1.1 Impact Evaluation Objectives and Scope The impact evaluation activities were aimed at determining: - › Gross electrical energy and peak demand savings at the meter and at the generator - › Available demand response (DR) capacity for de...
AI summary The impact evaluation objectives include assessing energy and peak demand savings, demand response capacity, net-to-gross ratios (NTGRs), effective useful life (EUL) of measures, and GHG emissions. Two evaluation types are outlined: comprehensive (reviewing baseline definitions, methodologies, parameters, and NTGRs) and condensed (reusing prior-year parameters). Evaluations occur every three years for most programs, with factors like program maturity and calculation complexity influencing the approach.
