SEPA produces the Catalog of Standards (CoS) as a reference to the Electric Grid community with the intent of it serving as a useful resource for utilities, manufacturers, regulators, consumers, and other Industry Grid stakeholders. The Catalog is a compendium of standards and practices considered to be relevant for the development and deployment of a robust, interoperable, and secure Modern/Smart Grid.

Each standard listed in the Catalog contains extensive information and has gone through a rigorous, multi-part review using objective criteria by industry experts. The Catalog also provides a key, non-exclusive, source of input to the National Institute of Standards and Technology (NIST) process for coordinating the development of a framework of protocols and model standards for an interoperable Smart Grid.
