AusAID Public Sector Linkages Program (PSLP) project, „Concentrating Solar Power in India‟. The report was commissioned by the Australian Government Department of Climate Change and Energy Efficiency (DCCEE) with the cooperation of the Government of India Ministry for New and Renewable Energy (MNRE). The aim of this report is to analyse the context, barriers and policy options for the growth of the Concentrating Solar Power (CSP) industry in India, for use by government policy and program implementation staff in both countries. It may also be of interest to others such as CSP developers and investors. Global status of CSP CSP technologies use systems of mirrored concentrators to focus direct beam solar radiation to receivers that convert the energy to high temperature for power generation. There are four main configurations that are commercially available - Parabolic Trough, Linear Fresnel, Paraboloidal Dish and Central Receiver. Typically, this heat is transformed to mechanical energy through a steam turbine and then into electricity. CSP has advantages compared to photovoltaics as it can readily incorporate thermal energy storage and/or fossil fuel boosting to provide dispatchable power. The use of relatively „low tech‟ manufacturing methods for solar collector fields, together with the use of steam turbine technologies adapted from the existing thermal power generation industry, makes the prospect of continued, rapid scale-up of CSP capacity very feasible. Key features and status of the four main CSP technologies are summarised below.

Since 2005, CSP project activities have recommenced and gained considerable momentum. The CSP sector is widely forecast to continue to grow at very high rates. This growth has been mainly in Spain and now increasingly in south-western USA and is linked to Feed-in Tariffs and Renewable Portfolio Obligations in those jurisdictions. 5 Concentrating Solar Power in India The International Energy Agency‟s Solar Power and Chemical Energy Systems (SolarPACES) program is the umbrella under which the CSP community has worked together and shared information for many years, (see http://solarpaces.org/).
