[CA] NEM 1.0 and TOU plan changes
Hi everyone,
My parents just purchased an EV, and they expect their energy consumption to increase by a large margin. I'm trying to help them figure out a long-term solution. Here are some facts about the current situation:
- They have a 7.5 KW PV system that has been overproducing by a large amount for the past few years.
- They're under California's NEM 1.0 plan, using the domestic (tiered) rate plan. They expect the EV consumption to take them out of tier 1.
- They can add some panels (at most 3), but it'd likely make them lose NEM1 grandfathering (my understanding is that upgrades can't be more than 1 KW or 10% of the existing system)
I've a few questions:
1) Under NEM1, can they switch to a current TOU plan and not have to migrate to NEM2?
2) If they switch to TOU, how are credits generated? Are they dollar-per-dollar or kWh-per-kWh?
3) My father is hesitant to switch to TOU because their energy consumption is relatively constant throughout the day. They're always running the AC. Is it ever profitable to be in a tiered plan with solar?
4) Anyone using TOU-EV-1 with solar?
Thanks!
