“Integrating Renewable Energy System: Repowering Project”

Delightful of massive activities and goals to develop energy management of the following organization/agency: Global Wind Energy Council (GWEC), United Nations Framework Convention on Climate Change (UNFCCC), International Energy Agency (IEA), International Renewable Energy Agency (IRENA), and Renewables Global Status Report (REN21).

The key to today’s need of sustainable energy challenges to ensure the wind power technology which they announced specifically was established with their economic benefits of low cost schemes. Nowadays, in the wind energy sector, assessing the technical and economical calculations for the repowering of wind farms are increased at various countries such as European, India, China, and United States. The roles of GWEC were developed over 1,500 companies, institutions, and organizations worldwide (80 countries). Their team assisted to implement the wind energy productions with the following ideas of manufacturer, developer, spare part suppliers, research institutes, renewable associations, finance companies and insurance policies. International and national organization/agencies are interested to benefit through the wind power productions.

Wind Project Plan and its Pathway:

Wind energy technology is estimated to become a supportive and backbone of the future renewable energy system. Modern life style is required for more electricity in various perspectives, new way of life looking for natural resources and their renewable energy system. Although, it accounts for approximately 10% of electricity production capacity globally, now it has a leading market share in some pioneering countries [1,2]. In Denmark, scientific team have suggested with the physical space factor of only 67% in its capacity for repowering wind projects and in additional factors (drive repowering, development principles, and political bargaining factors) were also included.

At present, only a very few countries are aware about the wind energy and fleets activities to support substantial repowering projects [2]. Denmark is a prime case for wind energy progress with their analysis, and emerging theme as the major electricity production technology. They have an increasing trend market share and reached 47% in 2019 [3], which features the very old wind energy (turbine fleet) in the world [1,4]. Scientist have proposed with interesting information and their perspective on repowering projects and their comprehensive market share significance.

During this approach of multifaceted drivers for repowering decisions with data collection (municipal area, geospatial analysis, projects) are:

To identify dismantled wind turbines which are situated at the same located site as the new project (on-site) as well as existing wind turbines in different locations that require dismantling, so that new wind turbines can be installed.
To identify categories for dismantling reasons in proper repowering planned projects, specifically for those wind turbines physically situated in the outside area at a notable immediate project development site (off-side).

Based on data collection, project peoples are covering (91%) percentage of all dismantled capacity in repowering projects and dismantling reasons. They have notable variations between the traditional plans (on-site) and developed repowering project plans perspective. Recent attractive scenario (from 2012 to 2019) and newly developed repowering (wind energy turbine) projects were around 102 projects.

Tianguang et al., reported on a selective and collective research report entitled, “India’s potential for integrating solar and on- and off- shore wind power into its energy system” from various research institutions such as China and USA [5].

Figure 1. Regional distribution of capacities inferred for future 2040 with Coal, Gas, Solar, Wind project and energy storage [5].

The primary need of energy supply is an increasing trend in developing India. An Indian research report 2017, have stated that the 3^rd rank globally with the emission of Carbon dioxide (2.5 Gt) on its another side. Utilized coal accountability or energy supply in India, have stated that the following percentages (58%) in research report 2015 and is also projected to future percentage (42-50%) by 2047. The demand for energy system or electricity is expected to be increased in India. The power generation amounted to 344 GW (in 2018) of which capacity factor of sources [coal (57%), hydro (14%), wind (10%), gas (7%), solar (6%), biomass (3%) and nuclear (2%)]. The term Capacity Factor (CF) is defined as “The fraction of power generated by a particular facility relative to its nameplate potential”. Future plan has to develop the intermittent nature of the energy source for the above mentioned sources. The total power consumed in 2018 from Renewables energy accounted for < 7.6% (1.3 PWh). A step-down capacity from traditional (coal-ﬁred power) plants will look for an alternative with the optimal next generation mix and also economics system in the future.

Indian government implements the new policy (NITI Aayog scheme), with a target of renewable capacity of (175GW) for 2022. In addition, wind or solar project plan response with 160GW. Hence, future energy sector in an Indian power project targeted towards a new renewable pathways and to decarbonize the environment.

Emerging Indian Power Economy:

Utilizing a optimization model, power demand is predicted to be more in future by renewables, solar and wind project sectors, which may alert the coal source with low cost scheme. The ancillary advantage of model would be an important reduction in power sector related to emissions of CO₂. Dual benefitted model, in which cost of project for solar (Photovoltaic cells) and wind turbines systems are accepted in current decreasing trend.

Tianguang et al, analyzed the offshore filter, onshore filter, solar filter, regional power capacity, power generation, and also projecting the Indian energy system covering ﬁve sector/regions (East, West, North, South, and Northeast), calculating for regionally distributed power plants (hydro, thermal, and nuclear), new model renewables (solar and wind project in onshore/offshore), energy storage systems for the inter-regional energy power grid.

The researcher suggested that 80% of projected 2040 energy/power need could research result with a reduction (85%) in emission of CO₂. Hence, chapter of coal source utilized in power sector might be dominated track via renewable, solar and wind projects.

Our SNB team emphasize this research article to enrich our viewers knowledge on the future perspectives of wind and solar projects. In denmark projects, the authorization of repowering as a negotiated one during the process between host researcher communities and wind plan developers. It will be possibly hard to unlock the overall potential of new wind energy plan in the future. Insights of future, Indian power plan is an alternative source of coal projects via optimization model, which is more attentive in gaining energy and emission of CO₂. It also shows the new challenges and future opportunities obtained by repowering as a means to enhance renewable energy plan production. We hope newly designed methodologies are always welcome in scientific scenarios with eco-friendly, green energy and sustainability of energy concepts. Hence, scientific community will give a proper direction for affordable life style with wind turbine and solar energy parks.
