An earnings-equivalence model helps utilities and regulators calculate appropriate returns for conservation investments.
Traditionally, utility shareholders and their utilities have a bias toward supply-side resources as opposed to demand-side reduction programs. Reductions in demand may result in excess supply-side resources that are likely to be excluded from rate base because they do not meet the “used and useful” standard. However, there is a solution: Allow energy utilities to benefit from earnings rewards for demand-side reduction. From an earnings perspective, such a solution would place demand-side alternatives on par with supply-side projects.
