ISO/IEC 15067-3:2012(E) specifies an energy management model for programs that manage the consumer demand for electricity using a method known as "demand response". Three types of demand response are specified in this standard: direct control, local control and distributed control. It replaces ISO/IEC TR 15067-3, first edition, published in 2000, and constitutes a technical revision. It includes the following significant technical changes with respect to the previous edition:
- the demand response options have been expanded;
- distributed energy resources such as local generation and storage have been included;
- the terminology for demand response has been aligned with smart grid.
