NEC 2008 Article 708 Critical Operations Power Systems (COPS) 708.1 Scope - Applies to power systems, HVAC, fire alarm, security, communications, and signaling systems in facilities classified as “critical” by: Any governmental agency having jurisdiction Municipal, state, federal, or other codes Facility engineering documentation establishing the necessity

May be applied to entire facilities or to designated areas within a facility 708.2 Definitions Critical Operations Power Systems (COPS) Power systems for facilities or parts of facilities that require continuous operation for public safety, emergency management, national security, or business continuity. Designated Critical Operations Areas (DCOA) Areas within a facility or site designated as requiring critical operations power.
Critical infrastructure is “critical” for a reason • Water and wastewater facilities can be classified as critical infrastructure because they: Protect public health and safety Expedite disaster recovery Safeguard the environment Allow businesses to function
The Reliability of the Water Sector Depends on a Complex Power Grid Pump Stations Water Plants Wastewater Plants Wholesale Suppliers Investor Owned Utility Generators Independent Power Generators Power Marketers Power Exchange (RTOs/ISOs) Transmission Retail Electricity Providers
The Electric Power Industry Before 2005 • 18 Reliability Coordinators • Managed reliability and operation of wholesale markets • Voluntary Membership • Competing interests • North American Electric Reliability Council (NERC) • Ten Regional Reliability Councils • 140 control areas • No Enforcement Powers • Voluntary Cooperation
2003 – The Tipping Point • Trouble began at 12:15 PM • Inadequate situational awareness by FirstEnergy • Inadequate tree-trimming by FirstEnergy • 345kV Sammis–Star overload trip at 4:06 PM – essentially complete by 4:13 PM • High speed cascading lasted approximately 12 seconds • 263 power plants shut down (531 generating units) • Over 50 million people in the Northeast US and the Province of Ontario were out of power up to 3 days
The Energy Policy Act (EPAct) of 2005 • NERC’s mission: • To ensure the reliability of the bulk power system in North America. The Reorganization • NERC reorganized as the North American Electric Reliability Corporation • Granted powers to enforce its own reliability standards • Consolidation of Regional Entities • 131 Balancing Authorities (BAs)
EPAct and the Energy Markets • FERC: • Regulates the transmission and wholesale sales of electricity in interstate commerce. • State Public Utility Commissions: • Regulate retail electricity sales to consumers. RTOs and ISOs: • Serve roughly two-thirds of all US electricity customers • Operate organized wholesale electric markets • Provide transmission service • Interconnect new resources to the transmission grid • Financial interests must be kept at arms length from reliability interests

Emerging Risks to the Electrical Grid Risk Reliability Source: NERCs 2009 -2018 Long-Term Reliability Assessment
Shift toward renewable energy will affect grid reliability Variable Generation is the term for generation based on renewable fuel sources such as wind and solar. NERC’s 2009 Long-Term Reliability Assessment estimates that 229,000 MW of wind generation resources may be added by the year 2018. How variable generation affects the reliability of the bulk power system: Power output changes according to wind or weather These resources are not dispatchable to grid operators Renewable sources are less predictable than conventional generation.
The Smart Grid - Challenge or Opportunity? Section 215 of the Federal Power Act: §215(a)(8) “The term ‘cyber security incident ’ means a malicious act or suspicious event that disrupts, or was an attempt to disrupt, the operation of those programmable electronic devices and communication networks including hardware, software and data that are essential to the reliable operation of the bulk power system.” While the smart grid promises to bring greater efficiency and functionality to grid operators, it also poses a significant security challenge. NERC assessment - much of the grid is vulnerable to cyber attack. FERC examined AURORA compliance: Only 7 of 30 companies had mitigated the vulnerability Only 2 of 30 had a good cyber security posture.
Pulling the Plug on the Grid • Article 708 requires critical systems to operate indefinitely while completely cut off from the electric, gas, and water utility grids. Successful compliance requires: Planning and Assessment Engineering Beyond Traditional Approaches Rigorous Maintenance
Risk Assessment (708.4) • Planning • Engineering • Maintenance Conduct Risk Assessment per NFPA 1600 “Disaster/Emergency Management and Business Continuity Programs” Identification of natural and man made hazards Assess specific vulnerability of the electrical system Develop mitigation strategy
