Chapter 6: Theories of Model OperationThe goal of the IRP model is to test potential resources under a wide spectrum ofpossible future conditions. To do this, the model attempts to quantify uncertaintyaround a host of variables that make up the <strong>Cowlitz</strong> <strong>PUD</strong> power cost function.Roughly speaking, there are three major sources of uncertainty. They are:1) Fiscal: Examples of fiscal uncertainty that are captured in the modelinclude variability in the cost of capital and IPP financing rates,variability around plant capital costs and uncertainty around inflation.2) Physical: Physical uncertainty is arguably the most relevant to theDistrict. Examples that are modeled include loads, generation, fuelprices, power prices and market heat-rates. Oftentimes historicalrecords can be used to define the statistics around physical variables.3) Policy: Public policy and legislation has a measurable impact on theDistrict. Unlike physical fundamentals (like load or runoff) policy isinherently unpredictable. Given the impact legislation can have on thebottom line it is vital to account for the possibility of certain laws beingpassed. The principle lawmaking uncertainty addressed in the IRPmodel is concerned with possible CO2 emission legislation.This chapter will discuss the tools and methods used to measure the sources ofuncertainty discussed above.51
