3 Project Goals  Create a prototype mobile application to streamline the Utility Vegetation Management field survey process by improving:  Consistency in quantifying vegetation  Record keeping and customer related notes  Documentation of performed work

4 Utility Vegetation Management (VM)  One of the most expensive maintenance activities in the electric utility business  Necessary for safety and reliability  Requires a dedicated program with a good planning strategy  Requires detailed records to track spatial characteristics over time (species, volume and location)

5 Vegetation Impacts on Distribution Lines  Direct contact  Overhanging Branches  Underbrush that prevents access

6 Direct Contact

7 Overhanging Branches

8 Underbrush

9 Distribution Electric Systems  Vegetation can cause faults that are transient or constant  High current faults can trigger system protection devices ( fuses, reclosers, etc)  Faults result in outages, blinking lights, voltage anomalies, and line loss  Faults also cause customer dissatisfaction, economic disturbance, and regulatory issues  Proper vegetation management minimizes faults from trees and animals and reduces customer and regulatory issues

10 Spoon River Electric Cooperative  Operates Vegetation Management program for three rural electric cooperatives in central Illinois  15 Vegetation Management employees split into two operation units  Use Esri GIS and handheld GPS to track and document the vegetation management program. This process involves several manual steps to get from the field to the database  Model uses linear referencing and route event table to describe the work

11 Spoon River Electric: Current Processes Planning process  Collect GPS points of locations where vegetation management is needed  Make handwritten notes about equipment, access, steepness, percent canopy, and special notes  Transcribe all handwritten notes into the GIS database  Print maps for the crews  Record keeping process  Collect GPS record of location  Indicate point number and work performed on written worksheet  Transcribe the work notes into the GIS database to mark the work that is completed  Calculate work footage for the board of directors report

14 Field Map

15 Prototype Design

16  Design a survey for the cooperative managers in the Illinois electric cooperatives  Establish the current methods used at cooperatives in Illinois to budget, plan and complete vegetation management activities  Identify technology tools that are used for planning and documenting these activities  Identify the primary person responsible for managing these activities at each cooperative  Evaluate Commercial-off-the-shelf (COTS) solutions  Consider options for the server implementation  Cloud  In-house behind a firewall

17 Prototype Design  Create a paper prototype to identify a user friendly form for data entry  Evaluate this with current Spoon River employees

18 Prototype Design  Electronic prototype requirements:  Mobile by tablet or smart phone  Capable of disconnected editing  Capable of synchronizing with the distributed database when reconnected  Easy to use for employees in the field

19 Primary Information Products  Maps for communicating the work type and location to the field crews  Records showing daily progress and long term maintenance history  Estimates for work-units describing each substation or circuit

20 Product 1  This product should answer a job foreman’s question:  Where are the trees and what equipment will I need to clear them?

21 Product 2  This product should answer a line clearance manager’s questions:  Is the work completed?  When was it completed?  Were there any problems or concerns from the members that need to be documented?

22 Product 3  This product should answer a CEO or board of directors’ questions:  How long should this take?  How much will it cost?  How did we perform against our budget for this work?

23 Capstone Timeline  The timeline for this prototype/design phase is approximately six months.  Month seven will be dedicated to the conclusion of the design approach and preparing to share my results at Esri UC in San Diego.  I hope to have a working prototype to show for the conference.
