INTRODUCTION MATERIALITY AND STAKEHOLDER ENGAGEMENT OUR CITY OUR OUR PEOPLE ENVIRONMENT GLOSSARY AT A GLANCE OUR ENVIRONMENT I TORONTO HYDRO 79 LIGHTNING MAPS Lightning strikes are a significant source of outages. To analyze the effect of lightning strikes on the system, Toronto Hydro mapped data relating to historical lightning strikes across the City of Toronto and correlated this data with system outage information. In the future, this information may be used for planning purposes to enhance resiliency in areas that are more prone to lightning activity. MAJOR EQUIPMENT TECHNICAL SPECIFICATIONS Toronto Hydro completed a review of Technical Specifications used for the purchase of major equipment in order to assess whether there are any opportunities to enhance the Technical Specification to provide additional resiliency. ASSET IMPACT STUDY Assets can be affected by climate change in different ways and at different magnitudes. To understand these differences, Toronto Hydro assessed how different asset types are affected by different aspects of climate change, and considered the measures that can be taken with respect to technical specifications and maintenance procedures to mitigate these climate-related risks. INDUSTRY REVIEW Toronto Hydro reviewed the climate adaptation plans of other utilities in Ontario, Canada and the United States to gain insight into best practices and policies. CLIMATE DATA Determining the future climate of Toronto will be as important as planning and investment decisions rely on this information. A review of various climate change information was completed to verify that projections used for planning purposes were valid and widely accepted. Ongoing monitoring of data will continue as government policy and economic factors may influence the direction of future climate. Additional initiatives in 2017 will include a review of Maintenance and Capital Programs, updating or creating new construction standards, revising standard design practices, and revising system planning guidelines to include climate change adaptation requirements. RESILIENT CITY WORKING GROUP - COLLABORATING WITH THE CITY ON CLIMATE CHANGE Throughout 2016, the Resilient City Working Group met on a regular basis to improve coordination with the City and other stakeholders to help mitigate the impacts of widespread outages. Toronto Hydro has been working with participants to identify areas of the grid that are vulnerable to extreme weather events and to improve information sharing processes to better prepare for major weather events and mitigate the impact on the City. PARTICIPATION IN INDUSTRY DISCUSSIONS Toronto Hydro continues to participate in the CEA-led industry discussions about the awareness of climate change impacts in the electricity generation, transmission and distribution sectors. Toronto Hydro presented its climate adaptation plans at the Electricity, Distribution, Information Systems and Technology conference in January 2016 to bring awareness about this important issue to the electric utility industry.
