The series for electricity invoicing in Catalonia is built by the aggregation of invoicing in KWh at the all-inclusive rate (regular market) and access/toll rate (free market) of the main electricity utility operating in Catalonia (FECSA-ENDESA), carried out by the Catalan Energy Institute and the Ministry of Economy and Finance.
The data for monthly electricity invoicing refer to the invoices issued in a particular month. These invoicing data may correspond to real consumption in the previous month or previous two months.
