This is pretty lame. The ad hominem is less than informative visa vi the subject of subsidies, and pretty feeble as far as mind reading exercises are concerned. It tells more about state of yours than mine.

If you insist on framing SGIP as a subsidy, it is definitely not the TE greatest, the
PUC Energy Storage Mandate is greater by far.
