COLD WEATHER ASSESSMENT & EOP-012 AUDIT READINESS

COLD WEATHER ASSESSMENT & EOP-012 AUDIT READINESS

OVERVIEW

Extreme cold weather spells over the last decade have created a strain on
the Bulk Electric System (BES). In response, NERC has developed reliability
standards designed to regulate cold weather preparedness, ensure that
Generator Owners (GOs) maintain operational reliability during cold weather
events, and require that appropriate freeze protection measures be
implemented. NERC Standard EOP-011-2 is the current standard in effect. On
October 1, 2024, EOP-011-2 will retire and EOP-012-1 will become
enforceable, or possibly EOP-012-2, which has been filed and is currently
pending final regulatory approval.
