A text-based Norwegian file format for exchanging metering values, in use in the power sector since long before Elhub.
Definition
A GS2 file states which metering pointThe fundamental unit in Elhub - the unique point in the electricity network where energy is measured and settled, identified by an 18-digit GSRN number. the values belong to, which period they cover, which unit they are in, and the status of each value. The format is older than the XMLExtensible Markup Language - universal markup language for structured data, standard in Elhub's Ediel messages.-based exchanges in the sector, and simpler: plain text in a file, with no envelope around it.
The format survives because it does one job well. Metering values arrive in bundles because they are collected in bundles, and one file per bundle fits that shape. GS2 is therefore still used inside the collection chain, among other places into the VEEValidation, Estimation, Editing - systematic process to ensure quality of raw metering data from electricity meters. engine, even where the market messages leaving the building are in entirely different formats.
GS2 is easily confused with Ediel and EDIFACT messages such as MSCONS, but they do different jobs. GS2 moves values between systems within one chain; MSCONS is a market message between market participants. A system can perfectly well take GS2 in and send MSCONS out, and many do exactly that.
In practice
