How rapidly will or could demand for power grow in Vietnam? What will interest rates be? Will the cost of generating plants go up or down, and by how much? What will the cost of each fuel be? Will the cost of carbon or other pollution begin to enter into investment decisions?
This paper will examine these questions. It will begin by looking at demand projections and investments in efficiency – getting more output per kilowatt hour used. It will then try to estimate the costs of building and running various types of generating plants in Vietnam over time. It will also use various costs of carbon to see if including these both as a source of global warming and as an indicator of local pollution changes the calculation. Changes in the domestic supply of gas will also influence the set of potential solutions, as will the declining costs of solar electricity and battery storage. In all of this it is the system or mix of investments that need to work, not any single investment.
