What is a Gigafactory?

The term "Gigafactory", originally popularized by Tesla, refers to battery manufacturing plants capable of producing over 1 GWh (roughly equivalent to 15,000 electric vehicle battery packs) annually.

Today, these facilities are typically built with capacity goals ranging around 40 GWh. However, companies like Tesla continue to push the boundaries, aiming for massive multi-phase expansions up to 100 GWh—or even an unprecedented 250 GWh—per facility. To put this in perspective, prior to the mainstream Gigafactory era in the 2010s, global battery factories rarely exceeded 2-3 GWh.

I track a comprehensive list of existing and planned Gigafactories worldwide. Currently, there are well over 100 projects tracked across the globe, scaling massively to meet global emission mandates by the end of the decade.

In terms of scale, out of the roughly 90 million cars produced globally in 2025, a growing chunk is fully electric. Current global gigafactory announced capacity surpasses 2.3 TWh, which can support over 35 million EVs per year. Looking ahead to 2030, projections point toward an astounding global capacity of 6,000 to 8,000 GWh (6-8 TWh), which would easily support the complete transition of the global auto market.

Who are the Key Players?

While early Gigafactories were heavily defined by exclusive joint ventures (like the massive Tesla-Panasonic partnership), the landscape in 2026 is much more diverse. The global capacity is dominated by massive international battery makers, many of which operate joint ventures with major automakers.

The top leaders driving total planned global capacity today are:

1. Northvolt (Leading the charge in European battery manufacturing, 12%)

2. CATL (Global incumbent with massive presence in China and Europe, 11.6%)

3. Tesla (Pioneering gigafactories globally, 11.1%)

4. Nissan (Significant joint ventures and planned footprint, 9.9%)

5. LG Energy Solution (Major supplier for GM, Hyundai, and others, 9.0%)

6. Total (Emerging powerhouse via the ACC joint venture, 7.9%)

Other significant battery manufacturers like SK Innovation, BYD, Panasonic, and Farasis contribute heavily to regional expansions. Meanwhile, automaker-driven programs are surging, with massive internal or partnered factory initiatives from Ford, Volkswagen, Stellantis, General Motors, Daimler, Toyota, Geely, Tata, Rivian, Nio, Xpeng, and global electronics manufacturing giants like Foxconn.

Where are they built?

Tracking capacity location reveals a massive global race. Based on our tracking, Europe leads with nearly 40% of planned global capacity, balancing enormous investments from players like Northvolt and joint ventures like ACC. However, thanks to heavy local manufacturing subsidies over the past few years (such as the US Inflation Reduction Act), North America is rapidly closing the gap with 28% of capacity and dozens of new plants spinning up.

China remains a critical player contributing around 27%, producing an outsized majority of the fully operational battery cells today despite other regions rapidly gaining ground in planned capacity. You can see a map of all gigafactories here to visualize exactly where these massive factories are physically located.

When to expect them?

According to recent industry assessments from groups like Benchmark Mineral Intelligence and the Federal Reserve Bank of Dallas, capacity growth is steep.

The US is on track for well over 1.5 TWh by 2030, a monumental jump from almost nonexistent capacity a decade ago. Europe's annual capacity expects to reach past the 1 TWh mark similarly. Yet, all this still pales in comparison to China, which remains forecasted to account for upward of 4-5 TWh by the early 2030s. The challenge now lies largely in material supply constraints and operational workforce scaling, rather than simply factory planning.
