Primary Objective:Develop a series of supply curves or other representations that can be used to model the non traditional technologies deemed capable of providing significant generation resources over the next decade or less.

Expected Deliverables:A set of equations and/or projections of supply that can realistically be expected to be made available I an economicallyfeasible fashion at a given price or prices along with output and emissions characteristics
