Previously MERC has issued tariff orders for promoting many Renewable energy sources such as Wind, Small Hydro, Biomass, Co-generation etc. MERC released an approach paper on Renewable Portfolio Standards (RPS) considering Renewable Energy Sources in the state in an integrated and long-term manner. Prayas welcomed this approach and aggressive Renewable Purchase Standards for Distribution Companies (6% of total energy purchases in FY 09-10). Prayas also made some suggestions in order to make RPS effective and economically efficient such as re-determination of tariff for Wind Power projects.
