Based on the shape of the precast pedestal bases visible in gummbyjim's picture, this will be a traditional style, 150 kW supercharger. You can also see from the picture that it looks like most of the construction is likely already finished. However, this site may end up having to wait a little while for further progress because Tesla is reportedly experiencing a shortage on the supply of the charging posts. Multiple supercharger sites in Canada and across various states of the US currently seem stalled by this.I believe they are installing a new supercharge location on Staten Island. Its located on the South Shore by Z Two. The Signs are up for Tesal parking only and I believe there are 8 stalls at this location. No chargers are in place yet. (attaching the linked picture below)
