The Toolkit outlines best practice techniques for assessing wind resource potentials as a foundation for a wind resource assessment. The wind resource assessment entails industry-accepted guidelines for planning and conducting a wind resource measurement program to support a wind energy feasibility initiative. These guidelines do not embody every single potential technique of conducting a quality wind measurement program, but they address the most essential elements based on field-proven experience.
The scope of the Toolkit covers:
- Wind resource assessment 101
- Sitting of monitoring systems
- Measurement parameters and monitoring instruments
- Installation of monitoring stations
- Site operation and maintenance
- Data collection and management
- Data validation
- Data processing
- Comparison of observed wind data with historical norm
- Wind flow modelling
The first wind turbines for electricity generation were developed at the beginning of the 20th century. Thus, wind technology is one of the most mature and proven technologies on the market. In 2015, the wind energy industry installed 12.8 GW in the EU – more than gas and coal combined. Globally, the current wind power installation capacity has reached 435GW with a significant growth rate of 16.4% in 2014 and 17.2% in 2015.
Wind turbines offer the prospects of cost efficient generation of electricity and fast return on investment. The economic feasibility of wind turbines depends primarily on the wind speed. Usually, the greater the long term annual average wind speed, the more electricity will be generated and the faster the investment will pay back. However, it is important to access the wind power potential (WPP) at any prospective location to decide the capacity of wind resource for electricity generation within available time limits of wind duration. Hence, it is relevant to observe the wind characteristics and type of wind turbine technology suitable for any given promising location. These factors are very much helpful for wind power developers and investors to make a decision with respect to the economic constraints.

The result of the UK referendum over EU membership has potentially huge implications for renewable energy. Perhaps the most significant of these is the UK may no longer be in the EU Internal Energy Market (IEM).
Completion of the EU’s internal market requires the removal of obstacles and trade barriers; the approximation of tax and pricing policies and measures in respect of norms and standards; and environmental and safety regulations. The objective of these is to help create a functioning market with fair access and a high level of consumer protection as well as adequate levels of interconnection and generation capacity. The IEM has led to the development of interconnections, to help reduce isolation of Member States from the European gas and electricity grids. Being part of energy union would have provided a huge market for UK renewables, such as its growing offshore wind fleet. Furthermore, it would have benefited energy security as renewable generation increases its overall share in the grid, through smoothing of generation variability.
The National Grid are certainly fearful of an exit from the IEM, with a spokeswoman saying: “It is vital the UK retains access to the IEM, which provides stability for energy companies and helps keep household bills down…UK energy security depends on gas and electricity from the IEM and it is essential therefore that we take no risks with that. The issue of energy needs to be treated with the highest importance by the government as the negotiations on Britain’s exit begin.”
Key players and commenters in the sector are almost unanimously giving a negative outlook as a result of the leave vote. These include factors such as higher costs, consumer impacts and a likely reduction in funding of scientific research; but the result is perhaps best summed up by Professor Rob Gross, of Imperial College, who said: “victory for leave creates uncertainty, risks instability, weakens the UK’s negotiating position and, at least in the short term, discourages investment.” The lack of stability and certainty will not only impact renewables but other low carbon energy projects; for example, the scraping of the controversial proposed nuclear power plant at Hinkley Point (which was to be built by the French company EDF) seems a likely outcome of the referendum.
It is clear that energy policy needs to be a priority for the new government, to give reassurance to the industry. However, even if it does become a priority it would seem optimistic not to view the vote to leave the EU as negative for the UK energy system and low carbon energy in particular.
