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.

4

SCE’s integrated solution

Clean the power grid. And electrify.

5

Role of the UtilitySCE’s vision: Enable the plug and play grid to enhance system reliability, support customer choice and use of clean energy technologies, to help California meet its clean energy goals.

Strengthen and Modernize the Grid

Modernize Distribution Planning

Influence Regulatory Outcomes that Benefit

Customers

Establish appropriate compensation for DERs

based on the value at the time and location of the

services they deliver

Integrate DERs in grid planning through more

transparent, multi-stakeholder processes,

tools, and analysis

Improve safety and reliability, and increased DER

integration
