Will The Outages Ever Cease?

Con Ed can’t get a break as the power goes out in Staten Island, affecting 16,000 “customers”*:

The latest power failure occurred as the utility and the city braced for a second summer heat wave that could endanger a fragile electrical network in Queens that is still being repaired.

The power failure on Staten Island began at 4:15 p.m. when three overhead lines were damaged — just 12 hours after Con Ed announced that electricity had been restored to the last customers in the Queens blackout. Around 10 p.m., Con Ed said, power was restored to all of its customers on Staten Island. The term “customer” includes residential and commercial buildings as well as households.

Mayor Michael R. Bloomberg canceled plans to visit Queens last night to go instead to the affected areas of Staten Island. “The good news is the temperature is reasonably cool and we do expect to get everybody back very soon,” the mayor said last night in a news conference at Dongan Hills.

The mayor further noted the difference between above-ground and underground power lines:

He took care to distinguish between the power failure on Staten Island, which uses overhead lines, and the blackout in Queens, which relies mostly on underground networks.

“This is a very different situation than existed in Queens,” Mr. Bloomberg said. “Here, when a cable is out, they know that everybody downstream is not getting power, so their estimates are very good. In an underground system, there are multiple paths to every house, so they don’t have a way of knowing.” In Queens it took Con Ed four days to correctly estimate the number of customers without power.

*And don’t let the terminology fool you — 16,000 customers could turn out to be a lot of people.
