Previous proposals would have required everyone to provide income data to their utility which the utility would verify “somehow” (never fully articulated AFAIK)
The latest proposal (which has been accepted by the CPUC) has fixed charges applied for everyone (much lower than previously proposed fixed charges) with discounts available based on existing low-income programs ( https://www.pge.com/en/account/billing-and-assistance/financ... )
So yes in order to get the discount low-income customers need to declare income and may need to verify that income with tax documents (depending on how much fraud these program plan to tolerate) but other customers do not need to provide income information.
