Uncertain Policy Decisions and Investment Timing: Evidence from Small Hydropower PlantsAne Marte HeggedalNorwegian University of Science and Technology (NTNU) Kristin LinnerudCICERO Center for International Climate and Environmental Research - Oslo Stein-Erik FletenNorwegian University of Science and Technology (NTNU) October 21, 2011 Abstract: Based on panel data of 214 licenses to construct small hydropower plants, we examine whether uncertainty with respect to the introduction of a market for renewable energy certificates affected the timing of investments in Norway from 2001 to 2010. Using regression analysis, we find that (1) investors owning a portfolio of licenses act in accordance with a real options investment rule, and uncertain climate policy decisions delayed their investment rate; and (2) investors owning a single license act in accordance with a traditional net present value investment rule, focusing on the value of the immediate investment and ignoring policy uncertainty.
