The Energy Escalation Rate Calculator (EERC) computes an average annual escalation rate for a specified time period, which can be used as an escalation rate for contract payments in energy savings performance contracts and utility energy services contracts. Escalation rates can be computed based on the Energy Information Administration (EIA) energy price projections used for calculating the Federal Energy Management Program (FEMP) discount factors and on EIA projections adjusted by NIST for potential carbon pricing.
