A Regulator’s Guidebook: Calculating the Benefits and Costs of Distributed Solar Generation

As distributed solar generation (DSG) system prices continue to fall and this energy resource becomes more accessible thanks to financing options and regulatory programs, regulators, utilities and other stakeholders are increasingly interested in investigating DSG benefits and costs.

This seminal report highlights lessons learned from 16 regional and utility-specific distributed solar generation (DSG) studies, summarized in a review by the Rocky Mountain Institute (RMI). A standardized valuation methodology for public utility commissions to consider implementing in future studies is also included.
