Petronor Muskiz Refinery (Bilbao)

Capacity from the CORES "Spanish Refinery Capacity" workbook, sheet "Crude" (atmospheric distillation), row year 2025. Sheet header prints "Unit: thousands of tonnes"; workbook notes print "Figures to 31st December" and "Updated 30-07-2026". Workbook linked from https://www.cores.es/en/spanish-refinery-capacity. CORES is a Public Law Corporation under the Spanish Ministry for the Ecological Transition. The kt value was rescaled to Mt (same unit family, tonnes); no tonne-barrel conversion was performed. CORES prints 11000 thousand tonnes of crude for Bilbao in 2025. DISAGREEMENT: Petronor's own facilities page prints "a distillation capacity of 12 million tons per year (Mtm/year)" (https://petronor.eus/en/facilities/). Both sources describe distillation capacity, so this is a genuine conflict of published values: CORES (Tier 1, dated to 31 December 2025) 11 Mt/a versus Petronor (operator, page undated) 12 Mt/a. The CORES figure is in the capacity cells because it is dated and because the same register was used for every other Spanish site in this batch; the operator figure is recorded here rather than discarded. capacity_bpd left empty: no source I opened prints barrels per day for this site. owner=Repsol rests on the CORES workbook grouping the Bilbao column under the sheet and header "Repsol Group"; I did not open any page stating an ownership percentage, so no percentage is recorded. Operator name as filed in the EEA IED register for reporting year 2024: "Petroleos del Norte, S.A. (Petronor)". Commissioned year 1970 from the CORES workbook 'Start' sheet: "1970: Start of operations in the Somorrostro (Muskiz) refinery". The EEA IED register gives dateOfStartOfOperation 2006-06-05, clearly a permit date, not used. Coordinates are from the EEA Industrial Emissions Portal (IED Annex I activity 1.2 'Refining of mineral oil and gas'), reporting year 2024, read via the EEA DiscoData SQL API on 2026-09-22; see https://industry.eea.europa.eu/. Not operator-published.
