Preface Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the Canadian Advisory Committee (CAC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T). At the time of publication, ISO/IEC TR 15067-3:2000 is available from ISO and IEC in English only. CSA will publish the French version when it becomes available from ISO and IEC. Scope The model for energy management presented in this Technical Report is generic and representative of a wide range of situations. Since one model cannot be completely comprehensive other models or operating modes may be more appropriate for certain applications. This model for energy management accommodates a range of load control strategies. Examples of implementations that could be described with this model include: the CELECT Intelligent Load Management System in the United Kingdom. The utility transmits electricity cost data and forecasted outdoor air temperatures to residential heater controllers; the "bleu, blanc, rouge" technique used by Electricit de France to announce price tiers one day in advance. The tier signal is displayed using a blue, white or red light to alert the customer; real-time pricing experiments by Consolidated Edison of New York and by Pacific Gas and Electric, both in the United States.
