Tesla announced the Megapack today – as a potential replacement for “peaker” power plants, which help the grid when it’s overloaded. Pacific Gas and Electric (PG&E) will deploy several Megapacks at Moss Landing on Monterrey Bay in California. There are also three other locations PG&E are looking at optimising.

The Tesla Powerpack, released in 2015, is Tesla’s current offering for large scale energy storage – the array in South Australia has a capacity of 129 MWh and can deliver 100 MW of power.

The Megapacks are substantially more powerful – each Megapack can store up to 3 megawatt hours (MWh) of energy at a time, and it’s possible to string enough Megapacks together to create a battery with more than 1 GWh of energy storage, according to the press release.

This gives the product comes with some serious grunt: “A 1 Gigawatt hour (GWh) project provides record energy capacity—enough to power every home in San Francisco for 6 hours.”

“Every Megapack arrives pre-assembled and pre-tested in one enclosure from our Gigafactory—including battery modules, bi-directional inverters, a thermal management system, an AC main breaker and controls. No assembly is required, all you need to do is connect Megapack’s AC output to your site wiring.”

According to The Verge, Tesla has been deploying record numbers of Powerwalls and Powerpacks in 2019 – which has created issues with battery shortage, undoubtedly a pain for anyone wanting to order the Powerwall 2 in Australia, for example: 

“Tesla deployed 415 MWh worth of Powerwalls and Powerpacks in the second quarter of 2019, a record for the company. Throughout 2018 and into early 2019, the company had to scale back the number of Powerwall and Powerpack products it deployed because it needed the batteries to support the dramatic increase in Model 3 production.”

Is it going to be easier to wait for the Powerwall 3? Watch this space.

Tesla in 2019 – What to expect – solar implications.

Tesla in 2019 – As the company rockets towards uncharted waters it’s very difficult to predict what Tesla will do in 2019. 

Tesla in 2019 – What to expect – solar implications?

Electrek are reporting that Tesla announced they are unveiling the Model Y solar car on March 14 – an ‘all-electric crossover based on the Model 3’. It’ll be announced in Los Angeles at Tesla Design Studio in Hawthrone, California. 

A shareholder’s letter released last month for Q4 2018 notes that ‘volume production’ of the Model Y should commence by the end of next year (and it’ll probably be done at Tesla’s Gigafactory 1 in Nevada).

“Additionally, this year we will start tooling for Model Y to achieve volume production by the end of 2020, most likely at Gigafactory 1.”

Tesla confirmed their plans for Model Y production at Gigafactory 3 in China at a ground-breaking ceremony back in February.

Although the Tesla electric cars aren’t necessarily to do with solar power per se, Tesla’s impending success or lack thereof relies fairly heavily on these devices. CEO Elon Musk needs the electric cars to succeed to ensure the company has enough money to work on its myriad other projects. They have a lot of competition from other manufacturers such as Mercedes-Benz and Audi who will likely announce their electric automobiles this month.

Some concerns are the Model Y totally cannibalising the Model 3 sales – with the $35,000 Model 3 and the Model X now only available online to lower costs for the financially embattled company. Their shares fell almost 10% last Friday amidst the slew of announcements. 

With regards to solar, Tesla’s main projects are the Powerwall 2, the Tesla solar roof, the commercial scale solar battery storage Tesla Powerpack 2, and potentially the announcement of a Tesla Powerwall 3 release date. To be frank it’s a bit concerning to see all the blood in the water around Tesla right now – let’s cross our fingers for some great results in 2019 for the company.

Tesla in Australia 2018/2019 – Facts & Figures

Tesla have announced their Q2 earnings which notes that they have a ‘crazy’ growth outlook despite cell shortage and a slow deployment of their solar roof. Tesla in Australia is still very far behind the USA, but what can we expect the future to bring?

Tesla in Australia – 2018/19

What can Australians expect from Tesla over the next financial year? We’ve had an agonisingly slow rollout down under and there are many people waiting to see how long it takes for the solar roof to make its way out here.

With the cell shortage that has crippled availability of the Tesla Powerwall 2 in Australia, is it worth waiting for the Powerwall 3 instead? There hasn’t been any announcement yet so it really depends on your personal situation. 

The Tesla Gigafactory in Buffalo, New York is in working on speeding up production of the Solar Roof. They hope to produce 1 GW of solar products at the site annually beginning in 2019, and Tesla has said that it could even reach 2 GW/year down the track. The Gigafactory produces standard solar panels, along with the Solar Roof.

So if you have a bit of patience and are happy to wait until 2019, it’s fine to wait. Solar batteries still have a bit of a ways to go before they are a no-brainer for people to install, let alone the solar roof. But in the meantime, there are certainly solar roof alternatives like the Tractile solar roof tile or the Sonnen/Bristile partnership which they’ve called ‘Solartile‘. Have you got any questions or any experience with any of these solar shingles? Please let us know in the comments. 

Where is the Tesla Solar Roof?

We’ve written about the Tesla Solar Roof before – and we’ve also written about its place in the Australian ecosystem, given that they’re rare as hen’s teeth in America, let alone over here. According to PV Magazine USA, it’s probable that the Tesla Solar Roof will not help their bottom line (Energy Generation and Division Revenues) until halfway through 2019 at the earliest. The reasons for this are for safety and the time lag it’s taking to get all their ducks in a row.

Tesla CEO Elon Musk clarified:

“It takes a while to confirm that the Solar Roof is going to last for 30 years and all the details work out, and we’re working with first responders to make sure it’s safe in the event of a fire and that kind of thing. So it’s quite a long validation program for a roof which has got to last for 30, 40, 50 years, but we also expect to ramp that up next year at our Gigafactory 2 in Buffalo. That’s going to be super exciting.”

According to Musk ‘several hundred’ Solar Roofs have been deployed, are being installed or scheduled for install, and international expansion (i.e. Australia!) is slowly rolling out.

PV Magazine have also written about some of the first solar roof installations in the USA – please click here to read some more about them.

South Australian Virtual Power Plant Launched

Tesla’s South Australian Virtual Power Plant has begun deployment, with the first 100 Powerwalls combined with a 5kW solar array rolling out across a group of South Australian households this month. This rollout is in conjunction with the Household Storage Subsidy Scheme in South Australia.

Housing SA are working with Tesla to install the distributed Powerwall tech which is going to start with a focus on public housing and will end up with arrays and Powerwalls/other batteries (read on to learn about the Household Storage Subsidy Scheme) on up to 50,000 homes. 

Another 1,000 South Australian households will have the Tesla batteries installed before July 2019, but potentially ‘in a few weeks’, according to Electrek. Lots of different figures floating around right now so we’ll update you as we hear more.

It’s actually quite similar to the 100MW / 129MWh Powerpack project in that the whole system will help stabilise the grid and provide a strong baseload of power so we don’t see the blackout issues South Australia suffered through in 2016. In this case it’s not one big project, however – many homes working together will decrease cost of electricity and ensure grid stability improves (and continues to). 

There’s also a separate scheme for other battery subsidies – underwritten by the $100 million Household Storage Subsidy Scheme. The push to help renters and low-income earners enjoy the benefits of solar has been fantastic and we’re excited to see some stats and results after the estimated 40,000 SA households receive on average $2,500 each. Please note that this particular scheme is for people who already have solar power installed and want energy storage as well and is not related to the Tesla virtual power plant.

You can watch a video Tesla released about the South Australian Virtual Power Plant – it’ll explain what the plan is and what we can expect to see next from SA and Tesla!

There’s also a video on Twitter from Nine News Adelaide where the current (Liberal) SA state government seem happy to take credit for this scheme (which was totally organised under the previous (Labor) government). Bit of an eye-roll, but then again it’s par for the course for our beloved Australian politicians.

Regardless of that, the tenant in this video had a $500+ bill for electricity every quarter, which has been reduced to $175 since having the solar system installed. So those are some fantastic numbers!

SA Tesla Battery Plan – Election Fallout

The future of the SA Tesla Battery plan brokered between Elon Musk’s Tesla and Jay Weatherill’s is on unstable footing after the results of Saturday’s state election in South Australia, seeing Weatherill’s party defeated by the Liberals. But will it make much of a difference? How will the new party serve SA’s rapidly growing renewable energy industry?

SA Tesla Battery Plan – What Now?

The incumbent Labor party, headed up by Jay Weatherill, lost to the Liberal party on Saturday night after 16 years of rule in South Australia. The new premier is Steven Marshall who seems quite keen on continuing the Labor party’s work on growing renewable energy in the state.

ABC Radio National Breakfast’s Fran Kelly asked Marshall about the plan to equip housing trust properties with Tesla Powerwall 2 batteries, and Mr Marshall said: “That’s not part of our agenda. Our agenda is 40,000 homes.” However, when pressed about the specifics at a later date, Marshall was a (little) more clear on the Liberals’ plans:

“We don’t know where that is but any contracts the [previous] government’s entered into — we’ll be honouring them, there’s no doubt about that. Any other items that they flagged during the election, we’re happy to look at it but we’ve got our own energy policy agenda and we’ll be rolling that out as a priority.”

We wrote earlier this year about the South Australian solar loan program which both parties had different versions of a renewable energy push for the state – Labor were offering $100m for solar loans in South Australia. Up to 10,000 South Australian homeowners could access up to $10,000 for loans for solar panels, batteries, or both – with the loans interest free for the first 7  years. There was talk of the solar batteries offered in this scheme to be 100% manufactured by Tesla. 

In contrast Steve Marshall’s Liberals had the same amount of expenditure – on a bigger scale, with a smaller amount per household – their $100m plan was to provide grants of $2,500 per household for 40,000 dwellings. Mr Marshall argued at the time that 10,000 households was not enough to ‘shift the dial’, speaking about the rapidly increasing cost of electricity. The Liberals haven’t mentioned Tesla specifically and Marshall doesn’t have the same close relationship as Weatherill had with the enigmatic Elon Musk – but that doesn’t necessarily mean anything. Marshall is clearly keen to move forwards on renewable energy and whether he chooses Tesla or one of the Powerwall 2 alternatives as their energy storage battery of choice may not matter so much.

We’ll keep a close eye on how the Marshall government moves forwards with the SA renewable energy initiatives and keep reporting in!
