2 UTILITY LANDSCAPE IS CHANGING 2 Innovation

3 CUSTOMER NEEDS ARE CHANGING GREATER RELIABILITY STORM RESILIENCE HIGHER POWER QUALITY MODERATE ELECTRICITY COST INCREASES IF UTILITY SERVICES ARE INADEQUATE, THE CUSTOMER WILL FIND OTHER OPTIONS: DISTRIBUTED ENERGY RESOURCES NEW SERVICE PROVIDERS 3 Innovation

4 INNOVATION AT TORONTO HYDRO WE HAVE SEVERAL PROJECTS UNDERWAY: SUPPLY CAPACITY POWERLINE MONITORS & SMART METERS FEEDER AUTOMATION ENERGY STORAGE DEMAND RESPONSE ELECTRIC VEHICLES & TRANSIT ENERGY CENTRE 4 Innovation

5 SUPPLY CAPACITY Issue: Transmission into Toronto and downtown Station capacity are nearing limits. Near-term projects include: a) Copeland Transformer Station (TS) is a new underground station providing 288MVA capacity using gas-insulated transformers and gas-insulated switchgear for reliable operation in a very compact footprint which supports growth downtown. b) Manby x Wiltshire 115kV Line reinforcement on Manby East corridor uses high temperature, low sag conductor to increase capacity 120MVA to support corridor growth. 5 Innovation

6 POWERLINE MONITORS & SMART METERS Issue: Better visibility needed on distribution feeders: a) Upgrade of approx. 287 power line monitors supports reliability projects on worst performing feeders. Selfpowered, relocatable equipment provides voltage, current and power quality data. b) ION9000 power meters for all key account customers with power quality data capability c) Real-time data integration to our control room provides faster fault location, more efficient crew dispatch and ultimately helps improve restoration times. 6 Innovation

7 FEEDER AUTOMATION Issue: Distribution feeders need automation to improve reliability (SAIDI, SAIFI: a) Major automation program underway to implement feeder automation which will help limit outages to affected segments and preserve the balance of customers on the feeder, directly improving SAIDI and SAIFI. b) Joint study underway at Ryerson CUE to optimize the automation with re-closers, protection and communication for cost-effective solution. 7 Innovation

8 ENERGY STORAGE Manage Peak Demand Defer Conventional Infrastructure Support Power Quality & Resiliency Provide Operational Flexibility Integrate Renewables, EV & Public Transit Provide Ancillary Services These assets support bi-directional energy flows. We are involved in several pilot projects and are now implementing larger utility-scale projects. 8 Innovation

9 DEMAND MANAGE PEAK DEMAND Extends distribution system asset life through reduced loading at high temperatures Moderates on-peak pricing for customers by shifting to off-peak charging HYDROSTOR, 660kW/300kWh, UWCAES 24 HOURS 9 Innovation Source: Hydrostor 2015

10 SUPPORT POWER QUALITY & RESILIENCY Provide continuous power conditioning Reduce area voltage sags, spikes, harmonics Buffer supply during generator transfer HEALTHCARE, 12MW/3MWh, Li-Ion Batt. 10 Innovation Source: EPRI AEP Project

11 INTEGRATE RENEWABLES Integrates grid supply with 75kW solar system Buffers variable output of solar system Extends service life of 300kVA transformer RODING, 250kW/250kWh, Li-Ion Batteries 11 Innovation

14 SUPPORT ELECTRIC VEHICLES & TRANSIT Augment local supply with pole/pad storage Accommodate level 3 chargers where needed Provide supporting infrastructure & standards Augment Station supply where needed MODULES, 30kW/30kWh, Li-Ion Batt. 14 Innovation Source: ecamion

15 ENERGY CENTRE is developing an Energy Centre to provide visibility and enhanced control of resources operating in parallel with our system. The Energy Centre provides monitoring, forecast and control capabilities by extending SCADA points to these resources. This should allow greater penetration of distributed energy resources, manage peak demand and provide value to system operators. ENERGY CENTRE STORAGE STORAGE 15 Innovation
