The Tesla Supercharger at the Madonna Inn in San Luis Obispo, California is getting an upgrade.
A brand new Megapack has been installed at the site and is awaiting activation.
According to photos of the recent installation shared by Chad Booker (@bookerc19), the Megapack has been installed behind the 18-stall V3 Supercharger.
This new Megapack will benefit both Tesla and Tesla and owners.
With the massive battery Tesla will be able to gather and store 3.1MWh of energy during off-peak times, like late at night and during the early morning hours when the cost of electricity is the cheapest.
The automaker can then use that energy during peak periods, instead of from the grid, and avoid having to pay higher rates for electricity.
This allows Tesla to save money, and ultimately keep Supercharger rates lower than they otherwise would be.
It is also possible, but less likely, that Tesla could also use the Megapack to provide backup power to the Superchargers in the event of a power outage.
The San Luis Obispo Supercharger is no stranger to Megapacks.
In 2019 Tesla brought it a mobile Megapack with connected Superchargers to increase the number of available stations at the Madonna Inn during the busy Thanksgiving travel weekend.
