Given the technological advancements of the Delta over the Matrix, Davidson expected that he could achieve significant savings in both labor and electricity costs. For labor, in the first year, Davidson forecasted a 10 percent cost reduction (the existing rate was $30 per hour), based on a 35-hour week in a 50-week year. This labor-saving would then increase by a fixed $250 each year. For electricity, in the first year, the saving was expected to be 10 percent as well. Electricity costs averaged $5.625 per hour, 24 hours a day, seven days a week, in a 50-week year. This electricity saving would then increase by a fixed $75 each year.
