Energy Resilience Return on Investment
Businesses, governments at all levels, and emergency and health services are increasingly seeking ownership of their energy security. Systems that include generation, storage, and controls packages allow building owners to use their assets to generate cost savings or income during normal operations; at the same time, these systems can provide energy security in the event of power loss. Largely absent in the industry, however, are valid and reliable guidance and best practices for building owners who are installing an energy resilience system. There has been no single source of guidance for determining how much capital investment results in the most favorable economic return on an energy resilience system. This paper proposes the formulas and variables necessary for determining the best return on investment in energy resilience assets. It looks at generally accepted payback methods based on the time value of money. The calculation method presented here was designed to be applied across all use cases.
