Utilities Await New Physical Security Standard

U.S. regulator takes next step in approving physical security standard

BY PHILL FELTHAM, Editor-in-Chief
Electricity Today Magazine

Recently, the Federal Energy Regulatory Commission (FERC) announced a proposal to approve the physical security reliability standard (CIP-014-1), submitted by the North American Electric Reliability Corporation (NERC) earlier in the year. This physical security standard is currently being developed in response to an armed assault that occurred on a California substation in early 2013.

Initially, FERC determined that...
