OG&E Selects GE Energy and Silver Spring Networks for Smart Grid Program

OKLAHOMA CITY, Oct. 29 /PRNewswire-FirstCall/ -- OG&E announced today it has
entered into agreements with General Electric Energy (GE) and Silver Spring
Networks to handle key aspects of its Positive Energy®( )Smart Grid Program to
begin with full deployment in Norman, Okla. next year.

The program is the next step in OG&E's initiative to use smart grid technology
to provide customers with more information to help manage their energy use and
save money, without compromising their lifestyles. It also will help OG&E
maintain reasonable electricity rates and continue highly reliable delivery of
electricity to its customers.

GE will provide the 42,000 smart meters in Norman, Okla. The digital devices
will measure electricity use in the home or business and transmit the
information to OG&E for billing and service monitoring. The information will
be communicated via Silver Spring Networks' Smart Energy Network, a secure,
IP-based network. In the summer of 2008, OG&E began working with GE and Silver
Spring Networks for its pilot study of smart grid technology with 6,600
customers in Oklahoma City. (Information about the Oklahoma City study and
interviews with customers are available on the home page of
www.itsyoursmartgrid.com by clicking on the video entitled "Oklahoma Gas &
Electric".)

"Smart grid technology is important for our customers, for our employees and
for our shareholders," said Ken Grant, managing director of OG&E's smart grid
program. "After more than a century of serving our customers, it is important
that we partner with companies who have successful track records with this new
technology."

As part of the Norman deployment, 2-3,000 customers will be recruited to
receive information in almost real time regarding the price of electricity by
time of day and the amount being used. The study will measure how many of
those customers use price information to alter their energy consumption
patterns and to lower their electric bills.

With the complete information network and smart meters in place, OG&E will be
able to remotely connect or disconnect service to homes or businesses and
receive notifications as soon as power outages occur, reducing response time
to restore service.

According to Grant, in the next few weeks OG&E will select the company to
install the smart meters and the companies to coordinate with OG&E on customer
support and installation of devices in homes or businesses participating in
the Norman study.

"We want to make sure that this technology works well before we integrate it
completely into our normal operations and employee processes," said Grant.
"However, we're confident smart grid technology is the future for our
industry. We're looking ahead with many of our employees involved in
designing the processes for use in Norman and later across our service
territory for all of our customers."

OG&E received notice on Oct. 27 that its application for $130 million in smart
grid stimulus funds has been approved, pending negotiations with the
Department of Energy in November. The company will seek state regulatory
approval for recovery of the remaining costs of the almost $300 million
deployment across its entire service territory over the next three-five years.

service area spanning 30,000 square miles in Oklahoma and western Arkansas.
