The past term has witnessed impressive worldwide dynamic growth of CSP plants led by Spain and the US, and rapid parallel growth in SolarPACES membership, from 12 to 20 member countries. This increased strength helped reinforce our worldwide dissemination activities, most visibly in this year’s 17th SolarPACES Symposium, which is expected to have an attendance of nearly 1000. We are very pleased to see how this traditional event has grown in response to the increasing need for an independent platform where experts from R&D, industry, policy and financing can meet. Maintaining and increasing the impact and quality of the SolarPACES Symposium will be one of the high priority tasks in the upcoming five-year term starting in 2012. Global power supply has risen significantly in the political agenda of many countries as a consequence of the tragic Fukushima accident last March. Renewable Energies in general had already achieved a significant share in the overall energy mix in many countries, and this trend seems to have received stronger political support since then. As the shares of fluctuating renewable sources increase, the ability of each technology to match demand is of growing importance, and concentrating solar technologies, with their specific potential to provide short- term (thermal/power) and long-term chemical storage, have a lot to contribute to the optimal integration of the largest renewable source of clean, sustainable and affordable energy still to be tapped, the sun. Against this background in the coming term, an even stronger SolarPACES will focus on the internationally coordinated development and deployment of concentrating solar technologies to further reduce cost, increase dispatchability, and reinforce awareness of the benefits of CST. While we are still heading in the same direction, personal changes are sometimes unavoidable. We want to express our most heartfelt gratitude to our former Chairman, Dr. Thomas Mancini of Sandia National Laboratories, who resigned as Chairman in April 2011, after serving SolarPACES for seven years in this capacity (and many more years as Operating Agent). We are all indebted to Tom Mancini’s dedicated effort to the progress and development of the SolarPACES Implementing Agreement. The growing SolarPACES community will stay in close touch and wishes him a sunny retirement. As we are now looking forward to the election of a new Chairman in the autumn ExCo Meeting, we would also like to express our gratitude to the continuing Operating Agents and ExCo Members of SolarPACES for their dedication to our common goals, and hope to keep on working with this great team in the future. , Robert Pitz-Paal Christoph Richter Acting Chair Executive Secretary iv ANNUAL REPORT 2010 SOLARPACES SOLARPACES TABLE OF CONTENTS v Table of Contents Page FOREWORD R.
