Energy Efficiency Screening
Energy Efficiency Utility (EEU) Orders of Appointment require EEUs to design and implement cost-effective energy efficiency programs. Energy efficiency measures offered under the EEU program are screened based on the societal cost-effectiveness test. The Department of Public Service (Department) developed a cost-effectiveness screening tool for use by the EEUs. The Commission requires EEUs to use this screening tool to determine that measures implemented are cost-effective.
The EEU program has developed a Technical Reference Manual that helps serves as documentation for the inputs to the cost-effectiveness screening tool. The manual provides the technical description of all prescriptive and some custom energy efficiency measures.
The Technical Reference Manual is maintained by Efficiency Vermont, and is updated annually using the work of the Technical Advisory Group. The Technical Advisory Group includes members of Efficiency Vermont, City of Burlington Electric Department, Vermont Gas Systems, Inc., and the Department. The Group focuses on reviewing and approving the methodology and associated assumptions underlying measure-savings calculations that are included in the Technical Reference Manual.
EEU Avoided Costs
The EEU Process and Administration Document calls on the Department to biennially propose updates for avoided costs, externality adjustments, and other screening components for use by the EEUs when they perform cost-effectiveness screening of energy efficiency measures.
Under the process set forth in the Process and Administration Document, the Commission provides an opportunity for other interested persons to file comments and request a technical workshop before ruling on the Department’s proposed changes.
