Effectiveness of state incentives for promoting wind energy： A panel data examination

Frontiers in Energy 2015年第3期9卷 247-258页

作者： deepak SANGROYA Jogendra nayak Department of Management Studies Indian Institute of Technology IIT Roorkee Roorkee 247667 India

Over the last decade, India has started to concentrate earnestly on renewable energy. The Indian government, as well as different state governments, are adopting policy instruments such as feed in tariff, captive consumption, renewable purchase obligation and genera- tion based incentive etc. aimed at renewable energy development. This paper evaluates the effectiveness of state level incentives for the development of wind energy in India. Fixed effect panel data modelling technique of econometric analysis is used to analyse the data of 26 Indian states in 11 years. The results show that feed in tariff and captive consumption are the significant predictors of wind energy development. However, renewable purchase obligation does not affect wind energy significantly.
