SSEN Generation Availability and Network Capacity — Methodology Statement

notes
["Demand quantities are MVA and generation quantities MW, as the column names state; nothing is converted.","Headroom is published as text: every GSP row reads \"N/A\" for both headrooms, kept as an unknown value with SSEN's label.","SSEN states no firmness for its estimated headroom; firmness is unknown.","The asset id is SSEN's AssetID (\"E - AMEM - 01\"), which doubles as the GSP grouping / default order.","Maximum and minimum observed gross demand (MVA), fault ratings and levels (kA), transformer nameplate ratings, TIA threshold, reinforcement works and the demand/generation RAG status are the source's own facts, kept as asset attributes or value details, not as capacities.","Upstream GSP/BSP are names; a parent is linked only when exactly one row carries that name."]
