Tesla is rolling out a pilot program in the Netherlands that opens 10 Supercharger locations to non-Tesla electric vehicles for the first time.

Non-Tesla drivers that want to use a Supercharger location will first need to download the Tesla app and create an account with the company. From there, they can select ‘Charge Your Non-Tesla,’ search for a location, add a payment method and start charging, according to information on Tesla’s Netherlands website.
