It appears that Tesla’s energy business is hitting its stride. In a recent blog post, Tesla Japan shared some insights about its virtual power plant (VPP) in Miyakojima, located in Okinawa Prefecture, Japan. The electric vehicle maker included a video that features some key insights from homeowners who are part of the VPP program.
Started in 2021, the Miyakojima virtual power plant has exceeded 300 homes. As noted by Tesla, the system is the first commercial use of Powerwall home batteries for a virtual power plant in Japan. It would also be one of the country’s largest commercial VPPs using household storage batteries when it is fully completed.
Similar to other VPPs that Tesla has set up, the Powerwall batteries installed in the Miyakojima VPP could provide backup power to the grid when needed. In Miyako Island, for example, the Powerwall batteries help the island stabilize its power. The home batteries also enable residents to have energy in times when power is unavailable, such as when typhoons hit.
Tesla’s video of the Miyakojima virtual power plant showcased several Powerwall owners, some of whom highlighted that the area attracts a substantial number of tourists every year. With this in mind, having an uninterrupted power supply even when grid power goes down is invaluable. “During typhoons, lights are available, refrigerators are usable as usual. What could be better than that?” one Powerwall owner said.
Other Powerwall owners noted that the idea of sharing stored energy with each other as a community is something that is quite noble. Apart from this, the use of home battery units like Powerwalls helps keep the environment safe. With the accelerating use of renewables, some Powerwall users in the area are optimistic that the nature around the island, including the oceans, could be restored.
Tesla Energy is a sleeping giant. Elon Musk said as much in the past when he noted that Tesla Energy could very well be larger than the company’s automotive business. While Tesla Energy still tends to take a backseat to the company’s EV division, it is making a lot of headway. Just recently, for example, about 2,600 homeowners in Tesla’s California VPP helped the state’s grid by providing up to 18 MW of power.

Tesla Megapacks chosen for 548 MWh energy storage project in Japan
Tesla plans to supply over 100 Megapack units to support a large stationary storage project in Japan, making it one of the country’s largest energy storage facilities.

Tesla’s Megapack grid-scale batteries have been selected to back an energy storage project in Japan, coming as the latest of the company’s continued deployment of the hardware.
As detailed in a report from Nikkei this week, Tesla plans to supply 142 Megapack units to support a 548 MWh storage project in Japan, set to become one of the country’s largest energy storage facilities. The project is being overseen by financial firm Orix, and it will be located at a facility Maibara in central Japan’s Shiga prefecture, and it aims to come online in early 2027.
The deal is just the latest of several Megapack deployments over the past few years, as the company continues to ramp production of the units. Tesla currently produces the Megapack at a facility in Lathrop, California, though the company also recently completed construction on its second so-called “Megafactory” in Shanghai China and is expected to begin production in the coming weeks.

Tesla’s production of the Megapack has been ramping up at the Lathrop facility since initially opening in 2022, and both this site and the Shanghai Megafactory are aiming to eventually reach a volume production of 10,000 Megapack units per year. The company surpassed its 10,000th Megapack unit produced at Lathrop in November.
During Tesla’s Q4 earnings call last week, CEO Elon Musk also said that the company is looking to construct a third Megafactory, though he did not disclose where.
Last year, Tesla Energy also had record deployments of its Megapack and Powerwall home batteries with a total of 31.4 GWh of energy products deployed for a 114-percent increase from 2023.
Other recently deployed or announced Megapack projects include a massive 600 MW/1,600 MWh facility in Melbourne, a 75 MW/300 MWh energy storage site in Belgium, and a 228 MW/912 MWh storage project in Chile, along with many others still.

Elon Musk responds to Ontario canceling $100M Starlink deal amid tariff drama
Ontario Premier Doug Ford said, opens new tab on February 3 that he was “ripping up” his province’s CA$100 million agreement with Starlink in response to the U.S. imposing tariffs on Canadian goods.

Elon Musk company SpaceX is set to lose a $100 million deal with the Canadian province of Ontario following a response to the Trump administration’s decision to apply 25 percent tariffs to the country.
Starlink, a satellite-based internet service launched by the Musk entity SpaceX, will lose a $100 million deal it had with Ontario, Premier Doug Ford announced today.
Starting today and until U.S. tariffs are removed, Ontario is banning American companies from provincial contracts.
Every year, the Ontario government and its agencies spend $30 billion on procurement, alongside our $200 billion plan to build Ontario. U.S.-based businesses will…
— Doug Ford (@fordnation) February 3, 2025
Ford said on X today that Ontario is banning American companies from provincial contracts:
“We’ll be ripping up the province’s contract with Starlink. Ontario won’t do business with people hellbent on destroying our economy. Canada didn’t start this fight with the U.S., but you better believe we’re ready to win it.”
It is a blow to the citizens of the province more than anything, as the Starlink internet constellation has provided people in rural areas across the globe stable and reliable access for several years.
Musk responded in simple terms, stating, “Oh well.”
Oh well https://t.co/1jpMu55T6s
— Elon Musk (@elonmusk) February 3, 2025
It seems Musk is less than enthused about the fact that Starlink is being eliminated from the province, but it does not seem like all that big of a blow either.
As previously mentioned, this impacts citizens more than Starlink itself, which has established itself as a main player in reliable internet access. Starlink has signed several contracts with various airlines and maritime companies.
It is also expanding to new territories across the globe on an almost daily basis.
With Mexico already working to avoid the tariff situation with the United States, it will be interesting to see if Canada does the same.
The two have shared a pleasant relationship, but President Trump is putting his foot down in terms of what comes across the border, which could impact Americans in the short term.
