Methodology

Price: ESIOS indicator 600 (Spain). Demand: ESIOS indicator 1293 (peninsular). Mix: P48 schedule by technology (REE/ESIOS), best estimate at month close — metered generation is published later; the check against the most recent metered month shows differences below 1%. Peninsular scope, full calendar month.
