FERC Takes Action to Enhance Reliability
of the U.S. Electric Grid
September 18, 2025

Docket Nos.: RM24-4-000, RM20-19-000, RM24-8-000, RM25-8-000, RD25-7-000
Today, FERC voted unanimously to approve a suite of actions focused on modernizing the
reliability and security of the nation’s Bulk Power System in the face of threats in cybersecurity,
supply chain risk management, and extreme cold weather.
“The reliability and security of our country’s electric system is essential to our
economic prosperity, national security, and everyone’s wellbeing,” FERC
Chairman David Rosner said.  “The actions we are taking today are necessary
to ensure our grid is resilient for all Americans today and in the future.”
The Commission approved the following:
Final Rule on Supply Chain Risk Management Reliability Standards Revisions (RM24-4000 and RM20-19-000).  The final rule largely adopts the Commission’s Notice of Proposed
Rulemaking from September 2024 directing the North American Electric Reliability
Corporation (NERC) to address supply chain risks in new or modified Reliability Standards. 
These Standards will also extend existing Supply Chain Risk Management Standards to
certain network-connected equipment to further protect the electric grid from outside
threats.  The final rule is effective 60 days after publication in the Federal Register, and NERC
must provide responsive modifications within 18 months of that effective date.
Notice of Proposed Rulemaking on Virtualization Reliability Standards (RM24-8000). Proposes to approve four new and 18 modified definitions in NERC’s Glossary of
Terms as well as 11 modified Critical Infrastructure Protection (CIP) Reliability Standards to
enable compliant virtualization. While existing CIP Standards were designed with the
assumption that hardware and software are installed and protected on-site, these
modifications are designed to protect virtual and cloud-based technologies applied within
the Bulk Power System, enabling cost-saving efficiencies through technological
modernization.  The Commission also seeks public comment on NERC’s proposed changes
to its existing technical feasibility exception program.
Notice of Proposed Rulemaking on Critical Infrastructure Protection Reliability
Standard CIP-003-11 (RM25-8-000). Proposes to approve a revised Reliability Standard to

enhance the cybersecurity of low-impact Bulk Electric System (BES) Cyber Systems against
the threat of a coordinated cyber-attack by establishing new security requirements for
communications and system management.  The Commission also seeks public comment
on the evolution of threats to low-impact BES Cyber Systems and whether it would be
beneficial for NERC to perform a study or develop a whitepaper addressing these evolving
threats.
Order Approving Extreme Cold Weather Reliability Standard and Directing Data
Collection (RD25-7-000). Approves NERC’s proposed revisions to Reliability Standard EOP012 (Extreme Cold Weather Preparedness and Operations), improving the currently
effective Standard consistent with the Commission’s directives in its June 2024 Order.  The
revised Standard, effective October 1, 2025, improves clarity in communications
requirements and helps ensure that needed power is available for the people and
businesses which rely on it during extreme cold weather events.  The order also directs
NERC to file comprehensive biennial informational filings starting in October 2026 through
October 2034 to assess whether the Standard adequately addresses reliability concerns and
guides potential future modifications.
