Steel
An extremely energy-intensive sector where the electric arc furnace, hot rolling and compressed air dominate consumption.
In steelmaking, energy is a major share of product cost and is spent mainly in three areas: melting and reduction (electric arc furnace or blast furnace), hot rolling and annealing, and auxiliary systems such as compressed air and oxygen generation. The electric arc furnace's load is highly volatile and directly affects the contracted demand and the electricity bill. Constantly changing charge mix also makes simple period-to-period comparisons of total consumption misleading, so normalization by tonnage and charge composition is essential.
Energy management challenges in steelmaking
Sharp swings in electric arc furnace load and their effect on demand charges and power factor
Heat losses from reheating and annealing furnaces due to leaks and degraded insulation
High graphite electrode consumption tied to charge quality and tap-to-tap time
Compressed air leaks along long rolling mill and melt shop lines
Constantly changing charge mix (scrap vs. direct reduced iron) that complicates specific energy comparisons
Concurrent production lines — steelmaking, hot rolling, cold rolling — with very different load profiles
Gita 50001 for steel
Real-time specific energy monitoring
Automatic calculation of specific energy per tonne of liquid steel and per tonne of rolled product, broken down by shift and line, for a realistic comparison of performance.
Multivariate EAF baseline
Regression modeling of electric arc furnace consumption against tonnage, charge mix and melt time to isolate genuine deviation from the normal pattern.
Demand deviation alerts
Early detection of contracted demand breaches and power factor drops, alerting the control room before the utility applies a penalty.
Compressed air leak tracking
Logging and prioritizing compressed air leak points across production halls by the value of energy wasted, to plan repairs.
Energy-per-tonne reporting
Automatic management reports on specific energy per tonne of liquid steel and finished product for production managers and senior leadership.

From leak repair and pressure optimization
A steel mill producing roughly one million tonnes a year, after deploying real-time demand monitoring and a multivariate EAF baseline, aligned its peak consumption pattern with the production schedule and measurably cut contracted-demand penalties over one full annual billing audit cycle.
