Effective April 2016 Alliant energy headquartered in Madison WI, who services my area of IA just started a $500 rebate on the cost of charger installation. I think I will have to install a second one...basically wont cost me much, but wish they had last year! Here is the link: http://www.alliantenergy.com/AboutAlliantEnergy/EnvironmentalCommitment/Vehicles/200207?WT.mc_id=AEBannEVChargerRebate . Anyone else get a rebate for charger install?
