Tenova and GE Vernova selected to supply world’s largest electric arc furnace to Nippon Steel’s Yawata Works
Nippon Steel Corporation has picked Tenova, teaming up with GE Vernova, to supply what’s going to be the world’s largest Consteel® Electric Arc Furnace — a record-setting installation headed for the steelmaker’s Yawata Area at Kyushu Works in Japan. The project marks a significant move in Nippon Steel’s decarbonization strategy and pushes electric arc furnace technology further than it’s ever gone at industrial scale.
Record-breaking EAF contract awarded to Tenova and GE Vernova
This contract is a notable moment for both companies. Tenova, a specialist in sustainable technology for metals and mining, will supply its Consteel® Electric Arc Furnace — an already well-established platform in modern steelmaking — at a scale no one has tried before. GE Vernova joins as a key technology partner, bringing its Direct Feed system to serve as the furnace’s primary power supply.
The installation site is Nippon Steel’s Yawata Area, part of Kyushu Works in southern Japan. Yawata carries deep historical significance in Japanese steelmaking, which makes it a fitting home for a project of this ambition.
EAF steelmaking’s share of global production has been growing steadily, driven by decarbonization pressure, scrap steel availability, and improving technology.
Why Nippon Steel is investing in electric arc furnace technology
The steel industry is under serious pressure to cut carbon emissions. Traditional steelmaking has long relied on blast furnaces that burn coking coal — a process that produces significant volumes of CO2. Electric arc furnaces take a different route, using electricity to melt scrap steel or other iron sources, which can dramatically cut emissions per ton of steel produced, especially when powered by cleaner energy.
The global shift from blast furnaces to EAF steelmaking is picking up speed. Steelmakers across Europe, Asia, and North America are rethinking their production infrastructure as climate regulations tighten and carbon costs climb. Nippon Steel is no exception, having set decarbonization targets that require transitioning key sites to lower-emission processes.
Investing in a record-scale EAF at Kyushu Works signals a structural commitment to changing how Nippon Steel makes steel — not just fine-tuning what it already has.
Role of GE Vernova’s Direct Feed system in the project
Running the world’s largest EAF demands an equally capable power supply. GE Vernova’s Direct Feed system is built specifically to handle the high and rapidly fluctuating electrical demands that large-scale electric arc steelmaking creates — managing that kind of load reliably is a serious engineering challenge in its own right.
GE Vernova’s role here isn’t secondary. The Direct Feed system is the primary power source for the furnace, so its performance sits at the center of the project’s success. Any instability or inefficiency would hit steelmaking output and energy costs directly.
The Consteel® continuous charging process feeds scrap into the furnace in a steady stream rather than in batches, keeping the arc more stable and reducing energy spikes. Paired with a power system built for industrial-scale demands, the two technologies are designed to work together — not just alongside each other — to maximize overall energy efficiency.
Background: Tenova, GE Vernova, and the global EAF market
Tenova has built its name as a provider of sustainable solutions for metals and mining. Its Consteel® EAF platform is one of its flagship technologies — a continuous charging system adopted at steelmaking facilities around the world. The Yawata Works project is the largest deployment of that platform to date.
GE Vernova operates as a global energy technology company with broad expertise in industrial power systems, spanning power generation, electrification, and grid solutions. Those capabilities translate directly into the demanding power environment of large-scale EAF steelmaking.
The broader market context matters here. EAF steelmaking’s share of global production has been growing steadily, driven by decarbonization pressure, scrap steel availability, and improving technology. Steelmakers that once relied almost entirely on integrated blast furnace routes are now committing serious capital to electric alternatives — and that trend isn’t slowing down.
The Yawata Works project pushes the boundary of what EAF technology can do at scale. It’s not just large — it’s the largest. That distinction means it’ll likely serve as a reference point for future projects as the industry continues moving in this direction.
What this project means for the future of large-scale EAF steelmaking
To pull the key points together: Nippon Steel has awarded Tenova and GE Vernova a contract to supply the world’s largest Consteel® Electric Arc Furnace at its Yawata Area, Kyushu Works. Tenova leads the furnace supply itself, while GE Vernova’s Direct Feed system handles the primary power requirements. The project reflects Nippon Steel’s broader push to cut carbon emissions from its steelmaking operations — a goal shared by major producers globally.
For Tenova and GE Vernova, the contract validates both companies’ technologies at an unprecedented scale. For the steel industry as a whole, the Yawata Works installation may set the benchmark for what large-scale, lower-emission steelmaking looks like in the years ahead.
