HOUSTON, June 9 Public Service Enterprise
Group's (PEG.N) New Jersey utility reported about 75,000
customers lost electric service on Monday after a breaker
failed, causing a fire at a switching station in West Orange,

a heat wave that has brought record temperatures to New York

adequate, said Ray Dotter of PJM and Ken Klapp of the NY ISO.
PJM, which stretches from North Carolina to Michigan, is
the largest power grid operator in the United States.
