Tesla Powerwall 2 gets included in Australia’s battery subsidy plan for 40k homes

Published

on

In a rather ironic twist, Tesla and its Powerwall 2 battery have been added to the list of choices for South Australia’s Home Battery Scheme, which aims to provide subsidies to 40,000 homes. The inclusion of the Powerwall 2 battery to the subsidy scheme comes amidst the ongoing progress of Tesla’s ambitious Virtual Power Plant in the region.

The update, which was recently reported by One Step Off The Grid, noted that Tesla’s 13.5kWh lithium-ion home battery systems are now eligible for the full AU$6,000 (US$4,300) subsidy offered by the SA government. As an additional means to attract buyers, Tesla has set up a temporary stall at the Rundle Mall in Adelaide, to showcase its battery storage technology. As noted by the Australian-based publication, though, customers are being informed that the installation of Powerwall 2 batteries would likely involve a lot of waiting.

Solar Quotes’ Ronald Brakels, who visited the Tesla pop-up store, was reportedly informed that there is an estimated 12-week waiting period for Powerwall 2 batteries. Brakels further added that he was quoted AU$9,300 (US$6,600) for the Powerwall 2 and the installation after the AU$6,000 (US$4,300) subsidy is applied. That’s still a substantial amount, and would likely be out of reach for some homeowners who are in need of a system that can lower their power bills.

This was among the concerns that were raised last year when South Australia’s Home Battery Scheme was announced as a possible replacement for Tesla’s Virtual Power Plant project. Not long after he was elected, South Australia premier Steven Marshall expressed his opposition to Tesla’s proposal of establishing a 250 MW/650 MWh virtual power plant comprised of 50,000 residential homes and Powerwall 2 batteries. As an alternative, Marshall proposed a subsidy program instead, which would lower the price of battery storage units for 40,000 homes.

“(Former Premier Jay Weatherill) was doing (Tesla’s Virtual Power Plant) for Housing Trust homes in South Australia… That’s not part of our plan. What we are going to do is provide a subsidy to get (those with) solar rooftops systems with some storage capacity,” Marshall said before shortly before he was sworn in last year.

Marshall’s plan had stark differences with Tesla’s plan for a Virtual Power Plant. For one, the battery subsidy would be offered to homes that are already equipped with solar panels. Apart from this, homeowners would be required to purchase their own batteries, albeit at a discounted price. Tesla’s Virtual Power Plant, on the other hand, plans to provide solar panels and Powerwall 2 batteries to 25,000 Housing Trust households and 25,000 private low-income homes for free.

Seemingly after receiving flak for his lack of support for Tesla’s Virtual Power Plant, Marshall eventually took a softer stance on the project. By the end of May 2018, Energy Minister Dan van Holst Pellekaan announced that the South Australian government would be pursuing Tesla’s Virtual Power Plant and Marshall’s Home Battery Scheme side-by-side.

Since then, Tesla’s Virtual Power Plant has completed its first phase, which involves the installation of solar panels and batteries to the first 100 houses in the system. Marshall’s Home Battery Scheme, on the other hand, was launched last October, and is expected to add up to 400 MWh of storage to the state’s grid when complete. Ultimately, the 400 MWh from Marshall’s Home Battery Scheme would be a nice addition to the 650 MWh of energy storage that would be provided by Tesla’s Virtual Power Plant once all 50,000 residential units are connected and online.

Why SpaceX just made a $60 billion bet on AI coding ahead of historic IPO

SpaceX has secured an option to acquire Cursor AI for $60 billion ahead of its historic IPO.

Published

on

By

SpaceX announced today it has struck a deal with AI coding startup Cursor, securing the option to acquire the company outright for $60 billion later this year, while committing $10 billion for joint development work in the interim. The announcement described the partnership as building “the world’s best coding and knowledge work AI,” and comes just days after Cursor was separately reported to be raising $2 billion at a valuation above $50 billion.

The move makes strategic sense given where each company currently stands. Cursor currently pays retail prices to Anthropic and OpenAI to the same companies competing directly against it with Claude Code and Codex. That means every dollar of revenue Cursor earns partially funds its own competition. With SpaceX bringing computational infrastructure to the Cursor platform, that could reduce Cursor’s dependence on OpenAI and Anthropic’s Claude AI as its providers. Access to SpaceX’s Colossus supercomputer, with compute equivalent to one million Nvidia H100 chips, gives Cursor the infrastructure to run and train its own models at a scale it could never afford independently. That one change restructures the entire unit economics of the business.

Elon Musk teases crazy outlook for xAI against its competitors

Cursor’s $2 billion in annualized revenue and enterprise reach across more than half of Fortune 500 companies gives SpaceX something its xAI subsidiary currently lacks, which is a proven, fast-growing software business with real enterprise distribution.

For Cursor, SpaceX’s $10 billion in joint development funding is transformational. Cursor raised $3.3 billion across all of 2025 to reach that $2 billion in revenue. A single $10 billion commitment from SpaceX, even as a development payment rather than an acquisition, dwarfs everything Cursor has raised in its entire existence. That capital accelerates product development, enterprise sales infrastructure, and proprietary model training simultaneously.

The timing is deliberate. SpaceX filed confidentially with the SEC on April 1, 2026, targeting a June listing at a $1.75 trillion valuation, in what would be the largest public offering in history. The company is expected to begin its roadshow the week of June 8, with Bank of America, Goldman Sachs, JPMorgan, and Morgan Stanley serving as underwriters. Adding Cursor to the portfolio before that roadshow gives IPO investors a concrete enterprise software revenue story to price in, alongside rockets and satellite internet.

The deal also addresses a weakness that became visible after February’s xAI merger. Several xAI co-founders departed following that acquisition, and SpaceX had already hired two Cursor engineers, signaling where its AI talent strategy was heading. Cursor, for its part, faces a pricing disadvantage competing against Anthropic’s Claude Code.

Whether SpaceX exercises the full acquisition option before its IPO or after remains the open question. Either way, this deal reshapes what investors will be buying into when SpaceX goes public.

Tesla Supercharger for Business exposes jaw-dropping ROI gap between best and worst locations

Tesla’s new Supercharger for Business calculator reveals an eye-opening all-in cost and location-based ROI projections.

Published

tesla v4 supercharger

Tesla has launched an online calculator for its Supercharger for Business program, giving property owners their first transparent look at what it really costs to install Superchargers on site and what kind of return they can expect.

The program itself launched in September 2025, allowing businesses to purchase and operate Supercharger hardware on their own property while Tesla handles installation, maintenance, software, and 24/7 driver support. As Teslarati reported at launch, hosts also get their logo placed on the chargers and their location integrated into Tesla’s in-car navigation, meaning drivers are actively routed there. The stalls are open to all EVs, not just Teslas.


The new online calculator, announced by Tesla on Wednesday with the note that “simplicity and transparency” have been a problem in the industry, lets any business enter a U.S. address and get a real cost and revenue model. A standard 8-stall V4 Supercharger site runs approximately $500,000 in hardware and $55,000 per post for installation, bringing an all-in price just shy of $1 million. Tesla charges a flat $0.10 per kWh fee to cover software, billing, and network operations. Businesses set their own retail price and keep the margin above that fee.

Taking a look at Tesla’s Supercharger for Business online calculator, we can see that ROI is not uniform, and the gap between a strong location and a poor one can stretch the breakeven point by several years.

The biggest driver is foot traffic and how long people stay. A busy rest station, hotel, or outlet mall brings in repeat visitors who need to charge while they’re already stopped, pushing utilization numbers higher and shortening payback time.

Local electricity rates matter just as much on the cost side. Markets like California carry some of the highest commercial electricity rates in the country, which eats into the margin between what a host pays per kWh and what they charge drivers. At the same time, dense urban areas with high EV adoption tend to support higher retail charging prices, which can offset that cost if demand is strong enough. Weather also plays a role. Cold climates reduce battery efficiency and increase charging frequency, but they can also suppress utilization in winter months if drivers avoid stopping in exposed outdoor locations. Suburban and rural sites face a different problem: lower baseline EV traffic, which means a site with cheaper power and lower operating costs can still take longer to pay back simply because the stalls sit idle more often. Tesla’s calculator uses real fleet data to pre-fill utilization estimates by ZIP code, so businesses can run their specific address against these variables rather than relying on averages.

The program has seen real adoption. Wawa, already the largest host of Tesla Superchargers with over 2,100 stalls across 223 locations, opened its first fully owned and branded site in Alachua, Florida earlier this year. Francis Energy of Oklahoma and the city of Alpharetta, Georgia have also deployed branded stations through the program, as Teslarati covered in January.

Tesla now exceeds 80,000 Supercharger stalls worldwide, and the calculator makes the economic case for accelerating that number through private investment rather than company-owned sites alone.

Tesla’s newest “Folding V4 Superchargers” are key to its most aggressive expansion yet

Tesla’s folding V4 Supercharger ships 33% more per truck, cuts deployment time and cost significantly.

Tesla V4 Supercharger installation ramping in Europe

Tesla is rolling out a folding V4 Supercharger design, an engineering change that allows 33% more units to fit on a single delivery truck, cuts deployment time in half, and reduces overall installation cost by roughly 20%.

The folding mechanism addresses one of the least glamorous but most consequential bottlenecks in charging infrastructure: getting hardware from factory floor to job site efficiently. By collapsing the form factor for transit and unfolding into an operational configuration on arrival, the new design dramatically reduces the logistics overhead that has historically slowed Supercharger rollouts, particularly at large or remote sites where multiple units are needed simultaneously.

The timing aligns with a broader acceleration in Tesla’s network strategy. In March 2026, Tesla’s Gigafactory New York produced its final V3 Supercharger cabinet after more than seven years and 15,000 units, pivoting entirely to V4 cabinet production. The V4 cabinet itself is already a generational leap, delivering up to 500 kW per stall for passenger vehicles and up to 1.2 MW for the Tesla Semi, while supporting twice the stalls per cabinet at three times the power density of its predecessor. The folding transport innovation layers logistical efficiency on top of that technical foundation.

Tesla Charging’s Director Max de Zegher, commenting on the V4 cabinet when it launched, captured the operational philosophy behind these changes: “Posts can peak up to 500kW for cars, but we need less than 1MW across 8 posts to deliver maximum power to cars 99% of the time.” The design philosophy has always been about maximizing real-world throughput, not just peak specs, and the folding transport upgrade extends that thinking into the supply chain itself.
