Summary
Institutional capital is pouring into co-located power generation and data centers. KKR and Energy Capital Partners committed $50 billion. Traditional project finance lenders are entering the sector. The PPA market is shifting from renewable-only to include nuclear and gas arrangements. Self-generation (behind-the-meter) is reshaping how deals are structured.
Major Capital Commitments
- Energy Capital Partners + KKR: $50 billion strategic partnership (announced July 2025) explicitly designed to develop and build co-located power generation and data centers.
- This is the single largest capital commitment to the power-for-AI thesis.

Project Finance Evolution
- Traditional project finance lenders are playing a growing role in data center power.
- Underwriting large, syndicated loans supported by:
- Long-term leases
- Stable power-supply arrangements
- Other risk-mitigation measures
- Can anchor billion-dollar developments.
- Structure increasingly resembles infrastructure project finance (long-dated, asset-backed) rather than tech venture.

PPA Market Shifts
- Corporate PPA market has long been dominated by renewables.
- Now seeing increase in nuclear PPAs as data centers try to procure firm baseload.
- 2024/25 saw high-profile PPAs between Big Tech and nuclear generators, concentrated in US.
- TotalEnergies signed a 15-year PPA with Google: 1.5 TWh certified renewable from Montpelier solar farm (Ohio), connected to PJM grid for data center operations.
- Question emerging: do traditional PPAs have a future in the data center sector, or will self-generation replace them?

Self-Generation as Dominant Model
- 48 GW of proposed data center capacity (33% of all planned) now includes behind-the-meter generation.
- Self-generation avoids grid interconnection queues and associated permitting.
- Shifts the deal structure: the data center operator is both customer and power plant owner/offtaker.
- Power plant becomes part of the data center capital stack, not a separate utility relationship.

Constellation Energy (Market Indicator)
- Wall Street maintains “Buy” or “Overweight” consensus on Constellation Energy (CEG) as of April 2026.
- Trading at $275.00 (April 1, 2026), roughly 30% retreat from October 2025 peak.
- Tone shifted from “euphoric” to “rational.”
- Constellation is a proxy for the nuclear-for-data-centers thesis.

Our Thinking (2026-04-05)
The $50B KKR/ECP commitment is the clearest institutional signal that co-located power + data centers is a multi-decade asset class, not a hype cycle. When private equity of this scale moves, it pulls infrastructure finance, insurance, and secondary markets behind it.
Three finance trends to track:
-
BTM changes the deal. When the data center owner also owns the power plant, traditional PPA structures evolve into something closer to integrated infrastructure finance. The “offtaker risk” disappears because the customer and generator are the same entity.
-
Nuclear PPAs are niche but symbolic. They signal that tech companies value firm baseload enough to sign 15-20 year nuclear contracts. But nuclear PPAs are still a small share of total data center power procurement.
-
Constellation’s 30% retreat suggests the market is repricing the nuclear-for-AI trade from euphoric to rational. Gas-for-AI (Williams, Bloom, NextEra) may be where the next wave of capital goes.
