Run an extension cord to a place without Coned.
In all seriousness, it is about 25 cents a kWh in NYC. I live in Nassau County and it is high there, at about 19 cents. I know there is a program where you can get a 5 cent rebate if you agree not to charge during peak times. I would check their website. Even with that, the price is still really high and the voltage in NYC is relatively low. I get around 210 but I have heard there are parts of the Bronx that cap out between 180 and 190.
