Improvements make repeat of last year's Ohio blackout unlikely, regulators say

 

By Jim Mackinnon, Akron Beacon Journal, Ohio -- July 16

Chain saws have toppled overgrown trees under thousands of miles of electric transmission lines. Computerized monitoring systems are upgraded. People who operate utility control rooms are better trained.

Those improvements and others to the electric grid since the historic Aug. 14 blackout make a repeat of that unlikely this summer, utility representatives, regulators and others testified Thursday in Cleveland.

With memories fading of flashlights, flickering candles, melted ice cream, a lack of traffic lights, TV or air conditioning, and a Cleveland water system that stopped working, Congress needs to enact stalled energy legislation now, said Ohio Gov. Bob Taft and others. The federal government needs to put into law mandatory electric reliability standards that include stiff penalties for noncompliance, they said.

"In my view, it's inexcusable" that Congress has not acted, Taft said. A comprehensive energy bill has been held up for more than a year. "It's been stalled because of other issues, peripheral issues," Taft said.

A lot of work has been done and continues to be done to make the grid more reliable. Another large blackout is less likely, Taft said. Electricity use peaks in the heat of July and August as air conditioners in homes and businesses kick in and work harder, putting a large strain on the grid.

"The chances of a blackout are far less. Everybody is focused on it," Taft said. "The oversight is still improving."

The cascading blackout that spread across eight states and parts of Canada on the afternoon of Aug. 14 got its start in FirstEnergy Corp.'s system, when three power lines overheated and sagged into trees in Northern Ohio.

Because of confusion at FirstEnergy and among other overseers of the grid, coupled with an inadequate and sometimes nonfunctioning grid-monitoring system, the blackout spread in the blink of an eye before it could be isolated and contained.

As a result, tens of millions of people were left without electricity, and some estimates put losses from the blackout at $6 billion. A subsequent U.S.-Canada investigation concluded that FirstEnergy did not follow voluntary industry standards in critical areas such as cutting down vegetation under power lines, and that others also failed to meet standards.

"If 50 million (people without electricity) isn't a wake-up call, I don't know what is," said Pat Wood, chairman of the Federal Energy Regulatory Commission. He chaired Thursday's meeting, which was sponsored by FERC and held at the Renaissance Cleveland Hotel.

Mandatory reliability standards need to be locked into law, Wood said.

Industry peer pressure works to make sure that utilities follow rules and guidelines, but that pressure cannot be sustained over years, he said.

"That's why it has to be institutionalized," Wood said. The utilities and organizations that administer the grid have been doing a decent job of cutting down trees, improving training and upgrading their tools, he said.

Overgrown trees were a major factor in the Aug. 14 blackout and in seven previous major outages, a draft federal report released at the meeting showed.

The FERC report said utilities across the nation have done extensive tree cutting and other vegetation management under high-voltage lines since the blackout. But the report, which will be sent to Congress, also said there was little uniformity in how utilities managed vegetation. In some cases, utilities said they were hindered by federal and state agencies from cutting down trees or applying herbicides because of environmental and other concerns.

Since the blackout, FirstEnergy has improved training for its transmission operators, conducted drills and developed new emergency response protocols, said Tom Burgess, the utility's director of energy delivery structuring. A new computer monitoring system, ordered before the Aug. 14 blackout, has been installed, he said.

FirstEnergy has also conducted foot patrols and aerial flyovers of its 15,000 miles of transmission lines, spokesman Ralph DiNicola said.

"We're feeling pretty good," said Chuck Jones, senior vice president for energy delivery at FirstEnergy.

More investments must be made throughout the nation's massive, but increasingly congested, transmission system, Burgess said. The deregulation of electricity markets is placing greater strains on the grid, which was initially designed to serve local markets but is now being used to send power great distances, he and others said.

"Without investment, the grid will not be able to keep up with the demands placed upon it," Burgess said. "The more the grid is used in ways for which it was not intended, the greater risk we run of failures."

A representative from the Midwest Independent Transmission System Operator, which oversees and manages part of the grid in FirstEnergy's territory, said his organization has made important improvements since the blackout. For one thing, the Midwest ISO and neighboring regional transmission organizations are doing a better job of communicating among themselves to better manage electricity loads across the grid, said Clair Moeller, vice president of the Midwest ISO.

"The most important thing we did to prepare for this summer, unfortunately, was last summer," Moeller said. "It clarified our thinking."
