Impacts of Climate Change and Variability on the Subarctic Hydropower Sector

The sub-arctic regions of North America and Eurasia are rich in hydropower resources, yet vulnerable to variability in climate processes. Southeast Alaska and Norway share similarities in the complexity of terrain, fjord geography, and the prevalence of isolated microclimates. This presentation describes the results of several studies of the impacts of historical climate variability and projected climate change on the supply, demand, and price of hydropower in the Sub-Arctic. The potential role of climate prediction tools for mitigating impacts on various time scales is also discussed. Finally, the author describes using the results of the study to plan design criteria for new infrastructure.
