Contract payments negotiated with Energy Services Companies (ESCO) are often based on projected energy cost savings. The contract payments may be fixed from year to year or may include an escalation clause that increases them annually over the duration of the contract term (performance period). The portion of the contract payments that is based on projected energy savings should be escalated at the energy price escalation rates projected by the Energy Information Administration (EIA) of the U.S. Department of Energy. A DOE/NIST computer program, Energy Escalation Rate Calculator (EERC), calculates an average annual escalation rate based on the EIA projections and weighted by the proportion of energy savings coming from each of the fuels used in the project. The calculator is updated annually with the latest EIA energy price projections, which are also embedded in the BLCC programs and in the discount factor tables of the Annual Supplement to Handbook 135. EERC can be accessed from the DOE/FEMP web site at http://energy.gov/eere/femp/building-life-cycle-cost-programs.
