HT/LT Power Network Route Survey – NTPC / CESU

Project Overview

The HT/LT Power Network Route Survey project was executed by SpatiEdge Technologies Pvt. Ltd. to support NTPC and CESU in planning, designing, and implementing high-tension (HT) and low-tension (LT) power distribution networks. The project focused on delivering accurate, geo-referenced route alignments and corridor mapping to ensure efficient infrastructure development and minimize implementation risks.

Client / Stakeholders

• NTPC (National Thermal Power Corporation)

• CESU (Central Electricity Supply Utility), Odisha

• Odisha State Transmission and Distribution Departments

Project Objectives

• Conduct precise route surveys for HT and LT power lines

• Optimize transmission and distribution network alignments

• Ensure safety, regulatory compliance, and minimal land acquisition issues

• Provide accurate spatial data for planning, design, and monitoring

Scope of Work

• DGPS-based field surveys to capture transmission and distribution corridor coordinates

• Detailed mapping of poles, towers, substations, and right-of-way (ROW) alignments

• Integration of survey data into GIS for spatial analysis and planning

• Validation of existing route plans and identification of route optimization opportunities

• Preparation of maps and technical reports for departmental approvals

Methodology & Technical Approach

SpatiEdge employed a survey-first methodology using DGPS/GNSS systems to capture high-accuracy coordinates for HT/LT network routes. Field data was integrated with GIS platforms to create layered maps representing routes, poles, towers, substations, and associated infrastructure. Alignment optimization and clearance analysis were performed to ensure regulatory compliance and operational efficiency.

Technologies & Tools

• DGPS / GNSS Survey Systems

• Total Station (for detailed site verification)

• GIS Platforms (ArcGIS / QGIS)

• CAD–GIS integration for engineering design support

• High-resolution satellite imagery for route validation

Key Deliverables

• Geo-referenced GIS layers of HT/LT power routes

• Pole, tower, and substation location maps

• Right-of-way and corridor alignment reports

• GIS-ready datasets for planning and monitoring

• Technical documentation for approvals and project planning

Impact & Outcomes

• Optimized transmission and distribution network planning

• Reduced land acquisition, alignment, and implementation risks

• Improved accuracy of power network maps and asset records

• Strengthened planning and monitoring capabilities for NTPC and CESU

• Supported efficient and sustainable expansion of Odisha’s power infrastructure
