Using Resources Wisely

Energy Efficiency at Hydro-Québec

 
Hydro-Québec implements energy efficiency measures when designing and operating its equipment and buildings. Various initiatives are also put forward to reduce energy consumption, improve the energy performance of our equipment and reduce system losses.
 
New facilities
follow the recommendations in the supplement to the provincial Regulation respecting energy conservation in new buildings. Recent examples include Montérégie, Boucherville and Langlois substations, and Toulnustouc and Mercier generating stations (thermal insulation, lighting systems, etc.).
 
The energy consumption of our equipment and buildings is monitored on a yearly basis to keep track of our progress in terms of energy performance.
 
Some Examples and Statistics
 
We installed automatic heating and air conditioning systems at Manic-5-PA generating station. We also made thermal improvements at Daniel-Johnson dam. These two measures should cut annual energy consumption by 33%.
We replaced the mercury vapor lamps at Daniel-Johnson dam with metal halide lamps, and reduced lighting hours. This measure yielded approximately 336,156 kWh in annual energy savings.
We also changed the lighting at Outardes-3 generating station, for annual energy savings totaling about 38.5%.
Various energy efficiency measures implemented throughout the company's administrative buildings in 2007 will generate estimated savings of 5,560 MWh per year.
