A power plant can cost hundreds of millions of dollars. To pay Acme Construction, Power Holdings receives financing from a development bank and a commercial bank. These banks provide a guarantee to Acme Construction's financier that the company can pay for the completion of construction. Payment for construction is generally paid as such: 10% up front, 10% midway through construction, 10% shortly before completion, and 70% upon transfer of title to Power Holdings, which becomes the owner of the power plant.
