Frequently asked questions
What is the Tesla Energy Plan?
The Tesla Energy Plan is an Energy Tariff specifically designed for Tesla vehicle owners with solar panels and Powerwall.
It offers customers 100% clean electricity and savings of up to 75% compared to Big 6 tariffs*. This is achieved through the lowest flat electricity tariffs in the UK combined with smart management of your home’s energy and electric vehicle (EV) charging. Your solar system, Powerwall and EV charging are connected to Tesla’s proprietary platform, optimising your energy costs and allowing energy stored by your system to be exported back to the grid to benefit both you and the community.
The plan is administered by Tesla’s authorised retail partner, Octopus Energy.
*Based on electricity consumption of 8,000 kWh/year. Your bill will differ based on your usage.
What are the key benefits of this offer?
You get to save money whilst transitioning to sustainable energy. Tesla smartly manages your Powerwall and electric vehicle charging to ensure you minimise your electricity bill, and also support the grid when it needs it most, thereby helping increase renewable energy penetration in the system as a whole.
As a special introductory offer, if you sign up and purchase Powerwall by January 1, 2020 you will get a year’s free electricity. Or if you already have a Powerwall, you get 2,000 free miles of home charging for your Tesla vehicle.
What are the details of the tariff?
Tesla Energy Plan is a simple, transparent tariff with the best rates available on the market
- No daily standing charge on your bill.
- Flat import rate of £0.08/kWh - the lowest flat tariff available in the market (as of September 2019).
- Flat export rate of £0.08/kWh for any electricity you export
How does “12 months of free electricity” work in my account balance?
If you buy a new Powerwall (directly through Tesla) as part of this offer, your next 12 months’ electricity bill (up to a maximum of 500GBP) will be free. Your account balance will be credited when you sign up.
How do you work out my 2,000 free miles?
You will get a 50GBP credit on your Octopus Energy account upon sign-up (As long as you are not entitled for the 12 months of free electricity offer mentioned above) We have used an EV efficiency average of 0.3 kWh/mile, so 50GBP home charging on the Tesla Energy Plan equates to ~2000 miles free driving. Just bear in mind that efficiency varies depending on multiple variables such as driving conditions and Tesla vehicle model.
How much will I save?
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 8,000kWh/year from the grid.
Your specific savings will depend on a number of factors, including your current energy supplier and tariff, your consumption and how much solar panels you have.
Am I eligible for this new offer?
You are eligible if you have:
- A Tesla vehicle
- Electric Vehicle Charger installed at your home (or off-street parking suitable for installation of one)
- Solar panels and Powerwall (Or a home suitable for this)
I already have solar and Powerwall. What’s next?
You can transfer onto the Tesla Energy Plan straight away by switching your retail plan.
Additionally, Octopus Energy will arrange the installation of a smart meter at no charge in case you do not have one already.
What if I don’t have solar panels?
To be eligible for the Tesla Energy Plan, you must have both a solar PV and Powerwall system fully installed. We are happy to provide you with a quote for both solar and Powerwall. Households with existing solar systems will also be able to purchase additional solar panels when purchasing Powerwall.
Do I have to own a Powerwall to join the energy plan?
Yes. The Tesla Energy Plan uses the combination of solar with a Tesla Powerwall and electric vehicle charging to provide additional benefits. All customers signing up to the plan must therefore have installed a Powerwall home battery and solar PV before joining.
For customers who are awaiting the installation of their system, we will manage the transfer process once your system is installed.
What happens if solar or Powerwall can't be installed at my property?
To be eligible for the Tesla Energy Plan you require solar panels and Powerwall.
Do I need to have off-street parking to sign-up?
Yes, you will need to have off-street parking with an EV charger to enjoy the Tesla Energy plan. If you do not have an EV charger already, a Tesla Energy Advisor can help you get a Tesla wall connector installed.
What happens if I already have another electric vehicle charger installed, do I still need to have a Tesla wall connector?
No. You will need to disable any smart charging features on your charger if it has those capabilities. This will allow you to use your existing charger for the Tesla Energy Plan.
Do I need a smart meter as well?
Yes, Tesla Energy Plan involves import and export tariffs. Therefore the need to have a smart meter installed. If you do not have already one, Octopus Energy will install one at no cost.
What if I rent my home? Can I still access this offer?
Yes. You don’t have to own the home to access the Tesla Energy Plan. However, you will need to obtain approval from the property owner to have a Powerwall and solar system installed and be able to demonstrate the property owner’s consent to Tesla prior to installation.
Will I lose my feed-in tariff (FiT) on my existing solar system?
Under FiT guidelines, you get paid for being a generator, and paid for whatever you export. If you move to the Tesla Energy Plan, you will still be able to receive your generation payments (the larger component of the FiT, linked to all kWh generated by your solar).
You will no longer be eligible to receive your FiT “deemed export” payments (50% of energy generated). Instead, you will receive 8p/kWh for every kWh actually exported. (Note that you will be required to opt out of your deemed export payments from your existing FiT supplier, but there´s no requirement to switch your FiT contract to Octopus).
If you have installed solar after 1 April 2019, we’ll still require a copy of your Microgeneration Certificate Scheme (MSC) certification in order to get you onto the Tesla Energy Plan.
I’ve just signed up to a retailer, can I switch to this plan now?
Yes, you can. If your house has solar panels, Powerwall and you drive a Tesla vehicle (and have a Tesla wall connector installed) you are eligible for this Tesla Energy plan. The standard 14 business day cooling off period applies between retailers, and Octopus Energy will manage the switch for you.
What happens if I sign up now but then want to leave later? Are there penalties?
If you want to change your offer or move to a different energy retailer for whatever reason at any time (no minimum contract term required) there will be no exit fees or contract lock-ins. That said, the Tesla Energy Plan has been specifically designed to maximise the value of your Powerwall and Tesla are confident that the plan has been tailored to offer the greatest benefit for you.
Does it work with other brands of EV too?
Tesla Energy Plan is only available for Tesla vehicle owners at this point in time. However, if you also have another EV, then Tesla Energy Plan will benefit all your home energy usage.
How is Tesla involved?
Tesla Energy Plan integrates Tesla’s products with an innovative retail electricity plan. Building on its world-leading hardware, Tesla is now using software to ensure you optimise the use of your solar, Powerwall battery system and EV charging so that you save on your energy bills, whilst also providing renewable energy back to the grid when needed most.
How is Octopus Energy involved?
Octopus Energy will provide all the electricity retail services, including account management and friendly customer support. Octopus Energy is a UK 100% clean energy provider renowned for its innovation and industry-leading customer service. You can also get your natural gas from Octopus Energy if you sign up to the Tesla Energy plan, but this is not mandatory.
5. SYSTEM OPERATION
Why do you need control of my Powerwall?
Tesla need to have control of your Powerwall to enable us to optimise how and when you use your solar and the energy stored in your Powerwall to minimise the wholesale market cost of the electricity you consume – i.e. avoiding grid imports when energy prices are high, and even exporting to the grid during peak periods when it makes sense to. This is what enables us to offer the lowest flat rate tariffs in the market.
How will Tesla manage grid import & exports?
Import and export decisions are determined by Tesla’s proprietary software, and based on factors including your historical energy use patterns and wholesale energy prices. Tesla will constantly optimise grid import/exports to maximise your electricity bill savings.
Why are the “Incoming” & “Outgoing” electricity figures shown in my customised Tesla Energy Plan quote so high?
Import and export decisions are determined by Tesla’s proprietary software, and based on a combination of your historical energy use patterns and wholesale energy prices. This includes charging your car and topping up your Powerwall with excess solar energy from your roof, and 100% renewable energy when grid prices are low, as well as selling excess energy from your solar and Powerwall to the grid when demand is high. This will likely result in higher import/export electricity volumes than those expected under standard solar self-consumption Powerwall operation mode.
How does this affect my Powerwall warranty?
The warranty provided by Tesla is not affected under the Tesla Energy plan. Tesla will still warrant that:
- Your Powerwall will be free from defects for 10 years following initial installation date and
- Your Powerwall will have an energy capacity of 13.5 kWh on its initial installation date, and will retain 80% capacity at 10 years following such initial installation date.
What happens during times of grid outage?
Individual Powerwalls have back-up capability as a standard feature to ensure a seamless transition to keep your lights on when there is a grid outage. As part of the Tesla Energy Plan, you will be able to reserve up to 20% of the energy capacity in your Powerwall as back-up. This level of energy reserve provides the typical customer with 2-4 hours of power. You will need to indicate before installation of your Powerwall that you want backup functionality enabled.
