Deployment Design
Fully deploy across service area
Substation by substation
Address poor reliability substations first
Address substations with high customer counts
Maximize benefits
Low reliability circuits
Break circuits into quarters
Automate multiple open ties
Other circuits
Split circuit in halves
Automate one open tie
Share open devices between circuits

3. Deployment Implementation
11/23/2018
Deployment Implementation
Approximately 100 / year
Distribution develop plans
Where plan deployment corresponds to reliability issues
Worst performing substation
Individual circuit performance
Reliability calculated over multiple year performance
Utilize existing automation as possible

4. 10% - 300% root cause analysis Failure of existing devices

Outside of Deployment
10% - 300% root cause analysis
Failure of existing devices
On Going automation reviews
Review distribution development plans for automation needs
Recommend circuit reconfiguration to maximize automation effectiveness
Install new automation to restore lost functionality due to switching
