expenses were quantified, and then the model was run with 15 megawatts ("MW") of load added

base-plus-15-MW run was divided by the difference in megawatt-hours to produce a marginal cost
of energy.Id. at 7-8.

and time-differentiated marginal costs are included as Attachment 3 to the Application, and that to
