America's Power Grid Still Hangs Tough in Face of Winter Wallop

The past week’s arctic freeze has already battered the U.S. power system, threatening fuel supplies from the Midwest to the Northeast. Now, with a one-two punch of heavy snow and bone-rattling cold on the way, grid operators say this: We’re good.

“Everything looks to be on track to remain reliable,” Chris Pilong, director of dispatch for PJM Interconnection LLC, which stretches from Illinois to Washington D.C., said on a conference call Wednesday. “Maybe Sunday and into Monday of next week, we should get ourselves back to at least the freezing mark.”
