So I was looking online and saw this quote: "A proposal to update the Net Energy Metering program for customers that install rooftop solar beginning Jan. 1, 2018, and to create a "grandfathered" transition period for current NEM customers."
Trying to figure out how the transition from "grandfathered" to new NEM rules might apply I found some other interesting tidbits.
There was chart (attached) that shows how solar has modified TOU times here in Nor. CA. The CPCU concluded that "TOU peak periods currently in effect should be shifted later in the day." They also mentioned the solar has increased the availabilty of energy during the afternoon and decreased the load on the grid, resulting in the shift.
With this they are shifting to Time-of-Day (no more TOU with SMUD going forward) times forward one hour, from 4-7pm to 5-8pm.
And I found the new NEM / Solar rules, my brief summary:
1. Existing Optional TOU will be renamed Time-of-Day (4-7) eff 7/1/17
2. This rate will be only for solar and PEV owners
3. If on NEM before 1/1/2018 and enrolled in residential Legacy or Time-of-Day (4-7) rate plan, customer may remain on either of them until 12/31/22. (Grandfathered)
4. If grandfathered customer on either plan elects the new Time-of-Day (5-8) or the New Fixed plan, they cannot return to the Legacy Fixed or older Time-of-Day plan (4-7).
5. Grandfathering ends on 1/1/23
6. New solar after 1/1/18 will no longer have a fixed rate choice, just the new Time-of-Day (5-8) plan.
So it sounds like there will be four choices over the next several years:
New Fixed Rate + Eff 9/1/18
Legacy Rate + Eff 1/1/17 + Expires on 12/31/22
TOD (4-7pm) + Eff 7/1/17 + Expires on 13/21/22
TOD (5-8pm) + Eff 1/1/18
I also noted that they will be removing the billed solar surcharge as they met the $ quota, They also will be surpassing the 5% solar sourcing requirement to change the NEM rules shortly, even though there are not any major suggested changed to NEM except as noted above.
I guess with all that, calculations will need to be done to see which of the older rate plans will be better for us. Which is hard math for me.
