SCE Strategy for a Clean Energy
Future
• SCE is doing its part to reduce greenhouse
gas emissions by providing its customers
with energy from renewable resources
• Smart power delivery is needed to manage
greater diversity of supply and to optimize
existing capacity
• Smart metering enables customers to increase
energy conservation and reduce peaks while
improving customer service and operational
efficiency
• Plug-in electric vehicles will achieve
transportation sustainability and enable
distributed energy storage systems
Innovation in Energy Technology will Deliver
Environmental Benefits & Customer Value

SCE Energy Efficiency
In five years, SCE's energy-efficiency
programs have saved enough energy to
power 789,000 homes for an entire year
&
reduced greenhouse gas emissions equal to
removing 400,000 cars from the road
Over the next three years SCE is proposing to
invest more than $1.3 billion to achieve savings
in excess of 3.5 billion kilowatt-hours.

Carbon Policy Driving SCE Renewables Integration
CA Renewable Portfolio Standard
• 20% by 2010
• Possibly 33% by 2020 (statute under consideration)
California Solar Initiative (CSI)
• Goal of install 3,000 megawatts (MW) of new, customer-side solar photovoltaic projects by 2017. The CPUC provides incentives for all solar installations in existing structures.
CA Carbon Reduction Law (AB32)
• Reduce GHG by 25% by 2025
Renewable Portfolio 2007
California law and policy is driving need for a smarter grid

So what makes a grid smart?
• A smart grid involves adding millions of smart electronic devices,
like phasor measurement units, fault indicators, meters and chargers
in electric cars to the grid that will send and receive millions of
pieces of data per minute to produce actionable information and
using that information to control the electric system.
• By adding this more sophisticated intelligence and control, the Smart
Grid will allow:
– Higher transmission transfer capacity
– Integration of more intermittent renewable generation
– More efficient and effective maintenance practices
– Faster restoration when outages are unavoidable
– More customer choice and energy determination

Renewables Integration
• Provide real-time voltage support to mitigate volatility associated with intermittent renewable energy resources
• Increase transmission capacity to integrate more bulk renewable energy resources
• Integrate large scale energy storage systems as a parallel power source for Voltage/VAR/frequency support with bulk intermittent renewable energy supply
SCE leads the nation in renewable power delivery,
procuring about 13 billion kilowatt-hours per year

Synchronized Phasor Measurement
System
• The growing complexity of interconnected electric grids increases the threat of blackouts and other operational challenges, facilitating the need for a smarter electric grid equipped with wide-area measurement units to monitor large grids
• Phasor measurement units (PMUs) help identify remote system disturbances in advance to prevent wide-scale power outages
• Power System Outlook (PSO) is a real-time tool that enables operators and engineers to quickly and affordably analyze synchro phasor measurement system data from a large power grid
Phasor technology enables real-time system monitoring
and reduces the probability of major disturbances

Benefits of electric Transportation
• New ET load off- peak with appropriate rates, control
technology & DR programs will help improve the electric
system efficiency by spreading fixed energy costs over more
energy use.
• System stability may be enhanced through communications
and control technologies “shaping” ET load to renewables
integration needs. In addition, “storage capabilities” from both
the vehicle and stationary applications will enhance
renewables dispatchability.
• Storage presents significant potential as utilities comply with
future RPS requirements. Effective “control” of bi-directional
energy flow (solar and mobile/stationary battery storage)
presents significant challenges in the near term from an
infrastructure and IT perspective.
