The PPP model serves as a risk-adjusted estimate of the cost of procuring the project as a PPP. The Government Entity must ensure that the underlying base costs in the BCM reflect the costs to government of providing the services to the same specification as expected from the private sector. In addition, it will include PPP-specific financing costs, such as the cost of debt and equity, define a target equity internal rate of return ("IRR"), and solve for the project IRR, which will then be used to compare different scenarios.
