Presentation Notes
DOE is the Sector-Specific Agency (SSA) responsible for critical infrastructure protection for the energy sector (electricity, oil and natural gas), as directed by Homeland Security Presidential Directive (HSPD) 7 Our role as SSA continues through the Feb 12, 2013 Presidential Policy Directive (PPD) 21 to provide analysis, expertise, and other technical assistance to critical infrastructure owners and operators and facilitate access to and exchange of information and intelligence necessary to strengthen the security and resilience of critical infrastructure; DOE’s Office of Electricity Delivery and Energy Reliability (DOE-OE) champions effective risk management programs, secure and reliable information sharing and situational awareness, and relevant research and development (R&D) activities through the CEDS program. In 2006, CEDS championed the first Roadmap and updated it in 2011. The Roadmap to Achieve Energy Delivery Systems Cybersecurity is the Energy Sector’s synthesis of critical control system security challenges, R&D needs, and implementation milestones. It provides a strategic framework to align activities to sector needs, coordinate public and private programs, stimulate investments in control systems security, and a path toward a common vision. The Energy Sector’s vision is that: By 2020, resilient energy delivery systems are designed, installed, operated, and maintained to survive a cyber incident while sustaining critical functions. To achieve this vision, DOE-OE has established relationships and lines of communication with vendors, energy utility end-users, the intelligence community, universities, and other government entities such as DHS, NIST, DOD, and other stakeholders across the energy sector. DOE-OE is also a formal member of NITRD. - Coordinated by the National Science Foundation, the Networking and Information Technology Research and Development (NITRD) is a multi-agency collaboration which shares information on its budgets, coordination plans, and technical activities ensuring that key issues are addressed, duplication is eliminated, and program budgets are leveraged. - Established as part of the High-Performance Computing Act of 1991 as amended by the Next Generation Internet Research Act of 1998 and the America COMPETES Act of 2007

Conclusions

Our electric power industry experiences unprecedented changes at a stunning pace

Significant supply side changes that include continued rapid growth of renewables and changes in our thermal power generation mix may lead to changes in markets, system operations, and system planning

New consumers and new technologies may alter our demand situation significantly and lead to more uncertainty in demand forecasts

Smart grid offers both opportunities and challenges

New approaches to data management, analysis, and modeling will be needed
