In comments filed last month, the North American Electric Reliability Corporation (NERC) told the National Institute of Standards and Technology (NIST) that it should focus hard on coordination of standards as it works on its Proposed Framework for Smart Grid Interoperability Standards.

NERC simultaneously stressed the differences between the three types of proposed standards: Interoperability Standards, System Security Standards and Reliability Standards – and the ultimate need for streamlined, real coordination between the different standards.

“Although the voluntary Interoperabilty Standards proposed by NIST are designed to achieve a different purpose from the NERC mandatory Reliability Standards, it is critical to the continued reliability of the bulk power system that the two bodies of standards be compatible and complementary,” the Nov. 9th comment noted.

NERC also stressed the importance of cyber security to smart grid technologies and encouraged NIST to integrate adequate cyber security protection, at all levels (device, application, network and system) in the development of its Interoperabilty Standards.

While NERC CIP Reliability Standards provide for the reliable and safe operation of the bulk power system by preventing the unauthorized cyber and physical access to critical assets and critical cyber assets, NERC commented, there is a need to develop additional cyber security protection for distribution facilities in the development of Smart Grid Interoperability Standards to address, for example, security aspects of interoperability at the distribution level.
