This protocol supports estimating savings at the end user for lowering voltage, which can reduce consumption for some devices. The protocol applies to qualifying projects and provides a methodology for estimating savings with “canned” VO factors to simplify savings estimation and offers delivery verification guidance. An eligible project is one that is mostly residential, is able to reliable estimate average annual change in voltage experience by end users and meets Benchmark Performance Thresholds. For ineligible projects the protocol provides guidance to evaluators for estimating reliable savings by ensuring key validity threats are addressed.
