TransÉnergie:
Playing Two Power Games
By Peter Fairley, Technology Review
On
a Thursday afternoon June (2004), state troopers from Connecticut
and New York fanned out on a manhunt. Their quarry: several of the
dozen Connecticut legislators and commissioners with the power to
make or break Massachusetts-based TransÉnergie U.S., a pioneer
in advanced high-voltage power transmission owned by Montréal
power utility Hydro-Québec. For two years, political squabbling
had idled an innovative 40-kilometer underwater power line installed
by Trans-Énergie to strengthen the link between the Connecticut
and Long Island power grids. On the Thursday in question, Trans-Énergie,
Long Island’s power utility, and Connecticut regulators had
finally found a way to end the impasse. All they needed to seal
the deal were signatures from all 12 of those Connecticut politicians.
The manhunt
marked the dramatic close to a saga that made TransÉnergie
a poster child for the confusion that reigns in the U.S. power market.
In the early 1990s, the U.S. Congress threw wholesale power markets
open to competition, enabling state utilities to buy bulk power
from generators located hundreds or thousands of kilometers away
(much of New England and New York’s power, for example, comes
from Québec). But regional coordination of power grids to
accommodate long-distance power delivery has stalled. All too often,
coordination has fallen victim to interests that stand to lose from
increased competition; and federal law gives states the upper hand
in regulating electrical transmission, thwarting the best efforts
of power regulators in Washington. "It’s really a mess,"
says Sally Hunt, a power-industry expert affiliated with National
Economic Research Associates, a consultancy in New York.
TransÉnergie’s
project got caught in a tussle between Connecticut and New York.
"We were stuck in the middle of a much larger policy debate,"
says Trans-Énergie U.S. president Jeff Donahue.
What makes the
gridlock tragic is that it’s stifling the application of advanced
transmission technologies that promise to not only facilitate power
sharing across the continent’s aging power grids but also
make them more reliable. TransÉnergie’s Cross Sound
Cable is one of the first in a string of power lines that exploit
digital switching, a technique that allows unprecedented control
over electrical flows in the network while simultaneously filtering
out dangerous spikes and sags (more on that later).
The benefits
of the Cross Sound Cable were initially lost on Connecticut politicians,
who believed that the cable would serve only to feed Long Island’s
seemingly insatiable appetite for energy at the expense of Connecticut’s
consumers and natural environment. Technical missteps by TransÉnergie
deepened its problems in Connecticut, giving state officials license
to use the company as a political whipping boy. But a very lucky
break, in which Trans-Énergie and its supporters shrewdly
exploited the -cable’s advanced technology, turned the tables.
When the August 14, 2003, blackout threw Long Island into darkness
(along with much of the northern United States and Ontario), the
Cross Sound -Cable was pressed into service to help stabilize the
grids. Ed Grilli, chief of staff for the Long Island Power Authority,
says that August 14 set the stage for a political breakthrough:
"Quite frankly, what saved us in the end was the blackout."
Six
Feet Under
The pair of
10-centimeter-thick cables begins in a building located in New Haven,
CT, connects to a set of digital power valves, travels beneath the
Long Island Sound—buried under approximately one to two meters
of muck—and comes ashore 70 kilometers east of Manhattan to
feed an identical set of valves located on the site of the deactivated
Shoreham Nuclear Power Station, which stands in eerie silence as
a symbol of the public concerns that crippled the U.S. -nuclear-power
industry. The $6 billion plant was fully built but had never operated
commercially when local opposition, led by then governor Mario Cuomo,
forced its closure in the late 1980s. The Cross Sound Cable’s
greatest enemy was an equally popular politician from across the
sound: Connecticut attorney general Richard Blumenthal. Like Eliot
Spitzer, his better-known New York counterpart, Blumenthal is both
an activist attorney general and a likely contender for the Democratic
nomination to challenge his state’s Republican governor in
2006. Grilli says that TransÉnergie handed Blumenthal a juicy
issue, and the ambitious poll made the most of it. "They got
swallowed up," says Grilli.
The Cross Sound
Cable saga began in the late 1990s. Grilli’s operation was
desperate for electricity. Demand for power on Long Island grew
larger every year, and reserve capacity was getting thin. After
summer heat waves in 1999, power supply became a high-profile issue.
The authority invited power producers to build new plants on Long
Island, but it also wanted to access the relatively cheap power
available in New England. Trans-Énergie offered a deal the
authority couldn’t refuse: it would create a subsidiary, the
Cross Sound Cable Company, that would build a line under the sound,
at its own expense. The subsidiary, coowned by Connecticut utility
United Illuminating, would then rent capacity on the line to the
authority. This would be the first such "merchant" line
in the United States, and TransÉnergie knew how to exploit
digital switching technology to make it work.
Electricity
flows over power grids at the mercy of the laws of physics. As consumption
levels shift from moment to moment, electrical energy follows the
path of least resistance from generators to users. The result is
that a power company’s grid isn’t limited to delivering
electricity to its own local customers but can also, at any moment,
become the unpaid carrier of power flowing automatically from high-supply
areas to high-demand areas outside its own region. That makes building
new power lines—which traditionally use alternating current
(AC)—a very tough sell for an independent investor, explains
-Laurence Kirsch, a transmission expert with Madison, WI–based
consultancy Christensen Associates. "When you build an AC transmission
facility, lots of people get to use it without paying just because
of how power networks work."
In
contrast, TransÉnergie has precise control over the Cross
Sound Cable. Those digital switches at the converter stations on
either end, designed and built by Swiss power equipment firm ABB,
consist of transistors sized for the grid’s kilovolt power
levels; acting much like valves, the switches on one end convert
a specified quantity of the grid’s AC power into direct current
(DC) and send it down the line to be converted back into AC on the
other end. The result is that the Cross Sound Cable Company can
lease space on its line and then program the switches to deliver
the specified kilowatt-hours of electricity. As on a private toll
road, there are no free riders: "If people don’t pay,
we close the road," says Donahue.
The Federal
Energy Regulatory Commission, which oversees wholesale power markets,
welcomed TransÉnergie’s proposal as a boon to competition
in the New York and New England power markets. But Blumenthal was
convinced that the cable was a bad deal for his state. He charged
that the project was "anticonsumer and antienvironment."
He wasn’t far off base: economists generally agreed that the
cable would siphon off cheap power, lowering supply and raising
prices in Connecticut. And to avoid interference with boat traffic
and fishing, permits that were issued to TransÉnergie required
that it bury its cables about two meters below the seabed, which
meant plowing a trench through cultivated oyster beds in New Haven
Harbor.
Blumenthal came
out swinging, in both the media and the courts. He challenged a
decision made by the Connecticut Siting Council, the state’s
overseer of power infrastructure projects, which had ruled in January
2002 that the long-term need to expand electric transmission capacity
in the region outweighed any short-term cost to Connecticut consumers
and temporary disruption of the oyster beds. Blumenthal also issued
a series of press releases predicting that the Cross Sound Cable
would cause "irreparable environmental damage while offering
no benefit to Connecticut"—a stance that garnered a substantial
amount of public support.
On April 9,
2002, a Connecticut Superior Court judge rejected Blumenthal’s
request for an injunction against the Cross Sound Cable Company,
clearing the way for installation of the cable. But two months later,
after technical blunders by the company, Blumenthal was back on
top. The Connecticut legislature had passed a moratorium on consideration
of permits for cross-sound infrastructure projects. And in May,
while burying the cable below the sound, ABB struck rock in the
seabed, which kept short sections of the cable shy of the minimum
depths specified in the transmission company’s permits. To
operate, the company now needed amendments to the permits. But Blumenthal
asserted in a legal opinion that granting them would violate the
legislature’s newly enacted moratorium. So for the next year
and a half, TransÉnergie was trapped: it couldn’t operate
without new permits, and it couldn’t get new permits with
the moratorium in place.
Digging
Out
August 14, 2003,
was a dark day for many people in the United States—though
not for officials at TransÉnergie. Just after 4:00 p.m.,
cascading outages starting in Ohio knocked out power to 50 million
people in Canada and the U.S., including many in Connecticut and
Long Island. It was just what TransÉnergie and sympathetic
officials in Washington needed to put the Cross Sound Cable back
on track.
The crucial
suggestion came from the Long Island Power Authority. Ed Grilli
and the authority’s chairman, Richard Kessel, asked their
grid operators whether the Cross Sound Cable could help them get
the lights back on. According to Grilli, they said it "absolutely
would." Grilli contacted the office of New York governor George
Pataki, who set up a conference call late that night with U.S. Department
of Energy officials, grid operators in New York and New England,
and Donahue, who is CEO of both TransÉnergie and its Cross
Sound Cable -subsidiary. Soon afterward, U.S. energy secretary Spencer
Abraham issued an emergency order, and by early the next day the
company had energized its cable. "We had always planned on
being available if there was an emergency, so the facilities were
left in a state where it wouldn’t be difficult to turn them
on," Donahue says. "Within 12 hours we were transferring
power to Long Island, helping customers get energy—and most
importantly, helping provide stabilization to the grid while the
generators on Long Island were coming back on."
Abraham’s
emergency order was set to expire two weeks after the blackout,
but he extended it indefinitely, arguing that the grid was in jeopardy
until the cause of the blackout was determined. Abraham would not
rescind his order until May 2004, after the Energy Department and
Canadian investigators issued an exhaustive dissection of the blackout.
By then, nine months of operating experience and a radically altered
political environment had worked wonders for TransÉnergie.
Politicians,
like most of us, tend to take electrical power for granted. The
2003 blackout stripped away this sense of security. Suddenly local
and state officials were concerned about power grids’ vulnerability
to everything from lightning strikes to terrorism, which cast Trans-Énergie’s
cable in a new light: according to Donahue, the cable’s digital
switches helped stabilize voltages on neighboring lines on 135 occasions
between August 2003 and April 2004. Nine months of operation also
proved that the cable was not the dire economic or environmental
threat that Blumenthal had predicted. Prices didn’t rise dramatically,
and no damage to the oyster beds was documented. Indeed, without
the cable, Long Island would have had to pay an extra $15 million
to $18 million for replacement power in 2004, according to Long
Island Power Authority calculations.
On June 17,
2004, the Federal Energy Regulatory Commission warned Connecticut,
the Long Island Power Authority, and TransÉnergie to settle
their squabble within a week or face federal impositions they might
all regret. Grilli says he picked up the phone and found the Connecticut
regulators ready to talk. By deadline day they had a deal. Connecticut
agreed to let the Cross Sound Cable Company operate while it determined
how to finish burying the line. The Long Island authority agreed
to replace an aging cable between Long Island and southwestern Connecticut.
The authority, the Cross Sound Cable Company, and Connecticut Light
and Power chipped in $2 million apiece to an environmental trust
fund to benefit the sound.
By the end of
Thursday, June 24, all the Connecticut politicians had been located,
the deal was signed, and the press releases began to fly.
Fixing
the Rules
For TransÉnergie,
the victory had come at a high cost—about $20 million in legal
bills, lobbying efforts, and extra engineering costs on top of the
cable’s original $125 million price tag, not to mention lost
momentum in its bid to lead the emerging merchant-transmission market.
Trans-Énergie lost out to a competitor in a bid to build
a second merchant DC power line to Long Island last fall (but it
remains in the running to build a link from northern New Jersey
to Queens that would connect the New Jersey and New York grids).
Similar politi-cal dramas* could keep the merchant-transmission
market hobbled for years.
Participants
in the Cross Sound Cable saga say that TransÉnergie could
have surmounted its political obstacles sooner. Donahue wishes his
firm had surveyed the bedrock along the cable route more intensively.
He also wishes it had "educated" Connecticut politicians
on the -cable’s benefits early on. (TransÉnergie had
brought in United Illuminating partly to help it master the local
political landscape, but insiders say the partner did little to
help sell the project.) Grilli, a veteran of New York politics,
says Trans-Énergie also should have responded more aggressively
to Blumenthal’s high-profile attacks. "TransÉnergie
just let him go out there and define the issue. It was extremely
difficult to wheel that back."
The larger problem,
of course, is the mishmash of state and federal rules that govern
power transmission, which leaves entrepreneurs like Donahue vulnerable
to political attack. Power-transmission experts like Sally Hunt
say the merchant--transmission market won’t be stable or profitable
until the companies, power authorities, and politicians involved
hash out a reasonable process for coordinating regional investments
in power transmission. A good place to start, according to Hunt,
is with the rules about how transmission services are bought and
sold, which must be redesigned to reward the improved reliability
that the most sophisticated devices deliver.
These issues
are highly technical and not at all sexy. But the alternative to
sorting them out—and opening the door for future Cross Sound
Cables—could be regular blackouts of historic proportions.
Power politics "doesn’t make big headlines, but it’s
really the important issue," says Hunt. "It could really
prevent the development of good technology."
