TORONTO HYDRO 2014 CORPORATE RESPONSIBILITY REPORT 59 INTRODUCTION MATERIALITY AND STAKEHOLDER ENGAGEMENT OUR WORKFORCE SUSTAINABLE BUSINESS AND OPERATIONS OUR ENVIRONMENTAL FOOTPRINT SUPPORTING OUR COMMUNITY GOVERNANCE AND ETHICS Climate change adaptation We’re collaborating with a number of stakeholders and leading important initiatives to study the effects of climate change and help improve our system’s resiliency to severe weather. We’re also working to formalize our climate change adaptation action plan. Public Infrastructure Engineering Vulnerability Committee (PIEVC) Assessing our system for vulnerabilities to extreme weather In 2014, we conducted a vulnerability assessment study as part of the pilot phase of our PIEVC protocol project. The objective of the project was to evaluate the vulnerability of key components of our distribution infrastructure against current climate trends. We focused our attention on the most common infrastructure configurations in our grid, and analyzed equipment standards against current climate factors such as extreme temperatures and flooding. The study concluded that overhead infrastructure is more vulnerable to climate events than underground infrastructure, although underground equipment is not entirely sheltered from extreme weather. Following the case study, we launched phase two of the PIEVC protocol project with Engineers Canada, AECOM and Risk Sciences Canada to evaluate our distribution system against future climate trends. Through this project, we developed a risk assessment matrix for our infrastructure, and are in the process of mapping out areas of our distribution system that are expected to be impacted by future climate change. This information will be used to inform further research on climate adaptation and will help identify pilot projects. Resilient City Project Collaborating with the City of Toronto on climate change The Resilient City Project is aimed at improving coordination with the City of Toronto to mitigate the impacts of widespread outages. We’re working with the City to identify areas of our grid that are vulnerable to extreme weather events and improving our information-sharing processes to better prepare for events that could negatively impact the operation of the City. We have identified hospitals, public infrastructure providers and customers who depend on electrically powered life support equipment as key areas of planning. Knowledge gained from the PIEVC is being incorporated into this initiative to shape action plans. Participating in industry discussions In 2014, the CEA led industry discussions about the awareness of climate change impacts in the electricity generation and transmission sectors. Toronto Hydro participated in these roundtable discussions aimed to help educate members and gain consensus on common climate change issues and possible adaptation measures.
