Executive Summary
The Pricing Power Thesis: Constellation Energy (CEG) has achieved something unprecedented in commodity electricity markets—83-92% premiums over renewable energy through 20-year fixed-price PPAs with Microsoft and Meta. This isn’t irrational exuberance. It’s the logical outcome when:
- AI training cannot tolerate interruption ($14,125/hour loss)
- Nuclear provides 99.5% uptime vs. wind/solar 25-35%
- Hyperscalers need 24/7 zero-carbon power for ESG commitments
- Grid interconnection queues stretch 5-9 years
- SMR alternatives won’t scale until 2029-2032
The Numbers:
- CEG nuclear capacity: 22.1 GW (3.5x larger than #2 competitor)
- Microsoft TMI deal: 835 MW, $110-115/MWh, 20 years = $86.7B cumulative
- Meta Clinton deal: 1,121 MW, ~$70/MWh, 20 years = $70.4B cumulative
- Combined annual cash flow: $7.86-9.62B from just 2 contracts
- Replication potential: 19 more reactors available for similar deals
Investment Verdict: CEG is the purest play on AI’s structural power demand. While PE 35-39x seems expensive, the Microsoft/Meta contracts fundamentally re-rate the business from commodity generator to premium infrastructure provider.
Part 1: Why Nuclear Wins for AI
1.1 The Reliability Imperative
AI Training Interruption Economics:
100,000 GPU Cluster Operating Cost:
100K GPUs × $2/GPU-hour = $200K/hour
Single hour interruption:
- Direct loss: $200K operations
- Checkpoint reset: 99 iterations wasted = $110K
- Total: $310K
Annual cost comparison (Tier II vs. Nuclear):
Tier II datacenter: 22 hours downtime × $310K = $6.8M
Nuclear-powered: 1.6 hours downtime × $310K = $496K
Savings: $6.3M annually per 100K GPU cluster

Why Nuclear Beats Renewables:
| Metric | Nuclear | Wind | Solar | Natural Gas |
|---|---|---|---|---|
| Capacity Factor | 92-95% | 25-35% | 20-25% | 50-60% |
| Uptime (Annual) | 99.5% | Intermittent | Intermittent | 95-97% |
| Carbon Emissions | 0 g CO2/kWh | 0 | 0 | 400-500 g |
| Fuel Cost Volatility | Low | Zero | Zero | High |
| Grid Independence | ✅ Yes | ❌ No | ❌ No | ✅ Yes |
Key Insight: For AI training, reliability > cost. Nuclear is the only technology delivering 24/7 zero-carbon baseload power with 99.5%+ uptime.
1.2 The Microsoft Economics
Why Pay $110-115/MWh vs. $60/MWh for Renewables?
Scenario Analysis:
Option A: Renewable Energy (Wind/Solar + Battery)
- PPA price: $60/MWh
- Capacity factor: 30%
- Intermittency: Forces backup power or training delays
- Battery storage: Adds $40/MWh (4-hour duration)
- Effective cost: $100/MWh + reliability risk
Option B: Nuclear (Three Mile Island)
- PPA price: $110/MWh
- Capacity factor: 93%
- Uptime: 99.5% (24/7/365)
- No backup needed
- Total cost: $110/MWh, zero risk
Premium: $10-15/MWh
Interruption insurance value: $14,125/hour ÷ 835 MW = $16.9/MWh
ROI on premium:
$16.9/MWh insurance > $10-15/MWh cost
Positive arbitrage = Rational decision
ESG Multiplier:
- Microsoft’s 2030 commitment: Carbon negative
- Nuclear: Only 24/7 zero-carbon technology at scale
- Wind/solar + batteries: Still has embodied carbon, intermittency issues
- Reputational value: Priceless for $3T market cap company

Financial Model:
| Scenario | PPA Price | Annual Revenue | Annual O&M | Net Cash Flow | 20-Year NPV |
|---|---|---|---|---|---|
| Conservative | $100/MWh | $655M | $262M | $393M | $7.86B |
| Base Case | $110/MWh | $721M | $287M | $434M | $8.67B |
| Optimistic | $115/MWh | $753M | $295M | $458M | $9.16B |
Assumptions:
- Capacity factor: 90% (conservative vs. 94.8% fleet average)
- Annual generation: 835 MW × 8,760 hours × 90% = 6.55 TWh
- O&M cost: $30-40/MWh (industry standard)
- Discount rate: 6% (investment-grade utility WACC)
- Not including: Federal 45Y PTC (production tax credit) = additional $5-10/MWh benefit
Payback Analysis:
Investment: $1.6B
Annual net cash flow: $434M (base case)
Simple payback: 3.7 years
IRR: ~25% (exceptional for infrastructure)
Why This Matters: The Microsoft deal alone adds $8.67B NPV to CEG’s valuation—roughly 10% of current market cap from a single asset restart.
2.3 Meta Clinton Nuclear Station Deal
Project Overview:
- Facility: Clinton Nuclear Station (Illinois)
- Capacity: 1,121 MW (entire plant output)
- Status: Operating asset (no restart required)
- Contract: 20-year PPA with Meta, starting June 2027
- Upgrade: +30 MW power uprate included
Financial Model:
| Scenario | PPA Price | Annual Revenue | Annual O&M | Net Cash Flow | 20-Year NPV |
|---|---|---|---|---|---|
| Jefferies Est. | $70/MWh | $616M | $264M | $352M | $7.04B |
| Market Est. | $85/MWh | $748M | $308M | $440M | $8.80B |
| Bull Case | $100/MWh | $880M | $352M | $528M | $10.56B |
Assumptions:
- Capacity factor: 90%
- Annual generation: 1,121 MW × 8,760 × 90% = 8.8 TWh
- O&M: $30-40/MWh
Key Observations:
- Lower pricing than Microsoft ($70 vs. $110/MWh):
- Clinton is existing asset (no restart capital risk)
- Meta signed earlier (less competitive bidding)
- Still 17-42% premium over renewable PPAs ($50-60/MWh)
- Larger capacity (1,121 MW vs. 835 MW):
- Compensates for lower price
- Similar total value contribution
- Earlier delivery (June 2027):
- Provides cash flow before TMI-1
- De-risks restart execution
Combined Microsoft + Meta Value:
Conservative (TMI $110/MWh + Clinton $70/MWh):
Annual: $434M + $352M = $786M
20-year: $8.67B + $7.04B = $15.71B
Optimistic (Both $110/MWh):
Annual: $434M + $528M = $962M
20-year: $8.67B + $10.56B = $19.23B
Strategic Significance: Two contracts alone could add $15-19B NPV, roughly 15-20% of CEG’s current enterprise value.
Part 3: Replication Potential
3.1 CEG’s Remaining Assets
Available for Additional PPAs:
Total CEG nuclear: 22.1 GW
Already contracted:

3.2 Replication Scenarios
Conservative Case (5 GW by 2028):
5 GW × 8,760 hours × 90% CF = 39.4 TWh/year
At $100/MWh average: $3.94B annual revenue
Less O&M (35%): $2.56B annual net cash flow
20-year NPV (6% discount): $51.2B
Base Case (10 GW by 2030):
10 GW × 8,760 × 90% = 78.8 TWh/year
At $100/MWh: $7.88B revenue
Net cash flow: $5.12B annually
20-year NPV: $102.4B
Bull Case (15 GW by 2032):
15 GW × 8,760 × 90% = 118.2 TWh/year
At $100/MWh: $11.82B revenue
Net cash flow: $7.68B annually
20-year NPV: $153.6B
Reality Check:
- Hyperscaler AI capex: $200-300B annually (AWS, Azure, GCP, Meta combined)
- Power as % of capex: ~15-20%
- Available for nuclear PPAs: $30-60B annually
- CEG’s addressable: 10-15 GW over 5-10 years = plausible

- Delivery: 2030 onward (staged rollout)
- Rationale: Diversification, molten salt tech interest
Microsoft & Meta:
- Strategy: Bet on CEG existing nuclear (2025-2030)
- Rationale: Need power now, can’t wait for SMRs
Key Observation: Hyperscalers are hedging:
- Short-term (2025-2030): CEG existing reactors
- Long-term (2030+): SMR options
This validates CEG’s 5-10 year exclusive window.
4.4 Why SMRs Don’t Threaten CEG (Yet)
Timeline Reality:
SMR Commercial Readiness:
2025-2027: Engineering, permitting, early construction
2028-2029: First units commission (NuScale best case)
2030-2032: Volume production ramps
CEG Exclusive Window: 2025-2030 (5 years minimum)
During This Window:
- CEG can sign 10-15 GW additional PPAs
- Lock in 20-year contracts (extends to 2045-2050)
- Build customer relationships & operational integration
Post-2030 CEG Response:
- Deploy SMRs at existing sites (NRC license, grid connection advantages)
- Operate SMRs for hyperscalers (leveraging nuclear expertise)
- Worst case: 2030+ growth slows, but 2025-2030 contracts are locked
Investment Implication: CEG doesn’t need to “win forever”—just capture the 2025-2030 buildout, which is already happening.
