Tariff Structure and Tariff Adjustment Mechanism for Managing Risks in PPP Hydropower Projects
Public-Private Partnerships (PPP) has been applied widely in infrastructure development worldwide.Among them, hydropower projects are generally large at scale with huge investments and last for a much long period. There are therefore many risks including some special risks such as the flow-rate risk, i.e. the risk that the rivers runoff capacity is not enough for a hydropower project to generate power, associated with PPP hydropower projects. In general, the revenue of a PPP hydropower project is generated by selling electricity to the government while the latter sells to end-users as power grid is usually controlled by the public in most countries. The design of tariff adjustment mechanism is hence very important for fair risk allocation between the public and the private sectors especially the flow-rate risk. This paper firstly identifies, analyzes and allocates various critical risks in PPP hydropower projects based on a public- private win-win principle, and then proposes a procedure for the design of electricity tariff adjustment mechanism in the Power Purchase Agreement (PPA). A PPP hydropower project case will also be employed to demonstrate the procedures.
