid at Noon, and even more so in the afternoon, is huge.
If not for our PV export, the utility would be buying fuel, or electricity generated with fuel.
PV export is offsetting fuel costs. Depending on what credits are given, that may deprive utility of profit for burning fuel to sell electricity, or it may save them money by providing power cheaper.
Assuming peak demand (A/C) coincides with peak PV production, PV may save utility (or independent generators) capital investment costs. Which is to say, deprive them of the opportunity to invest more in order to make more. PG&E is only allowed profit as a percentage of book value of assets. (Revenue of course is a higher number.)
Net-metering and grid feed could be worked out more fairly. But to do so, PV producers would have to band together and negotiate as a block, with the threat of withdrawing their production (and maintaining their consumption) as a bargaining chip. PG&E would then have to contemplate what it is willing to pay for the power, rather than claiming it is worth less than zero because they once, on a balmy day, paid Arizona to take the last unneeded kWh remaining after all the kWh which were used.
