North Carolina creates state’s first microgrid laboratory, using Tesla Powerpacks
On a bitterly cold day in March 2015, power was interrupted from mainland Hatteras, North Carolina to an offshore island, Ocracoke. The reason? “Galloping lines,” or ice on the power lines that shorts out electricity delivery. Tideland Electric Membership Corporation, which supplies the island’s electricity, resorted to the only alternative: it fired up the island’s 3-megawatt generator, but electric demand exceeded the generator’s capacity numerous times that day. If you live on the Ocracoke, this was just one more instance of having to do without electrical power due to extreme weather.
But that’s all about to change.
With the installation of Tesla batteries and solar panels at the island’s generator, Ocracoke will become the state’s first microgrid laboratory. Tesla shipped ten of the 4,000-lb. Tesla Powerpack batteries combined to North Carolina Electric Membership Corporation’s (NCEMC) generating plant on Odd Fellows Lane. Tideland installed the 1 MWh photovoltaic system on December 13. “We’re setting up here for the electricity of the future,” said NCEMC’s Bob Beadle, project manager, as he participated in the installation.
The initiative is a pilot project from NCEMC, which owns the island’s generator, and Tideland. “This is a learning laboratory for Tideland,” said Heidi Jernigan Smith, Tideland spokesperson. “We’re exploring the potential for a microgrid.” She added that Ocracoke’s challenging coastal environment offered an ideal experiment site.
When connected to the grid, the batteries are charged during periods of low demand and store energy. The electricity is available to the grid when demand peaks and power is more expensive. While the batteries do not have the capacity to power Ocracoke during an outage, they will be able to assist the generator. “The Tesla batteries could potentially help us get over that start-up load,” Smith said. “It will be interesting to learn what benefits can be derived from the various microgrid components over time.”
The project will help all constituents to gain knowledge about how community microgrids can become another mechanism for regional electric service. “This is new territory for everyone,” Smith admitted. “We’re gaining valuable information for the future.”
The U. S. Department of Energy defines a microgrid as “a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid and that connects and disconnects from such grid to enable it to operate in both grid-connected or island mode.” Microgrids are an emerging segment of an electrical system infrastructure that helps isolated or remote areas become independent of large, centrally controlled power plants. As they draw upon efficient, renewable energy resources, microgrids in places like Ocracoke can provide data about the role of new technologies in future electric service delivery.
Another Tesla island project earlier this year on the American Samoa island of T’au, at 1.4 megawatts, can cover “nearly 100%” of its 600 residents’ electrical needs.
“Tideland is pleased to serve as host for NCEMC’s first microgrid project and the opportunity it affords our employees to learn about next generation energy technologies,” said Paul Spruill, Tideland’s chief executive officer and general manager. “We are also appreciative of our sister co-ops across the state for funding this project, which will all stand to gain from our collective knowledge base as the energy industry evolves.” The next time that the power is interrupted, Ocracoke may be able to manage its limited power resources as an independent system.
Smart technology is interwoven into Ocracoke’s microgrid in another way, too. 130+ Ocracoke homes have installed Ecobee thermostats from Tideland. Another example of the Internet of Things (IoT), these devices allow Tideland remote access to residents’ thermostat settings. Tideland can reduce energy usage during times of peak electricity. Homeowners can also use smart phones or other computers to monitor and control their thermostat settings, with expected saving of up to 23% on a monthly utility bill.

Tesla inks multi-billion-dollar deal with LG Energy Solution to avoid tariff pressure
Tesla has reportedly secured a sizable partnership with LGES for LFP cells, and there’s an extra positive out of it.
Tesla has reportedly inked a multi-billion-dollar deal with LG Energy Solution in an effort to avoid tariff pressure and domesticate more of its supply chain.
Reuters is reporting that Tesla and LGES, a South Korean battery supplier of the automaker, signed a $4.3 billion deal for energy storage system batteries. The cells are going to be manufactured by LGES at its U.S. factory located in Michigan, the report indicates. The batteries will be the lithium iron phosphate, or LFP, chemistry.
Tesla delivers 384,000 vehicles in Q2 2025, deploys 9.6 GWh in energy storage
It is a move Tesla is making to avoid buying cells and parts from overseas as the Trump White House continues to use tariffs to prioritize domestic manufacturing.
LGES announced earlier today that it had signed a $4.3 billion contract to supply LFP cells over three years to a company, but it did not identify the customer, nor did the company state whether the batteries would be used in automotive or energy storage applications.
The deal is advantageous for both companies. Tesla is going to alleviate its reliance on battery cells that are built out of the country, so it’s going to be able to take some financial pressure off itself.
For LGES, the company has reported that it has experienced slowed demand for its cells in terms of automotive applications. It planned to offset this demand lag with more projects involving the cells in energy storage projects. This has been helped by the need for these systems at data centers used for AI.
During the Q1 Earnings Call, Tesla CFO Vaibhav Taneja confirmed that the company’s energy division had been impacted by the need to source cells from China-based suppliers. He went on to say that the company would work on “securing additional supply chain from non-China-based suppliers.”
It seems as if Tesla has managed to secure some of this needed domestic supply chain.

Tesla Shanghai Megafactory produces 1,000th Megapack for export to Europe
The Shanghai Megafactory was able to hit this milestone less than six months after it started producing the Megapack.
Tesla Energy has announced a fresh milestone for its newest Megapack factory. As per the electric vehicle maker, the Shanghai Megafactory has successfully produced its 1,000th Megapack battery.
The facility was able to hit this milestone less than six months after it started producing the grid-scale battery system.
New Tesla Megapack Milestone
As per Tesla Asia in a post on its official accounts on social media platform X, the 1,000th Megapack unit that was produced at the Shanghai Megafactory would be exported to Europe. As noted in a CNEV Post report, Tesla’s energy products are currently deployed in over 65 countries and regions globally. This allows Tesla Energy to compete in energy markets that are both emerging and mature.
To commemorate the 1,000th Megapack produced at the Shanghai Megafactory, the Tesla China team posted with the grid-scale battery with celebratory balloons that spelled “Megapack 1000.” The milestone was celebrated by Tesla enthusiasts on social media, especially since the Shanghai Megafactory only started its operations earlier this year.
Quick Megafactory Ramp
The Shanghai Megafactory, similar to Tesla’s other key facilities in China, was constructed quickly. The facility started its construction on May 23, 2024, and it was hailed as Tesla’s first entry storage project outside the United States. Less than a year later, on February 11, 2025, the Shanghai Megafactory officially started producing Megapack batteries. And by March 21, 2025, Tesla China noted that it had shipped the first batch of Megapack batteries from the Shanghai plant to foreign markets.
While the Shanghai Megafactory is still not at the same level of output as Tesla’s Lathrop Megafactory, which produces about 10,000 Megapacks per year, its ramp seems to be quite steady and quick. It would then not be surprising if Tesla China announces the Shanghai Megafactory’s 2,000th Megapack milestone in the coming months.
