Wind is a powerful and renewable source of energy that flows in every corner of the surface of the planet. As the world moves towards renewable and alternate energy sources, the potential of wind energy has been recognized and methods to use it to its maximum potential are being explored. India has been harnessing wind power over the years, but only lately, it has sent an ambitious target of achieving 60 gigawatts (GW) of wind installed capacity by 2022. The government has issued several tenders to invite private players or Independent Power Producers (IPPs) to develop wind energy projects. Many foreign investors and the Private Equity players have shown interest in investing in this growing renewable energy (RE) market in India. However, developing a wind project comes with lot many challenges as compared to any other RE project. These challenges range from land availability to seeking grid connectivity approvals and evacuation of the power. Along with this, the current reverse bidding process for the tariffs, have made the per unit tariffs to cost as low as INR 2.4. Hence, it is important to consider the technical and commercial feasibility of the project to function at these tariffs. This paper studies the current scenario of wind energy in the Indian market and analysis the potential for the development of wind projects. It also analyses the technical and commercial feasibility of the project by assuming a 300 MW project, having INR 2.5 as tariff, using Wind Resource Assessment (WRA) and Financial Model.

Offshore wind energy has been identified as one of the most promising and increasingly attractive sources of energy. This technology offers a long-term power-generation source, less environmental impact, and fewer physical restrictions. However, given the complexity of this technology, economic feasibility studies are essential. Thus, this study aims to identify the main trends and criteria or the methods used in the economic feasibility studies of offshore wind energy, providing a review of the state of the art in this literature. For this, a Systematic Literature Review was carried out. The article shows the growing interest in offshore wind power generation and highlights how recently the interest in the studies that assess the technical–economic feasibility of this source has grown; it presents the main milestones of the topic. Based on a structured literature review, this article identifies the main trends in this topic: (i) wind farms, (ii) risk, (iii) floating offshore wind farms, (iv) decommissioning and repowering, (v) net present value, (vi) life cycle cost, and (vii) multi-criteria decision-making; it provides a broad view of the methodological possibilities and specificities for investors and researchers interested in conducting studies on the economic feasibility of offshore wind generation. In addition, finally, a research agenda is proposed.

With the negative climate impact of fossil fuel power generation and the requirement of global policy to shift towards a green mix of energy production, the investment in renewable energy is an opportunity in developing countries. However, poor economy associated with limited income, funds availability, and regulations governing project funding and development are key factors that challenge investors in the energy sector. Given the various power generation resources, including renewables, it is necessary to evaluate the possible power generation investment options from an economic perspective. To realize this objective, solar PV, wind and diesel power generations are economically compared, considering the incremental rate of return and incremental benefit to cost ratio techniques. The alternative investment options of distributed generation technologies are evaluated for Maharashtra, India under different depreciation methods, and the effect of the latter on selecting the best investment candidate is investigated. The paper also conducts sensitivity analysis to examine the impact of capital cost, operation and maintenance cost, and fuel cost variations on the selection decision considering a comparison of the different general projects’ cash flow structures discussed in the literature. The economic aspects of selecting a project among possible alternatives for an investment in the power sector are analyzed, and the presented review provides comprehensive comparisons with respect to the literature approaches. The results reveal that, in the benchmark case study, the PV project is rejected and disregarded from further comparisons with other candidate projects since its equity internal rate of return (10.25%) is less than the minimum accepted rate of return, leaving the selection between wind and diesel energy projects. The study reveals that the incremental rates of return under such a comparison are 37.88%, 45.94% and 37.50% when MACRS, declining balance and straight line depreciations techniques are applied, respectively. Thus, the wind energy project is the favored option in this case. For the economic assessment of other case studies, the application of both sensitivity analysis on the capital cost and operation and maintenance cost and literature approaches to structure the projects reveal that wind energy for Maharashtra, India is a more attractive and feasible option compared to other distribution generation projects, while diesel is only considered to be a good option when its fuel cost is reduced by 5%. Finally, the paper highlights policy implications that can influence the decision to move towards investment in distributed generation technologies as a future research direction.
