Here's a list of city chargers, which seem priced lower than average. https://www.sandiego.gov/sustainability/clean-and-renewable-energy/evcharging
Interesting development, SDGE is now offering EV-TOU5 plan which add $16 base per month, but drops super off peak to 9c per KW. Using this will require level 2 charging though, but this gives me another and viable option and not depend on unreliable 15c per PW at work. This also means I won't have to rush and install solar.
