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.

Installation of the standard system carries no additional charge. The package features Storm Watch for outage protection and allows complete management through a single Tesla application. The system supplies continuous whole-home backup capability.
The Powerwall system enables households to maintain electricity during severe storms that disrupt the utility grid. When outages occur, the batteries automatically provide seamless backup power to the home.
Tesla announces 100k Powerwalls are participating in Virtual Power Plants
Tesla Storm Watch monitors weather forecasts and ensures the units are fully charged ahead of anticipated severe weather events so that power remains available throughout the disruption, keeping lights, refrigeration, and other essential systems operating without interruption.
Availability is restricted to select Texas locations where retail electric choice exists. Participants must lease exactly two Powerwall units and maintain continuous enrollment with Tesla Electric. Solar panels cannot be included under this particular lease arrangement.
The monthly credit activates automatically once the system is installed, receives permission to operate, and enrollment is confirmed. To retain the credit, customers are required to stay enrolled in Tesla Electric and fulfill all program conditions.
Nonstandard installations that involve electrical upgrades or special permitting may lead to extra expenses and might impact eligibility for the credit, so be sure to check with either your installer or Tesla to ensure you will still qualify.

Inside Tesla’s secretive $10 Billion “Project Crystal Sun” filing
Tesla filed for a $10.1 billion Fort Bend solar factory, but the site isn’t confirmed.
Tesla has filed paperwork in Texas for a second massive manufacturing project in the same week it locked down its chip fabrication site, this time for a $10.1 billion solar cell plant in Fort Bend County. The filing, submitted July 22 under the state’s Jobs, Energy, Technology and Innovation Act and first surfaced by Sawyer Merritt on X, lists an internal project name of “Project Crystal Sun” and targets a site off FM 762 and FM 1994 near Richmond, about 40 minutes outside Houston.
Tesla is planning to build a $10.1 billion vertically integrated solar cell manufacturing facility in Fort Bend County, Texas, about 40 minutes from Houston, according to a new public application filing.

The application, prepared by Kroll Tax Services on Tesla’s behalf, spans five parcels totaling roughly 3,000 acres within the Lamar Consolidated Independent School District. Tesla wants a 10 year property tax limitation in exchange for the investment, split as $1.5 billion in real property and $8.6 billion in equipment and personal property. The company projects 9,712 permanent jobs once the plant reaches full operation, with 1,147 peak construction jobs during a build window running from this year through 2028 and commercial operations targeted for the first quarter of 2029.
Tesla is not fully committed to Fort Bend County yet. The filing states the company is weighing the site against an unnamed out of state alternative, and frames the tax abatement as what would make Texas competitive against that option. If the district and county decline the incentive, Tesla says it may build elsewhere.
Tesla Megapack Megafactory in Texas advances with major property sale

The plant would handle the full solar cell production chain in one facility, according to the filing, covering wafer and ingot manufacturing, coating, metallization and printing lines, cell testing, automated material handling and cleanroom infrastructure. That scope points to Tesla vertically integrating a part of its supply chain it currently sources largely from overseas partners, mirroring the approach behind its expanding Megapack production in Brookshire, Texas, where Tesla has already built out two buildings for its grid battery business.
The timing lines up closely with Tesla and SpaceX’s other big Texas commitment this month. SpaceX confirmed its Terafab chip factory would land in Grimes County days before this filing surfaced, with construction on that $16.8 billion project starting almost immediately after local officials met with residents. Terafab is meant to produce the AI chips running Tesla’s Optimus robots and Full Self-Driving software, while a solar cell plant would feed a different part of the business, the panels and storage systems Tesla sells to homeowners, businesses and utilities, and increasingly needs to power its own data centers.
Musk has talked about building domestic solar manufacturing capacity before, tying it to the amount of power Tesla’s AI ambitions will require.
Tesla just trademarked ‘MEGAPOD’ with the United States Patent and Trademark Office (USPTO), its latest move in what seems to be a hint that the company is incredibly focused on its AI efforts and storage needs as compute increases.
The application carries serial number 99893717 and lists the applicant as Tesla, Inc., located at 1 Tesla Road, Austin, Texas 78725.
The filing remains in ‘live pending’ status, and it is a new application waiting for assignment to an examining attorney. It has not yet been published or registered.

According to the official goods and services description in the application, Tesla describes ‘MEGAPOD’ as:
-
“Modular data center hardware systems for artificial intelligence computing, comprised of computer servers, computer hardware for artificial intelligence processing, computer networking hardware, electrical power distribution units, and cooling systems, sold as a unit; self-contained modular computing hardware systems for artificial intelligence workloads; integrated computer hardware platforms for artificial intelligence computing, namely, enclosures containing computer hardware, power distribution hardware, and cooling hardware, sold as a unit; downloadable software for monitoring, managing, optimizing, and regulating modular artificial intelligence computing hardware systems.”
This description specifies complete, self-contained modular units that integrate servers and specialized AI processing hardware with networking components, power distribution, and cooling systems. It also includes associated downloadable software for oversight and optimization of these systems. The language emphasizes hardware sold “as a unit” and enclosures that combine the necessary elements for AI computing workloads.
Tesla has an established history of developing and commercializing modular hardware systems. Its Megapack product line, for example, consists of utility-scale battery energy storage systems designed as containerized units for grid applications. The MEGAPOD filing follows a similar pattern of protecting a name for modular, integrated hardware platforms, this time focused on artificial intelligence computing infrastructure.
This could be an early move, especially as Tesla did not have trademark rights to the word ‘Cybercab,’ the name of its self-driving, ride-hailing-focused vehicle.
Trademark applications of this type allow companies to secure priority rights to a name for defined categories of goods and services. The USPTO examines applications for compliance with legal requirements, including distinctiveness and absence of conflicts with prior marks. If the application proceeds successfully through examination, publication, and any opposition period, it could result in a federal trademark registration providing nationwide protection. This is what Tesla’s obvious intention is with ‘MEGAPOD.’
Public reports and analysis suggest MEGAPOD could represent modular, container-style AI computing pods designed for easy deployment. These would bundle servers, AI accelerators, power systems, and cooling into self-contained units suitable for distributed AI workloads. This approach aligns with Tesla’s announced AI compute strategy.
In March 2026, Elon Musk outlined plans for “Digital Optimus” (also referred to as Macrohard), a joint Tesla-xAI project for AI agents capable of handling complex digital tasks. The plans include running these agents on Tesla’s AI4 hardware in parked vehicles as well as dedicated compute units installed at Supercharger stations, which collectively offer substantial unused electrical capacity.

A modular hardware platform like the one described in the ‘MEGAPOD’ filing would support scalable, rapid deployment of such distributed compute resources. It could complement Tesla’s other AI infrastructure efforts, including the Dojo supercomputer used for training models and the development of AI systems for autonomous driving and robotics, by enabling edge or regional AI inference without reliance on traditional centralized data centers.
