My panels produce surplus from 9am to about 5pm. PG&E is forced to give me credit for that excess, even though there is a glut of solar during that period. TOU updates mean they have a bigger window to charge me double when I start pulling power later in the day. Thing is, ALL consumers are paying that higher rate. Keep in mind, at 3pm PG&E probably pays $.03 per KW but the credits I rack up are worth 10x that
This is a regressive policy because people with money can buy solar and save. If the TOU adjustments cause trouble they can supplement a battery to their system to let them always target the low cost periods. It is a positive in the sense it promotes efficiency and helps flatten the curve. The regressive part is that lower income households will end up covering a good part of the subsidies
I remember hearing someone posting the issue in NV in the past. The power company basically reset their policy to limit the net metering benefit (aka free battery). They were allowed to do so because they were losing money.
