Service Territory

Great River Energy

Transmission

• Operator logging

• Clearances

• Events & outages

• Overtime call-outs

Generation

• Operator logging

• Generation outages / derates / tests

• Shift-change checklists

Process Areas

Where We Were…

• Disconnected logging

• No ties to Maximo

• Unfinished functionality

• Expensive solution

• Use Maximo (HSE) and EAM

• Prototype functionality / agile approach

• Cloned applications

• Cognos reports

Decision & Approach

Solution should support use of a single screen for logging and all related functions

Guiding Principle

Transmission Event Logging

Line Outages

Substation Outages

Relay Operations

Indented Log Entries / RTN

Logging Clearances

Generation Logging

Generation Shift Checklists

Transmission REPORT

• Clearances application• Generation application• Events • Outages• Supporting screens

–Log units & sites–Circuits–Shift checklists

Other screens

• Work with Interloc to streamline scripts – may result in Java classes

• Formalized testing

• Go-live by end of year

Next Steps

• Having an incomplete current state solution is a challenge

• Disconnect between leadership vision and “in-the-trenches” reality

• Uncertainty of regulatory changes

• Giving users what they (think they) want
