• Comprehensive review on individual and hybrid wind-solar energy policy. • Evolution and current status of Indian wind and solar energy policy framework. • Techno-economic parameters for the hybridization of wind and solar power projects. • Barriers and recommendation regarding renewable energy policies. Wind and solar energy are currently the most prominent and reliable sources of renewable energy. Wind and solar power deployment largely depend on government policies and have a specific policy and regulatory provisions. The declaration of hybrid wind–solar policy has changed the dynamics of individual wind and solar power projects by introducing the scope for developing hybrid power projects to harness wind and solar energy simultaneously. The techno-economic structure and the existing scenarios of the fractional contribution of wind and solar sectors are going to play an important role in the development of hybrid power projects. This paper aims to present a comprehensive review of the impact of the existing individual wind and solar energy policies along with the recently declared hybrid policy in India and how this hybrid policy will affect the techno-economic structure of the existing and new power projects. Further, various kind of barriers faced by project developers while establishing renewable energy-based power projects and recommendations which can be practically implemented have been elaborated to facilitate and achieve the faster deployment of wind and solar power generation.

This paper is an enquiry into the role of State policies in influencing wind installed capacity. The paper studies the impact of policies on deployment of wind potential across the States of India over two decades. Aggregate indices are computed for each of the seven wind resourceful States of India indicating attractiveness for installed capacity of wind energy. For computing the indices, four policies, Feed-in-Tariff, Renewable Purchase Obligation, Banking facility, and Wheeling charges are considered. Panel data techniques are then employed to investigate the impact of the policy differences on wind potential deployment over the 19 year period (1993–2012) after controlling for three State-specific factors. The controlling factors include per-capita income of the State, power deficit, and ratio of installed capacity of wind to geographic potential indicating unmet capacity. The results show that that policy index positively impacts wind deployment whether control variables are included or not. Moreover, the control factors like the per-capita income of the State and unmet capacity have positive influence over the investment in wind energy. [ABSTRACT FROM AUTHOR]

Renewable energy can play a strategic role in India in meeting the country’s growing energy demands, as well as combating climate change. Policymakers have recognized this potential and over the last decade have intensified their efforts towards creating a conducive regulatory and policy framework. Policy instruments such as renewable obligations, feed-in-tariffs and generation based incentives have specially aided the transformation towards large scale generation, enabling higher efficiency and lower costs of generation. However, financing has emerged as a significant barrier for sustaining the momentum gained in recent years. Given this background this paper provides an overview on the evolution of large scale generation and the consequent changes in financing requirements. It further reviews the emerging trends and barriers in the financing landscape and analyses the impact of policy performance in this context. Finally, it considers the design of a national renewable finance framework complete with targeted finance push instruments that can complement existing demand pull policies in facilitating investment.

Abstract: Indian wind energy sector has seen a CAGR of more than 27% during the period 2002–2007. However, the annual capacity additions has been declining for the past 2 years and recently, India lost one place in the Global ranking on total installed wind capacity to China. While issues like unfavourable tariff, non-uniform state policies, unavailability of evacuation infrastructure, etc. can be attributed to the slower pace of capacity addition, the issue of unavailability of on-shore wind sites with sufficiently high wind velocity is expected to take centre stage in the next 2–3 years. Wind sites with low wind velocity make the investment unattractive to developers. Given the current situation, repowering as an investment option, which has already seen favourable response in countries like Germany and Denmark, would start maturing in India. This paper analyzes the present situation of the wind energy in India, evaluates the different wind energy market segments including repowering market, provides financial highlights of the repowering concept and ends with concluding remarks on major triggers which can set this concept in motion.
