The operators of New York’s electric grid believe a repeat of 2003’s blackout- when the state lost about 80 percent of its generation capability in about six seconds-is unlikely.
The New York Independent System Operator says there are stricter standards and better operator training now. Grid operators also are better able to see and respond to problems.
The industry says it has mostly addressed the failures blamed on a tree branch in Ohio that touched a power line and set off outages that cascaded across eight states and parts of Canada on Aug. 14, 2003, knocking out power for 50 million people.
