Testimonials on Electricity Management Systems — Industrial Systems program


Obtain financial assistance for implementing an electricity management system (EMS) at your plant. Install equipment that measures the real-time consumption of the main processes, systems and equipment.

By adopting sound management practices, you can continuously improve your efficiency and save energy and money.

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

EMS explained by two experts (in French only).

Domtar-Windsor: great strides towards the implementation of electricity management systems (EMSs)

Michel Lemieux, Eng., Technical Services Manager and Alain Ouellet, Eng., Energy Projects Engineer
“The implementation of electricity management systems at Domtar-Windsor led us to focus on energy, which is now an integral part of our priorities and practices.”
(Michel Lemieux, Technical Services Manager)

The Domtar plant in Windsor, which employs 820 people, has processed logs into finished products for over 150 years. Following the first phase of the implementation of the electricity management systems (EMSs), Domtar-Windsor was able to apply new procedures. Simply by modifying its production processes and without requiring the purchase of new production equipment, the company managed to reduce its electricity consumption by 2% per unit produced on machine no. 8.

Great strides towards the implementation of electricity management systems (EMS) (in French only)

What strengths was Domtar-Windsor able to leverage in rolling out its EMSs?

  • Integrated environmental and continuous improvement practices: most notably, the mill has obtained ISO 14001 and FSC Chain of Custody certifications
  • Energy performance assessment at the mill
“Management’s commitment along with a systematic process are the keys to the success of electricity management systems.”
(Alain Ouellet, Energy Projects Engineer)

What were the results in the initial months after implementing the EMSs?

  • The identification and implementation of three operational measures generating annual recurrent energy savings—a 2% decrease in energy consumption per unit produced by machine no. 8.

What were the main steps in implementing emss at Domtar-Windsor?

Initially, what were the main challenges?

  • Adopting and communicating a corporate vision for energy performance (energy policy)
  • Assembling an energy committee to oversee energy performance (including someone from the production sector)
  • Raising awareness of energy consumption among employees by:
    • creating energy account centres within the mill
    • defining roles and responsibilities

What commitments has upper management made?

  • To take energy consumption into account when making investment decisions
  • To maintain and service equipment to ensure energy efficiency
  • To raise awareness of energy consumption among employees

What was the key finding of Domtar-Windsor’s energy report?

A significant share of the mill’s total energy consumption is attributable to paper machine no. 8.

How was the improvement potential of machine no. 8 determined?

Software was used to analyze consumption and its variations, and the results were as follows:

  • Almost 20% of consumption is not directly linked to production
  • Machine no. 8 consumes an excessive amount of energy for unknown reasons

A more detailed level of measurement was integrated in order to define and monitor energy performance indicators and ongoing consumption management measures.

Measures that do not require investments:

  • Optimization of the use of the paper machines’ vacuum pumps
  • Reduced consumption for heating through a glycol energy recovery loop
  • Optimization of the cooling system used at the product conversion stage

What are the prospects for the future?

  • Mill-wide implementation of EMSs
  • Identification of new ongoing consumption management measures to reduce the plant’s total energy consumption by at least 3%

Waterville TG: a new way of fostering energy efficiency

Serge Lamontagne, Eng., Assistant General Manager – Manufacturing Engineering and Services and Audrey Garcin, M. Sc. Environment Specialist
“For the project to be successful, technologies aren’t enough. You have to make sure users are on board and foster a power-saving culture.”
(Serge Lamontagne, Assistant General Manager – Manufacturing Engineering and Services)

Waterville TG is a world leader in automotive sealing systems. Its parent company, Toyoda Gosei, is based in Japan and has some 1,900 employees in Canada, over half of whom work in Waterville.

Thanks to the implementation of electricity management systems, Waterville TG identified an initial target of close to $150,000 in potential recurring annual electricity savings. The company set out to achieve its target by having its operators manage its extrusion line shutdown time more effectively.

A new way of fostering energy efficiency (in French only)

What strengths was Waterville TG able to leverage in rolling out its EMSs?

  • Energy efficiency culture
  • Proficiency in continuous improvement practices (Toyota Production System)
  • Structured environmental measures: ISO 14001:2004 certification
  • Motivated employees
“Above all, an EMS is a cultural change for this generation and the next!”
(Audrey Garcin, Environment Specialist)

What were the main steps in implementing EMSs at Waterville TG?

What were the main challenges at the outset?

  • Demonstrating the potential for electricity savings to senior management
  • Lack of energy efficiency measurements and performance indicators
  • Achieving a common vision (energy policy)
  • Forming an energy committee and designating a production manager

What was the audit used for?

It helped identify a significant use in order to better target EMS implementation.

Extrusion activities were the most energy-intensive, accounting for over 60% of the electricity used by the entire plant.

How was that potential determined?

By using temporary metering on two extrusion lines for 14 days.

What was the goal?

To determine the impact on energy consumption and optimal shutdown times during non-production periods.

What were senior management’s main commitments?

  • Continuous power use reduction targets
  • Making required information and resources available in support of the company’s objectives
  • Communicating results and doing the required follow-up
“The electricity management systems were implemented successfully thanks to cooperation among various departments. Their combined efforts really illustrate the idea of ‘One Team, One TG.’”
(Audrey Garcin, Environment Specialist)

What were the initial results of implementing the EMSs?

  • A decrease in electricity consumption
  • Fast return on investment
  • EMSs were incorporated into existing systems
  • Motivated employees driven by energy efficiency culture
  • Environmental goals were achieved more easily

What are the prospects for the future?

  • Implementation of an energy management information system (EMIS) for all significant energy uses
