One important thing is the price, which should be locked for 10 years. FPL confirmed this during my calls before I applied for the program, but this information is not even included in the FAQ,
I would take that statement with a grain of salt. The EV charging rates are listed on the official FPL rate sheet. Right now, the off peak rate is listed as zero cents. At any time they request a rate adjustment from the state they could make that rate higher.
I don't think they currently have any incentive to raise that rate, but if, for example, 80% of the cars on the road are EVs taking advantage of this plan, I think there would a lot of pressure on FPL to make some money from the charging of all those cars. There is no immediate need to do that, so I'm not worried about it, but who knows 9 or 10 years from now what the landscape will look like.
