Methodologies that are briefly described in this document include an “Energy Forecast” utilized by the Secretaría de Energía de Mexico (Energy Secretariat of Mexico, SENER), integral resource planning (IRP), demand-side management (DSM) and, in more detail, the systemic planning for Baja California, Mexico. The latter integrates the effects of the saving and efficient use of electric energy and of reducing pollutant emissions into the environment.
