Midwestern Power Grid Coordinator Takes Steps to Prevent Major Blackout

Milwaukee Journal Sentinel - April 9, 2003

New computers, alarm systems and increased staffing are tangible steps taken by the coordinator of the Midwestern power grid to prevent a blackout on the scale of Aug. 14, 2003, a report this week found.

The report analyzes steps taken by the Midwest Independent Transmission System Operator, based in Carmel, Ind., since the nation's worst-ever blackout last summer. The Midwest group was taken to task in a report released Monday by the U.S.-Canada task force investigating the outage.

In its own report Wednesday, the North American Electric Reliability Council says the Midwest group has a much better ability to view the transmission system it's responsible for than it did last summer.

The grid operator, which is responsible for reliability of the grid stretching from eastern Wisconsin and Illinois to western Pennsylvania, was found to have been unaware of problems in Ohio, where the blackout started, until just moments before the outage.

It had a poor ability to see the entire transmission grid in its region or to see problems developing in Ohio, and it failed to notify other regions of problems in the Midwest, a joint U.S.-Canada task force said.

The blackout stretched from Michigan to the Northeast and left 50 million people without power. The outage heightened attention to problems on the transmission system across the country and in Wisconsin, home of one of the most congested high-voltage lines in the nation.

The Midwest system operator is the same group that has come under fire from Wisconsin utilities, energy customer groups and regulators because of its plans to start a real-time energy pricing market that Wisconsin interests say could penalize the state because of its weak transmission system.

Changes within the Midwest coordinator's Carmel, Ind., control room since Aug. 14 include installation of a new computer system with screens able to visualize all major power lines on the Midwest grid. They also include advanced alarm filtering and an improved energy management system that the audit report said "greatly increased monitoring" of the Midwest group's footprint and other reliability areas.

But the report also recommends that the Midwest group beef up the training of its personnel and monitor its utility members to ensure that local utilities are prepared to take abrupt action to intentionally shut off power in local areas to prevent a problem from cascading to a blackout of the scope of Aug. 14.

"We have implemented a variety of tools to greatly enhance our visibility of the system and improve reliability," said James Torgerson, the Midwest group's president and chief executive. "This report confirms that we are making significant strides forward."

But a better way of viewing what's happening on the grid doesn't solve another critical problem facing the electric utility industry after last summer's blackout, said Jose Delgado, president and chief executive of Pewaukee-based American Transmission Co.

The utility industry needs mandatory reliability standards to be passed by Congress, with penalties for utilities that violate standards by allowing more electricity to pass along their lines than their transmission lines can handle, Delgado said.

The U.S.-Canada task force, echoing findings of a task force created after a blackout in the far West in the late 1990s, recommended that reliability standards be made mandatory. The standards are included in an energy bill now stalled in Congress.

Cathy Boies, manager of the Customers First! coalition of Wisconsin energy customers and municipal utilities, said it is clear that the Midwest group has made progress since Aug. 14 on its commitment to reliability.

"More power to them, but let's continue down that path rather than focusing on these markets and stay with reliability coordination, which was the original purpose of (the Midwest independent system operator)."

The Midwest group had delayed plans to start its energy trading market this spring because of a renewed commitment to reliability, but it filed plans with federal regulators last week to start its energy market on Dec. 1.
