Toronto Hydro 2014 CR Report_FINAL

Facilities In 2014, our total electricity consumption at our facilities increased by 2.3% and natural gas consumption increased by 6% over 2013. This is partly attributable to: • Three new buildings added to our organizational boundaries23 • Colder winter conditions (more heating degree days24) • Employee relocation and major renovation projects, which required longer operating hours for affected facilities Despite increased electricity use, the GHG emissions from our facilities remained constant due to the lower provincial emission factor (the electricity mix in Ontario was less greenhouse gas intensive in 2014 relative to 2013, with less fossil fuel coal generated electricity). Line losses While our line losses remained consistent with 2013 values, the associated GHGs decreased by 2% due to the lower provincial emission factor. SF6 fugitive emissions Prior to 2014, our SF6 fugitive emissions were estimated (using a leak rate of 1.9%). In 2014, we used a new and more accurate process for tracking these emissions (for details see Data Sources). For this reason, our 2014 SF6 emissions increased by 29% relative to 2013. 56 TORONTO HYDRO 2014 CORPORATE RESPONSIBILITY REPORT Reducing our facilities footprint and boosting energy efficiency at 500 Commissioners St. Toronto Hydro’s Facilities department tracks energy consumption, square footage of buildings, and GHG emissions on a monthly basis through the use of a balanced scorecard. In 2014, we made some headway towards reducing our facilities environmental footprint and energy consumption. We improved the functionality of our buildings by closing our location at 5800 Yonge St. and making better use of existing spaces at 500 Commissioners St. Employees working in Information Technology (IT), Customer Care, and Grid Operations at our Yonge St. location were transferred to our building at Commissioners Street, reducing our total square footage by approximately 194,000 square feet. As part of the move, we renovated underused and redundant work spaces, converting locker rooms and labs to office facilities, downsizing and relocating our lab, building an updated data centre, and building a state of the art control centre. 23 New facilities were acquired and are under renovation so that employees from leased facilities can be relocated (and the leased agreements terminated). 24 Heating degree-days for a given day refer to the number of degrees Celsius that the mean temperature is below 10°C. If the temperature is equal to or greater than 10°C, then the number will be zero. For example, a day with a mean temperature of 7.5°C has 2.5 heating degree-days; a day with a mean temperature of 12.5°C has zero heating degree-days.
