Duke Energy harnesses winds of the West
Apr 16 - McClatchy-Tribune Regional News - Bruce Henderson The Charlotte
Observer, N.C.
As Duke Energy works to meet North Carolina's recent mandate to produce
renewable energy, an unregulated division is whipping up wind power in
Wyoming and Texas.
Duke Energy Generation Services develops, owns and operates power plants for
large users such as utilities, municipalities and industries in 18 states.
More recently, it has focused on harnessing the winds of the West.
Two years after its first wind acquisition, Duke operates 500 megawatts. Its
customers include Wal-Mart's Texas operations. It's developing up to 5,000
megawatts more -- the capacity of more than four of Duke's nuclear reactors
-- in a dozen states.
Duke's home state, meanwhile, awaits its first commercial wind farm.
That's just one conundrum of renewable energy: Drawing power from the wind,
sun, waves or organic wastes means going to the resource. While the N.C.
coast and mountains show some promise, neither can match the wind belt
stretching from Texas to the Dakotas.
The energy potential out West is so strong that Duke has invested $1 billion
in western wind projects, and hopes to grow that investment to $3 billion by
2013.
"The real growth," said Generation Services president Wouter van Kempen, "is
in renewables."
Duke has its eye on another renewable fuel that North Carolina has in
abundance -- the farm and forest wastes called biomass. Last year Duke and
Areva, a multinational company best known for nuclear power, launched a
joint biopower venture called Adage.
But wind dominates the decor outside van Kempen's 31st-floor Charlotte
office, from a head-tall model turbine to the flat panels that track the
operating status of Duke's wind portfolio. Walls are being rebuilt for a
control center where technicians will monitor wind data around the clock.
Wind power accounted for 42 percent of the nation's new electric generation
in 2008, the American Wind Energy Association says.
"The primary reason is that we have renewable-energy portfolio standards in
(28) states," said Revis James, who does energy economics analyses for the
Electric Power Research Institute. "Combine that with, so far, a consistent
renewal of (federal) subsidies, and it's attractive."
By requiring utilities to sell power made from renewable sources, portfolio
standards create new markets for those energy sectors. Federal tax credits
and favorable depreciation rules also help.
If Congress sets the nation's first limits on carbon dioxide emissions,
James added, wind assets will look even better compared to fossil-fueled
plants that produce the greenhouse gas.
Tough obstacles stand in the way of expanding the sector. The biggest of
those: a lack of transmission lines to connect the often-remote places where
the wind blows hardest to energy-hungry cities.
And some people won't like the idea of turbines towering 275 feet high amid
scenic views -- just ask the wealthy folks of Cape Cod, Mass., who have
fought hard against a proposed wind farm.
"They're not the old eggbeaters some people think they are," the
Netherlands-born van Kempen said of the sleek designs. "We think they're
beautiful."
