WARNING TO PG&E CUSTOMERS: In early 2021 PG&E sent out letters to some customers that have solar electric systems trying to convince them to change to new electric rates. The letter indicates these customers will automatically have their rates changed if they do not reply. The new options are TOU-C or TOU-D.

If you have had your system for longer than a few years, your rate is likely E-1. There is no benefit to changing to the new rates-- it is a scam. If you are E-1, your base rate is about 0.25 per kWh now. With the new plans the rates go to 0.38 to 0.42 per kWH depending on the time of day. They have also tweaked the peak period so your afternoon solar production no longer gives you any leverage. I strongly suggest you mail that flyer back to PG&E by May 18, 2021 and select keeping your existing rate. Do not wait, and scan it with your selection made for your records and check your bill to see you stay on E-1.

If your rate is E-6 and your system is sized properly, you are better off not changing rates.
