A review of wind energy developments in India
Climate change, dwindling reserves of fossil fuels and shortage of electricity have prompted the government to give an impetus to renewable energy sources. Wind energy, with an average growth rate of 30%, is the fastest growing source of renewable energy in the world. India has a potential capacity of over 45,000 MW out of which 1869 MW has been extracted from this eco-friendly source. India ...

Vortex identification for the study of atmospheric flow: a new vortex criterion applied to wind resource assessment
Vortex identification is a non-consensual point of discussion among fluid mechanics researchers. Classical criteria such as Q and delta are hereby confronted with a new definition. A pertinent task for wind power project development studies is the post-processing analysis of the wind resource simulations in order to improve the project design. There is a large interest in extracting more ...

Vortex identification in wind resource assessment: Application of a new vortex criterion for an improved wind resource analysis
A pertinent task during wind power project development studies is the post-processing analysis of the wind resource simulation results. There is widespread interest in extracting more information from typical commercial software – like WindSim, OpenWind, Meteodyn, WAsP – at a minimal cost during the prospection and/or the development stage of some wind power project. The current paper ...

Analysis of vertical wind shear in the Southern Great Plains and potential impacts on estimation of wind energy production
This paper describes the analysis of near-surface wind speeds in Western Oklahoma. The goals of this research are to characterise the nocturnal low-level jet (LLJ) in the region, and to assess the impact wind variability, vertical shear and the LLJ on wind energy calculations. Results show the seasonal variability in wind characteristics as well as in the vertical wind shear, and also illustrate ...

What is the Impact of Seabed Conditions?
Eirik Byklum, Statoil, has commented that: “developers have learnt the hard way that poor conditions on the sea bed can have a very negative impact – they are much more aware of this and its cost implications” How important are seabed conditions for your offshore wind business? Alongside distance to shore, water depth, and wind conditions, seabed consistency has a major ...

On the probabilistic distribution of wind speeds: theoretical development and comparison with data
The probabilistic distributions of wind speed are a critical piece of information needed in the assessment of wind-energy potential, and have been conventionally described by various empirical correlations. Among the empirical correlations, the Weibull distribution has been most popular due to its ability to fit most accurately the variety of wind-speed data measured at different geographical ...

Multi-megawatt wind turbines for offshore use: aspects of Life Cycle Assessment
Life Cycle Assessment (LCA) is an instrument to quantify environmental impacts of the entire energy supply chain. According to the LCA, an appropriate indicator system should comprise all steps of a system's life cycle: production, operational and disposal processes ("cradle-to-grave"). Cumulative Energy Demand (CED) might be seen as one part of LCA as far as the depletion of energy resources in ...

Estimation of capacity credit for wind power in Libya
This paper presents the results of a study that evaluated the wind potential at the central region of the Libyan coast and estimated the capacity credit of wind power in the national network. Several sites were investigated to choose the most suitable sites for wind farm establishment. Different sizes of Wind Energy Converter Systems (WECSs) were selected to estimate the wind potential. The sizes ...

How to Keep Your SymphoniePRO Data Secure
Data matters. The accuracy, consistency, and yes, safety of measurement data keep many wind developers and analysts up at night. Customers often ask about the digital and physical security of RNRG instruments, so I sat down with Michael Fisher, product manager for our wind resource assessment (WRA) line, to get answers to the most common questions. Q: Why is data security important? Michael: ...

Comparative life cycle assessment of 2.0 MW wind turbines
Wind turbines produce energy with virtually no emissions, however, there are environmental impacts associated with their manufacture, installation, and end of life. The work presented examines life cycle environmental impacts of two 2.0 MW wind turbines. Manufacturing, transport, installation, maintenance, and end of life have been considered for both models and are compared using the ReCiPe 2008 ...

Using Lidar for WRA Campaigns: Your Questions Answered (Part I)
In the course of conversations with wind developers new to Lidar technology, a number of questions seem to come up regularly. In this and future blog posts, I will attempt to answer these questions in some detail to benefit others who might be pondering them as well. Two very practical questions have to do with how WINDCUBE® Lidars might affect overall wind resource assessment (WRA) campaign ...

Life cycle assessment of a 150 MW offshore wind turbine farm at Nysted/Roedsand, Denmark
The purpose of this life cycle assessment (LCA) was to illuminate and describe the potential environmental impacts caused by an offshore wind turbine farm (WTF) throughout its lifetime and use this knowledge in the planning and improvement of future WTFs. The LCA was based on experience from the LCA on Danish electricity and district heating [1] as well as the offshore WTF project at ...

An integrated assessment for wind energy in Lake Michigan coastal counties
The benefits and challenges of onshore and offshore wind energy development were assessed for a four‐county area of coastal Michigan. Economic, social, environmental, and spatial dimensions were considered. The coastal counties have suitable wind resources for energy development which could contribute toward Michigan's ten percent renewable energy standard. Wind energy is cost‐effective with ...

Environmental impacts of integrating wind energy systems and supplemental energy generation and storage systems
Wind energy systems offer a promising alternative energy source due to the environmental, economic, and social benefits and, as a result, have garnered support for development and implementation. One of the major drawbacks of wind energy, however, is its variability due to the stochastic nature of wind, thus, supplemental energy generation or storage technologies are required. In this study, a ...

Reducing avian collisions with wind turbines
Wind is an important renewable energy source for Europe. The wind power capacity installed in 2014 could produce enough electricity to meet over 10% of the EU’s electricity consumption. However, wind power structures can also be harmful to birds, which can collide with turbines. This study assessed methods of reducing avian collisions with wind turbines and makes several practical ...

Measuring Offshore Wind Resources
To select the right offshore wind site, estimate the future energy output of a wind farm, and determine the best layout for the turbines, project developers must conduct wind resource assessment (WRA) campaigns on site. This is a critical phase of the successful development of wind farms. WRA campaigns on terrestrial sites have traditionally been performed using meteorological towers equipped ...
