Global Energy Monitor

Current Capacity (TTPA) values "0" that means >0.   Citation: “Global Blast Furnace Tracker, Global Energy Monitor, April 2024 (V1) release.”  GEM Plant IDWhich iron or steel plant in the GSPT the unit belongs to. A unique GEM identifier is assigned to each plant. Uses format P10000012XXXX where P stands for "plant", and XXXX increases with every new plant added to the GSPT. GEM Unit IDA unique GEM identifier is assigned to each blast furnace unit. Uses format U10000014XXXX where U stands for "unit", and XXXX increases with every new unit added to the tracker. "N/A" indicates the plant has blast furnace capacity but an unknown number of units.Unit NameIf the furnace has a colloquial name or unit name (may be a letter or number) assigned to it by the plant operator. "unknown" indicates that the unit has no known name.GEM wiki pageLink to GEM wiki page in English.Unit StatusCategories are "announced", "construction", "operating", "operating pre-retirement", "mothballed", "cancelled", and "retired".Announced DateDate of announcement/proposal of furnace in the format YYYY-MM-DD.Construction DateDate that construction of the furnace began in the format YYYY-MM-DD.Start DateFurnace start date in the format YYYY-MM-DD.Retired DateDate that blast furnace was permanently closed, either after being disassembled or after a period of inactivity (after 5 years of “mothballed”), in the format YYYY-MM-DD.Unit AgeFurnace age in years. Calculated between furnace start date and the data release year, 2024, or the retired year where known for retired furnaces.Furnace ManufacturerManufacturer of furnace. (example: Primetals Technologies)Furnace Type/ModelFurnace model/technology process used. (example: Midrex, Corex, Finex, HIsarna, Siemens)Current Capacity (ttpa)Production capacity of unit in thousands of metric tonnes per annum.Current SizePhysical furnace size. (example: 3000 m3)Current Size UnitTypically cubic meters (m3) for blast furnaces.Most Recent ReliningMost recent relining date in format YYYY-MM-DD where unit has a known relining. "unknown" indicates the unit has no known relinings or only has relining events with no known dates. This date is the stop date of the relining or the start date if stop date is unknown. Further detail on relinings can be found in the "Furnace Relinings" sheet.

Uses format U10000014XXXX where U stands for "unit", and XXXX increases with every new unit added to the tracker.Relining StatusCategories are "complete", "in progress", "planned", or "cancelled".Relining TypeType of relining performed on blast furnace unit. Categories are "full", "partial" and "unknown".Furnace Relining Start DateDate that furnace stops operations and transitions to maintenance/relining work in the format YYYY-MM-DD.Furnace Relining Stop DateDate that furnace resumes operations and begins transition back to ironmaking operations in the format YYYY-MM-DD.Furnace Relining Duration (Days)Approximate number of days that blast furnace unit was stopped to undergo maintenance.Furnace Relining NumberNumber of the furnace relining if known. Relining CostApproximate investment cost of equipment, installation, upgrades, technology, etc for relining work. Does not include revenue lost during relining of blast furnace. Only numerical digits with currency type found in the Relining Cost Unit field.Relining Cost UnitISO three-letter currency code unit for relining cost. Relining Capacity ExpansionIf applicable, furnace expansion as a result of the relining maintenance work. "N/A" if known that relining will not result in capacity expansion. "unknown" if not known whether relining will result in capacity expansion.Relining Capacity Expansion UnitTypically cubic meters (m3) for blast furnace volume.
