Southern California Edison in 2018
• 15 million residents in a 50,000 square mile area• 40% energy from carbon‐free sources• Joined open letter to support Paris Climate Accord• Utility Dive “2017 Utility of the Year” for our 2017 Clean Power and Electrification Vision Plan
• Procured close to 500 MW of storage
Supporting California’s 2030 greenhouse gas reduction goals
2
Goals To Improve
• California set a goal to reduce emissions 40% below 1990 levels by 2030, and 80% by 2050.
• SB 100 passed mandating 100% carbon free electric grid by 2045
If we want to get to zero emissions, eventually we have to replace many of the things we rely on today that require combustion.
3
Emissions contributors
• The largest contributor is transportation, followed by the electric sector.
Industrial, and commercial and residential sectors trail not too far behind.
• The most practical andeconomicalway to create real change is for sectors to work together to find an affordable alternative to fossil fuels.
