The California Energy Commission is working on developing parameters for its 10-year natural gas outlook to assess resource adequacy. At a June 28 workshop, commission staff took input on what factors to include in the analysis. Some participants recommended that the assessment not be limited to one model but include running several base-case scenarios. By employing multiple models, various demand scenarios arising from a possible increase in liquefied natural gas, coal-fired supplies, and\/or renewables could be addressed. Participants urged that environmental constraints on fuel switching also be included. ?If you look at it from different perspectives, the analysis will have a longer shelf life,? said Karen Griffin, CEC technical adviser to the executive director.
