Why a dictionary existsGB energy governance uses 400+ acronyms daily

A single Ofgem consultation can reference forty acronyms without defining most of them. The dictionary closes that gap.

GB energy is one of the most acronym-dense policy areas in British public life. A typical Ofgem consultation response references BSC, CUSC, DCUSA, STC, UNC, SEC, CEARA, RIIO, ECO, EMR, CfD, CM, CP2030, MHHS, DIP, DCC, DNO, DSO, ENA, SECAS, NESO, LTDS, CIM, SHACL, GSP, BSP, BMRS, FES, and more. No single reader knows them all.

The dictionary consolidates 220 regulated terms in one place. Each entry is GCSE-accessible at the top and technically precise at the bottom. Every entry cites the primary source (Ofgem, NESO, Elexon, DESNZ, ENA, Xoserve, National Gas) and carries an as-of date. Out-of-date entries are flagged, not silently corrected.

The goal is not completeness. It is trust: every term should have a single authoritative definition so that any two people discussing a topic can check they mean the same thing.
