Advent of a national “super grid” growing out of
the August 14 blackout across much of the Midwest and
Northeast is not likely, regional transmission operators
(RTOs) and others involved in the industry suggest.
Insiders cite technical and political barriers
that will likely be impossible to overcome. What is more
likely, the industry says, is more robust regional
transmission organizations (RTOs) managing electrical
systems over broad geographic areas with a high degree
of regional cooperation with nearby entities. Also
likely, grow in energy storage, alternative energy, and
easier approvals for transmission projects.
Most
agree large interconnected electrical systems are
inherently more stable than small islands, but they also
tend to agree there is a point at which making a large
system larger provides no additional benefit.
Strong RTOs can foster compatible technology,
operating procedures, maintenance standards and outage
coordination, and it can also provide a seamless market
structure that allows for easy, and inexpensive access
to the grid and generating resources. “We also support a
regional market monitoring system that can see and
analyze data across the same broad geographic region,”
said officials at the California ISO, which is awaiting
approval from the Federal Energy Regulatory Commission
(FERC) to become a RTO. However, unlike other areas of
the country, CalISO is running the regional grid, said
CalISO CEO Terry Winter.
At
storm’s center
Being able to see and
analyze accurate data within the transmission system
might have helped avoid the August 14 blackout, suggests
James Torgerson, president and CEO of the Midwest ISO
(MISO), which oversees the reliability of wholesale
power transmission in all or parts of 15 states and the
Canadian province of Manitoba.
From MISO’s
control room in Carmel, Indiana, Torgerson and his staff
watched the blackout unfold from its beginning, when
several small Cleveland-area line failures occurred in
the service territory of FirstEnergy Corp., a MISO
member.
Torgerson watched as the well-documented
blackout spread across 23 loosely controlled areas
within MISO and then into the Northeast and parts of
Canada (Indiana was not affected). Ultimately, some 50
million people lost power.
Torgerson blamed
outdated technology for exacerbating the outage. MISO
does not directly move power, its members do. MISO is
currently only a facilitator and will not obtain
significant control until March 2004. Then, said
Torgerson, MISO will begin coordination of energy
trading between utilities.
That increased
authority is critical, noted Standard & Poor’s in a
new analysis – Will the Lights Go Out on the Regional
Electricity Transmission Organizations?. MISO,
currently, "is responsible for regional system
reliability, it is not the control area operator for the
region, and thus lacks the ability to control key
operations of the transmission grid, especially when the
system is stressed." MISO members receive grid control
recommendations from the ISO, but whether to follow them
or not is optional, not a requirement, said S&P,
like Platts T&D, is a unit of The McGraw-Hill
Companies.
In March, however, MISO –which is
calling for $1.32 billion in grid upgrades over the next
five years-- will still not be the control area
operator, nor will it be when it and PJM complete
development of a common market by October 2004. "The
fact that PJM will have direct control over its system
while MISO will not, presents interesting challenges,"
said S&P. (In response to the blackout, S&P put
the credit ratings of Akron, Ohio’s FirstEnergy on its
CreditWatch list "with negative implications.")
PJM Interconnection, the New York Independent
System Operator, and the Independent System Operator New
England all operate centralized markets and run
real-time communication with system functions.
In the meantime, Torgerson and MISO control room
staff are on the telephone with members. But telephone
communication is slow when dealing with electricity,
which travels at the speed of light. Torgerson said MISO
–and all other RTOs/ISOs—desperately faster modes of
communication with members when system trouble is
identified.
"Today, we just talk to them, and
it's not quite as efficient," he said.
Mandatory rules, tough penalties
Supergrid or not, FERC commissioner William
Massey said in a conference with reporters and the
industry that: “I think the episode (the blackout) is
enough for all of us to conclude that we need mandatory
rules for reliability of the grid, and we need very
tough penalties for violators.”
Lynne Church,
executive director of the Electric Power Supply
Association agreed: ”We need tough, enforceable
reliability standards. We need independent operators of
regional grids whose jobs are to prevent the disruptions
that occurred last week from happening. And until we go
ahead and do that, this continuing regulatory and
legislative uncertainty is only going to exacerbate the
system.”
“Congress has a decision to make,
whether it's going to be part of the solution or part of
the problem,” said Church. If there's one thing that's
clear (from the blackout, it) is that the electricity
grid does not respect political state boundaries. It is
interstate; indeed, it is intercountry. And those who
would argue that states ought to control that portion of
the grid within their own states, I think are ignoring
reality.”
SMD. Will it go away?
But the blackout will likely retard FERC’s push
for a standard market design, said Leonard Hyman, senior
associate with consultant R.J. Rudden Associates. "I
don't think anyone cares about it now" because "it's not
an issue that has anything to do with reliability,"
Hyman said of the FERC proposal, which calls for uniform
wholesale power market rules administered by RTOs.
"I don't know if it will go away" altogether if
congressional opposition continues, but it definitely
will have less of a role than FERC originally
envisioned, Hyman said. But because the blackout covered
five areas overseen by RTOs or independent system
operators (ISO), it "may close down the ISO movement for
a while," Hyman said.
The outage also may blunt
any wholesale or retail restructuring movement because
it gave opponents of restructuring an opportunity to
blame deregulation for the collapse of the grid, Hyman
said.
The restructuring movement may “stop
wherever we are now,” Hyman said. Hyman also suggested
the outage could prompt federal lawmakers to include
federal siting authority for new transmission lines in
an energy bill, as suggested by FERC Commissioner
William Massey and others.
When the blackout
hit, “everyone jumped on construction, about how we
aren’t spending enough money, but we haven’t spent
enough money on the system for years and the ongoing
cost of the general unreliability of the system is about
$40 billion annually, just in the nation’s industrial
sector,” Hyman said.
Hyman said "more capital
spending is needed" to make up for the lack of
investments over the past several years. He estimated
that an additional $2.5-billion a year in transmission
investments is needed and about $5-billion per year in
distribution investments. Compared with the capital
spending done by utilities on a regular basis, "adding
another $7.5-billion in spending is not going to break
the bank," he said.
Bush
wants a “super highway”
The Bush
administration apparently plans to a three-year freeze
on FERC’s plan to create RTOs, which would control
electricity flow in their regions, be responsible for
upgrading the transmission system and pull authority
form both state regulators and electric utilities. But
Bush has publicly suggested he wants something of an
electricity “super highway,” something the current grid
and its control mechanisms cannot now manage. The grid
is now largely operated and regulated on a
state-by-state basis
The blackout clearly
demonstrates the need for a new national energy policy,
said. U.S. Senator Pete Domenici (R-New Mexico), the
chairman of the Energy and Natural Resources Committee.
“This outage clearly demonstrates how close the nation
is to its energy production and distribution limit."
ERCOT – WestConnect: Emphasis on technology,
consolidation There will not likely be a “super grid,”
but a new emphasis on technology, providing better,
faster switching, said Sam Jones, chief operating
officer of the Electric Reliability Council of Texas
(ERCOT).
And ERCOT, witch is only lightly
connected to regions outside of Texas will be making no
effort to establish new ones, said Jones. Instead, ERCOT
is beefing up its own system, with plans for 500 circuit
miles of new transmission. “At least that is the amount
currently under consideration,” noted Jones. “There is
definitely a push on for badly needed transmission,” he
said.
WestConnect (formerly Desert STAR) project
manager Charles Reinhold anticipates the blackout will
lead to consolidation within the transmission
infrastructure of the Rocky Mountains, the home of the
proposed entity. WestConnect was set up to become a RTO
and provide open grid access in a region that is
expected to encompass Arizona, New Mexico, Colorado and
portions of eastern Wyoming and western Texas.
But WestConnect will be functional “no earlier
than 2007,” said Reinhold, “and then only have limited
functionality until 2010.” And there is no telling what
the grid will actually look like, he said, adding “there
are some problems finding ways to get the transmission
lines built and determining who pays.”
A
for-profit national grid?
Still,
others, Richard J. Rudden, CEO of R.J. Rudden
Associates, Inc. for one, argue for a nationwide,
for-profit grid that is truly interconnected, and
managed under competent, appropriately funded, federal
regulatory authority. Rudden suggest FERC as the
regulatory authority, “at least it would put someone in
charge.”
But Rudden acknowledges huge hurdles in
the way of significant change:
- Low-cost regions do not want interconnecting grids
that enable companies in those regions to sell
low-cost power out of region into higher cost markets;
- State regulatory commissions do not want to cede
regulatory authority over transmission assets;
- Other factions do not want increased federal
control over the siting and certification of
transmission lines;
- Nor do they want the possibility of enhanced
federal rights of eminent domain, and;
- Investor-owned utilities do not want to be owners
of assets over which someone else has control.
But Rudden is not altogether optimistic about
the chances for a nationwide grid.
Significant
regulatory agency reform is needed, as is institutional
change, but “lawmakers will most likely go for the least
efficient, most conventional solution,” he said.
Industry consultant Robert Blohm suggests the
National Energy Reliability Council (NERC) be given the
authority and the power to make the grid system
reliable, as the agency itself has suggested.
“Right now NERC has no power,” said Blohm. “When
NERC was a gentleman’s club there was pressure among the
members and everyone cooperated. NERC is still a club,
but the members are not gentlemen anymore –now they are
fighting adolescents.”
Blohm’s point was not
lost on the agency. Said NERC CEO Michehl Gent in a
telephone press conference with the media: "I personally
am embarrassed and upset (by the blackout). This was
never supposed to happen."
