Ensuring a reliable and sustainable power supply is a crucial aspect of infrastructure development. This blog post details the essential scope of work and key deliverables to be addressed during the scope of work and due diligence required for utility power supply across India.
🧭 1. Scope of Work in Due Diligence for Utility Power Supply
A comprehensive due diligence report should cover the following components:
🔍 Energy Market Overview
📍 Site Information
🔌 Source of Power Supply & Redundancy
⚙️ Utility Connection Scheme & Right-of-Way
💸 Connection Cost Breakdown
🗓️ Connection Delivery Timeline
📝 Application Process & Documentation
📑 CEIG (Chief Electrical Inspector to Government) Requirements
🌐 2. Energy Market Overview
Energy Market Overview for Utility Power Projects
Understand the macro energy landscape where your project is located:
Installed generation capacity and ongoing/upcoming generation projects
Distribution network details, including consumer categories and energy consumption patterns
Grid connectivity at 230 kV & 400 kV levels.
Substation locations, capacities, and interconnectivity
🗺️ Tip: Use utility board reports data for accurate market figures
The Southern Region’s power infrastructure is well-integrated through 230 kV and 400 kV transmission networks connecting Tamil Nadu, Andhra Pradesh, Telangana, Karnataka, and Kerala. You can explore the Southern Regional Grid Maps published by SRPC for detailed layouts of transmission corridors, substations, and inter-regional connectivity.”.

📌 3. Site Information
Collect and document the following:
Site address, coordinates (latitude/longitude), and phase-wise power requirements
Locality-specific power distribution map
History of power outages (especially during monsoons/floods)
Existing/planned shutdown strategies adopted by nearby substations
Any special locality-based observations or restrictions
⚡ 4. Power Supply Sources
Source of Power Supply for Utility Power Due Diligence
Analyze and recommend the best power supply options:
Number of supply sources required
List of nearby substations with:
Operational status
Transformer capacity
Existing load and spare capacity
Peak demand reached
Major consumers connected
Expansion feasibility
Distance to site and connection feasibility (OH/UG cables)
Single Line Diagram (SLD)
Right-of-Way issues
Recommendation of best-fit supply source with pros & cons

📥 5. Application Process & Timeline
🔧 5.1 Steps to Apply for Utility Power
Estimate exact demand & propose supply voltage level
Identify nearest grid substation (with help from utility board)
Survey proposed cable/tower route
Finalize metering point and location layout
Coordinate on technical specifications (CT, PT, GIS, breakers, cables, etc.)
Land gifting process (if applicable for gifting by consumer for forming a new substation on-site by Utility)
🔄 Utility power connection procedure:
Submit EHT application with documents
Site inspection and load flow study by utility board
Pay Earnest Money Deposit (EMD) after feasibility clearance
Receive demand sanction and technical estimate
Execute agreement and self-execution approvals
Conduct drawing approvals (GA/GTP)
Arrange factory inspections and on-site testing
Submit CEIG safety certificate and completion documents
Utility board installs metering system and powers up site
