The National Institute of Standards and Technology (NIST) has released version 1.0 of the “Framework and Roadmap for Smart Grid Interoperability Standards” and an expanded second draft of the “Smart Grid Cyber Security Strategy and Requirements”.

The Framework describes a high level conceptual reference model for the smart grid and identifies 75 existing standards that are applicable, or likely to be applicable, to the ongoing development of the smart grid in the US.

A total of 70 gaps requiring entirely new standards to be developed were also identified in the Framework, and of these 15 have been selected as priorities for completion before the end of 2010.

The cyber security strategy identifies more than 120 interfaces that will link diverse devices, systems, and organisations engaged in two-way flows of electricity and information, and classifies these connections according to the risks posed by a potential security breach. In addition it lists a total of 67 standards that have been identified so far as relevant to cyber security in the smart grid.

The strategy is now undergoing a second round of public review, and is expected to be finalised in early summer.
