A malt plant is considering the installation of energy saving systems as part of an expansion plan for the plant. The cost of these systems amount to \$372,000 and the installation costs represent an additional $128,000. The projected fuel savings are \$50,000 per year for the first 10 years of operation, and $100,000 per year from years 11 through 20 , when the plant is expected to operate at full capacity.
