SDG&E Transmission System Overview SDG&E Owned Palomar 566 MW SONGS no longer in- IPP Owned service (was 2150 MW, 20% Owned by SDG&E) IV renewables Otay Mesa 900 MW 603 MW • Service Area – 4,100 square miles • 1,951 Circuit Miles of Transmission • 1.4 million Electric Meters • 24 Transmission Substations • Total Local Generation 3090MW • 109 Transmission/Distribution Substations • Maximum Import Limits 3350MW 8 Identifying Risk: Increased Wildfire Activity The map below shows portions of San Diego County that have burned since 2000, including the Cedar Fire and all major 2007 fires. 2003 (Cedar Fire) • Acres Burned: 280,278 • Structures Destroyed: 2,820 • Structures Damaged: 63 • Vehicles Destroyed: 148 • Deaths: 14 • Injuries: 104 2007 (All Major Fires) • Acres Burned: 368,566 • Structures Destroyed: 2,665 • Structures Damaged: 117 • Vehicles Destroyed: 239 • Deaths: 7 • Injuries: 127 (For the purposes of this slide/presentation, structures refer to overhead utility structures) 9 Understanding Risk: Drought Enhancing 2014 Wildfire Potential • Rainfall over the last year has been 25%-50% of normal. • This is our third consecutive year of below normal rainfall. Rainfall Normal Location Percent of Normal CA Drought Monitor (thru Apr 14) (thru Apr 14) Laguna Beach 3.88” 13.81” 28% of Normal • 100% of CA in Severe Drought Oceanside 4.20” 13.58” 31% of Normal • 76% of CA in Extreme Drought (Including much of San Diego County) Lindbergh Field 5.06” 10.31” 49% of Normal Ramona 7.85” 16.00” 49% of Normal Campo 6.95” 15.66” 44% of Normal Early Season Wildfire Activity • May 13-16 Fire Complex • Coastal San Diego County • 8 wildfires were greater than 100 acres • Over 13,000 customers affected • Over 40 homes destroyed • One Fatality • Estimated $60 Million Damage • 26,000 Total acres 10 Risk Mitigation: Establishing Resilience to Wildfire Wood to Steel (2,220T & 1,750D) Meteorologists and Fire Coordinators Mobile Command Centers Air Support Contract Contracted Fire Fighters Mobile Fire Trailers Updated Operational Procedures 11 Risk Mitigation: Proactive Operational and Developmental Measures • Operational changes to turn-off reclosing • Mobilizing crews to pre-determined locations • De-energize for safety when necessary • Staging of washing rigs and fire crews to pre- determined locations • Prior to and throughout the event, SDG&E provides situational awareness and forecasts to CAISO • Coordinate with neighboring utilities for potential support • Take operational actions as needed to optimize power flows in coordination with the CAISO. • For major events, the CAISO will declare a system emergency where they may suspend code of conduct and allow out of market sales to stabilize system 12 Building Resilience: Situational Awareness Enhancements through Community Collaborations and Big Data • SDG&E Weather Station Network: largest • State-of-the-Art Forecasting System: Provides superior utility weather network in the world delivering understanding of weather and vegetation moisture unsurpassed real-time decision support supporting proactive emergency operations • Mountain top camera network allows for real • Collaborations with key stakeholders in the time monitoring of hazardous conditions local fire community increasing data sharing providing updated intelligence • Click here to play video 13 Building Resilience: Developing Operational Tools Fire Potential Index (FPI) The Fire Potential Index is a planning and decision support tool designed to reduce the risk of a wildfire while improving efficiency and reliability • Incorporates weather, live fuel moisture, dead fuel moisture, and greenness of the annual grasses. • Calculated for 8 sub-sets of the SDG&E Service Territory • Used to inform operational decisions, work restrictions, resource allocation 14 Building Resilience: Developing Operational Tools Fire Potential Index (FPI) Border Fire Pines Fire Witch Fire Cedar Fire Sierra Fire Angel Fire 18 17 16 15 14 13 12 11 10 9 8 7 FPI 6 5 4 3 2 1 Privileged & Confidential, Prepared at the Direction of Counsel Slide 15 15 Building Resilience: Developing Operational Tools Santa Ana Wildfire Threat Index (SAWTI) Our Mission: Develop a tool to mitigate risks associated with extreme fire potential during Santa Ana Winds. Our Vision: To provide a decision support tool to fire agencies and the general public to increase public safety and overall preparedness. 16 Building Resilience: Vegetation Management Program • SDG&E Vegetation Management maintains a comprehensive database of over 455,000 trees that could impact our system. • Includes tree location, species, growth rates and pruning history • This program has resulted in drastic decreases in tree- related outages on the system. 17 Lessons Learned Comprehensive Program to Reduce Fire Risk and Improve Mitigation: – Extensive engineering changes (more stringent design criteria, use of fire-resistant materials, use of state-of- the-art equipment) – Expanded QA/QC inspection and repair program – Escalating operational changes coincident with conditions – Weather monitoring and forecasting – Aggressive vegetation management program – Far reaching community outreach and involvement 18 Creating Wildfire Resilience through Preparedness Thank You Questions?
