CA-TIMES

California Energy Modeling for Policy Analysis

The California Energy Modeling Group is is organized by Dr. Sonia Yeh, Dr. Chris Yang and Dr. Joan Ogden. The group will initially focus on modeling the energy system of California using the Integrated Markal-Efom System (TIMES). The goal is to provide a tool that helps us analyzing the social, economic and technological impacts of future vehicle penetration within the integrated energy system.

Modeling Tool:  TIMES (The Integrated MARKAL EFOM System)

TIMES is a technology-rich (or typically called bottom-up) model that estimates energy dynamics over a long-term, multi-period time horizon within a reference energy system (RES). The TIMES model aims to supply energy services at minimum global cost (more accurately at minimum loss of surplus by reaching a supply-demand equilibrium with endogenous energy service demands) with perfect foresight.

Further details of the model, information about the program supporting the TIMES model, and model documentation can be found at: www.etsap.org/
