Thanks, Miimura! I was certainly reading the E-TOU option A chart incorrectly. My usage will be in tier 2 and the costs per kWh will be between 22 and 35 cents each.
The formula for calculating Option A TOU customer costs is confusing to me: (Advice Letter 4769 page 14)
"Total bundled service charges shown on customer’s bills are unbundled according to the
component rates shown below. Where the minimum delivery bill charge applies, the
customer’s bill will equal the sum of (1) the minimum delivery bill charge plus (2) the
generation rate times the number of kWh used. For revenue accounting purposes, the
revenues from the minimum delivery charge will be assigned to the Transmission,
Transmission Rate Adjustments, Reliability Services, Public Purpose Programs, Nuclear
Decommissioning, Competition Transition Charges, Energy Cost Recovery Amount, DWR
Bond, and New System Generation charges base on kWh usage times the corresponding
unbundled rate component per kWh, with any residual revenue assigned to Distribution.*"
This looks like the same way of charging me that I experience now with my solar panels.
On January 1, 2020 the Option A TOU time periods (peak is 3:00 pm to 8:00 pm) will be identical to the time periods shown for Option B. The Option B peak periods are 4:00 pm to 9:00 pm.
Option B is non-tiered. It is limited to 225,000 customers.
PG&E is shifting toward fewer tiers of usage with most households paying more money especially during hours of peak demand. Using battery storage of solar electric generated power can relieve demands for electricity at night. Like most Californians with solar panels, I use a considerable amount of electricity in the evenings. I will not be able to escape that usage pattern.
Have any forum members installed the big battery packs yet? What is your experience with your expenses for using these for power during times when solar panels are not generating much electricity?
