AVAILABILITY AND RELIABILITY Corresponds with Toronto Hydro’s Material Aspects: Grid Investment and Service Reliability Approximately 26% of Toronto Hydro’s infrastructure will be past its end of useful life by the end of 2015. As a result, we’ve been working hard to replace underground and overhead electrical equipment in order to continue to provide safe and reliable service to our customers. Management approach to availability and reliability Renewing the grid and replacing our distribution equipment is a costly endeavour. By 2020, another 7% of our equipment will be past its useful life, meaning over 30% will need to be upgraded or replaced. This represents billions of dollars of investment needs over the next decade and beyond. We’ve developed a five-year capital plan, which is subject to approval by the OEB. It establishes our proposed strategy for replacing aging assets and carrying out other important capital work in a manner that balances the need for proposed investments with consideration for customer impacts, the objectives of the Corporation, our work execution capabilities and other relevant factors.
