Power Projects Awarded Arc Flash Analysis for 206.25 MW Utility-Scale Solar Power Project
Strengthening Electrical Safety Across Large-Scale Renewable Energy Infrastructure
Power Projects has been awarded an Arc Flash Analysis assignment for a 206.25 MW utility-scale solar power project, supporting electrical safety assessment across the facility's transmission and distribution network.
The project involves a comprehensive evaluation of arc flash hazards across the solar generation facility, including the 220 kV pooling substation and the complete 33 kV solar collection system.
As part of the assignment, Power Projects will perform ETAP-based arc flash simulations, conduct site data collection, prepare engineering deliverables, and provide arc flash safety training for operating personnel.
This project further strengthens Power Projects' experience in delivering electrical safety engineering solutions for large-scale renewable energy developments.
Project Overview
The 206.25 MW solar power plant is connected through a 220 kV pooling substation.
Power Projects will carry out a detailed Arc Flash Analysis to assess electrical hazards across the complete network, determine incident energy levels, and establish safe working boundaries for maintenance activities.
The scope also includes field data collection and arc flash safety training to support safer operation and maintenance practices throughout the facility.
Project Scope
The Arc Flash Analysis covers the following key activities:
- Site data collection
- Arc flash hazard analysis
- Arc flash safety training
- ETAP network modelling
