4 Northeast Operations  21 Hydroelectric Generating Stations  22 control dams  7 river systems (Mattagami, Abitibi, Matabitchuan, Montreal, South, Sturgeon, Wanapitei)  6 service centres (Abitibi Canyon, Dymond, Kapuskasing, Timmins, North Bay, Coniston)  More than 250 employees throughout the Northeast  Generating capacity of more than 1600 megawatts .  S A Y I T D O I T  SIM PLIFY I T  T H I N K T O P A N D B O T T O M L I N E  I N T E G R A T E A N D C O L L A B O R A T E  T E L L I T A S I T I S

Regionalization of Central Operations In the Spring of 2017, the decision was made to regionalize OPG’s Central operations, based in North Bay. Regionalization saw the Northeast Plant Group inherit: • 3 additional river systems  7 additional generating stations  8 additional control dams  S A Y I T D O I T  SIM PLIFY I T  T H I N K T O P A N D B O T T O M L I N E  I N T E G R A T E A N D C O L L A B O R A T E  T E L L I T A S I T I S

9 P r e s e n t a t i o n T i t l e Priorities for managing water flows are generally: WMP Priorities Implementation 1. Flooding 1. Safety 2. Erosion 2. Environment 3. Power Generation 3. Compliance with Applicable law 4. Fisheries 4. Revenue Generation 5. Aquatic Ecosystem 6. Water Supply 7. Social/Recreational Activities  S A Y I T D O I T  SIM PLIFY I T  T H I N K T O P A N D B O T T O M L I N E  I N T E G R A T E A N D C O L L A B O R A T E  T E L L I T A S I T I S

10 Reservoir Drawdown • Where applicable, reservoirs are drawn down over the winter according provincially mandated Water Management Plans • Goal: reservoirs at lowest level by the time inflow increases during freshet (i.e. OPG will have maximized the revenue and put the facility in a safe position) • Water that can be stored in the reservoirs helps mitigate flooding risks • OPG works with MNRF, local Conservation Authorities, and other stakeholders on the rivers and lakes when making decisions to release water in order to balance the interests  S A Y I T D O I T  SIM PLIFY I T  T H I N K T O P A N D B O T T O M L I N E  I N T E G R A T E A N D C O L L A B O R A T E  T E L L I T A S I T I S

11 Snow surveys and weather forecasts  Snow surveys are conducted to measure snow depth and water content in order to provide an indication as to how much moisture could drain into a catchment area.  Knowing how much water could enter the river system does not indicate how much water will enter river systems.  Other factors influence water levels Weighing a core sample of snow including temperature (daily highs and nightly lows), sublimation, vegetation and precipitation. ≠  Decisions have to be made weeks and even months in advance using the best available data.  S A Y I T D O I T  SIM PLIFY I T  T H I N K T O P A N D B O T T O M L I N E  I N T E G R A T E A N D C O L L A B O R A T E  T E L L I T A S I T I S
