IEC PAS 62746-10-1:2014-02(en), originally designated as OpenADR 2.0b profile specification, is a flexible data model to facilitate common information exchange between electricity service providers, aggregators, and end users. The concept of an open specification is intended to allow anyone to implement the two-way signalling systems, providing the servers, which publish information to the automated clients, which subscribe the information. This OpenADR 2.0 profile specification covers the signalling data models and includes information related to specific DR (Demand Response) electric reduction or shifting strategies, which are taken at the facility. The PDF version of the standard is accompanied by Profile B Schema files.
