This presentation commences with an overview of energy efficiency obligations as a regulatory mechanism that requires obligated parties to meet quantitative energy savings targets through implementing cost-effective end-use energy efficiency. The presentation then outlines the steps involved in designing effective energy efficiency obligations.
