"The 2015 Energy Sector-Specific Plan (SSP) was developed in accordance with the 'NIPP [National Infrastructure Protection Plan] 2013: Partnering for Critical Infrastructure Security and Resilience', which guides the national effort to manage risk to the Nation's critical infrastructure. The U.S. Department of Energy (DOE), as the Sector-Specific Agency (SSA) for the Energy Sector, led the development of the 2015 Energy SSP in close collaboration with its sector partners. A myriad of Energy Sector partners exist in both private and public sectors in the Critical Infrastructure Partnership Advisory Council (CIPAC) framework, under which the Electricity and Oil and Natural Gas Subsector Coordinating Councils (SCCs) and the Energy Government Coordinating Council (GCC) operate. Energy Sector partners have developed a valuable and increasingly trusted partnership in the past decade, which has been the cornerstone of the Nation's integrated risk management approach to critical infrastructure security and resilience. The Energy Sector is characterized by widely-diverse infrastructure components, a multifaceted operational environment, and complex ownership and regulatory structures. Further, the Energy Sector provides one of the key lifeline-functions upon which all other critical infrastructure sectors rely--the Nation's security and economy depend on it. In turn, the Energy Sector depends on many other critical infrastructure sectors, such as transportation, information technology (IT), communications, water, and financial services. In addition, the sector faces evolving threats and risks, such as natural disaster events, cyber and physical security threats, aging/failing infrastructure, and the potential shortage of a skilled workforce."
