Determines the new required energy input to the process after efficiency improvements, accounting for the calculated fuel savings. This step provides the expected reduction in energy demand.

\begin{equation}\label{eq:pheic-new-energy-input} EI_{new} = EI_{current} \cdot \left(1 - \frac{FS}{100}\right)\end{equation}

\(EI_{new}\)	New energy input \([\unit{ \MMBtu\per\hour}]\)
\(EI_{current}\)	Current energy input \([\unit{ \MMBtu\per\hour}]\)
\(FS\)	Fuel savings \([\unit{ \percent}]\)
