Global energy transition investment hit a record $2.3 trillion in 2025, according to BloombergNEF, and BNEF’s baseline scenario projects an average of $2.9 trillion per year over the next five years. Family offices, long underweight infrastructure relative to institutional peers, are now the marginal buyer of choice for grid, storage, and generation assets. BlackRock’s 2025 Global Family Office Survey confirms the shift: roughly one-third of family offices plan to increase infrastructure allocations into 2026, with energy transition exposure increasingly bundled into that bucket.

Key Takeaways
- BloombergNEF reports global energy transition investment reached $2.3 trillion in 2025, up 8% year-on-year, with electrified transport, renewables, and grid as the largest sectors.
- BlackRock’s 2025 Global Family Office Survey finds 30% of family offices plan to increase infrastructure allocations in 2025–2026, second only to private credit at 32%.
- Alternative assets now make up 42% of family office portfolios, up from 39% in 2022–2023.
- Climate-tech equity raised $77.3 billion in 2025, up 53% year-on-year — the first year of growth after three consecutive declines.
- Battery storage M&A transactions surged over 60% in 2025, signalling maturation of a once-speculative sub-sector.
Why Family Offices Are Repricing Energy Transition Risk
The asset class has matured. Power purchase agreements, regulated returns, and dollar-denominated cash flows make utility-scale renewables and grid assets a credible substitute for the bond allocations that lost real purchasing power during the 2022–2024 rate cycle. BloombergNEF puts energy transition debt issuance at $1.2 trillion in 2025, up 17%, giving private capital deep secondary markets to recycle into.
The demand side has also re-rated. US electricity demand rose 2% in 2025 — the first material increase in decades — driven largely by data-centre buildout: 23 gigawatts of capacity live in early 2025 with another 48 GW committed or under construction. AI compute is now an energy story, and family offices that previously held only AI equity are using infrastructure to capture the same thesis lower in the capital stack.
How Family Offices Are Actually Deploying
The BlackRock survey flags nuclear — including small modular reactors — as one of the most consequential long-term bets family offices are entertaining. Outside nuclear, the deployment pattern is barbelled: large family offices co-invest directly alongside Apollo, KKR, and Brookfield-style sponsors in operating renewable platforms, while smaller offices buy primary fund exposure or use listed YieldCos and infrastructure ETFs as building blocks.
Battery storage has graduated from venture territory to mid-market private equity, with a more than 60% jump in deal volume. Climate-tech equity’s $77.3 billion 2025 print includes meaningful HNWI capital in grid software, long-duration storage, and carbon-removal businesses, often via SPV structures that allow tax-loss harvesting against carried interest gains.
What This Means for HNWIs
For HNWIs and family offices, the headline number is the 70-basis-point average infrastructure exposure across surveyed family offices, with 79% reporting zero allocation. That gap, against a peer benchmark of 8–15% for large pensions and sovereign wealth funds, is the practical opportunity. Moving from zero to a 5–10% portfolio sleeve in regulated power, grid, and storage assets typically extends portfolio duration, dampens equity beta, and adds an inflation-linked income leg that complements existing private credit positioning.

Risks and Considerations
Energy transition is not a homogeneous trade. Subsidy regimes, interconnection queues, and offtake structures vary by jurisdiction, and US policy direction since the 2024 election has introduced incremental risk for clean-tech tax credits. Liquidity is the second concern: infrastructure funds typically carry 10–12-year lockups, and direct platform investments can be even longer. HNWIs should also evaluate operational risk — owning a wind farm is not the same as owning a bond — and ensure governance, insurance, and EPC counterparty quality match the size of the cheque.
Greenwashing and ESG-label drift remain reputational considerations, particularly for European family offices subject to SFDR-style disclosure. The most disciplined offices now run separate transition and conventional energy sleeves, recognising that hydrocarbons retain a role in portfolios until grid reliability catches up with demand growth.
The Bottom Line
The energy transition is no longer an ESG overlay — it is becoming a core infrastructure sleeve for family offices that need duration, inflation hedging, and exposure to the secular AI-and-electrification story. With $2.3 trillion deployed in 2025 and another $2.9 trillion per year projected through 2030, the question for HNWIs is no longer whether to allocate, but at what pace and through which vehicles.
