Tamil Nadu Power Distribution Corporation Limited (TNPDCL) is preparing to map its entire electricity distribution network using Geographic Information System (GIS) mapping technology.
The fresh push to improve reliability comes as frequent power cuts persist in several parts of Tamil Nadu despite the state reporting an adequate electricity supply.
The move is aimed at helping engineers detect faults faster, reduce outage durations and improve planning for future infrastructure upgrades. The initiative forms part of the state’s wider digital transformation of its power network.

GIS Mapping to Create a Digital View of the Power Network
The GIS project will digitally map every major asset across the distribution network, including substations, feeders, transformers, electric poles and consumer connections.
Officials believe this will give field teams a clearer picture of the network, making it easier to trace faults, plan maintenance work and restore electricity more quickly after disruptions.
The mapping exercise is also expected to strengthen planning for new electricity connections, future network expansion and asset management. By integrating GIS with the utility’s digital systems, engineers can access real-time information instead of relying on manual records, reducing duplication and speeding up decision-making.

Part of a Wider Drive to Tackle Recurring Power Cuts
The GIS rollout comes as TNPDCL has intensified efforts to address repeated power interruptions across the state. Earlier this month, the utility launched a Repeat Tripping Elimination Programme (RTEP), directing engineers to identify substations, feeders and transformers that have experienced repeated faults over the past six months. Areas are being prioritised based on outage frequency, the number of consumers affected, impact on essential services and operational issues.
The focus is on permanent engineering solutions rather than temporary repairs.
The initiative follows recent government announcements to strengthen Tamil Nadu’s power infrastructure. The state has also approved the construction of 231 new substations, along with upgrades to 121 substations already under development.
Authorities have also announced plans to recruit 15,058 electricity workers to improve field operations & maintenance.
