Tesla applied for a permit to install the following at the Dublin service center address, permit # BLDG-2019-02017.
"Installation of new 1338 kWh battery energy storage system, new concrete slab with energy storage equipment and extended electrical equipment enclosure with new access gates."
That's a big battery to add to the service center, equivalent to about 100 Powerwalls. Curious to see if it will be used to upgrade Dublin to V3 SuperChargers or something else. We'll see if any other permits pop up.
