I don't fulling understand the wholesell of 3 cents buy back from SCE.
How does this work?
Currently I am on TOU without solar yet.
Summer rate per kilowatt is:
peak 2 pm to 8 pm = .48 cents
off peak 8 am to 2 pm = .24 cents
super off peak 8 pm to 8 am =.13 cents
Let say the 3.8 (small tesla system) can generate 3.8 kilowatt per hour.
If you use under 3.8 during sunny day, that's all good. Assuming you are producing 3.8 kwh.
If you use over the 3.8, it pull from the grid. The different of going over reflect the time you use and based on the TOU rate as listed above.
Let say you produce more then you use and have a credits.
The credit is only a 3 cents per kilowatt that SCE give back?
What if I using over my 3.8 kilowatt hour during peak time of .48 cents per kilowatt?
The credit will offset the .48 cents by 3 cents?
I thought it's reversing your meter (net metering). Your smart meter has two program ID 082 and program ID 071.
082 is the lifetime meter usages.
071 meter reading is giving back to the grid from solar panels.
If net metering is use to off setting the usage than the TOU rate cost is non factor. Right?
I am waiting for my install so I am basing this on my conversation with the SCE Customer Support Person.
I am the TOU-D-B. See rates below. I requested to keep the plan that I am grandfather until I think 2022. New plans are like 2 rates with peak either 4-9 or 5-8.
My understanding is that I accumulate credits based on when I add them.
Example:
Solar is mostly 10-2pm which is 16 cents. So I would be "banking" credits at 16 cents per kWh. However, whatever credits I add between 2-4pm or maybe 2-5pm I would be producing credits at 48 cents per kWh. Then when I use the credits they would be used at the rate at that time. Say I use them at super off-peak 10 cents per kWh then I would get a lot more kWh at my off-peak rate since I am using them at a lower cost than I created credits for them. I.E. The credits are based on the cost when you use the credits.
NOW.... Annually there is a true up. Meaning that if I accumulated more kWh credits then I used they would be purchased from me at the wholesale rate of 3 cents per kWh. This is a bit confusing because it is no longer based on when I added them but that is what I was told.
You should call your provider to check if what I am saying can be confirmed by a different person. But I am on SCE so they may also be different if you are not with SCE.
