Today’s LiveWire Spotlight is on NERC’s initial report submitted to FERC to provide a continent-wide analysis of the use of Technical Feasibility Exceptions and their effect on BES reliability.

In it, NERC provides hard numbers which establish how often the TFE process has been invoked over an 18 month period since it took effect on January 1, 2010 – including the fact that over 90% of all entities with identified Critical Cyber Assets have requested a TFE.

At present, FERC staff is reviewing the NERC’s TFE summary report and have not set a date for an official response. It is likely that the Commission will probe into the categories of TFE justifications as they appear to be excessively broad.
