The U.S. Department of Energy estimates that its planned output could support batteries for up to 800,000 electric vehicles a year, but that is a projected annual equivalent, not a count of cars already powered or a lifetime total. Nevada issued key state permits on February 25, 2022; the developer’s February 2026 schedule targeted start-up in late 2027, followed by a ramp-up through 2028.
What is Thacker Pass, and what has been approved?
Thacker Pass is an open-pit mine and lithium-processing project in Humboldt County, within the McDermitt Caldera. Nevada issued the project air, water and mining permits on February 25, 2022. Those permits are an approval milestone; they do not mean the mine is producing lithium. As of Lithium Americas’ February 2026 update, Phase 1 construction was underway.
The project’s planned process starts with mining and crushing ore, followed by acid leaching and processing to make lithium carbonate. The Nevada Division of Environmental Protection (NDEP) says the design includes an acid plant that will supply sulfuric acid for leaching and generate steam to power the mine. The expected product cited by the U.S. Department of Energy (DOE) is battery-grade lithium carbonate.
How much lithium and how many EV batteries could it support?
DOE lists expected production of approximately 40,000 tonnes of battery-grade lithium carbonate per year. It says that output could support batteries for up to 800,000 electric vehicles annually. That figure is an agency projection of potential battery capacity, not a measure of cars already on the road or the mine’s cumulative lifetime production. DOE also estimates the output could correspond to avoiding 317 million gallons of gasoline consumption per year; that is an agency comparison, not a measured reduction.

- Energizer Double A Lithium batteries are the world's longest lasting AA batteries.
- These AA Energizer batteries power your most critical devices, great for smart home devices, outdoor surveillance systems, digital cameras, Blink outdoor cameras, and handheld games
- An Ultimate Lithium battery can hold power up to 25 years in storage for trustworthy backup energy, so you are always prepared
- Energizer lithium AA batteries are made with leak-proof construction to help protect devices (based on standard use)
- AA lithium batteries can perform in extreme temperatures from -40F to 140°F for year-round, indoor and outdoor use
The scale figures describe different things: lithium output is a projected production rate, while vehicle and gasoline figures translate that planned output into possible annual equivalents. Actual production and its effects depend on the project being completed, operating, and reaching the assumptions behind those projections.
How is the mine regulated?
Nevada’s permits set requirements for air emissions, water pollution control and site reclamation. NDEP says mining below the water table is prohibited. The water pollution control permit must be renewed every five years; the air permit establishes emission limits and requires regular monitoring, records and reporting. The reclamation permit requires financial assurance of more than $47 million for restoration, according to NDEP’s project information.

- 8 pack of Energizer Ultimate Lithium AA Batteries
- Energizer Ultimate Lithium AA batteries are the world's longest lasting AA batteries
- Performs in extreme temperatures from -40 degrees F to 140 degrees F to ensure reliable use in all seasons
- These double A batteries are leak proof batteries, guaranteed based on standard use
- Lightweight household batteries last up to 25 years in storage
NDEP says the permitted controls can protect public health and the environment. That is the agency’s permitting conclusion; it does not mean environmental effects are absent. Permit conditions and monitoring requirements govern the project’s obligations as it is built and operated.
What are the project’s financing and job estimates?
In October 2024, DOE announced a $2.26 billion loan for the project, consisting of $1.97 billion in principal and $289.7 million in capitalized interest. At loan closing, DOE estimated approximately 1,800 construction jobs and 360 operating jobs. These are agency estimates, not a guarantee of realized employment.

CEO Jonathan Evans described the progress in the company release as: “2025 was a pivotal year for Lithium Americas and the Thacker Pass Project with Phase 1 construction well underway,” (Lithium Americas, February 19, 2026). That is the developer’s characterization of progress, rather than an independent assessment.
What the headline’s “millions of electric cars” leaves out
The project’s publicized vehicle figure is up to 800,000 EV batteries per year, based on DOE’s estimate—not “untold millions” of vehicles. Because it is an annual projection, it should not be multiplied across future years as though production were assured or constant. The project was still under construction in the company’s February 2026 update, and the schedule and output remain prospective.
For a personal-finance reader, the useful distinction is between a large industrial project’s potential economic scale and an outcome already delivered. The announced federal loan, jobs estimates and projected production describe financing and expectations; they do not establish final costs, realized employment, actual lithium output or the project’s eventual financial returns.
