FDE Times: At electric utilities, GIS and SCADA disagree for a reason — classify mismatches before you join them
A 5 November FDE Times guide for FDEs joining utility data: GIS stores the grid as designed and SCADA as operated, so an “open” vs “closed” switch is often intentional. Use CIM (IEC 61970/61968) as vocabulary, build an ID crosswalk, classify match / missing link / intentional switching / field check, then lock the object model before any dashboard.
A 5 November FDE Times guide walks through a first-week trap at electric utilities: joining GIS exports, SCADA tags and an asset register, then treating every state mismatch as a bug. GIS answers how the grid is designed to operate; SCADA answers how it is operating now — so intentional switching and stale mapping look similar until you separate them.
The piece points FDEs at CIM under IEC 61970 (EMS, topology, SCADA) and IEC 61968 (distribution, assets, GIS, metering) as a shared vocabulary even when the customer does not implement CIM literally. The practical sequence is crosswalk asset IDs to SCADA tags, keep normal vs measured state in distinct fields, classify devices into match / missing link / intentional switching / needs field check (using switching orders from the control room), and only then freeze an object model.
For FDEs reading energy-sector job ads, the guide’s takeaway is career-facing as well as technical: lead with which systems you reconciled topology between and how you classified mismatches — not a vague “data integration” line — because operational-system integration is repeatedly named as the hard part of ADMS-style deployments.
