Con Edision has a smartcharge program for New York city and Westchester customers. Get PAID (monthly via Paypal) 10 cents per kwh for charging from 12am to 8am, plus $5-$20 bonus per month). For customers on their "Time of Use" plan... pay only 1.7 cents per kwh from 12am to 8am (plus supply charge, I buy from ESCO at fixed 8 cents).
They have a long list of supported EVs (including prius prime)... but not Rav4 prime. I just got a SE and called them. They said there're only
4 Rav4 prime owners called... so they have no plan yet to update their system to support Rav4. I thought there're many Rav4 primes sold in NYC... How many NYC owners are interested in joining the smartcharge program?
If their system finally support Rav4 prime, charging at night could be profitable
