there was a significant decline in costs on a $/kW basis from the 7 MW system to the 20 MW system. The overall decreases in costs can be attributed to a decline in the component costs and construction cost savings for the balance of plant. As previously noted, costs are developed using a consistent methodology that includes a broad project
