Gaz Métro


Launched in 2002, Gaz Métro’s program to encourage companies to implement energy efficiency measures (Encouragement à l’implantation de mesures d’efficacité énergétique) was meant to help commercial, institutional and industrial (CII) clients by offering them a grant to cover a portion of the implementation costs.

The program has been evaluated twice since inception. The most recent evaluation was completed in 2009.

In June 2010, members of the Régie de l’énergie [Quebec Energy Board] stated they were dissatisfied with the evaluation exercise for the program. In their decision, they insisted on the weight of the program within Gaz Métro’s portfolio and asked a precise quantitative measurement method be proposed to assess the energy impact of the program.

In the fall of 2011, in response to the Régie’s request, Gaz Métro submitted a precise quantitative measurement method to assess the energy impact of the program: a pre- and post-implementation measuring exercise for certain measures, targeted within a sample of the most frequently implemented measures for each of the three largest customers of the CII and Major Industries Sales (MIS) sectors.

Gaz Métro launched a call for tenders to proceed with the evaluation of its program to encourage companies to implement energy efficiency measures for all three components aimed at the large customers of the CII and MIS sectors.

In this context, Econoler was chosen to complete the assignment.


Econoler was asked by Gaz Métro to evaluate the program for the years 2011-2012, 2012-2013 and 2013-2014. This assignment required a process, market and energy impact assessment.
To complete this assignment, Econoler undertook the following tasks:
  • meetings with managers and designers of Gaz Métro’s program, along with the engineers of the DATECH Group;
  • analysis and processing of the program’s databases;
  • design of collection tools, such as sampling plans and questionnaires for telephone surveys, and interview guides for engineers;
  • review of files to confirm whether measurements made were consistent with best practices;
  • design of an engineering algorithm for the energy to assess the program’s energy impact and distortion effects;
  • data collection from surveys of participating and nonparticipating companies;
  • review of unit gains and extrapolation of the sample results to the rest of the participants;
  • calculation of gross and net energy impact of the program.
Econoler’s evaluation of the program revealed the effects of the program on the market. It also allocated Gaz Métro its fair share of the energy savings generated by the program.
