I stopped by the Green Energy Outlet on Ilaniwai Street in Kaka'ako today and was informed that there is now a fee to charge at their station. I was nonetheless able to charge for free because I have my own Charge Point card. Apparently if I didn't have my own card they would have swiped it with their card and charged me $4.00 per hour. According to Charge Point I was hooked up for 1:07:15 and drew down 4 kWh. Right now electricity is about $0.32/kWh so the cost to them for the electricity for an hour of charging is around $1.26. The Charge Point web site still lists that station as a free station although the person at Green Energy Outlet assured me it was now listed as a pay station. I'm not sure what is going on here or how it will be resolved but you may find yourself not being able to use this station after hours if you don't have a charge point card with money on it. My card is a free access station only card and it did work today. I mention this because if you were able to use this station before and are counting on using it in the dead of night to get home you could be SOL.
I am changing my charge point card to to one that will work with pay stations so that I can use this one at night if need be. I didn't bother before since this is the only charge point station on O'ahu and it was free. If you do set the card up there is a minimum initial deposit of $25.00 required. I figure it is worth it if I ever actually need to charge after hours I will be glad I have the account. If you don't have a charge point card you can get one from http://www.mychargepoint.net/
The chargers at the Nissan stations are still free and I expect they will remain so since the AV chargers they are using aren't set up to allow for paying customers. That said, the only Nissan Dealer that has a charging station available after hours is King Windward, New City and Tony both have their chargers placed where they can't be reached when they are closed. King Windward closes their parking lot after hours but you can still reach the charger by parking next door and running the cord over the fence. It will reach, I've done it.
