1962-1963 Industry creates an informal, voluntary organization of operating personnel to facilitate coordination of the bulk power system in the United States and Canada. Four interconnected transmission systems are connected to three more systems, which form the largest electricity grid in the world. In January 1963, the North American Power Systems Interconnection Committee (NAPSIC) is formed.
November 9, 1965 Largest blackout to date occurs -- 30 million customers lose power in the northeastern United States and southeastern Ontario, Canada. New York City and Toronto among the affected cities. Some customers without power for 13 hours.
1967 Legislation (U.S. Electric Power Reliability Act of 1967) proposes creation of a council on power coordination. Although not enacted, the proposed legislation stimulates development of an industry-based electric reliability council.
1967-1968 Federal Power Commission (predecessor of the Federal Energy Regulatory Commission) recommends the formation of a council on power coordination with representatives from each of the nation’s regional coordinating organizations, to exchange and disseminate information and to review, discuss and assist in resolving interregional coordination matters.
June 1, 1968 National Electric Reliability Council (NERC) established by industry in response to the 1965 blackout and recommendation of the Federal Power Commission. Nine regional reliability organizations formalized under NERC. Also formalized are regional planning coordination guides maintained by NERC. Utilities maintain and practice voluntary operating coordination in accordance with NAPSIC operating criteria and guides.
July 13-14, 1977 New York City blackout occurs, leading to first limited reliability provision in federal legislation. Legislation enables federal government to propose voluntary standards, an authority never exercised.
1979 Report to NERC by Joseph Swidler, former chair of the Federal Power Commission, recommends on role of NERC in light of the Public Utility Regulatory Policy Act of 1978 (PURPA).
1980 NAPSIC becomes part of NERC, forming the NERC Operating Committee, and bringing reliability roles of operations and planning together in one organization. NERC adopts NAPSIC operating criteria and guides.
1981 NERC changes its name to the North American Electric Reliability Council in recognition of Canada’s participation and to more accurately reflect the broader scope of NERC’s membership.
1987 NERC forms committee to address terrorism and sabotage of the electricity supply system at the urging of the National Security Council and Department of Energy.
1992 NERC Board of Trustees states conformance to NERC and regional reliability policies, criteria and guides should be mandatory to ensure reliability in one of six Agreements in Principle. (At the time, NERC has no authority to enforce compliance with the policies, criteria and guides.)
1993 NERC publishes “NERC 2000,” a four-part action plan that recommends mandatory compliance with NERC policies, criteria and guides; and a process for addressing violations, built upon earlier Agreements in Principle.
1995 Federal Energy Regulatory Commission (FERC) issues Notice of Proposed Rulemaking on open access that encourages a more fully competitive wholesale electricity markets. NERC files six-point action plan to address the planning and operating reliability aspects of the NOPR.
1996 Two major blackouts in the western United States prompt Western Systems Coordinating Council (WSCC) to develop the Reliability Management System in which members enter voluntarily into agreements with WSCC to pay fines if certain reliability standards are violated. (WSCC, a regional reliability organization, is now Western Electricity Coordinating Council.)
1997 Electric System Reliability Task Force established by the Department of Energy, and an independent Electric Reliability Panel (“Blue Ribbon” panel) formed by NERC determine grid reliability rules must be mandatory and enforceable in an increasingly competitive marketplace. Both groups recommended the creation of an independent, audited self-regulatory electric reliability organization. NERC begins converting its planning policies, criteria, and guides into standards.
1999 Nine independent directors added to the NERC Board join the president and 37 industry stakeholder members in anticipation of NERC becoming an audited self-regulatory organization. Broad coalition of industry, state and consumer organizations propose legislation in the United States to create an electric reliability organization to develop and enforce mandatory reliability rules, with oversight in the United States by FERC.
2000 NERC appointed as the electric utility industry’s primary point of contact with the U.S. government for national security and critical infrastructure protection issues. NERC establishes the Electricity Sector-Information Sharing and Analysis Center.

Proposed reliability legislation first introduced in Congress by Senator Slade Gorton of Washington.
2001 NERC governance changes. Board replaced with a 10-member independent board. Stakeholders Committee created. (The Stakeholders Committee name was later changed to the Member Representatives Committee.)
May 1, 2002 NERC operating policies and planning standards become mandatory and enforceable in Ontario. August 14, 2003 North America experiences worst blackout to date, as 50 million people lose power in the northeastern and midwestern United States and Ontario, Canada. United States–Canada Power System Outage Task Force formed to investigate cause and make recommendations to prevent future blackouts.
February 2004 NERC Board approves Critical Infrastructure Protection Advisory Committee as permanent standing committee.
April 5, 2004 Final report of the United States-Canada Power System Outage Task Force on the 2003 blackout concludes most important recommendation for preventing future blackouts is for U.S. government to make reliability standards mandatory and enforceable.
Summer 2004 Bilateral Electric Reliability Oversight Group (BEROG) established as a forum for identifying and resolving reliability issues in an international, government-to-government context. BEROG grew out of the U.S.-Canada Power System Outage Task Force.
November 12, 2004 NERC translates operating policies, planning standards and compliance requirements into integrated and comprehensive set of 90 measurable standards called “Version 0 Reliability Standards.”
February 2005 NERC Board approves dissolution of the NERC Market Interface Committee and endorses continued cooperation and coordination with North American Energy Standards Board (NAESB).
April 1, 2005 Version 0 Reliability Standards become effective. Voluntary compliance expected as a matter of good utility practice.
