Significant Thermal Activity Increase at Sevilla Steel Plant Amid Rising Spanish Steel Production

Introduction

Riva Siderurgica Sevillana, located in Sevilla, Spain, operates under Riva Group, producing 1,300,000 tonnes of crude steel annually through electric arc furnace technology. The plant focuses on semi-finished and finished products, primarily supplying the construction sector amid recent buoyancy in steel demand.

Activity Trends Over Time

The thermal activity observed at the plant has shown a clear upward trend over recent months. Specifically, the electric arc furnace (EAF_0) demonstrated substantial growth:

The activity increased from 47.0% in November 2024 to a peak of 65.0% in March 2025, reflecting a significant operational uptick correlating with Spain’s broader steel production growth. This also aligns with the Spain increased steel production by 10.9% y/y in March article, which reported a robust recovery in output, particularly in response to strengthening demand from the construction sector.

Implications for Steel Buyers and Market Analysts

The heightened activity at Riva Siderurgica Sevillana signifies a positive outlook for steel supply stability, especially as Spanish steel production overall is gaining momentum, reaching 1.13 million tonnes in March 2025. With production levels rising in Spain, there are potential benefits for steel buyers in terms of availability, yet this also raises concerns about capacity constraints if demand continues to outpace production capabilities. Observing these thermal activity trends could provide critical insights into operational stability and supply chain dynamics within the steel market. As noted in the UNESID: Spanish steel output up 1.8 percent in Feb from Jan, indicators suggest ongoing strong growth across the sector, reinforcing the importance of monitoring Riva Siderurgica Sevillana’s productivity levels closely.
