Domestic application of micro wind turbines in Ireland: Investigation of their economic viability

Abstract

a b s t r a c tElectricity generation from renewable sources of energy will be a key part in the development of future strategies for many countries globally. This renewable electricity generation will be hugely important for Ireland, due to its lack of fossil fuel resources. The extremely good wind resource available provides Ireland with the opportunity of generating vast amount of electricity from wind energy. Large-scale wind electricity generation reached 1264 MW installed capacity by January 2010 in Ireland. However, micro scale wind electricity generation has not been very popular in Ireland to-date. The unclear economics of micro wind turbines, under Irish conditions, is considered the biggest obstacle for expanding micro wind turbine installation in Ireland. This paper presents a methodology to accurately evaluate the economic viability of a micro wind turbine on a case-by-case basis. The methodology utilises the software programmes HOMER and Microsoft Excel 2007 for the energy and economic analyses. This paper also presents a realistic economic analysis of a number of micro wind turbines available in Ireland.

“…Additionally, another remarkable feature of wind energy is its wide accessibility in many areas of the world. Globally, renewable energy resources are abundantly available, and wind in particular is easy to harness in different regions (Li et al 2012;O'Rourke et al 2009). The statistics have shown that the wind power potential in the world is higher than our present demands of electricity consumption Abstract The knowledge of the probabilistic wind speed distribution is of particular significance in reliable evaluation of the wind energy potential and effective adoption of site specific wind turbines.…”

“…Consequently, the model used to describe their performance should also differ. A typical model for a wind turbine is described below [18][19][20]: (29) where Pe,ave is the average output power of the wind generator at wind speed V (m/s), Per is the nominal power (kW), uc is the startup rotating speed (m/s), ur is the nominal speed (m/s), uf is the final rotating speed (m/s), and c and k are the coefficients of correlation.…”

“…Thus, fossil fuels are still used even if not by electrical heaters. Renewable energy is encouraged by governments and societies, therefore the use of renewable sources such as solar, geothermal and wind energy [2], [3], [4] to produce electricity offers great opportunity for reducing the fossil fuels consumption level.…”
