Results Were Not Favorable
Sold overseas assets at a loss
Gave up on telecom
Enron killed energy trading
Lots of write-offs
Net result was a return to the core utility business
Renewed focus on electric reliability and customer satisfaction
Security
And pleasing the regulators

Yeager’s 21st Century Transformation
Integrating communications to create a dynamic, interactive power system as a
new “mega-infrastructure” for real-time information and power exchange.
Automating the distribution system to meet changing consumer needs. The
value of electricity distribution system transformation—fully automated and
integrated with communication—derives from four basic functionality
advantages:
1. Reduced number and duration of consumer interruptions, system fault
anticipation, and faster restoration.
2. Increased ability to deliver varying “octane” levels of reliable, digitalgrade power.
3. Increased functional value for all consumers in terms of metering,
billing, energy management, demand-response, and security monitoring,
among others.
4. Access to selective consumer services including energy-smart
appliances, power market participation, security monitoring, and distributed
generation.

21st Century Transformation (cont.)
Transforming the meter into a consumer gateway that allows price
signals, decisions, communications, and network intelligence to flow
back and forth through the two-way energy/information portal.
Integrating distributed energy resources. The new system would also
be able to seamlessly integrate an array of locally installed, distributed
power generation (such as fuel cells and renewables) as power system
assets.

NARUC 2005 BPL Report
BPL technology holds promise for extending service
to underserved areas, facilitating broadband
competition, and enhancing both security and
reliability through a “smart grid.”
While operational enhancements have always been
of interest to the electric industry, the August 14,
2003 Northeast power blackout and its aftermath
broadened interest in the preventative measures that
might be achievable though BPL.

FCC and FERC Endorse BPL
Specifically, FERC Chairman Wood and FCC Chairman Powell believe:
that ubiquitous broadband deployment is important to the economic,
educational, social, medical, and cultural welfare of the country. In order to
achieve this goal, national policies should facilitate rapid deployment of all
broadband technologies, including BPL. Policymakers at all levels should
coordinate their efforts to promote a minimally intrusive policy framework for
such technologies.
that the provision of high-speed communications capabilities over utility poles
and electric power lines (Access BPL) provides an opportunity to increase
the competitive broadband choices that are available to customers and the
power supply system management options of utilities.
that Access BPL may help provide additional power supply system
communications and control capabilities to improve reliability and
efficiency. Such capabilities include “self-healing” network capabilities;
improved security from physical and cyber threats; facilitating use of distributed
generation; customer and utility control of appliances and equipment energy
use; improved load management and electric grid utilization

DOE’s 2004 Delivery Technologies Roadmap
“The revolution in information technologies that has transformed other
industries has yet to fully take hold in the electric power business”
“Greater use of distributed intelligence, smart controls, and distributed
energy resources, including demand response, will play an increasing role
in addressing the needs of the electric grid”
Integration to “optimize the flow of both information and electric power- in
real time, and give customers a greater opportunity for involvement in
electric markets”
“More rapid integration of distributed energy technologies and smart
systems for optimizing customer and local distribution system operations
needs to occur”
DOE's “Grid 2030-A National Vision of Electricity's Second 100 Years”
outlines the characteristics of a modernized electric grid

Advanced Metering Coming to
California; The Regulators' Vision
Advanced interval capable meters with communication
links will be installed on all customers.
Critical peak pricing will become the
default tariff for all customers. Customers
will have the option to ‘opt-out’ to realtime pricing or risk-adjusted time-of-use,
tiered, or other rate forms.
