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 Programmes for Industry (IEA - IIP Joint Publication)

This study builds builds on lessons learned from country experiences with implementing Energy Management Programmes and provides actionable guidance on how to plan and design, implement, evaluate and monitor energy management programmes for industry.

Energy Management Systems Case Studies

Nyrstar Port Pirie Smelter

The Nyrstar Port Pirie smelter is more than 100 years old. Its smelting and ore refinery operations are energy intensive and complex. Due to the age of the site, there was very limited measurement and monitoring of energy use. Nyrstar recognized that real benefits would accrue from its Energy Efficiency Opportunities program assessment only if the company tackled inherent complexity and challenged old assumptions and practices. Nyrstar undertook a series of energy mass balances across the plant and used Sankey diagrams to illustrate energy inputs, outputs and potential savings.

OneSteel – Newcastle Rod Mill

This case study examines how OneSteel is embedding energy efficiency into its core business processes. It describes OneSteel's approach to energy efficiency through developing new systems and tools for the Sydney Steel Mills group, which are now being rolled out across OneSteel. As a result, OneSteel is expected to achieve annual energy savings of over 6% of total energy use through adopted savings opportunities identified by its assessments for the Energy Efficiency Opportunities program.

Alcoa Pinjarra

This case study showcases how Alcoa has set about managing and minimizing energy use and greenhouse gas emissions through:
- establishing public energy and greenhouse gas emissions targets;
- developing systems that regularly analyze, monitor and report energy performance;
- building information and communication networks to engage people, and;
- conducting rigorous and ongoing assessments to effectively identify continuous as well as `step-change’ improvements in the way energy is used.

 

Freescale Semiconductor – Successful EnMS Implementation

Five industrial facilities in Texas field tested the Superior Energy Performance program from 2008-2010 and became the first facilities certified through the program. These facilities achieved improvements in energy performance, ranging from 6.5% to 17% over a period of two to three years. This case study focuses on one of the first participants: the Freescale Semiconductor Oak Hill Fab plant in Austin, Texas.

Cook Composites and Polymers – Successful EnMS Implementation

Five industrial facilities in Texas field tested the Superior Energy Performance program from 2008-2010 and became the first facilities certified through the program. These facilities achieved improvements in energy performance, ranging from 6.5% to 17% over a period of two to three years. This case study focuses on one of the first participants: the Cook Composites and Polymers Co. (CCP) plant in Houston, Texas.
