Been lurking the forums for a while but just registered to pass along some great news for all you owners hoping for the Louisville Supercharger to be open for Christmas...
I just spoke with two of the workers at the site and asked about estimated completion date. Their answer: IT WILL BE POWERED UP BY THE END OF THIS WEEK! I asked if that meant it would be ready for cars to be charged there and they clarified that although it will be powered up by the end of the week, there will still be dirt and construction materials on the site. He stated that by middle of next week, it should be operational for charging. MERRY CHRISTMAS!
Note: I work nearby and will check the status daily to let you all know for sure when it's actually operational. Stay tuned.
