Regionalization of Central Operations

In the Spring of 2017, the decision was made to regionalize OPG’s Central

• perations, based in North

Bay.

Regionalization saw the Northeast Plant Group inherit:

• 3 additional river systems

 7 additional generating stations  8 additional control dams

Priorities for managing water flows are generally:

Implementation

• 1. Safety
• 2. Environment
• 3. Compliance with

Applicable law

• 4. Revenue Generation

WMP Priorities

• 1. Flooding
• 2. Erosion
• 3. Power Generation
• 4. Fisheries
• 5. Aquatic Ecosystem
• 6. Water Supply
• 7. Social/Recreational

Activities

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
• n the rivers and lakes when making decisions to release water in order to

balance the interests

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

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.
