Used and Useful Principle: Still Relevant in Utah
The Utah Bar Journal
Within the framework of revenue requirement regulation, the principle of used and useful appears to have been somewhat forgotten in today’s world of least cost planning and future test periods. However, the used and useful principle has a relatively long history in the regulation of electric utilities and there is little, if anything, to suggest that it has been legally overruled in Utah.
