LIPA’s Electric System Reliability Continues to Lead New York State

November 12, 2007

Uniondale, NY-November 12, 2007-The Long Island Power Authority (LIPA) is pleased to announce that LIPA leads New York State in key reliability indices for overhead electric transmission and distribution systems. LIPA continues to lead other New York electric utilities, with overhead systems, with the shortest customer average interruption duration index (CAIDI). In September, 2007, the average service restoration time for LIPA customers who experienced a service interruption was 71 minutes, which is significantly superior to the rest of the state which averaged 129 minutes. LIPA has been the state leader in this category for the last ten years.

“Since LIPA took over Long Island’s electric system in 1998, about $2.5 billion has been invested in the infrastructure which, in part, reflects the superior performance during last weekend’s storm,” said President and CEO Kevin S. Law. “We had fewer outages and a quicker recovery from Noel-related service interruptions caused by high wind gusts and sustained winds on the East End. Though service interruptions are unavoidable, LIPA is working hard to keep them to an absolute minimum and to restore them as quickly as possible when they do occur.”

The reliability of the LIPA transmission and distribution system (T&D) performed at an outstanding level. The frequency of electric service interruptions (SAIFI) was 14.1 months between interruptions on average. This is well ahead of the other New York state electric utilities with overhead systems, which average 11.0 months between interruptions.
