Debate flares
over health of power grid

Oct. 9--The energy fallout in the wake of Hurricane Rita has thrown a
harsh light on one of the power industry's biggest problems --
transmission.
No one knows that better, perhaps, than some East Texas customers of
New Orleans-based Entergy.
Two weeks after the storm, some 58,000 of its residential and
business customers were still without power as the weekend began, thanks
to lines that were ripped down and transformers and substations that
were knocked out.
True, Entergy took two hard hits this hurricane season, first with
Katrina and then with Rita. The company even had to scramble to move its
swamped corporate headquarters to Jackson, Miss.
But industry critics say if Entergy had invested more in its
transmission system, some customers on the fringes of the storm might
not have faced rolling blackouts and extended power outages.
Pat Wood III, who chaired the Federal Energy Regulatory Commission
until this summer, said setting aside the legitimate storm damage -- and
there is a lot of it -- Entergy's grid was already weak and chronically
underfunded.
"Honestly, the fix for this is a more robust grid. Entergy has not
invested in transmission as I think it should. It's a standing issue I
had as a regulator and still have with this company," Wood said.
Entergy's vice president of transmission, John Zemanek, is adamant
the company has not ignored transmission and said Wood is using the
post-hurricane power problems "to pursue another agenda."
Entergy has put nearly $2 billion into expanding and maintaining its
system since 1999, according to Zemanek.
"It is counterintuitive to suggest that putting additional
transmission facilities in the hurricane's path would have somehow
improved the situation," he said. "It would have just resulted in more
lines on the ground and the need for an even more extensive restoration
effort."
Wood said the issue of bulking up goes way beyond Entergy's network.
The entire nation's power grid -- which is really a cobbled- together
patchwork of systems -- is Balkanized and full of bottlenecks. Despite
soaring demand for power, investment in the poles and wires that zip
electrons around to end-users has been anemic for years.
The Edison Electric Institute reports industrywide investment in
transmission dropped $115 million per year for more than two decades,
plummeting from $5 billion in 1975 to $2 billion in 2000. Some industry
estimates say it will take between $50 billion and $100 billion to bring
the grid up to snuff.
For years, energy companies said they couldn't build new high-
voltage transmission lines in part because environmental groups and
neighborhood activists stymied their efforts. If any company was using
that as an excuse to avoid investing in transmission, that crutch is now
gone.
In the energy legislation President Bush signed into law Aug. 8,
federal regulators were given sweeping powers to blast through virtually
any barrier to building new lines.
Ken Hurwitz, a partner in the Washington, D.C., office of law firm
Haynes and Boone, said FERC now has the authority to license new
pathways for transmission lines when a state fails to issue a permit
within a year of a company's request for one.
If the state considers a request and says no, companies can appeal to
FERC for its own evaluations, including environmental assessments. And
if a state puts too many conditions on a project, FERC can also step in
with overriding power and take on the case.
FERC even has the power of eminent domain to take property to make
way for new high-voltage pathways. There are proponents of states'
rights who object to this grant of federal power over local control.
Yet Hurwitz thinks the new law will be a shot in the arm for the
national grid.
"The FERC backstop really does remove major obstacles to transmission
line construction," he said.
While investment in transmission has suffered for years, money has
poured into power generation to meet demand.
Power plants that can generate hundreds of gigawatts of electricity
were built nationwide, but the load was left to be shipped across a
jumble of largely antiquated networks.
Wood said transmission costs only amount to 8 percent of the average
electricity bill, so there should be room for companies to reposition
capital.
Entergy began to overhaul its transmission system in Texas after grid
reliability problems prompted a massive investigation by the Texas
Public Utility Commission in the late 1990s that yielded a laundry list
of problems and close to $10 million in fines.
Entergy tapped Joe Domino to spearhead the Lone Star revamp. Wood
calls Domino a good choice.
"I do think there's hope," Wood said, adding: "This guy can't do it
alone."
Domino, CEO of Entergy Texas, said Entergy has invested $100 million
in two major lines in the last two years. They run from just outside
Beaumont to The Woodlands and from the Conroe area to north Houston.
Domino stresses that thousands of linemen are working feverishly to
fix the system, but said there is simply no way around the fact that the
storm mangled Entergy's assets.
"As we go along, we're discovering problems that were not in our
original estimates," he said. "It will be many, many weeks until we get
all of our transmission lines up and running."
According to Entergy's annual report, $170 million more is earmarked
for transmission in southwest Louisiana and East Texas between 2005 and
2007.
Across the nation, Hurwitz said there has been a slight uptick in
investment since the summer of 2003, when much of the Northeast,
including New York City, was blacked out one hot August afternoon.
That cascading power outage rippled across eight states and left 50
million people in the dark, and it all started when a sagging
high-voltage power line touched an untrimmed tree in Ohio and tripped
off. The resulting grid imbalances overloaded alternate lines and shut
down power plants around the region.
Most Texas customers are isolated from compounding power outages of
that sort.
That's because the Electric Reliability Council of Texas -- or ERCOT
-- which oversees 85 percent of the state's power demand, is an island
unto itself.
ERCOT actively manages the overall flow of electrons in its Texas
region to ensure uninterrupted access. But there is no such meaningful
interconnectivity in Texas for Entergy customers.
ERCOT only operates inside the state's borders, avoiding the flow of
electricity across state lines. By doing so, it avoids interstate
commerce and federal regulatory oversight. Entergy cannot be part of the
ERCOT system because its grid is connected to Louisiana, Arkansas and
Mississippi, although the company said it is investigating how it could
restructure to come under ERCOT jurisdiction in Texas.
Michelle Michot Foss, head of the Center for Energy Economics at the
University of Texas, said the ERCOT power island probably saved some
Houstonians from losing electricity in rolling blackouts that otherwise
could have spread from Entergy's territory. But the setup also kept
CenterPoint's Texas transmission system from propping up Entergy's grid
in any meaningful way.
In theory, if Entergy were hooked into ERCOT and electricity could
have flowed from the west, which was out of the hurricane's reach, some
of the blackouts and power outages in places like The Woodlands,
Cleveland and Jasper might have been prevented.
Even though CenterPoint, which is a part of ERCOT, and Entergy, which
is a part of the Southeastern Electric Reliability Council, border each
other, the two companies grew up as two completely different power
grids.
The old Gulf States Utilities, which was acquired by Entergy in 1992,
provided power to parts of southeast Texas and southwestern Louisiana.
It ran on a completely separate system from the old HL&P lines, now
owned by CenterPoint.
"They're just too different. You can't say throw me a cord so we can
stay on," Wood said.
