Energy Value

Installing solar and Powerwall can help save you money by lowering your energy consumption from the grid. The Tesla app can estimate savings from your solar system and from your Powerwall system with the Energy Value impact card.

With the Energy Value impact cards, you can view the amount of value generated on a single day, week, month or lifetime of the system, and you can customize the value calculation to be specific to the cost of energy in your area.

Energy Value
An estimate of the money you didn’t have to pay your utility

For Powerwall Owners

A 360º view of economics — the estimate uses all data available from your Solar generation and Powerwall, Home and Grid usage

Energy Value Estimation

We estimate your Energy Value estimate based on the price of your grid energy. This is based on your rate plan or tariff, found on your utility bill. Follow the steps to add a utility rate plan to configure a rate plan for your system.

The Value estimate is calculated from all energy data Tesla has available for your home in the selected period: Solar Production, and your Home and Grid usage. Energy Value is primarily influenced by your solar production, and — if available — your grid imports and exports throughout the day but also accounts for the value that your Powerwall earned by storing excess solar energy produced during off-peak hours and using it during the most expensive hours of the day, also known as load shifting.

Feature Availability

The Solar and Energy Value impact card requires the Tesla Mobile App with version 4.2.0. Solar Value and Energy Value are scheduled for a phased global release during October and November 2021. Additional utilities and regions will be added routinely.

Frequently Asked Questions

How accurate is Energy Value?

While we expect these values to be fairly accurate, all values presented in the Tesla app are estimates, not guarantees. These values may vary from other calculations, such as those in your utility bill, for several reasons. These may include factors like aggregation, taxes and local fees, meter inaccuracies, data gaps, energy usage, non-bypassable charges, transmission or service fees, rounding, etc.

If I change my rate plan in the Tesla app, does that change my utility bill?

Changing your rate plan in the Tesla app does not change your rate plan with your utility. Contact your utility if you wish to switch to a new rate. Similarly, switching your rate plan with your utility does not automatically update the rate plan in your Tesla app. You may change rates in the Tesla app at any time.

Can I edit my rate plan to find additional savings with my utility?

You can edit your rate plan in-app to estimate potential value changes when you change your rate plan with your utility. Remember to return to your original settings afterward.

When will my Powerwall get support for rate plan features and the Energy Value cards?

These features are being released on a routine basis as we monitor performance and make adjustments to improve accuracy. As with other software updates, availability of these app features may vary, with a phased user rollout expected through November 2021.
