Tesla Is Planning the World's Largest Supercharger Station — 400 V4 Stalls

March 7, 2026 · Infrastructure

Tesla's Supercharger network just made two headlines in the same hour. First, a new 12-stall V3 station quietly opened in Abbotsford, BC — a welcome addition for Canadian owners in the Fraser Valley. Then came the bigger story: Tesla is planning a Supercharger station so large it will dwarf anything currently in existence. We're talking 400 individual V4 charging stalls, built in six phases, with construction on Phase 1 starting this year.

Let's break down both announcements and what they mean for the network as a whole.

🇨🇦 New Station: Abbotsford, BC — Delair Road

Tesla Charging's official account confirmed the opening of a 12-stall V3 Supercharger at Delair Road in Abbotsford, British Columbia. V3 Superchargers deliver up to 250 kW of peak charging power, capable of adding roughly 200 miles of range in 15 minutes on compatible vehicles.

For owners in the Greater Vancouver area and those traveling the Trans-Canada corridor, this station fills a meaningful gap. Abbotsford sits at a key junction between Vancouver and the BC Interior — a route that sees heavy Tesla traffic, particularly during ski season and summer travel.

⚡ The Big One: 400 V4 Stalls — World's Largest Supercharger

This is the announcement that changes the conversation. Sawyer Merritt, one of the most reliable Tesla infrastructure trackers, broke the news that Tesla is planning a Supercharger station with 400 individual V4 charging stalls. To put that in perspective: Tesla's current largest stations typically top out around 40–56 stalls. A 400-stall facility is an order of magnitude larger.

The project will be built in six phases, with Phase 1 construction beginning in 2026. V4 Superchargers deliver up to 500 kW of peak power — double the output of V3 — and are designed to handle the higher charging demands of next-generation Tesla vehicles and the broader EV market.

🔭 The BASENOR Take

The 400-stall announcement deserves to be read carefully. Tesla isn't just adding more stalls — it's rethinking what a charging station can be. A six-phase construction plan suggests this is a permanent, purpose-built charging destination, not an opportunistic parking lot addition. Think of it less like a gas station and more like an airport terminal for EVs.

For everyday owners, the immediate impact is reduced wait times at busy corridors. Tesla's existing network already handles peak-hour congestion reasonably well, but holiday weekends and popular road-trip routes still produce queues. A facility of this scale — even just Phase 1 — acts as a regional pressure valve, absorbing demand that currently backs up across multiple smaller stations.

The V4 hardware choice is equally significant. At up to 500 kW peak output, these stalls are future-proofed for vehicles that don't exist yet. Current Tesla models can't fully utilize 500 kW, but the infrastructure will be ready when they can. It's the same logic Tesla used deploying V3 before any car could max it out — build ahead of demand, not behind it.

The phased construction approach also tells you something about scale and ambition. Six phases implies a multi-year buildout with the flexibility to adapt as EV adoption grows. Tesla is essentially building a charging campus. The location hasn't been officially confirmed in the source tweets, but the project's existence and scope are now on the record. Keep an eye on charging news as Phase 1 details emerge later this year.
