Tesla Energy, battery storage broke new ground in 2018, and 2019 will be even better
Visionaries like Elon Musk, who are aiming for a world powered by sustainable energy, would be proud of the industry’s progress in 2018. Over the course of the year, investments flowed into research, the prices of batteries declined, governments across the globe supported clean energy solutions, and electric vehicles such as the Tesla Model 3 led the charge in transitioning the transportation sector away from fossil fuels.
A study from Bloomberg New Energy Finance has noted that in 2018, global annual energy storage more than doubled, reaching 9 GWh, and it is currently on pace to rise another 78% this year. In August 2018, the cumulative sales of electric cars passed the 4 million mark as well, and NEF analysts expect the EV industry to surpass 5 million in sales in the first quarter of 2019. Even in the United States, where companies like Tesla are struggling to meet the demand for their residential energy products, deployments on a rated-power basis across the country rose 57% to an estimated 338 KW after three years of flat to negative growth.
At the core of all this growth are the advancements in battery technology. Producers of batteries have ramped their operations to meet increasing demand, from China’s BYD Co. Ltd. to South Korea’s LG Chem to Japan’s Panasonic Corp. and its US partner Tesla. Benchmark Mineral Intelligence notes that by 2028, the combined manufacturing capacity of these battery producers would likely reach at least 1,330 GWh. That’s about ten times greater than the entire’s industry’s total capacity entering 2018.
In an email to S&P Global Market Intelligence, Simon Moores, managing director of Benchmark Mineral Intelligence, mentioned that the scale of recent battery projects signifies a change in the market. Moores also pointed out that while the emergence of electric cars is notable, the rise of energy storage has been impressive as well.
“When you see projects now being planned at over 1 GWh in scale, when only 18 months ago a 300-MWh installation was something to behold, you know you have entered a new era. It has been quite interesting to watch the battery makers’ dilemma of where to send the lithium-ion cells. Of course, they have contracts to honor with automotive producers, but the order inquiries from [energy storage] producers have been incredible,” Moores said.
One thing that is working in favor of renewables today is the falling prices of batteries and clean energy as a whole. Tom Buttgenbach, president and CEO of developer 8minutenergy Renewables LLC, described this in a statement to S&P Global Market Intelligence.
“I can beat a gas peaker anywhere in the country today with a solar-plus-storage power plant. Who in their right mind today would build a new gas peaker? We are a factor of two cheaper,” he said.
Buttgenbach’s statements echo the words of Tesla Chief Technology Officer JB Straubel, who noted last year that the age of fossil fuel powered peaker plants is at an end. Speaking to the San Francisco Chronicle, Straubel stated that batteries, even at their current state, are already starting to prove themselves as superior to conventional energy solutions.
“I think what we’ll see is we won’t build many new peaker plants, if any. Already what we’re seeing happening is the number of new ones being commissioned is drastically lower, and batteries are already outcompeting natural gas peaker plants,” the Tesla CTO said.
While the progress of batteries has been impressive, though, Logan Goldie-Scot, head of energy storage at Bloomberg NEF, has stated that the past year exhibited uneven growth among different regions across the globe. South Korea, for one, saw a rise in energy deployments, while territories like the United Kingdom took a step back. In the United States, extreme demand such as those faced by Tesla Energy for products like the Powerwall 2 also caused delays in installations. Yet, despite these, Goldie-Scot stated that 2018 was a turning point for energy storage nonetheless.
“Even though progress was uneven, there was a much greater consensus in 2018 over the importance of energy storage, even in the near term, in major markets. In 2017, there were still a lot of people talking about how energy storage was not necessarily a competitive solution and was going to be limited. I hear those conversations much less now. Energy storage is now becoming more integrated into resource plans,” she said.
Amidst this transition, companies such as Tesla are taking the battle to heart. Last November, for example, Tesla opened the doors of Gigafactory 2 in Buffalo, NY to select members of the media. During the media visit, Tesla noted that it is aiming to ramp operations in the site with more hires, and that the 1.2-million sq ft facility is already running 24/7, with employees alternating 12-hour shifts. Tesla’s Gigafactory 2 is expected to play a huge role in the company’s energy business, considering that it is the site where the Solar Roof tiles, the company’s flagship solar product, are being manufactured.
In a notable intersection of Big Tech powerhouses, Meta, led by Mark Zuckerberg, has partnered with Canadian energy infrastructure giant Enbridge on a significant renewable energy initiative that will rely on battery technology from Elon Musk’s Tesla.
The project, which was announced this week, marks another step in Meta’s aggressive push to power its expanding data center operations with clean energy, dispelling many of the complaints people have about them.
This new development is located near Cheyenne, Wyoming, and will feature a 365-megawatt (MW) solar farm paired with a 200 MW/1,600 megawatt-hour (MWh) battery energy storage system, also known as BESS. Tesla is providing the batteries for the project, valued at roughly $200 million.
The story was originally reported by Utility Dive.
This Wyoming project represents the first phase of Enbridge and Meta’s joint “Cowboy Project.” Once operational, it will deliver power to Meta’s regional data centers through Cheyenne Light, Fuel, and Power under Wyoming’s Large Power Contract Service tariff.
This tariff, originally developed in collaboration with Microsoft and Black Hills Energy, is designed specifically for large loads like data centers. It ensures that the renewable supply serves hyperscale customers without impacting retail electricity rates for other users.
The battery system will operate under a long-term tolling agreement, providing dispatchable capacity that enhances grid reliability. During periods of high demand, the utility can access the backup generation, addressing one of the key challenges of integrating large-scale renewables with the explosive growth of data center electricity demand driven by artificial intelligence.
This latest collaboration builds on prior joint efforts between Enbridge and Meta in Texas, including the 600 MW Clear Fork Solar, 152 MW Easter Wind, and 300 MW Cone Wind projects. Together with the Wyoming initiative, the companies have now partnered on roughly 1.6 gigawatts (GW) of combined solar, wind, and storage capacity.
The deal highlights the intensifying demand for reliable, low-carbon power from technology giants. Meta has committed to supporting its data center growth with renewable energy, joining peers like Microsoft and Google in seeking large-scale solutions. Enbridge’s Allen Capps described the project as “one of the larger utility-scale battery installations supporting U.S. data center operations and growth.”
The involvement of Tesla’s battery technology adds an intriguing layer, linking two of the world’s most prominent tech leaders—Zuckerberg and Musk—in the clean energy transition.
As data centers continue to drive unprecedented electricity load growth across the United States, projects like this one illustrate how hyperscalers are turning to strategic partnerships with traditional energy players and innovative storage solutions to meet both sustainability goals and reliability needs.

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.
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.
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.
We launched Supercharger for Business in 2025 to help companies get charging right. We found simplicity and transparency to be a problem in this industry.
We’re now sharing pricing and a financial calculator to help make informed decisions. The goal is to accelerate investments,…

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.
