The BSC component satisfies the steam demand from the PA and BLD Components. In some industries, the PA Component produces byproducts that are consumed in the BSC Component. The iron and steel, paper, and aluminum industries determine boiler and CHP use within the PA step.
The IDM base year is currently 2014, which is the year of the latest available Manufacturing Energy Consumption Survey (MECS) [2]. EIA conducts the MECS every four years. No model results are available before the base year. The base year is periodically updated as new MECS become available.
Petroleum refining (NAICS 32411) is not modeled in the IDM. Refining energy consumption is modeled in detail in the LFMM module of NEMS, and the projected energy consumption is reported in the manufacturing total. In addition, projections of lease and plant fuel, energy used for liquefaction of natural gas, and fuels consumed in cogeneration in the oil and natural gas extraction industry (NAICS 211) are not calculated within the IDM. They are calculated in other modules.
