Resilient Grid
Two-part system resiliency proposal:
Underground Electrical Safety and Resiliency Program - Supports inspections
and reinforcement of the underground distribution system. Includes:
–
Manhole inspections
–
Damage and voltage-indication testing for underground infrastructure
–
Monitoring and tracking systems
Overhead Reliability and Resiliency Program - Upgrade and replace the
overhead utility poles and associated infrastructure
–
Pole inspections and replacements
–
Double-pole transfers and removals
–
Vegetation-related resiliency initiatives
A resilient grid is a prerequisite to support grid modernization.

Smart and Integrated Grid Smart and Integrated Grid plan focuses on 10 different investment programs. Investment Program Description 1. Advanced Sensing Technology Substation to line and urban network SCADA Grid-Wide Situational Awareness 2. Next Generation Remote Fault Indication Detection of overhead and underground faults 3. Distribution Management System IT system to enable real time grid reconfiguration Advanced Analytics 4. Network Load Flow Model of power flows on urban networks 5. Predictive Outage Detection Data analysis to identify potential faults 6. Automated Feeder Reconfiguration Real Time Flexible Grid Action Fault isolation and restoration (OH, UG) 7. Volt VAR Optimization Voltage regulation to minimize system losses 8. Integrated Planning and Tracking for DER Advanced load flow modeling and DER tracking Dynamic DER Integration 9. Energy Storage Substation storage to manage DER intermittency 10. Adaptive Protection/Two-way Power Protection technology to increase DER penetration

Overall Summary Short-Term Investment Plan (STIP) request represents $431 million over a period of five years. Smart & Integrated Grid - $172M Resilient Grid $150M Customer Engagement $108M Grid-Wide Situational Awareness Real Time Flexible Grid Action Advanced Analytics Dynamic DER Integration Advanced Sensing Technology Distribution Management System Automated Feeder Reconfiguration Integrated Tracking and Planning for DER Underground Safety and Resiliency Opt-in TVR (Systems and Metering) Next Generation Remote Fault Indication Network Load Flow Volt VAR Optimization Overhead Safety and Resiliency Energy Storage Predictive Outage Detection Adaptive Protection /Two Way Power Flow Enabling Investments - $66M Customer Education Communications Cyber-Security Total = $496 million, less baseline capital of $65 million, for an incremental request of $431 million.
Key Benefits Core Investment Plan will provide the following benefits: Improved reliability and reduced restoration times; Improved customer service; Reduced end-user consumption and line losses; Reduced peak demand; Improved asset management and workforce utilization; Reduced costs to integrate DER; and Support for emerging technologies and energy policies Our plan results in a more satisfied, educated and engaged customer to positively interact with a modern grid.
