Utilities Divided Over Managing Power Flow

Travel Trailers The utility companies that operate on the part of the nation's electrical grid where last week's epic blackout began have fought for months over how best to manage the heavy and volatile flow of power across their lines and how to share information at moments of crisis.

Travel Agency At the center of the dispute was an effort by some utilities to create, in effect, two management bodies, an idea that others feared would only further fragment the way the daily energy flow was handled, and how communication would work in an emergency.

Last Minute Travel "My company and many others raised concerns," said Larry Bruneel, a vice president at International Transmission Company in Michigan. "We've been advocating a single entity in the Midwest to have operational control over the grid."

Aloha Airlines How the events of last week were handled by the utilities and their routine day-to-day oversight organizations is at the center of the investigation of what turned out to be the biggest blackout in North American history. Investigators are trying to determine whether the different utilities consulted with each other as the crisis grew, and what the Midwest Independent Transmission System Operator, one of the oversight groups in the region, did to try and manage the developing disaster.

Travel Agent The details of the bitter debate over the management of the Midwest section of the grid emerge from papers filed over the last year with the Federal Energy Regulatory Commission, the government agency that regulates how electricity is distributed on the country's power grid.

Travel Agents Officials with the commission had to intervene to try and settle one aspect of the fight among the utilities in the Midwest how to cope with the large, unanticipated flows of power that send electricity over vast portions of the grid when one company sells power to a distant one.

Discount Airfares Officials with International Transmission believed these electrical surges to be a great threat to equitable and safe management of the region. But officials with another utility, American Electric Power, contended that existing management structure was adequate to handle the challenges.

Travel Deals The organizations "have done an unparalleled coordination plan about how to assure the grid is reliable," said Craig Baker, senior vice president of regulation and public policy at American Electric Power.

Air Fares The federal officials ultimately did not resolve the question, and how the utilities will finally manage such specific events on the complex, vulnerable grid remains uncertain.

Travel Insurance "Right now, different functions that relate to the stability and reliability on the grid are handled by different entities," said Stephen G. Kozey, vice president, secretary and general counsel for the Midwest Independent Transmission System Operator, the organization favored by International Transmission to run the Midwestern grid.

Travel State Gov This seemingly arcane dispute took on fresh relevance yesterday as new details emerged on the timeline of last Thursday's breakdowns. They were provided by data that International Transmission said it had either collected from its own power lines or obtained from other Midwestern utilities.

Travel Trailer International Transmission, like all companies in the region where the blackout began, has some interest in putting the best face on its own response to cascading failures on its borders and finally within its own part of the grid.

Ata Airlines But according to the data it made public, a crucial outage of two major transmission lines in Ohio at 4:09 p.m. effectively cut the state in two and forced electricity to take a roundabout path through Indiana and Michigan to reach the power-hungry area that includes Cleveland.

Travel Agencies Those two lines, Mr. Bruneel said, were owned by American Electric Power, and when they "tripped," or stopped transmitting power, that "pushed it past the point of no return," making a wider blackout inevitable.

Travel Guide Officials with American Electric dispute nearly everything about International Transmission's interpretation of the events. Automatic devices operated just as they were supposed to in shutting down the two transmission lines at 4:09, said Melissa McHenry, a spokeswoman for the company.

Time Travel Mr. Baker said, "Had they not tripped, they were loading to a level that may have led them to burn down." He said that sudden catastrophic failure could have caused an even wider blackout. He said the industry monitor that tracks American Electric's dealings on the grid, P.J.M. Inteconnection, had a good record of communicating with the other management entities on the Midwestern grid.

Travel Lodge Throughout yesterday, companies and industry groups defended their actions and focused on evidence that showed they had acted appropriately as the power failures spread.

Lowest Airfares Officials from the Midwest Independent Transmission System Operator, for instance, said that they had spoken repeatedly with officials from companies controlling power lines in Ohio as problems began to crop up there. But their officials would not describe the substance of those conversations.

China Airlines Representatives of Midwestern consumers of electricity said that the fight over the power management umbrella is secondary to the question of how well all the groups and companies in the region plan and coordinate actions in a crisis.
