Scottish and Southern Electricity Networks
We own • one electricity transmission
network
• two electricity distribution networks
106,000 substations
128,000 km of circuit
100+ submarine cable links
across one third of the UK landmass.
Serving 3.5 million customers

NTVV Project metrics • Focusing on the LV Network
• Bracknell and the surrounding Thames Valley area
“by better understanding our customers and the loading on the network, we can build a model of the low
voltage network and use this to better anticipate and manage the impact of low carbon technology take-up
scenarios, allowing timely and targeted investment decisions, minimising disruption and costs to customers”

SSEN Use of Demand Response
• TVV ◦ Learning into: customer engagement, technicalities, network impact, factors
influencing reductions, analysis
• Constraint Managed Zones (CMZ) ◦ Peak electrical demand under post-fault conditions managed through the use of
demand reduction or demand shifting techniques, provided as a managed service to SSEPD by CMZ Supplier
CMZ Service
