An examination into the feasibility of powering small water services infrastructure using wind energy micro-generation auto-production

Abstract

This study examines the potential for the use renewable energy to meet some or all of the electricity requirements of small water services infrastructure. In particular the use of wind powered micro-generation auto-production is examined. While undertaking a literature review it became apparent that there is a lack of information relating to the use of micro/small wind turbines to power water services infrastructure. Furthermore, there is limited information relating to feasibility or site suitability guidelines for small scale wind. In Ireland, no such formal guidance exists. This study examines the theory and technology behind wind energy and the factors which influence the likely success or otherwise of a micro wind project. It includes the development of a feasibility template for a micro wind project comprising desk study and site survey elements. The template was used as a screening exercise to examine the feasibility of the use of wind micro-generation to power water services infrastructure in County Galway. Implementation of the feasibility template for a candidate site was undertaken with the aims of refining the methodology and proving the effectiveness of the template. The conclusions of this study include the following: • The feasibility template developed has the potential to be a useful tool for anyone considering installing a micro-wind turbine on their site. • There is potential for the use of wind micro-generation at water and wastewater infrastructure sites. • The economic payback period for micro-generation is much higher in Ireland than internationally and that in order to promote the development of the microgeneration industry in Ireland, appropriate feed in tariff rates are required.
