Energy Management Systems

Description: 

An energy management system (EnMS) is a collection of procedures and practices to ensure the systematic tracking, analysis and planning of energy use in industry. Systematic energy management is one of the most effective approaches to improve energy efficiency in industries, because it equips companies with practices and procedures to continuously make improvements and capture new opportunities.

Industrial energy efficiency can be greatly enhanced by effective management of the energy use of operations and processes. Experience shows that companies and sites with stronger energy management programs gain greater improvements in energy efficiency than those that lack procedures and management practices focused on continuous improvement of energy performance. Energy Management Systems provide such a framework to manage energy and promote continuous improvement. They establish assessment, planning, and evaluation procedures which are critical for actually realizing and sustaining the potential energy efficiency gains of new technologies or operational changes.

There are a number of guidelines aimed at helping companies to establish an effective EnMS - including those from the Australian Energy Efficiency Exchange, the Irish Sustainable Energy Authority, the United States Environmental Protection Agency, the United States Department of Energy and the recent ISO 50000 series of the International Standards Organization.

Energy Management Systems Case Studies

Darigold - Energy Management System Implementation

This case study focuses on Darigold, a dairy and food processing company based in the United States. By implementing an energy management system across their business, they have been able to make huge cost savings and reduce their greenhouse gas emissions. In 2011, Darigold made an executive-level commitment to formalize the company’s energy program - moving from incremental projects and energy data tracking to an energy management system modeled on the ISO 50001 Global Energy Management Standard.

3M – Energy Management System Implementation

This case study describes one of 3M's successful initiatives in the design and implementation of a successful energy management system at its Brockville production plant in Canada. In 2012, the Brockville plant obtained certification of the ISO 50001 global EnMS standard and is the first company in Canada to achieve Superior Energy Performance Partner Platinum level status.

Supply Chain Energy Efficiency Approaches at PepsiCo

This case study from Center for Climate and Energy Solutions provides details of PepsiCo's initiatives to reduce energy consumption in its supply chain. For PepsiCo, energy use in internal operations were not significant, but energy use was chiefly responsible for the carbon footprint of its product and majority of this footprint was outside its own operations.

Aughinish Alumina - The New Irish Energy Management Standard

Aughinish Alumina is the first Irish company to become certified to a formal energy management standard. The Standard ensures a fully strategic approach to energy management, which leads to a cost effective reduction in operating costs and an improvement in profitability. The company has already benefited from the Standard, identifying several major efficiency opportunities. It expects to continue to reap the rewards of meeting the Standard as energy management becomes a higher priority.

Midland Brick - Energy Efficiency Opportunities Assessment

For Midland Brick in Perth, energy represents some 40% of total production costs. The company has a clear incentive to reduce energy consumption wherever possible. Midland Brick participated in an Energy Efficiency Opportunities program trial assessment in 2006 and learned that a fresh approach using EEO guidelines could deliver further energy savings even in areas that had previously been identified and considered.

Energy Management Systems Presentations

Energy Management Systems in Iron and the Steel Industry

Ladislav Horvath of the World Steel Association presented on EnMS in the iron and steel industry at the China EnMS workshop organized by the Institute of Industrial Productivity. The presentation gives a thorough overview of main energy issues in iron and steel plants, and how these can be effectively addressed by energy management systems.
