Production Efficiency Analysis in Utility Companies Considering the Share of Renewable Energy in Electricity Generation

Abstract

In this study, we estimated production efficiency, including generation capacity and generation volume, from 2013 to 2022 for 72 U.S. utilities using the DEA intermediate approach. The companies were classified into three groups based on the ratio of electricity generation from renewable energy sources. A meta-frontier analysis was then conducted to examine disparities in production efficiency relative to the ratio of renewable energy generation.
