Aiming to net-zero emissions, hybrid power generation through renewable means has gained substantial attention across the globe. Considering the stochastic nature of renewable energy resources, a comprehensive performance assessment is a must prior to project development. Present work is a novel multidimensional 6E analysis (energy, exergy, economic, environmental, advanced exergy, and exergoeconomic) to evaluate the performance of hybrid wind-solar energy systems. The analysis is performed using long-tern (41 years) high-resolution ERA5 reanalysis resource data and the mathematical modeling by means of MATLAB R2018a computation software. The long-term data facilitates reliable and precise predictions of resource availability, power generation, and system performance during the lifespan of the project. The performance of HWSES in terms of capacity factor and exergy efficiency is computed to be 9.6–35.5% and 4.7–10.4% respectively, whereas the extended exergy efficiency lies in the range of 3.39–5.79%. Hybridizing wind power projects with solar power enhances the overall system capacity factor, exergy efficiency, and extended exergy efficiency by 3.46%, 5.12%, and 2.87% respectively. Hence, the hybridization leads to superior year-round system performance with smaller power fluctuations than the standalone systems. Further, wind, solar and hybrid systems would annually reduce the Specific Emission Reduction of 1128 tone/kW, 1685 tone/kW, and 1407tone/kW respectively. The present research will be helpful to the policy-makers and the project developers in the project feasibility study of hybrid energy systems.

“…According to income tax law, companies engaged in renewable energy such as solar and wind were provided with accelerated depreciation (AD) on a written down value (WDV) basis at 100% in the 1990s later revised to 80% in 2002 and 40% in 2017 (NRDC and CEEW 2014 ; Das et al 2021 ). The AD program can be termed as a major incentive for new project developments (Kumar et al 2019 ).…”

Graphical abstract The Indian renewable energy sector has grown at a compounded annual growth rate of 15.51% in the last five years, where wind growth is about 8%. The Indian government has been adopting changes to create a safe, cheap, and sustainable energy system to fuel vigorous economic growth. The government has made significant efforts in ensuring universal access to energy, giving power to its residents. It is implementing a large-scale deployment of renewable energy, particularly solar and wind. This paper examines the country's wind sector in-depth, including the government policy, financial incentives, and accomplishments. The study goes on to discuss the prospects and problems of the wind sector, as well as solutions to overcome them to reach the estimated target of 140–150 GW by 2030. Wind power growth in the country has weakened in the last few years which may hamper the country’s ambitious renewable energy targets. Wind industry is facing several hindrances ranging from discontinuation of incentives, land acquisition, DISCOM’s poor health, change in bidding scheme, old wind sites, etc. Certain steps, such as repowering outdated wind farms, giving generation-based incentives, tax concessions, reassessing the country’s wind potential, and constructing competitive renewable energy zones could aid in reviving the wind energy sector.
