There are two separate Base agreements: the battery agreement and the retail energy provider agreement.
Here’s what it means to sign up with Base:
Base will become your energy provider for the life of the battery and will renew your energy rates at a price below the market average.
Base can access the battery when necessary and handles maintenance and warranty issues. All applicable warranties from the installer and manufacturer are transferred to you.
If you move, you can transfer the agreement to the next homeowner at no cost to you or them.
Since Base is in Beta, backup energy should not be used for life-critical devices and cannot be guaranteed.
You will incur fees if the battery is stolen or damaged.
If you ever want to cancel with Base, you only have to pay a $250 deinstallation fee. You don’t have to pay for deinstallation if you move after 5 years, transfer the agreement to the next homeowner.
