Tesla Powerwall, Powerpack batteries helps Nova Scotia weather power outages
Tesla’s residential Powerwall and commercial Powerpack battery storage units are becoming invaluable for residents in Elmsdale, Nova Scotia, Canada.
The batteries are a key part of the ongoing Intelligent Feeder Project, a partnership between the Nova Scotia power and Opus One Solutions through a grant from the Sustainable Development Technology in Canada. The program is a test to determine the viability of battery storage units as a potential backup for Nova Scotia’s energy grid, both in the micro and macro level.
For the micro level, ten Elmsdale homes that are part of a microgrid had Tesla Powerwall 2 units installed. At the macro level, Tesla Powerpacks were deployed at the Elmsdale substation are storing energy generated by wind turbines located at Hardwood Lands, NS. The commercial batteries are expected to be a good fit for the region’s grid, as 19% of Nova Scotia’s electricity is already being produced from wind turbines.
Nova Scotia Power project manager Jill Searle highlighted the potential of the initiative in a statement to Truro Daily. “We wanted to see if we could use batteries, not just in customers’ homes, but also to see if they could provide reliability with wind integration for a whole distribution circuit,” she said.
An opportunity for the Tesla batteries to prove their value emerged on January 4, 2019, when the region was faced with a 5-hour power outage during the height of a snowstorm. Apart from seeing uninterrupted power, several homeowners with the Powerwall 2 also observed that their batteries still had over 85% by the time power came back on. Elmsdale residents Mac and Anne Noble, whose home was fitted with a Tesla Powerwall 2 battery, shared their experiences during power outages.
“When the power goes out, it’s completely instantaneous. The (desktop) computer I have over there, it didn’t even flicker when it went out,” Mac Noble said.
For the senior program manager, Tesla’s batteries are showing signs that they can perform very well. “This project, for us and for me personally, has been fantastic. We’ve had a lot of industry interest in this because a lot of jurisdictions are talking about storage as a utility asset, but not many are actually doing it. We’re one of the few who are. We are leading edge on some of this work, which is really exciting,” she said.
The pilot program for the Intelligent Feeder Project is scheduled to run until the end of 2019. The Powerwalls and Powerpacks used in the program are expected to remain deployed even after the pilot program ends.
Tesla’s Energy business is growing at a rapid rate, with the company deploying 1.04 GWh of energy storage over 2018. Production of Powerwall and Powerpack modules at Gigafactory 1 are also getting expedited thanks to a new manufacturing line from Tesla Grohmann. Tesla ultimately aims to more than double its energy storage deployments to over 2 GWh in 2019.

Tesla named by U.S. Gov. in $4.3B battery deal for American-made cells
What began as an open secret in the energy industry was confirmed by the U.S. Department of the Interior on Monday: Tesla is the buyer behind LG Energy Solution’s blockbuster $4.3 billion battery supply agreement.
What began as an open secret in the energy industry is becoming more real after the U.S. Department of the Interior named Tesla as the stakeholder in the LG Energy Solution’s blockbuster $4.3 billion battery supply agreement.
Tesla and LG Energy Solution are expanding their partnership to build a LFP prismatic battery cell manufacturing facility in Lansing, Michigan, launching production in 2027. The announcement, made as part of the Indo-Pacific Energy Security Summit results, ends months of speculation.
“American-made cells will power Tesla’s Megapack 3 energy storage systems produced in Houston, creating a robust domestic battery supply chain.”, notes a press release on the U.S. Department of the Interior website.
Tesla has long utilized China’s Contemporary Amperex Technology Co. (CATL), the world’s largest LFP battery maker, as one of its primary suppliers. That relationship made financial sense for years, considering that Chinese LFP cells were cheap, abundant, and reliable. But with escalated tariffs on Chinese imports and an increasingly growing Tesla Energy business that’s particularly reliant on LFP cells for products including its Megapack battery storage units designed for utilities and large-scale commercial projects.
The announcement of a deepened partnership between LG Energy Solution and Tesla has strategic logic for both parties. For Tesla, it secures a tariff-compliant, domestically produced battery supply for its fast-growing energy division. LGES, now producing LFP batteries in Michigan, becomes the only major supplier currently scaling U.S. production, outpacing rivals like Samsung SDI and SK On. LG Energy Solution’s Lansing plant, formerly known as Ultium Cells 3, was previously operated as a joint venture with General Motors. LGES acquired GM’s stake in May 2025 and now fully owns the site, with a production capacity of 50 GWh per year. LG Energy said the contract includes options to extend the supply period by up to seven years and boost volumes based on further consultations.
For the broader industry, the ripple effects are significant. This deal signals that domestic battery manufacturing can be financially viable and not just aspirational. Utilities, energy developers, and rival automakers will take note as American-made LFP supply becomes a competitive reality rather than a distant promise.
For consumers, the benefits will take time but are real. A more resilient, U.S.-based supply chain means fewer price shocks from trade disputes, more stable Megapack availability for the grid storage projects that reduce electricity costs, and long-term downward pressure on energy storage prices as domestic production scales.
Deliveries are set to begin in 2027 and run through mid-2030, and as grid storage demand accelerates, reliable, US-made battery supply is no longer a future ambition. It is becoming a core requirement of the country’s energy strategy.

Tesla Energy gains UK license to sell electricity to homes and businesses
The license was granted to Tesla Energy Ventures Ltd. by UK energy regulator Ofgem after a seven-month review process.
Tesla Energy has received a license to supply electricity in the United Kingdom, opening the door for the company to serve homes and businesses in the country.
The license was granted to Tesla Energy Ventures Ltd. by UK energy regulator Ofgem after a seven-month review process.
According to Ofgem, the license took effect at 6 p.m. local time on Wednesday and applies to Great Britain.
The approval allows Tesla’s energy business to sell electricity directly to customers in the region, as noted in a Bloomberg News report.
Tesla has already expanded similar services in the United States. In Texas, the company offers electricity plans that allow Tesla owners to charge their vehicles at a lower cost while also feeding excess electricity back into the grid.
Tesla already has a sizable presence in the UK market. According to price comparison website U-switch, there are more than 250,000 Tesla electric vehicles in the country and thousands of Tesla home energy storage systems.
Ofgem also noted that Tesla Motors Ltd., a separate entity incorporated in England and Wales, received an electricity generation license in June 2020.
The new UK license arrives as Tesla continues expanding its global energy business.
Last year, Tesla Energy retained the top position in the global battery energy storage system (BESS) integrator market for the second consecutive year. According to Wood Mackenzie’s latest rankings, Tesla held about 15% of global market share in 2024.
The company also maintained a dominant position in North America, where it captured roughly 39% market share in the region.
At the same time, competition in the energy storage sector is increasing. Chinese companies such as Sungrow have been expanding their presence globally, particularly in Europe.
