consider regional scale changes that may affect energy supply and demand in the state. This talk will review a set of the climate model simulations over the 21st century and how California’s climate would be affected, with attention toward the rates and magnitude of warming, its seasonality, the occurrence of heat waves, and how precipitation may be affected
Dan Cayan is heading up the PEIR efforts to understand how climate change will impact California resources and ecosystems. This work is using GCM simulations, a large set of historical observations, and much finer scale regional models to help us understand how climate change will occur over the California landscape.

Climate Change and Electricity Demand Maximilian Auffhammer, UC Berkeley
Prof. Max Auffhammer will give a presentation regarding his research on impacts of extreme heat days in California on peak electricity demand due to a rapidly increasing population and a resulting increase in energy demand. His analysis uses atmosphere- ocean general circulation models and simulated projections of temperature over the coming century. The relationship between high temperature and electricity demand for air-conditioning, presents future challenges when population and income growth are taken into account.

Introduction: Impacts of Climate Change in Low and High Elevation Hydropower John Dracup, UC Berkeley
Low and high elevation reservoirs will be impacted by climate change – flow timing may change, flow variability may change and energy prices may be affected. The size of these impacts will depend on how well operators manage changes in the hydrograph timing. This in turn depends on the size of reservoir storage and the degree of flexibility in system operations. In this introductory talk, Prof. Dracup will discuss these issues and other factors that influence the impacts of climate change on hydropower generation in California.

Case studies in American and Merced River Basins Larry Dale, Lawrence Berkeley National Laboratory
Dr. Dale will present two case studies of the impacts of climate change on hydropower generation in California. The first case study focuses on a high elevation system, the Upper American River Project operated by Sacramento Municipal Utility District (SMUD). This study indicates that hydropower generation is closely related to the changes in reservoir inflows and the ability of operators to maintain high summer period storage levels. The second case study focuses on a low elevation system in the
