I have what is probably a fairly unique situation. We now have an EV that we charge at home and have decided to upgrade our system to cover the extra load. Need about 1.5 more kW in addition to my current 5.4 kW.
Doing the research, I've discovered if we add more than 1kW, we will be migrated from NEM1.0 to NEM 2, also known as the NEM-ST(Successor Tariff). I've finally managed to figure out how this will affect us as far as the installation fee ($132) and how the non-bypassable charges (NBCs) work (adds about $9/mo to the bill). The only mystery still remaining is the TOU-2 (Time of Use) migration. We are currently on a tiered rate and, from what I've seen, the option to go to TOU is an IQ test, clearly a bad deal since on the tiered rate you rarely if ever reach the second tier, which is less than the TOU peak rate, assuming your system is sized correctly. It appears that 'everyone' will be required to go to TOU by April 2018. But there looks to be an opt-out option if your system is installed before then and you will be grandfathered into the tiered rate for 5 years. What's not clear is whether or not this applies to NEM-2 customers. SDG&E's website is unclear about this and there are a couple of vendor sites on the web that say NEM-2 customers are included.
Should we not fall under the grandfathering with NEM-2, we will probably just add 1 kW and stay on NEM-1. SDG&E refuses to answer the question, claiming final approval won't be received from the PUC until somewhere around December.
The TOU rate would make upgrading the system completely non-cost effective. Anyone have any experience here or more complete info?
Thanks
