Please add information or make comments on the map from the meeting

This information is currently being updated by stakeholders. The goal is to represent the INCREMENTAL LOAD GROWTH and POTENTIAL RESOURCES through the planning window of 2017.

Given the long-lead requirements of planning, permitting, and constructing major transmission lines, NTTG would like to begin the process where clear needs exist. The formal planning cycle starting later in 2007 will help refine project proposals and identify additional requirements in an adaptive, iterative approach beginning with the list of Fast Track Transmission Projects.

example (you can update and copy on to the map)

100 MW (LOAD)

500 MW (coal, gas, wind – choose type)
