Recovered Energy: Do not include energy recovered from the production process (e.g., waste heat, process byproducts) in the energy accounting of the EPI. The EPI’s underlying statistical model recognizes that plants have an opportunity to recover or self-produce a portion of the energy they require, and is adjusted based on plant characteristics and purchased energy inputs to the EPI.
Annual Cost: Total annual energy cost for each fuel type in current year dollars. Input of cost data is optional and does not impact the Energy Performance Score. This feature is provided for your convenience and use.
