Scottish and Southern Electricity Networks Tech Stack

Electricity distribution network operator for 3.9M UK customers across central southern England and northern Scotland

Utilities Perth, Scotland 1,001–5,000 employees Public Company

Scottish and Southern Electricity Networks (SSEN) operates 130,000km of overhead lines and underground cables serving 3.9 million homes and businesses. The tech stack reveals a capital-intensive, safety-critical operation: heavy reliance on SCADA, PLCs, and industrial protocols (DNP3, IEC 61850) for real-time grid control, paired with enterprise systems (SAP, Maximo) for asset management and ArcGIS for network mapping. Engineering dominance in active hiring (162 of 273 roles) and dense project portfolio—substation upgrades, BESS installation, overhead line maintenance—reflect the continuous physical infrastructure work required to maintain network reliability and support the net zero transition.
