Nippon Steel selects Tenova and GE Vernova to install world’s largest electric arc furnace at Yawata Works
Nippon Steel Corporation has handed Tenova a contract to supply what will be the world’s largest Consteel® Electric Arc Furnace at its Yawata Works facility in Kyushu, Japan. Tenova is partnering with GE Vernova, whose Direct Feed system will power the record-breaking installation.
Nippon Steel awards record EAF contract to Tenova and GE Vernova
The scale here is what sets this apart from anything built before. The Consteel® Electric Arc Furnace headed to Yawata Works will be bigger than any existing EAF on the planet — not just an engineering milestone, but a strategic statement from one of the world’s major steel producers.
Tenova, a leading provider of sustainable solutions for the metals and mining industries, will serve as the primary supplier. GE Vernova joins as the key technology partner, bringing its Direct Feed system to handle the high-power electrical supply the furnace needs. It’s one of the most significant contracts the global steel industry has seen in recent years.
Yawata carries real weight in Japanese steelmaking history — it’s one of the first places where modern steel production took hold in Japan.
The installation site is the Yawata Area at Kyushu Works. Yawata carries real weight in Japanese steelmaking history — it’s one of the first places where modern steel production took hold in Japan. Putting record-scale electric arc furnace technology here says a lot about how seriously Nippon Steel is approaching its shift away from conventional production methods.
Why Nippon Steel is investing in electric arc furnace technology
Steel production ranks among the most carbon-intensive industries on the planet. Traditional blast furnace operations lean heavily on coal-based processes, pumping out significant CO2 per ton of steel. As climate targets tighten worldwide, steelmakers face growing pressure to find lower-emission paths forward.
Electric arc furnaces offer a real alternative. Instead of burning coal to melt iron ore, EAFs use electrical energy — typically to melt recycled scrap steel. That shift can cut the carbon footprint of steelmaking considerably, depending on what’s powering the furnace.
Nippon Steel’s move fits a wider industry pattern. Steelmakers across Europe, North America, and Asia have been ramping up EAF investment as a core decarbonization strategy. Japan’s steel industry, built around large-scale integrated blast furnace operations, has been slower to pivot — but that’s changing. This contract suggests Nippon Steel isn’t just signaling ambition. It’s acting on it.
How the Consteel EAF and GE Vernova’s direct feed system work together
Tenova’s Consteel® technology has one feature that really distinguishes it from standard EAF designs: a continuous scrap-feeding conveyor. Rather than loading scrap in large batches, Consteel feeds material in a steady, controlled stream — improving energy efficiency and cutting electrode consumption, two things that matter enormously at this kind of industrial scale.
Continuous feeding also stabilizes how the furnace runs. Batch charging creates spikes in energy demand and temperature swings; Consteel’s conveyor approach smooths those out, making the furnace easier to operate consistently and reducing wear on critical components over time.
GE Vernova’s Direct Feed system is built for exactly this kind of high-capacity demand. Running a furnace this large requires a reliable, high-capacity electrical supply, and the combination of Consteel’s continuous feeding with that power technology is designed to optimize energy use and production throughput at Yawata — two goals that conventional steelmaking setups often struggle to balance simultaneously.
Background: Tenova, GE Vernova, and the global EAF market
Tenova is a global supplier focused specifically on sustainable technology for metals and mining. The company has delivered EAF installations across multiple continents, building a solid track record in large-scale steelmaking projects, and its Consteel® technology is one of its flagship offerings in the electric steelmaking space.
GE Vernova is an energy technology company spun off from General Electric, with a focus on power generation and electrification — putting it right at the intersection of industrial decarbonization. Partnering with Tenova on this project positions GE Vernova in a fast-growing market for high-power industrial electrification.
That market keeps expanding. The global EAF sector has grown steadily as steelmakers look for alternatives to blast furnace production, and corporate and national climate commitments continue pushing investment in this direction. EAF economics have also become more competitive as scrap availability and electricity infrastructure improve in key markets.
Japan is a particular case. Its steel industry built its reputation on large, efficient integrated blast furnace operations, and moving away from that model takes serious capital and long-term planning. What Nippon Steel is doing at Yawata Works suggests that transition is now underway in earnest.
What this project means for Nippon Steel’s decarbonization path
This contract pulls together several distinct elements: a record-breaking furnace, a proven continuous-feeding technology, and a high-capacity power system from a major energy company. Nippon Steel is making a significant bet on electric arc steelmaking at one of its most historically important sites.
When complete, the Yawata installation will be the world’s largest Consteel® EAF. For Tenova and GE Vernova, it’s a high-profile demonstration of what their combined technologies can deliver at scale. For Nippon Steel, it’s a concrete step toward decarbonizing operations that have long depended on coal-intensive processes.
