SDG&E has their own rate plan simulator. But it only works if you’ve had service for a year, with no significant changes in usage. I recently purchased my house, added solar and am about to take delivery of a Model S LR. So the SDG&E simulator can’t help. Looking for a third party simulator that would allow me to input estimated usage and generation so I can compare rate plans. I tried googling but struck out. Anyone know if this kind of tool exists?
