Meta 20-year nuclear power deal explained in 60 seconds
Meta 20-year nuclear power deal explained in 60 seconds: here’s the short version. Meta signed a 20-year PPA with Constellation to buy the full output and clean energy attributes from the Clinton Clean Energy Center in Illinois, starting in June 2027, to power its AI-scale ambitions with always-on, carbon-free electricity.
The 60‑second explainer of Meta’s 20-year PPA nuclear energy deal
- Who and what: Meta signed a 20-year power purchase agreement (PPA) with Constellation for the Clinton Clean Energy Center’s entire output.
Sources: - Capacity and output: The plant delivers 1,121 MW after a 30 MW uprate (from ~1,092 MW), enough to power ~800,000 homes.
Sources: - Start date: Deliveries begin June 2027, coinciding with the end of Illinois’ Zero Emission Credit program for the plant.
Sources: - How it works: Power stays on the local grid; Meta buys the clean energy attributes to match its electricity use with carbon-free energy.
Sources: - Why it matters: It secures a reliable, 24/7 clean power source for AI data centers, preserves ~1,100 jobs, and contributes ~$13.5M in annual local tax revenue.
Sources: - Bigger picture: It’s Meta’s first nuclear deal and part of a broader tech trend as AI energy demand surges and companies pursue firm, zero-emission supply.

What Meta’s nuclear power deal 2025 actually covers
Meta’s 2025 agreement is a 20-year PPA for 1,121 MW from Constellation’s Clinton Clean Energy Center, starting in June 2027. The contract secures the plant’s continued operation and supports relicensing after state subsidies expire, effectively replacing policy support with a market-based commitment.
Under the deal, the plant keeps sending electricity to the regional grid while Meta purchases the clean attributes. This allows Meta to advance its 100% clean electricity goals without building new transmission to its data centers.
Clinton Clean Energy Center output and uprate details
Constellation lists Clinton’s single reactor at up to 1,092 MW and roughly 800,000 homes served. The Meta PPA enables an uprate to 1,121 MW, adding 30 MW of clean capacity without new concrete—small tweaks, big impact for regional reliability.
Importantly, the agreement positions Clinton for long-term operation. It transitions from the expiring Zero Emission Credit (ZEC) program to a private offtake, reducing closure risk and stabilizing output for decades.
Why did Meta sign a 20-year nuclear contract?
- AI energy demand and nuclear reliability: AI training and inference require round-the-clock power. Nuclear offers firm, carbon-free baseload that complements wind and solar, making it a strong match for data center reliability and emissions goals.
- Meta clean energy initiative: Meta already matches 100% of its electricity use with renewable energy and has contracted over 11,700 MW of clean energy globally. Nuclear adds 24/7, high-capacity credits that help balance intermittent resources as AI loads scale.
- Sector signal: Tech giants—including Meta—have pushed for tripling nuclear by 2050 and are striking long-term deals to unlock investment, relicensing, and expansions at existing plants.
Local impact: jobs, taxes, and grid reliability
Constellation says the PPA preserves about 1,100 high-paying local jobs and delivers roughly $13.5 million each year in tax revenue. The company also committed $1 million to local nonprofits over five years—a tangible lift for schools and services.
Because Clinton’s output remains on the grid (MISO zone 4), the region benefits from reliable, low-cost, zero-emission electricity. That’s crucial as electrification and AI-driven demand rise across the Midwest.
Timeline and what’s next for advanced nuclear at Clinton
Meta starts receiving energy attributes beginning June 2027. Between now and then, Constellation will pursue the uprate and relicensing steps that keep the plant operating for decades—now underpinned by market demand rather than state subsidy.
Looking ahead, Constellation is exploring pathways to add advanced nuclear, potentially small modular reactors (SMRs), at the Clinton site. That could future-proof the campus and add more firm, clean capacity as digital infrastructure grows.
Meta 20-year nuclear power deal explained in 60 seconds—key takeaways
- Firm clean power for AI: Nuclear gives Meta predictable, carbon-free electricity at scale, which intermittent renewables alone can’t guarantee.
- Clinton Clean Energy Center output: 1,121 MW with the uprate, from a proven Illinois reactor serving ~800,000 homes.
- Economic wins: ~1,100 jobs preserved, ~$13.5M annual taxes, plus community funding—without ongoing ratepayer subsidies.
- Start date: June 2027, synchronized with the end of Illinois’ ZEC support for Clinton.
- Bigger trend: Big Tech is locking in nuclear to meet surging AI energy demand and long-term decarbonization goals.
FAQ: Meta’s clean energy strategy for AI data centers
- Why did Meta sign a 20-year nuclear contract?
Answer: To secure 24/7, carbon-free power that can scale with AI data center demand, complementing its large wind and solar portfolio. - What is the capacity of the Clinton plant?
Answer: About 1,092 MW today, increasing to 1,121 MW with uprates enabled by the Meta PPA. - When will Meta start receiving power under this agreement?
Answer: June 2027, aligned with the expiration of the plant’s Zero Emission Credit program. - How will Meta’s deal impact local jobs and taxes?
Answer: It preserves roughly 1,100 high-paying jobs and contributes about $13.5 million in annual tax revenue, plus $1 million in local nonprofit support over five years. - Does the plant power Meta directly?
Answer: No. Clinton’s electricity stays on the regional grid; Meta buys the clean energy attributes to match its usage and cut its carbon footprint.
Conclusion
Meta 20-year nuclear power deal explained in 60 seconds boils down to this: a firm, zero-carbon lifeline for AI-era demand that stabilizes an essential Illinois plant, strengthens the regional grid, and drives local economic value.
