"In ColumbiaGrid, we now have the ability to resolve the three fundamental transmission questions: What transmission facilities should be built? Who should build them? Who should pay for them? With ColumbiaGrid's independent staff and process to resolve disputes, we can answer these questions effectively and in a timely fashion to facilitate our region's new resource development needs."
