Ontario's Electricity System

Understanding Ontario's Grid

Ontario's electricity system is managed by the IESO (Independent Electricity System Operator). It's one of the cleanest grids in North America — roughly 94% non-emitting. But demand is rising fast, and so are rates.

Ontario Energy Mix — Annual Average
⚛️Nuclear
48.5 – 51.0%
Constant baseload
💧Hydroelectricity
23.4 – 25.4%
Baseload and peak flexibility
🔥Natural Gas
12.5 – 16.6%
Fast-ramping peak power
💨Wind
7.9 – 9.0%
Variable intermittent resource
☀️Solar
1.0 – 2.3%
Intermittent summer-peak relief
🌿Bioenergy
0.4 – 0.8%
Supplemental generation
Pros & Cons of Each Source
⚛️
Nuclear — 48.5–51%
Darlington · Pickering · Bruce
Pros
✓ Zero carbon emissions during operation
✓ Extremely reliable 24/7 baseload
✓ Low cost per kWh once built
✓ Keeps Ontario grid 94% clean
Cons
✗ Massive refurbishment costs (Darlington: $12.8B)
✗ Long build timelines — decades
✗ Radioactive waste storage challenge
✗ Refurbishments drive rate increases
💧
Hydroelectricity — 23.4–25.4%
Niagara Falls · Ottawa River · run-of-river
Pros
✓ Zero emissions, renewable
✓ Can ramp up/down quickly for peak demand
✓ Very long asset life (50–100 years)
✓ Stores energy naturally (reservoirs)
Cons
✗ Limited by geography — Ontario is nearly maxed out
✗ Drought years reduce output
✗ Environmental impact on rivers
✗ High upfront construction cost
🔥
Natural Gas — 12.5–16.6%
Peaker plants · fast-ramping backup
Pros
✓ Fastest to ramp — minutes to full power
✓ Fills gaps when solar and wind drop
✓ Relatively lower cost to build
✓ Critical grid stability role
Cons
✗ Highest carbon emitter on the grid
✗ Ontario's only non-clean energy source
✗ Fuel price volatility
✗ Province committed to phase-out by 2030s
💨
Wind — 7.9–9.0%
Southern Ontario · Lake Erie · Lake Huron corridors
Pros
✓ Zero emissions, renewable
✓ Lowest cost per kWh of any new build
✓ Often peaks at night — complements solar
✓ No fuel cost, minimal ongoing expense
Cons
✗ Intermittent — can't be scheduled
✗ Geographic constraints
✗ Curtailment costs when grid is oversupplied
✗ Community opposition in some areas
☀️
Solar — 1.0–2.3%
Rooftop + utility-scale · fastest-growing source
Pros
✓ Peaks at midday — aligns with A/C demand
✓ Distributed rooftop reduces grid strain
✓ Rapidly falling costs — fastest growing globally
✓ Homeowners can participate directly
Cons
✗ No output at night or in heavy cloud
✗ Ontario winters limit seasonal output
✗ Requires storage (batteries) for evening use
✗ Grid integration needs planning
🌿
Bioenergy — 0.4–0.8%
Biomass · landfill gas · biogas
Pros
✓ Dispatchable — can be scheduled
✓ Uses waste materials (landfill gas, biomass)
✓ Carbon-neutral when sustainably sourced
✓ Supports rural communities
Cons
✗ Limited fuel supply — small scale
✗ Air quality concerns from combustion
✗ Land use competition
✗ Highest cost per kWh on the grid

Why are rates rising?

Ontario electricity rates have risen roughly 5% per year for over a decade. Key drivers include nuclear refurbishments at Darlington and Bruce ($12.8B and $13B+ respectively), the Global Adjustment charge that funds long-term contracts, growing delivery infrastructure costs, and new demand from EVs, heat pumps, AI data centres, and population growth.

Time-of-Use (TOU) and ULO rates

Ultra-Low Overnight (ULO) rates (3.9¢/kWh from 11PM–7AM) are ideal for EV charging and battery top-ups. On-peak rates (4–9PM weekdays) run 39.1¢/kWh — 10x the overnight rate. Shifting usage away from on-peak is the single easiest way to reduce your bill immediately.
