Power Line Construction

Overview

Power transmission plays a vital role in the energy sector, equally important as power generation. The electricity produced at power plants must be conveyed over long distances to reach consumption centers via transmission lines and towers. To accommodate increasing demand, it is essential to expand the Transmission & Distribution (T&D) network, ensuring a reliable, stable, and secure energy supply. This necessitates careful and cost-effective planning of the transmission system. Currently, power transmission utilities utilize standard designs for constructing transmission lines to keep capital expenses low. However, delays in these projects can severely impact economic growth. Common challenges during the construction phase include layout modifications, land management issues, contractor problems, financing, and contract disputes.

This training offers essential knowledge for managing power line construction from electrical, civil, and health, safety, and environment (HSE) perspectives.
