(Reuters) - The New York State Public Service Commission on Thursday said National Grid Plc
The investigation found that National Grid's Brooklyn Union Gas Company (KEDNY) and KeySpan Gas East Corp (KEDLI) failed to inspect work completed by its contractors during construction at sufficient intervals and allowed work to be completed by inspectors who were not properly qualified to do the work.
The commission has ordered the two utilities to provide explanation on why it should not commence a penalty action against them.
KEDNY, serving the New York City borough of Brooklyn, has about 1.2 million customers, and KEDLI, serving Long Island, has 590,000 customers.
