A strategic review of energy management systems in significant industrial sites in Ireland

The purpose of this research was to carry out an analysis of a selection of large Irish industrial energy users, employing 6,800 persons, across a number of sectors, (Pharmaceuticals, Medical Devices and Semiconductor), to assess the role and development of effective energy management systems (EnMS¹) within their organisations. A comprehensive survey, completed by top management², was carried out with five large industry partners. It facilitated the assessment of the levels of maturity, perceived barriers to, and potential opportunities for the development of EnMS and sustainable manufacturing within their organisations. The final details relevant to each site have been validated by reviewing the results with each of the respondents. Those industries surveyed had an overall annual energy spend of €28 million, which resulted in 144,000 tonnes of carbon dioxide being emitted. The level of maturity of each EnMS was assessed, scored and compared. The lack of human and financial resources were identified as common barriers to the development of their EnMS. The most important energy performance indicators were identified and reported. All of the organisations have sustainability master plans and are interested in centralising the role of their EnMS. Each respondent reported that carbon will be a key production metric in the near future. There are certain key elements of the survey, such as the EnMS maturity matrix, which could be effectively applied across a larger number of industries. Such research would greatly enhance our knowledge of energy management systems.
