Note that the CSV downloads on the BMRS do not include headers within the column names. Instead, the data structures are defined in the NETA Interface Definition and Design (IDD): Part 1. The data format for Instantaneous Generation by Fuel Type (FUELINST) and Half-Hourly Generation by Fuel Type (FUELHH) are defined in Sections 4.11.21 & 4.11.22 of the IDD; here the Fuel Types are ordered as follows: CCGT, OIL, COAL, NUCLEAR, WIND, PS, NPSHYD, OCGT, OTHER, INTFR, INTIRL, INTNED, INTEW, BIOMASS. Alternatively, the XML downloads include Fuel Type names within the tags and users who require the Fuel Type names within the file can import the XML into a spreadsheet. The XML downloads also include tags to report interconnector totals per Bidding Zone.
