Four Entities Team Up on Transmission
Aug 14, 2007 - BUSINESS WIRE
With the common goal of bringing new
transmission to the Rocky Mountain and Desert Southwest
regions, Arizona Public Service Company, PacifiCorp,
National Grid and the Wyoming Infrastructure Authority
today announced they have entered into an agreement
to work together on preliminary development of new
high-voltage transmission lines for the West.
The agreement builds on PacifiCorp's
May 30, 2007 announcement the company would construct,
by 2014, more than 1,200 miles of new 500-kilovolt
transmission lines necessary to address the long-term,
growing energy needs of the six states it serves
and to access planned renewable energy resources.
One segment of that proposed transmission project,
a southern route line, from eastern Wyoming into
Utah and on to the Desert Southwest, has aspects
in common with a project proposed in October 2005
At that time, APS announced plans
to explore the TransWest Express Project's (TWE)
feasibility of building electric transmission lines
from Wyoming to Arizona to meet its customers' long-term
growth needs. In March 2006, APS signed a memorandum
of understanding with the WIA and National Grid
to collaborate on this study. In December 2006,
APS completed a feasibility report that concluded
that TWE potentially creates significant benefits
for its customers. APS and other interested parties
have been pursuing the next phase of developing
the TWE project.
In the interim agreement announced
today, the four parties agree to work together on
initial activities during the next six months to
co-develop these projects, with a decision on next
steps to be made in 2008.
By working together on new transmission
infrastructure, the parties believe there may be
substantial advantages for the region, including:
the ability to meet growing demand
improved overall electric reliability
for the West,
improved access for renewable energy
better use of transmission corridors,
opportunities to coordinate permitting
economies of scale and cost savings
in development and construction activities.
National Grid will act as the lead
developer with support from APS, PacifiCorp and
APS, Arizona's largest and longest-serving
electricity utility, serves more than 1 million
customers in 11 of the state's 15 counties. Arizona
is the fastest growing state in the country and
Phoenix is the nation's fifth largest city. The
rapid growth has resulted in energy demand increase
of more than 4 percent each year by APS customers.
With headquarters in Phoenix, APS is the largest
subsidiary of Pinnacle West Capital Corp. (NYSE:
PacifiCorp is one of the lowest-cost
electricity producers in the U.S., providing approximately
1.7 million customers with reliable, efficient energy.
PacifiCorp operates as Pacific Power in Oregon,
Washington and California, and as Rocky Mountain
Power in Utah, Wyoming and Idaho. PacifiCorp has
more than 9,062 megawatts of generation from coal,
hydro, gas-fired combustion turbines and renewable
wind and geothermal power. Visit www.pacificorp.com.
Formed in 2004 by the State of Wyoming,
the WIA's mission is to diversify and expand the
state's economy through improvements in electric
transmission infrastructure to facilitate the consumption
of Wyoming energy. Wyoming has abundant resources
for generating power to serve the growing needs
of the region, including high-quality wind energy
National Grid plc is an international
energy delivery business with principal activities
in the regulated electricity and natural gas industries.
It brings proven experience in the U.S. and internationally
in building and operating complex transmission infrastructure.
