Wildfires in Canada have increased significantly over the past three decades, with an unprecedented surge in the 2020s.
With Alberta's solar capacity factor at 20%, we would need to install about five times the solar capacity to generate and store enough energy for non-sunny periods.
Key Assumptions:To replace fossil fuels with solar and meet Alberta’s electricity needs, we’d need to dedicate a land area 27.5% larger than the entire city of Calgary—around 0.18% of Alberta's total land area—exclusively for solar power production. While Alberta’s vast land area makes this achievable, smaller countries with less space may struggle to meet their energy needs through solar alone, highlighting the importance of a diversified energy mix that includes nuclear and other low-carbon options.

This is a conservative, ballpark estimate of carbon pricing revenue across Canada. It does not include all provincial revenues and excludes Quebec’s cap-and-trade system due to structural differences in how revenue is generated and reported. The “federal” pool includes revenues collected in provinces and territories without their own carbon pricing systems (e.g. Alberta, Saskatchewan, Manitoba, Ontario, Yukon, Nunavut).

This table compares the 30-year lifetime cost of a 1 GW power plant across five technologies: natural gas combined cycle (multi-shaft), geothermal, small modular nuclear (SMR), solar PV (with sun tracking), and onshore wind. Cost inputs (capital costs, fixed and variable operations and maintenance costs, and gas plant heat rate) are taken from the U.S. Energy Information Administration (EIA), Annual Energy Outlook 2025 — Electricity Market Module assumptions (Table 3), based on 2024 USD. Source: EIA, AEO2025 Electricity Market Module Assumptions — Table 3.
To estimate total lifetime cost, the following components were calculated and summed for each technology:
Total lifetime generation is calculated as:
Finally:
To reflect typical utilization, the following average capacity factors were assumed:
Fuel cost assumptions:
Note: This is a simplified levelized-cost comparison. It does not include financing costs (discount rates, interest during construction), transmission buildout, curtailment, or the additional backup/storage required to make intermittent generation fully equivalent to firm generation.
In 2024, Canada generated 142.4 TWh of electricity from fossil fuels. To estimate how much firm clean energy would be required to replace this generation (e.g., geothermal or nuclear), we can convert annual electricity output (TWh) into an equivalent average power requirement (MW), then adjust for capacity factor.
Total electricity generated by fossil fuels (2024): 142.4 TWh/year (Natural gas — 110 TWh, Coal — 25.1 TWh, Other fossil — 7.3 TWh) Source: Ember Energy — Electricity Data Explorer (Canada, 2024) https://ember-energy.org/data/electricity-data-explorer/?entity=Canada&chart=single_year&tab=main
Equivalent average power requirement (100% capacity factor): 142.4 TWh = 142,400,000 MWh 142,400,000 MWh ÷ (24 × 365) = 16,255.71 MW
Installed capacity required at 92% capacity factor (geothermal / nuclear): 16,255.71 MW ÷ 0.92 = 17,669.25 MW
Planning allowance (future demand + reliability margin): Rounded estimate = 18,000 MW (18 GW)
This appendix documents how capital cost assumptions for geothermal power and Small Modular Reactors (SMRs) were derived for Chapter 10, including source data, scope, and currency conversion. All costs are expressed in Canadian dollars per gigawatt of nameplate capacity (after conversion from USD), consistent with the plan’s total build target of 18 GW nameplate.
Because nameplate capacity has already been sized to account for capacity factor, no additional capacity-factor adjustment is applied to capital costs.
The U.S. Energy Information Administration (EIA) reports overnight geothermal plant costs of approximately:
However, overnight costs exclude exploration, confirmation drilling, dry-hole risk, and system-level development. Studies that account for fully developed geothermal systems typically place costs in the range of US$5,000–6,500 per kW. To remain conservative and to reflect early-stage development and drilling risk, this analysis adopts the upper end of that range.
For planning purposes, this analysis adopts a conservative system-level cost of:
Converted at a representative exchange rate of 1 USD ≈ 1.36 CAD:
The U.S. Energy Information Administration (EIA) reports overnight capital costs for advanced nuclear reactors, including Small Modular Reactor designs, of approximately:
Published cost estimates for early-fleet SMRs generally fall in the range of $9,000–13,500 USD per kW, reflecting first-of-a-kind construction, regulatory risk, and limited standardization.
This analysis uses a conservative early-fleet average of: $10,500 USD per kW
Converted to Canadian dollars: ~$14.63 billion CAD per GW nameplate
The plan assumes a 50/50 split between geothermal and SMR capacity.
The average capital cost per gigawatt is calculated as the midpoint of these two technologies:
Applied to 18 gigawatts of total capacity:
These figures reflect system-level capital costs and do not assume cost reductions from learning curves, fleet deployment, or financing reforms discussed elsewhere in this chapter.
Operating and maintenance (O&M) costs are based on published fixed and variable O&M reference values for geothermal and nuclear facilities, drawn primarily from U.S. Energy Information Administration (EIA) and International Energy Agency (IEA) sources. A blended average is used, weighted evenly across geothermal and SMR capacity to reflect the plan’s 50/50 technology split.
For planning purposes, O&M costs are treated as Canadian-dollar costs and are not converted from USD, since the majority of operating expenses—labour, maintenance, services, and local operations—would be incurred domestically. Fuel cost estimates, where applicable, are converted from USD to CAD, reflecting exposure to international commodity pricing.

This section estimates annual net revenue from 18 GW of firm clean baseload capacity (50 percent geothermal / 50 percent SMR), using a single electricity price assumption grounded in provinces where fossil generation is more prevalent.
To avoid cherry-picking low-cost hydro provinces, we use a simple average of published/regulated energy rates (¢/kWh) from provinces that rely more heavily on fossil generation:
Assumed electricity price (simple average):
Note: these are customer-facing energy charges/rates (not wholesale). Using retail-ish prices is deliberate here because the plan’s “return” is ultimately captured through what the electricity system can charge and recover over time.
Step 1 — Annual gross revenue:
Step 2 — Operating margin (after O&M):
Step 3 — Annual financing cost (effective interest):
Step 4 — Pre-tax profit:
Step 5 — Taxes (25 percent):
Step 6 — Annual net revenue (after O&M, interest, and tax):
NOTE: This analysis applies a conservative flat tax rate for simplicity. In practice, large clean energy projects in Canada qualify for accelerated capital cost allowance, substantially reducing taxable income in early years. As a result, actual taxes paid would be materially lower than modeled here, particularly during the amortization period. Net revenues presented in this appendix should therefore be understood as conservative estimates.
This section estimates how long it takes for the project to recover its initial capital investment using the annual net revenue calculated above.
At the assumed electricity price and financing/tax assumptions used in this appendix, the clean baseload build reaches capital payback in roughly 20–21 years.
Note: This is a simplified payback estimate using a steady annual net-revenue figure. It does not model ramp-up timing, principal repayment schedules, depreciation/tax shielding, or changes in electricity prices over time.
This section estimates cumulative net profit over a 30-year horizon using a mortgage-style financing model, and then accounts for the post-amortization surplus once the capital investment has been fully repaid.
For the first 30 years, annual net operating revenue is primarily used to service capital.
Annual retained surplus during amortization:
Cumulative retained surplus (Years 1–30):
By the end of year 30:
Once the capital is fully repaid, annual revenues are no longer consumed by debt service.
At current prices and assumptions:
This represents true surplus—available for rate reductions, reinvestment, public revenue, or accelerated decarbonization elsewhere in the economy.
Even without assuming price growth or efficiency gains:
Over the first 30 years alone, the system:
From year 31 onward, the system transitions from a debt-servicing asset to a high-margin public energy asset, generating on the order of $10B per year in net surplus at 2025 electricity prices.
The net revenue figures above are deliberately conservative. They assume a steady effective tax rate throughout the amortization period and therefore understate retained value in the early and middle years of operation. In reality, capital-intensive infrastructure such as geothermal and nuclear power benefits from accelerated capital cost allowance (CCA) and interest deductibility, which significantly reduce taxable income while capital is being repaid. Rather than modeling a detailed year-by-year depreciation schedule, this adjustment treats taxes avoided through CCA as retained value over the 30-year financing horizon.
Planning-level impact:
This does not change the underlying economics of the system. The conservative case demonstrates viability even under simplified assumptions. The CCA-adjusted case reflects how large-scale energy infrastructure is actually financed and taxed in practice, and why public ownership or public-backed financing materially improves long-term outcomes.
This estimate calculates direct (stack) CO₂ emissions avoided by replacing fossil baseload generation with 18 GW of firm clean power (50 percent geothermal / 50 percent SMR).

Total annual emissions avoided:
Planning note:
According to Canada’s National Inventory Report, natural gas–fired electricity generation emitted approximately:
This figure is used as the baseline for modeling carbon capture retrofits.
Not all natural gas facilities are suitable candidates for retrofit. Low-utilization peaker plants operate only during short periods of peak demand and are unlikely to justify capital-intensive upgrades. This model assumes retrofits target high- and mid-merit facilities responsible for the majority of emissions.
For modeling purposes, we assume:
Estimated annual emissions avoided:
This is the maximum technical capture potential if the majority of baseload and mid-merit gas units are retrofitted.
Installed natural gas generation capacity in Canada (2023): 23.66 GW
Not all of this capacity operates at high utilization. For modeling purposes, we assume:
For calculation simplicity, this appendix uses: 17 GW retrofit target
Estimated retrofit cost for NGCC plants with carbon capture: ~$1,700 CAD per kW
This estimate reflects inflation-adjusted values from historical CCS retrofit studies and current industry cost ranges.
Total retrofit capacity: 17 GW = 17,000,000 kW
Capital cost calculation:
Estimated cost to capture and manage CO₂: ~$70 per tonne CO₂
Annual captured emissions: 21.7 Mt × $70 = $1.52 billion per year operating cost
(If capture rates or cost per tonne vary, this number scales proportionally.)
Assuming 25-year amortization: $29 billion ÷ 25 years = $1.16 billion per year
Total annual cost (capital + operating): $1.16B + $1.52B = $2.68 billion per year
To convert costs into per-kWh impact, we estimate total annual gas generation.
Using installed capacity:
81.9 TWh = 81.9 billion kWh
Total annual cost ÷ annual generation: $2.68B ÷ 81.9B kWh = $0.0327 per kWh (~3.3 cents per kWh)
Assumptions:
Total cost:
Assumptions:
Total cost:
Lower interest + longer amortization materially reduces annual capital burden.
Assumptions:
Total cost:
| Financing Model | Estimated Cost per kWh | Household Impact (7,200 kWh) |
|---|---|---|
| Full Pass-Through | ~3.25¢ | ~$234/year |
| Federal Low-Interest Financing | ~2.30¢ | ~$166/year |
| Blended Federal Support (30% capital offset) | ~1.96¢ | ~$141/year |
At a federal carbon price of $170 per tonne: 21.7 Mt × $170 = $3.69 billion per year avoided carbon exposure
This avoided liability exceeds estimated operating costs and partially offsets capital investment when carbon pricing remains in place.
Installed natural gas capacity (2023): 23.66 GW
Assumed capture rate: 90% → 24.1 Mt × 0.90 = 21.7 Mt captured per year
30-year cumulative emissions avoided: → 21.7 Mt × 30 = 651 Mt CO₂e
Capital cost: ~$29B → $29B ÷ 651 Mt = ~$45 per tonne (capital only)
Operating cost: ~$1.52B per year → $1.52B × 30 = $45.6B over 30 years
Total 30-year cost: → $29B + $45.6B = $74.6B total
All-in cost per tonne (30-year horizon): → $74.6B ÷ 651 Mt = ~$115 per tonne
The following estimate focuses primarily on industrial warehouses, distribution centres, and large-format commercial buildings, which are typically single-storey structures. For these building types, reported industrial inventory closely approximates roof area.
According to Cushman & Wakefield’s Canada Industrial MarketBeat (Q4 2025), total national industrial inventory is:
Industrial inventory consists predominantly of warehouse, logistics, and distribution facilities, which are overwhelmingly single-storey buildings with large flat roofs. As such, total inventory square footage serves as a reasonable proxy for available rooftop area.
Source: Cushman & Wakefield - Q4 2025 Canada Industrial Marketbeat Report https://www.cushmanwakefield.com/en/canada/insights/canada-marketbeats/industrial-marketbeats
Utility-scale and commercial rooftop systems typically install:
2.07 billion sq ft × 0.02 kW per sq ft = 41,400,000 kW = 41.4 gigawatts (GW) of theoretical installed capacity
Not all rooftops are usable due to:
To remain conservative:
41.4 GW × 0.6 × 0.7 = 17.4 GW realistically installable capacity
Average Canadian commercial solar capacity factor: ~18 percent
17.4 GW × 8,760 hours/year × 0.18 = 27,417 GWh per year
Canada’s annual electricity consumption: ~625,700+ GWh (2021)
27,417 GWh ÷ 625,700 GWh = ~4.4 percent of national electricity demand
Even under conservative assumptions, commercial rooftop solar in major cities alone could supply roughly five to six percent of Canada’s total electricity demand.
This would:
Tier 2 – Expanded Commercial & Institutional Potential
The above estimate includes only national industrial inventory. It excludes:
Including these additional categories would materially increase national rooftop solar potential. A conservative expansion suggests total rooftop capacity could reasonably approach five to six percent of national electricity demand when broader commercial and institutional structures are included.
Solar energy potential is often underestimated in northern climates. In reality, several Canadian cities receive as much—or more—annual sunshine as locations much farther south.
Photovoltaic panels also operate more efficiently in cooler temperatures, meaning cold climates can partially offset shorter winter days through improved panel efficiency.
This appendix outlines the assumptions used to estimate electricity generation, economic value, and emissions reductions associated with installing approximately 17 gigawatts of commercial rooftop solar capacity across Canada.
This capacity factor reflects typical solar performance across Canadian provinces when seasonal variation in sunlight is considered.
Annual electricity generation is calculated using the standard production formula:
Rounded value used in the chapter: ~27 TWh per year
Average Canadian household electricity consumption is roughly 10,500–11,000 kWh per year.
Result used in the chapter: Equivalent to powering approximately 2.5 million Canadian households.
Commercial electricity prices in Canada vary widely by province. Typical blended commercial rates fall between $0.10 and $0.12 per kWh.
Estimated annual electricity value: ~$2.7–3.2 billion per year
This represents avoided electricity purchases by building owners rather than wholesale electricity sales.
Canada’s electricity system is already dominated by low-carbon sources such as hydropower, nuclear, and wind. Fossil fuels supply roughly 21 percent of total generation.
Average emissions intensity of fossil generation in North America is approximately 430–450 kg CO₂ per MWh, largely reflecting natural gas generation.
For comparison, U.S. natural gas power plants averaged 437 kg CO₂ per MWh in 2024.
To estimate the portion of rooftop solar generation likely to displace fossil generation, the fossil share of the grid is applied.
Emissions avoided:
Estimated annual emissions avoided: ~2.5–3 Mt CO₂e per year
Installing 17 GW of commercial rooftop solar across Canada would generate roughly 27 TWh of electricity annually, equivalent to the power consumption of about 2.5 million homes.
This appendix outlines the assumptions and calculations used to estimate the electricity generation and emissions reductions associated with Pillar I.
Recent Canadian electricity generation is approximately 630–650 terawatt-hours (TWh) per year.
Pillar I adds two major sources of new generation:
Firm clean baseload generation
This estimate is derived by multiplying installed capacity by annual operating hours:
18 GW × 8,760 hours per year × 90 percent capacity factor ≈ 142 TWh per year
Commercial rooftop solar
Total new clean generation
Combining these sources produces approximately:
Relative to Canada’s current electricity generation of roughly 640 TWh annually, this represents an increase of approximately:
In other words, Pillar I increases Canada’s clean electricity supply by roughly 25–27 percent.
Only the portion of electricity that displaces fossil generation reduces emissions.
Approximately 21 percent of Canada’s electricity currently comes from fossil fuels, primarily natural gas.
Assuming that the new clean generation displaces fossil generation in proportion to its share of the grid:
Natural gas power plants emit roughly 437 kilograms of CO₂ per megawatt-hour (MWh) on average.
Source:
Converting displaced generation to emissions reductions:
This means the clean generation portion of Pillar I reduces emissions by approximately:
Carbon capture systems installed on natural gas plants are assumed to capture approximately 90 percent of plant emissions.
Natural gas plants typically emit 0.4–0.45 tonnes of CO₂ per MWh of electricity produced.
If the retrofitted plants collectively generate approximately 75 TWh of electricity per year, total emissions without capture would be:
Capturing 90 percent of those emissions results in avoided emissions of approximately:
Combining both sources of reductions produces the following estimate:
| Source | Annual reduction |
|---|---|
| Clean generation displacing fossil electricity | ~15–16 Mt CO₂ |
| Carbon capture retrofits | ~29–30 Mt CO₂ |
Total estimated emissions reduction: ~44–46 million tonnes of CO₂ per year
For context, Canada’s total annual greenhouse gas emissions are roughly 670 million tonnes. Pillar I therefore reduces national emissions by approximately 6–7 percent.
Canada currently generates a little over 600 TWh of electricity per year.
Federal projections indicate electricity demand could rise to roughly 750 TWh by 2035, while long-term net-zero scenarios suggest demand may exceed 1,200 TWh by 2050 in a high-electrification future.
Sources:
With ~169 TWh of new clean generation, Pillar I would provide:
In practical terms, this means Pillar I alone could meet roughly one-quarter to one-third of Canada’s projected electricity demand growth over the coming decades.
To replace Canada’s current natural gas consumption with hydrogen on an energy-equivalent basis would require approximately: ~37 billion kilograms of hydrogen annually.
Producing hydrogen via electrolysis at the scale required to replace Canada’s natural gas consumption would require:
~220 GW of continuous electricity demand
This exceeds Canada’s current total installed electricity generation capacity.
This table compares the operating and maintenance (O&M) costs for a 1,000 MW geothermal plant and a 1,000 MW small modular reactor (SMR) nuclear plant. The calculations include variable and fixed costs and highlight the impact of operating at 90% capacity, which is typical for both plant types.
