摘要：Majority of power generation plants in India depends on non-renewable resource as a fuel due to low cost and ready availability. Usage of non-renewable resources for power generation on the other hand is expensive and less reliable. If focus is on a single source of renewable energy then the statement stands true. Studies however, shows if two or more renewable energies are used together in hybrid mode, system becomes efficient. Present study focuses on a geothermal power plant located in India, which was experiencing reduction in power generation. The plant employs Organic Rankine Cycle. In order to increase power output and to make system efficient, an interesting match was noticed between solar thermal and geothermal. The two energy producing techniques differ in heat collecting but share the same power island structure. Various solar thermal collectors were analyzed for the retrofit. The best match in evacuated tubes was found for the system. The collectors were retrofitted, used in a hybrid mode and with the utilization of ORC, electricity generation was analyzed. The annualized electricity generation was estimated using the seasonal parametric investigations. The present study discusses about the electricity generation from the hybrid solar geothermal setup of capacity up to 35 kW.
