We put some words together on this question some time ago. See if this helps.
Planning is an art that requires much more than excellent technical expertise and knowledge of the distribution system. A planning engineer, while having top-notch engineering skills and analytical skills, must also:
• Understand project management, and probability and statistical analysis.
• Understand the behavior of government and business and their impact on utility operations.
• Have good communication skills. They will be required to educate and influence other utility personnel.
• Be motivated champions of their plans. They need to speak out clearly on issues of importance.
• Be well trained in the management of their resources.
• Be willing to compromise. There are non-engineering factors that sometimes outweigh pure economics and dictate changes to the plan, however perfect, it’s engineering.
The distribution planning engineer has two primary functions:
• to develop a program which provides for orderly and timely modifications to the electric system to insure an adequate, economical, reliable and universal supply of electric power to all customers.
• to maintain a substantial level of involvement in the operation of the installed system to insure the maximum asset utilization and return on our existing facilities.
Hopefully we'll get some feedback from other companies to see if they agree with what I wrote.
