Benefit-Cost Analysis of Utility-Facing Grid Modernization Investments
Synapse prepared a Technical Brief that provides an overview of benefit-cost analysis techniques for reviewing utility proposals for grid modernization investments. The Brief is written for regulators, consumer advocates, and other stakeholders who seek to determine whether grid modernization proposals are in the public interest; especially proposals for utility-facing technologies that help advance reliability, resilience, advanced metering, and the integration of distributed energy resources. The Technical Brief addresses some of the most challenging aspects of benefit-cost analysis for grid modernization, such as determining the appropriate cost-effectiveness test to use, accounting for interactive effects between grid modernization components, and accounting for qualitative benefits. Tim Woolf presented the material in a training course for consumer advocates at the meeting of National Association of Utility Consumer Advocates in November 2018. He also presented the material at the Mid-Atlantic Distribution Systems and Planning Training with the NARUC-NASEO Task Force on Comprehensive Electricity Planning on March 8, 2019. The technical brief was published in February 2021.
