11 Vegetation Management Inventory System System Deployment System Live August 28, 2007 Cost to Develop $4, Hardware Costs $22, Software Costs $3, Conception to Deployment 2 Months Results of Deployment 1 ½ Months to Inventory 100 miles of the VELCO System. Similar to previous years. c 1700 Acres of Right of Way c 951 Danger Trees c 408 Special Trees

12 What is the Data/System Being Used for? Field Reference: Cost per Acre, Property Owner Interaction, budget forecasting Development of Annual Work Plan as Required by NERC (FAC-003-1) Herbicide Application Permits Environmental Compliance Vegetation Contractors Reference: Creating Bids and Performing Work Contractor Work Verification Pole Treatment Contractors Reference Outage Dispatching

13 Benefits of System Identified After Deployment Mapbooks Created from Data is Used by Other Departments Helicopter Line Patrol System Has Been Adopted by Telecommunications Department and Line Crew System May be Adopted by other Distribution Utilities In-House Technical Support Future of the System The System will be Copyrighted Under the Name, VELCO VIP TM Select Type of Work to be Performed When Application Launches (ROW Patrol) Integration with a Multi-User Geodatabase Integration of Laser Range Finders???

14 Transmission Owner Operator Forum (TOOF) Review The Forum is chartered by the NERC Board of Trustees, and complements NERC s mission and reliability standards. The Forum s mission is to promote the highest levels of reliability to promote excellence in the operation of the electric transmission system. During the week of October 6 th through the 10 th, 2008, VELCO was the subject of the first TOOF Review. VELCO s s Integrated Vegetation Management GIS Based Work Plan Received a Superior Practice Designation. Picture from TOOF Website
