Wildfire Mitigation Plan December 2, 2019

California’s Wildfire Risk

1

Year-Round Fire Season: Changes to California’s climate means that the traditional notion

• f a fire “season” no longer exists

Hazardous fuel is building up: 10M acres of land contain ready-to-burn kindling from nearly 147M trees that have been killed or weakened by drought and bark beetle infestation

Local Community High Fire Risk Area Map

What makes up SCE’s HFRA? A combination of historical map boundaries (based on past fire management and response experiences), CAL FIRE’s Fire Hazard Severity Zone (FHSZ) maps, and most recently the CPUC High Fire Threat District map are used to inform SCE’s High Fire Risk Areas.

CPUC Tier 3 = ~18% CPUC Tier 2 = ~9% Other HFRA = ~8%

Approximately 1/3 of SCE’s 50,000 square mile service area is located in HFRA.

* Areas within SCE’s service area that continue to be designated as HFRA and are in the process of being evaluated to determine whether they remain as HFRA

Scope of SCE’s 2019 SB 901 Wildfire Mitigation Plan

3 OPERATIONAL Inspections

• Enhanced overhead inspections (EOI) on transmission and distribution structures in

HFRA

• Various existing inspections (poles, switches, circuits, relays, etc.)
• Infrared, Corona scanning and high definition (HD) imagery

Public Safety Power Shutoff (PSPS)

• Effective communications and engagement with emergency services, customers and

communities

Situational Awareness

• Weather stations and HD cameras

Vegetation Management

• Hazard tree removal (trees beyond traditional trim zone)
• Vegetation removal at poles
• LiDAR surveying for transmission, supplemental inspections in HFRA
• SCE plans to implement a 12-ft tree clearances from distribution power lines

in high fire areas to ensure annual growth will not encroach on compliance distances.

INFRASTRUCTURE Covered Conductor

• Circuit miles of covered conductor in HFRA

Undergrounding

• Evaluation of certain distribution lines in HFRA for potential undergrounding.

Other Infrastructure Mitigations

• Various system hardening activities (e.g., composite poles, current limiting fuses (CLFs),

remote automatic reclosers (RARs), Fast Curve settings)

• Studies, evaluations and pilots of alternative technologies

Infrastructure - System Hardening Elements

Covered Conductor Reclosers Fast-Acting, Current Limiting Fuses (CLF)

Enhanced Overhead Inspections (EOI)

Enhanced Overhead Inspections Identify Potential Risks

• In less than 5 months, our crews

completed detailed ground- based inspections of 400,000+ distribution and transmission structures in HFRA

• Deploying helicopters and drones

equipped with Infrared, Ultraviolet, LiDAR and HD image scanning to perform aerial inspections of our facilities in HFRA

5

SCE’s helicopters are equipped with software and high-tech cameras, like the one shown above, to find potential risk undetectable to the human eye

Situational Awareness Capabilities

Situational Awareness Center

• SCE meteorologists
• 24/7 monitoring

Fire Monitoring Cameras

• High-Definition
• Remote-controlled

Advanced Weather Modeling

• Better Forecasting
• Advanced Warning

Weather Stations

• Hi-Res Data
• Local Weather

Public Safety Power Shutoff (PSPS)

7

▪ De-energization to prevent ignitions from powerlines ▪ Used during extreme fire conditions ▪ Primarily impacts circuits in high fire risk areas ▪ Other circuits in non-high fire risk areas may be impacted if

transmission lines are de-energized

▪ Red Flag Warning does not mean a PSPS will be called ▪ Actual frequency of PSPS events will depend on various weather and

environmental factors​

▪ Decision will be made with most accurate assessment of real-

time information and situational awareness data

PSPS Decision Points

8

Decision points include but are not limited to:

• SCE Meteorologists

forecast strong wind conditions in service territory

• SCE Fire Scientist

assessment of fire potential to include consideration of weather and fuels

• Impact of

de-energizing circuits on first responders and essential services

• Real-time
• bservations

from qualified personnel monitoring for hazardous conditions in the field

* Erratic or sudden onset of conditions may prevent the input from real-time observations or consultation with first responders

Typical Solar Situation: (Net Energy Metering) You export solar to the grid when you don’t need it and get a monetary credit for each kWh that is sent to the grid.

What is Load Shifting?

Graphic from Energy Storage News You will charge your battery with your solar system during the day and then use some of that energy in the evening instead of buying the most expensive energy from the grid WITHOUT LOAD SHIFTING WITH LOAD SHIFTING

WHY ENERGY STORAGE?

By going solar, you are taking the first step towards energy

• independence. However, with

a traditional system, the grid must be present to have power. By utilizing battery storage technology, you can bank the energy you produce for times when you need it most.

How does it work?

Energy Storage Fundamentals

• kW = Power
• kWh = Energy

kWh = how long will my battery last? kW = how many household loads can I run at a time?

• Solar PV systems typically sold by kW
• Energy storage systems typically sold by kWh
• kWh is what we are charged for on our monthly electric bill

AC vs. DC Coupled

AC Coupled

• Flexibility
• Great for existing PV systems
• Slightly lower efficiency than DC coupled

systems DC Coupled

• Simplicity => 1 inverter
• Great for new PV systems
• Slightly higher efficiency than AC coupled

Can I backup my whole home?

MAYBE

• Budget
• Home size
• Home location
• What do I really need

during an outage?

20% DoD

90% DoD

• Many factors influence the degradation rate including
• Charge/Discharge rate
• Temperature
• DoD
• Cycles per day (Throughput)

Key Points:

• DoD affects

degradation rate

• Lithium ion

batteries can handle full discharge much better than lead acid

• Refer to

manufacturer warranty for best design practices

In Incentives

Apri ril Pri rice Community Environmental Council

Federal Tax Credits

Investment Tax Credit (ITC) Your solar-tied battery system will be eligible for the ITC as long as it is charged by solar. Tax Credit: System installed in 2019= 30% System installed in 2020= 26% System installed in 2021= 22% System installed in 2022= 10%

Self Generation In Incentive Program

FOR LOAD SHIFTING BATTERIES TIED TO SOLAR: Incentive has been available at a price/watt hour. Most recent incentive was a one-time payment of 25 cents/watt hour So, for a 13.5 kWh battery, a $2,900 Incentive was recently available. Incentive levels decrease as more people subscribe. So, if the level is decreased- incentive COULD be: 20 cents/watt hour ($2,320 for same battery)

Self Generation In Incentive Program

Available~ April, 2020 Enhanced Incentives Enhanced Incentives

~April, 2020 Eligible customers are those in high fire threat districts, and are also:

• Low-income or living in a

disadvantaged community

• “Medical baseline” consumers or

consumers who have notified utilities that they have a serious illness or condition that could be life-threatening without electricity

standalone storage) will participate in events that allow CPA to call on their battery as a distributed resource

• On event days customers charge battery with solar during low price periods

in the middle of the day, and battery is discharged during evening peak (4pm-9pm)

• Enrollment incentive of $100 for residential and $250 for commercial ($125

and $300 for DAC)

• Annual incentive of $100/kW for participation in load shifting events based
• n committed capacity ($125/kW for DAC)
