Some highlights of the Tesla Energy plan below

1. Overview

The Tesla Energy Plan is an energy tariff specifically designed for Tesla vehicle owners who have solar panels and Powerwall installed in their home, offering 100% clean electricity and savings of up to 75% compared to Big 6 tariffs, based on electricity consumption of 8,000 kWh/year. Electricity bills will differ based on usage.

  • Power your home and EV with 100% clean energy
  • Reduce your electricity bills
  • Support the grid when it needs it most
  • Reduce reliance on the grid
  • Protect your home from power cuts
  • Be part of Tesla's first UK Energy Community
  • Receive introductory offers

If you purchase a new Powerwall, you will receive £200 credit on your account or approximately 8,000 home charging miles*. If you already have Powerwall installed, you will receive £50 credit on your account or approximately 2,000 home charging miles*.

*Based on an electric vehicle efficiency average of 0.3 kWh/mile. Efficiency differs depending on multiple variables, such as driving conditions and Tesla vehicle configuration.

  • No daily standing charge on your bill
  • 24/7 import rate of 8p / kWh - the lowest flat rate tariff available in the market (as of June 2020)
  • 24/7 export rate of 8p / kWh for any electricity you export - 30% more than the highest flat S.E.G. tariff on the market (as of June 2020)

2. Savings

With Tesla Energy Plan, solar panels and Powerwall, you could reduce your electricity bills by up to 75% compared to Big 6 electricity supplier tariffs. This is based on a household without solar panels consuming 8,000 kWh/year from the grid.

Your individual savings will depend on a number of factors, including your current energy supplier and tariff, your consumption and how many solar panels you have.

3. Eligibility

You are eligible if you have:

  • A Tesla vehicle
  • Electric Vehicle Charger installed at your home or are able to have one installed
  • Solar panels and Powerwall (Or a home suitable for this)
  • Residential electricity supply

To be eligible for the Tesla Energy Plan, you must have both solar panels and Powerwall installed.

To install solar panels, ideally you’ll need a minimum clear space of 24 square meters – about the size of a parking space – available on your roof. The area should be free of shading from trees, chimneys or other buildings for most of the day to get the maximum energy generation from your panels.

A Tesla Energy Advisor can help assess system sizing and provide a quote on solar and Powerwall.

Moving to the Tesla Energy Plan means:

  • Generation Tariff - your payments for energy generation remain the same. You will not lose your generation tariff, which accounts for the majority of your FiT income.
  • Export Tariff - you will be required to opt-out of your 'deemed export' payments. Instead, you will receive 8p/kWh for every kWh actually exported, this is measured by your Smart Meter.

Note: There is no requirement to switch your FiT generation contract to Octopus.

If you have installed solar after 1 April 2019, we will still require a copy of your Microgeneration Certificate Scheme (MCS) certification in order to get you onto the Tesla Energy Plan. Whether you have installed solar before OR after 1 April 2019, we still require a copy of your MCS certificate.

4. System operation

Tesla need to control your Powerwall to manage how and when you use your solar energy and what you’ve stored. This helps reduce the wholesale market cost of the electricity you consume, giving you the best rates available, as well as supporting the grid during peak periods.

This import and export management is what allows us to be able to give you the lowest flat rate tariffs on the market.

Import and export activity will be determined by our software and will happen automatically. We bases this on factors like historical energy use patterns, solar generation forecast and wholesale energy prices and will constantly optimise grid import and exports to maximise your electricity bill savings.

Tesla’s software uses combinations of your historical energy use patterns, solar generation forecast and wholesale energy prices. This includes:

  • Topping up your Powerwall with surplus solar energy from your roof and 100% renewable energy from the grid when prices are low
  • Selling excess energy from your solar and Powerwall to the grid when demand is high

This will likely result in higher import and export energy volumes than those you see now with standard solar self-consumption and Powerwall, but with 8p per kWh rates to and from the grid, the valuable support you offer the grid comes at no cost to yourself.
