Electricity Management Systems (EMS)

An Electricity Management System (EMS) ensures methodical management of energy with a view to continually improving energy performance.

Why promote energy management? Because it delivers results and benefits

Companies adopt energy management in order to reduce their costs and their impact on the environment, which helps them stay competitive without having to invest in new production equipment.

What’s more, energy consumption is a good indicator of the performance of the manufacturing process; by paying attention to it, companies can often optimize several aspects of their processes.

How to save energy through an EMS

Savings are achieved through daily actions within the organization (energy efficiency, energy recovery, waste reduction, and improvements in energy procurement).

The success of an EMS lies with the entire organization.

How to start

The first step in implementing an EMS is a diagnostic analysis, which provides an overview of a company’s energy consumption based on usage as well as its energy performance. The analysis proposes solutions for obtaining energy savings through operational improvements. It also defines the costs and benefits of features that can be implemented to continually improve energy performance.

Essential components

The EMS approach is made up of three components that are interrelated and that lead to the implementation of a system.

  1. Organizational change
  2. Company-wide behavioral changes
  3. Use of an energy management information system (EMIS)

Energy management systems involve human resources and work methods. These resources must be supported by an energy management information system (EMIS).

1. Organizational change

Here are some examples of organizational change:

  • Deployment of an energy policy setting out the major directions and objectives
  • Creation of an energy committee
  • Personnel training according to best practices in continuous energy management, based on ISO 50001
  • Modification of work habits according to continuous improvement practices (plan, do, check) at all levels of the organization
  • Clear definition of roles and responsibilities

2. Company-wide behavioral change

  • Controlling the main energy uses and needs
  • Determining and justifying the baseline consumption (with production levels considered)
  • Establishing relevant energy performance indicators, which are useful for:
    • understanding and planning for the company’s power consumption
    • determining whether energy performance is up to par or whether any abnormal situation is at play, and if so, the causes
    • quickly assessing the impact of corrective measures or procedural changes
  • Developing or adopting work procedures designed to control energy consumption

3. Use of an energy management information system (EMIS) for a thorough understanding of consumption

An EMIS is an essential part of energy management. Its design is based on existing systems and the needs of the various information users.

The EMIS establishes the way in which data, reports and indicators are integrated.

It continuously collects and analyzes energy consumption data from electromechanical systems, industrial processes and plant machinery.

The resulting data provide crucial support for employees’ efforts in energy performance improvement.
