The following information about the Tesla Energy Plan is sourced from the Tesla website and is correct as of September 2019.
What is the Tesla Energy Plan & Powerwall offer?
Tesla is offering South Australian customers a special rate of $3,499 for Powerwall and supporting hardware, plus installation; this is inclusive of GST and includes the home battery scheme rebate. With the offer, your Tesla Powerwall and solar will support a brand-new type of energy plan that offers greater energy bill savings. To access the special rate for Powerwall, you must also sign up to the Tesla Energy Plan.
The plan removes the daily supply charge, providing over $300 of savings per year on average, and offers the lowest energy usage rate available in the market at 31.13c/kWh incl. GST. (with a saving of 35% from the reference price*) and still provides a feed-in tariff for your solar export.
The plan is administered by Tesla’s authorised retail partner, Energy Locals, and connects your solar system and Powerwall to a Virtual Power Plant (VPP) where excess energy produced by your system can be exported back to the grid to benefit both you and the community.
*35% less than the reference price based on 4000 kWh/year on this residential tariff in the SA Power Network region. The lowest annual price for 4000 kWh is $1245. Your bill will differ based on your usage.
How does the Tesla Energy Plan work?
The Tesla Energy Plan works by connecting your solar and Powerwall with a network of other solar and Powerwall owners, all working together as a VPP to provide grid services. This means Tesla will be accessing the energy in your Powerwall to optimise it for every minute of the day, so that we can use this energy where it is needed most and offer you the best energy plan – one with no daily supply charge.
How much will I save ongoing?
The plan removes the daily supply charge, providing over $300 of savings per year on average, and offers the lowest energy usage rate available in the market at 31.13c/kWh incl. GST. (with a saving of 35% from the reference price*) and still provides a feed-in tariff for your solar export of $0.10/kWh.
What is the expected payback period?
Under the Tesla Energy Plan offer, customers can now expect payback periods starting from as low as 5 years. Note that payback periods are dependent on your total (and time of) usage. This payback is based on a customer bill comparison with the Default Market Offer.
Is this offer different to South Australia’s Home Battery Scheme?
This offer compliments the South Australian Home Battery Scheme and subsidy support available (where SA Government is providing up to $6,000 off the upfront cost) when purchasing your Tesla Powerwall. The advertised price of $3,499 is after the subsidy has been applied.
What happens if Powerwall can't be installed at my property?
To be eligible for the Tesla Energy Plan you require a fully installed solar and Powerwall system. If you initially sign-up to the plan, but then subsequently find out that your Powerwall installation cannot proceed for any reason, your Powerwall and Tesla Energy Plan contracts will be cancelled as per the Terms and Conditions and you will remain with your existing retailer.
Will I lose my feed-in tariff on my existing solar system?
In addition to avoiding any form of daily fixed charge, the offer also provides a generous solar feed-in-tariff of $0.10/kWh, plus the cheapest energy rate in South Australia*.
Customers should note that when switching to this plan you will transition away from any retail incentives provided by your current retailer – including any feed-in-tariff being provided, including government sponsored feed-in-tariffs. Your eligibility to receive existing feed-in credits will cease from the date of your application for approval to connect the home battery system is submitted to SA Power Networks.
*Cheapest generally available energy usage rate in South Australia as at August 2019.
Does this offer allow me to live off the grid?
No. A requirement of the South Australian Government subsidy scheme is that all batteries, including Tesla Powerwalls, are capable of being part of a Virtual Power Plant. For this reason, your home needs to be connected to the SA Power Network’s electricity network.
Are the penalties if I want to leave the plan?
So long as you stay on the Tesla Energy Plan for 12 months, you will not incur any termination charge or exit fees. An early termination charge of up to $1200 is applicable should you seek to leave the Tesla Energy Plan before 12 months.
How is Energy Locals involved?
Whilst Tesla manages the VPP component of the plan, Energy Locals will be your retailer and will manage all the energy retail services, including account management and customer support.
What is a Virtual Power Plant (VPP)?
A Virtual Power Plant is created by a network of homes with solar panels and battery storage systems all working together to generate, store and feed energy back into the grid.
Typically, energy from a home’s solar panels and battery system mainly provides electricity for the house on which it is installed. However, energy generated and stored by the system can also be used to provide essential grid services. Tesla can aggregate your system with others and coordinate these services as a VPP to help power South Australia and therefore benefit the wider community – including your friends and family.
All of the VPP operations will be seamlessly controlled using Tesla’s world-leading optimisation software, so you can sit back and enjoy savings on your energy bill.
The aim of the Virtual Power Plant is to maximise the value of your solar and Powerwall system and to help stabilise the grid to prevent outages in your community. This means Tesla will be accessing the energy in your Powerwall to optimise it for every minute of the day, so that we can use this energy where it is needed most and offer you the best energy plan.
A VPP controls each system centrally to support the needs of the grid, similar to a large power station. Sometimes this may mean your Powerwall is charged or discharged differently to how it may operate under individual operation (i.e. if you were not part of a virtual power plant). For example, the VPP may export energy during peak times and provide valuable grid services to keep the grid running. Tesla then passes this value back to you through a lower energy bill.
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, we will let you 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 hours of power.
Your Powerwall will also benefit from our Storm Watch feature, which forecasts severe weather events (the leading cause of power outages) and automatically charges your Powerwall to maximum capacity as protection.
