Basic Description of a TIMES Process

  • A process converts input commodity(ies) to output commodity(ies)

  • Each process is linear (e.g. output proportional to input, investment and fixed O&M costs scale with capacity / variable O&M scale with activity)

    • A power plant converts input fuel (e.g., coal/oil/gas/nuclear/renewable source) in electricity

    • A plug-in diesel hybrid car can be modelled as a process that converts electricity and/or diesel to passenger-miles

  • A typical national model may have ~1000 processes
