RE: 2007Idaho Energy PIan Policy E-18
Rocky Mountain Power has prepared its Power Content Label or "fuel mix" report for 2018 in
compliance with Policy E-18 of the 2007ldaho Energy Plan. The policy states: "Idaho utilities
shall report annually to their retail customers their sources of electricity (their "fuel mix")". The
Company's Power Content Label is based on energy for reporting consistency in all jurisdictions.
Rocky Mountain Power's Power Content Label detailing electricity sources will be sent to the
Company's Idaho retail customers as a bill stuffer during the April billing cycle, April 3 through
May 1, 2019. A copy of the bill stuffer is enclosed with this letter.
Please contact me at (801 ) 220-2963 if you have any questions or require further information.

Fuel mix definitions
Coal generation uses coal as the primary fuel source,
Natural gas Seneration uses natural gas as the
primary fuel source.
Hydroelectric generation is created when water
flows from a higher elevation to a lower elevation,
and the flow is converted to electricity.
Wind generation is created by movement of air:
Biomass generation is from burning solid organic
fuels from wood, forest or field residue, or dedicated
energy croPs.
Geothermal generation comes from thermal energy
naturally produced within the earth.
Solar generation uses the heat from the sun.
