Planning distribution systems

When planning distribution lines, engineers and planners consider many factors, including:

• amount of power the line must carry
• length of the line
• required reliability levels
• operation and maintenance
• physical clearances for routing the line
• potential impacts to the environment and communities
• costs to build, operate and maintain the line
• how the line fits into the overall electricity system

In planning new facilities such as substations, electricity distribution companies research the area to identify a proposed site and alternate sites. Before applying for a government license and permit to build and operate the facility, they carry out public consultation to understand what concerns or questions people who work and live in the area may have regarding each proposed site.
