Tesla Opens World’s Largest Supercharger in California With 164 Solar-Powered Stalls

The world’s largest Tesla Supercharger is now fully operational in Lost Hills, California, delivering 164 charging stalls powered almost entirely by the sun.

Tesla confirmed the completion of its “Oasis” Supercharger station via X, marking a major infrastructure milestone just in time for Thanksgiving travel on one of America’s busiest EV corridors.

The station operates virtually off-grid, drawing power from 11 megawatts of solar panels and 39 megawatt-hours of Megapack battery storage. For EV drivers traveling Interstate 5 between San Francisco and Los Angeles, this changes everything.

164 Stalls, 30 Acres, Zero Grid Dependence

The Lost Hills Supercharger dwarfs every other charging station in Tesla’s global network.

Spanning 30 acres of land, the facility features 164 V4 Supercharger stalls capable of delivering up to 325 kilowatts each. That is enough to add approximately 200 miles of range in just 15 minutes for compatible vehicles.

Tesla equipped the site with 12 pull-through stalls specifically designed for drivers towing trailers or boats. This addresses a critical pain point for Cybertruck and Model X owners who previously had to unhitch before charging.

The station relies on just 1.5 megawatts of grid connection as backup. Ten Tesla Megapacks store excess solar energy for nighttime and cloudy conditions, making the site essentially self-sufficient.

Off-Grid Charging Becomes Reality

Tesla has promised solar-powered Superchargers for nearly a decade. Lost Hills finally delivers on that vision.

CEO Elon Musk first floated the concept back in 2016, suggesting most Superchargers would eventually operate independently of utility companies. The pieces were always there: Tesla’s solar panels, Megapack batteries, and V4 charging hardware. Lost Hills proves they work together at scale.

The 11 MW solar array generates enough electricity to power approximately 2,000 homes annually. During peak sunlight hours, the station produces seven times more energy than its minimal grid connection could provide.

This matters beyond environmental bragging rights. When California’s grid fails during heat waves or wildfires, Lost Hills keeps charging. For EV owners, that is genuine energy independence.

Strategic Location on America’s Busiest EV Route

Lost Hills sits 142 miles northwest of Los Angeles along the I-5 corridor, the primary artery connecting Southern and Northern California.

This stretch of highway sees millions of vehicles annually. Before Lost Hills, EV drivers faced charging bottlenecks at smaller stations in Kettleman City and Coalinga. The 164-stall capacity can theoretically handle over 1,000 vehicles daily, assuming average charge times of 20 minutes.

Tesla opened the first 84 stalls on July 4, 2025, just before the holiday weekend rush. The remaining stalls came online in stages, with full operation confirmed this week.

The station operates 24/7 and is accessible to all electric vehicles through Tesla’s North American Charging Standard (NACS), which Ford, GM, Volkswagen, and Stellantis have all adopted.

Construction Speed Defies Industry Norms

Tesla broke ground on Lost Hills in October 2024 and completed the entire project in approximately 13 months.

That timeline would be remarkable for any infrastructure project, but it is particularly striking given the station’s complexity. Tesla had to coordinate solar installation, Megapack deployment, V4 charging hardware, and site construction simultaneously.

The company used pre-assembled Supercharger units with four stalls each, dramatically accelerating installation. Max de Zegher, Tesla’s Director of Charging for North America, documented the process on X, showing 30 pre-assembled units arriving in a single delivery.

By comparison, federally funded charging stations under the National Electric Vehicle Infrastructure (NEVI) program have faced years of delays and cost overruns. Tesla built the world’s largest Supercharger faster than many competitors can secure permits.

EVXL’s Take

Lost Hills represents Tesla executing on promises that seemed like marketing fantasy a decade ago.

When EVXL first covered this project in April 2025, the industry questioned whether Tesla could deliver 168 stalls powered primarily by solar. The final count landed at 164, but the core achievement stands: a massive, off-grid charging hub that actually works.

The timing carries significant irony. This station opened fully just months after the Trump administration passed legislation eliminating incentives for solar, energy storage, and electric vehicles. Tesla built the exact infrastructure that policy is trying to kill, and it did so faster and cheaper than government-funded alternatives.

As we reported when Tesla’s Oasis opened its first phase in July, the station’s 1.5 MW grid connection raised questions about reliability. Four months of operation have answered them. The solar and Megapack combination handles demand even during peak travel periods.

This matters because Tesla’s Supercharger network is no longer just for Tesla drivers. Eighteen non-Tesla brands now access the network through NACS adapters or native ports. Volkswagen joined just last week. Every driver passing through Lost Hills benefits from Tesla’s infrastructure investment.

The energy story here is arguably bigger than the charging story. Tesla deployed 39 MWh of Megapack storage at a single location, demonstrating the same technology driving record growth at the company’s energy division. While automotive margins compress and EV sales face post-tax-credit headwinds, energy storage is becoming Tesla’s most profitable business segment.

Lost Hills also validates Tesla’s decision to integrate Supercharger data with Google Maps. Drivers of any brand can now see real-time availability at this 164-stall station before arriving, reducing congestion and improving the charging experience for everyone.

Looking ahead, Tesla has already permitted a 168-stall station in nearby Coalinga and is planning a 200-stall site in Florida. If Lost Hills serves as the blueprint, these mega-stations could transform long-distance EV travel nationwide.

The bigger question is whether anyone else can replicate this model. Electrify America and ChargePoint lack Tesla’s vertical integration across vehicles, solar, and storage. They cannot build off-grid stations because they do not manufacture the batteries.

For now, Lost Hills stands alone: the world’s largest Supercharger, powered by the sun, open to all EVs, and built in just over a year. That is not marketing. That is execution.
