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.
