U.S. Electric grid remains vulnerable
Feb 16 - Cincinnati Post Six months after the nation's worst blackout, experts say the electric grid is still vulnerable to widespread outages because many of the problems that contributed to the massive failure have not been resolved.
Among the few tangible steps taken toward strengthening the grid, according to several experts, are the intense scrutiny of the root causes and better intra-regional communication between power providers and grid operators.
However, a repeat of the havoc wreaked on Aug. 14, when outages in Ohio rapidly spread through seven other states and Canada, remains plausible so long as the industry remains "polarized" by regional interests and competing ideas about market design, both of which inhibit cooperation, said Lawrence Makovich, senior director at Cambridge Energy Research Associates.
Stalled energy legislation, which is being attached to a massive transportation bill now before the Senate, is intended to clear up some of these issues, but Makovich said it could still take the industry several years to make the requisite changes.
"Setting the goals is only half the battle," he said, adding that one of the stickiest issues will be determining who picks up the tab for upgrading the power lines and computer networks that are the technological backbone of the grid.
Nora Brownell, a commissioner at the Federal Energy Regulatory Commission, said power providers need not wait for an energy bill to be passed before taking action. New hardware and software, better employee training and aggressive vegetation management "could be implemented today" and would be useful regardless of what types of new federal rules are enacted, she said.
"It is extraordinarily inconceivable to me that 25 years after the first major blackout, that we're still talking about what needs to be done," Brownell said.
To spur investment in new transmission, experts argue, utilities need to be able to pass along more of the costs to consumers. And some say power providers should be allowed performance-based rewards for reliability. That said, it remains unclear if the enforcement of reliability standards will be in the hands of the government or the industry.
"We've been grappling with the issue of how to maintain reliability as the market evolves," said Eugene McGrath, chairman and chief executive of Consolidated Edison, Inc. If there's any silver lining from Aug. 14, he said, it is that the areas of vulnerability are better known.
That, in itself, reduces the risk of another cascading blackout, he said.
