Decoding Gigafactories: The future of electric vehicles

Gigafactories are reshaping how the world produces electric vehicle batteries, with facilities now spanning millions of square feet and requiring billions of dollars to build. This article answers the questions people actually ask about Gigafactories: what they are, how big they get, where they’re being built, and what it takes to bring one into production.

What is a Gigafactory?

A Gigafactory is a large-scale factory that produces batteries for electric vehicles and other applications, like grid storage. While some Gigafactories also produce EVs themselves, their primary focus is battery manufacturing. These factories are central to meeting the growing demand for EVs and accelerating the transition to sustainable energy.

How big is a Gigafactory?

Gigafactories are, as the name suggests, enormous. They can span millions of square feet, comparable in size to multiple large warehouses or even a small town. Tesla’s Nevada Gigafactory, for example, covers 5.4 million square feet, one of the largest buildings in the world by footprint. These vast spaces accommodate large-scale production lines, extensive storage areas, and research and development centres.

Why is it called a Gigafactory?

The “giga” refers to gigawatt-hours (GWh), a unit of energy. A gigawatt is a billion watts, and a gigawatt-hour represents the energy delivered by one gigawatt of power over one hour. Gigafactories aim to produce batteries with storage capacity measured in gigawatt-hours, hence the name, reflecting the scale of both production and energy output. The term was popularised by Tesla.

Where are most Gigafactories located?

A global map of Gigafactories is constantly evolving. More than 240 are operational worldwide today, with the total expected to exceed 400 by 2030, according to Benchmark Mineral Intelligence. A snapshot by region:

• China: home to seven of the world’s ten largest battery makers, and controls nearly 70% of battery cell pipeline capacity, with a vertically integrated supply chain from raw materials to finished batteries.
• Europe: Germany, Hungary and France together hold over half of the 1.2 TWh pipeline capacity projected for 2030. Poland is home to LG Energy Solution’s Gigafactory in Wroclaw, one of the largest in the world.
• The UK: Nissan operates a battery manufacturing facility in Sunderland, AESC is expanding its Sunderland facility to 15.8 GWh, and Tata’s Agratas Gigafactory in Somerset is being built for 40 GWh of annual capacity, with production now targeted for late 2027 following construction delays.
• North America: the 2022 Inflation Reduction Act’s manufacturing incentives drove substantial investment in the region’s battery supply chain, though federal EV purchase tax credits that had supported demand ended in September 2025 under subsequent legislation, with EV sales down 28% in the following quarter.

What does it take to equip a Gigafactory?

Getting a Gigafactory into production is as much a delivery challenge as a technology one. Battery cell and module production lines rely on highly specialised equipment, sourced from multiple suppliers, that must be installed and commissioned to exacting tolerances, often in phases, as construction and production run in parallel. Delays at this stage are what typically push back a facility’s actual start of production. In one of our recent projects, we supported the integration of next-generation battery technology into an active Gigafactory in Kentucky, dismantling, relocating, and reinstalling 3,506 individual equipment items for a joint venture between a major automaker and a Korean battery manufacturer, without stopping the rest of the facility’s production.

Coordinating that scale of equipping work usually means managing several specialist contractors and equipment suppliers in parallel, each working to their own schedule, while construction on later phases of the building may still be underway. In a Gigafactory build, a delay from any one of those parties can hold up the whole programme, since production lines are typically interdependent rather than independent. Our own project management approach on installation projects like this keeps planning, scheduling and delivery under one point of accountability throughout.

What does it cost to build a Gigafactory?

Building a Gigafactory is a multi-billion dollar undertaking. Estimates vary widely depending on size, location and technology, but costs commonly run into the billions. Tesla, for example, has invested $6.2 billion in its Nevada Gigafactory since 2014, with a further $3.6 billion committed for additional expansion, covering construction, manufacturing equipment and sustainable energy infrastructure.

How many batteries can a Gigafactory produce in a year?

Production capacity is typically measured in gigawatt-hours (GWh) of battery output per year. Tesla’s Nevada Gigafactory targets up to 35 GWh of battery cells annually, enough to power approximately 500,000 electric vehicles. Some planned Gigafactories aim for annual capacity exceeding 50 GWh.

What about energy and water consumption?

Gigafactories are energy-intensive operations that require substantial electricity and water for manufacturing. Many are increasingly turning to renewable energy sources such as solar and wind to reduce their environmental footprint, alongside water recycling and treatment systems to manage consumption. The industry continues to work on reducing its environmental impact.

How safe are Gigafactories?

Safety is a core consideration in Gigafactory operations. These facilities handle potentially hazardous materials, requiring rigorous safety protocols and trained personnel to prevent accidents and protect worker wellbeing. During construction and equipping specifically, this extends to every contractor and installation team on site. Our own approach to health and safety on installation projects is aligned to ISO 45001, with dedicated oversight from mobilisation through to handover.

The future of Gigafactories

Gigafactories are a cornerstone of the future of transportation and energy, and demand for them will keep pace with EV growth. Advances in battery technology and manufacturing process will continue to drive investment, with more facilities expected closer to raw material sources and consumer markets, further supporting the shift to cleaner, more sustainable energy and transport. The Gigafactory represents a significant investment in that future, paving the way for a world powered by clean energy and electric mobility.
