Managers are raising large sums to build the power systems the world needs. The binding constraints are now security of supply, access to the grid and the price paid for assets everyone wants to own.
Demand Is Not the Question
Energy infrastructure has rarely had a stronger demand story. The International Energy Agency expects global energy investment to reach $3.4 trillion in 2026, with investment in electricity supply and infrastructure reaching nearly $1.6 trillion. Spending on grids alone is projected to approach $550 billion, up nearly 20% year-on-year. Fundraising reflects the same conviction: Blackstone’s latest energy transition fund reached its $8.7 billion hard cap one year after launch.
What matters for investors is whether that demand can be served profitably. Three issues recur in expert reports and manager commentary: a security shock that is repricing risk, a grid that has become the gating asset, and a market where abundant capital is compressing returns while financing costs stay high. Together they suggest that execution, not access to capital, now separates good outcomes from poor ones.
Security Comes First
The IEA’s World Energy Investment 2026 report, published in May, opens with an unusually blunt assessment. Executive Director Fatih Birol called the moment “the largest energy security crisis the world has ever faced” and expects it to reshape investment strategies in the way the 1970s oil shocks did. The agency ties the crisis to the effective closure of the Strait of Hormuz and says it is changing risk perceptions and bolstering diversification. It also cautions that prioritising security will add costs and may trade off against affordability.
For infrastructure investors, that has two consequences. The first is that geopolitical exposure is now an underwriting input rather than a footnote. Aon’s 2025 survey of infrastructure investors, discussed last December and so before the Gulf crisis, found that 68% cited geopolitical tension as the largest challenge to deploying capital, while 32% called it the dominant driver of buy and sell appetite. Aon managing director Corey Lewis said investors were explicitly pricing geopolitics into required returns and, in some cases, avoiding regions where permitting, interconnection or national-security review could create execution friction. Events since have only strengthened that logic.
The second consequence is that security reshapes relative value rather than simply lowering it. In the same period, Stonepeak, a North America-focused investor, argued that the geopolitical situation increases the value of US energy assets. Exposure is not evenly spread, and neither are the returns it commands.
The Grid Has Become the Asset
If security is the new risk premium, the grid is the new bottleneck. On its second-quarter call, Brookfield Renewable’s management told investors that global electricity demand is accelerating and “there is simply not enough new capacity coming online to keep up,” while grid infrastructure is not being developed quickly enough.
The hardware tells the same story. BloombergNEF data show lead times for large transformers of 100 MVA and above have more than doubled since 2019, and US prices have climbed 79%. Specialised factory equipment can take two to four years to procure. Queues are equally stretched. Berkeley Lab data counted roughly 10,300 US projects seeking interconnection at the end of 2024, representing 1,400 gigawatts of generation and 890 gigawatts of storage. In Britain, Minesh Shah of The Renewables Infrastructure Group notes that the connection queue had swollen to more than 700 gigawatts before 2025 reforms, four times what the system needs for 2030. Reform has cut it, but building enough grid to connect new generation remains a huge undertaking.
For valuation, this changes what is actually being bought. Lewis said interconnection queues are delaying commercial operation dates and reducing valuation certainty, and that buyers are discounting assets with ambiguous interconnection rights or upgrade costs. In his words, “grid access is becoming as valuable as the underlying asset itself.” Large sponsors pursuing multi-gigawatt pipelines face added execution risk because those pipelines depend on long-lead substation and transmission upgrades.
Some investors are working around the constraint. Brookfield Infrastructure described a $5 billion strategic partnership to install up to 1 GW of behind-the-meter power. Brookfield’s 2026 outlook argues that behind-the-meter generation shortens time-to-power and bypasses grid bottlenecks. The workaround has its own trade-offs, but it shows how far the grid has moved from background infrastructure to the main variable in project timing.
Abundant Capital, Thinner Margin for Error
Capital is not the scarce input. In Aon’s survey, 92% of respondents still expected valuations to rise, driven primarily by deployment pressure from accumulated dry powder rather than improving fundamentals, and 40% named that pressure the principal driver of uplift over the next 12–24 months. Yet selectivity is increasing. Lewis said investors are assigning materially higher multiples to assets with secure power access, predictable construction timelines and clear permitting, interconnection and policy visibility, so valuation dispersion is widening.
Manager commentary shows the same split. Stonepeak’s Jack Howell observed that traditional energy assets are being well bid while renewable assets are out of favour: “nobody wants to touch them.” Blackstone’s David Foley frames the market more optimistically, describing “a generational opportunity for experienced investors in the energy transition” as demand for electricity grows. The word “experienced” is doing real work in that sentence.
Meanwhile, the cost of money has not eased. A Sidley review of first-half 2026 activity found that persistent inflation, elevated debt costs and expectations of prolonged higher interest rates, alongside Middle East tensions, were holding back M&A even as infrastructure fundraising stayed relatively strong. The OECD projects G20 inflation of 4.1% in 2026 and warns that energy disruptions, extreme weather, higher bond yields and weaker returns on AI investment could together cut global growth by 0.7 percentage points in 2027. Buyers paying full prices for long-dated cash flows are therefore betting on a smoother financing backdrop than the evidence currently supports.
What to Ask Before Committing
For limited partners and allocators, the practical response is to turn these three issues into diligence questions. Which assets in the pipeline hold secured interconnection rights, and how much underwritten value depends on grid upgrades that have not yet been built? How exposed are construction schedules to transformer and equipment shortages? Where does the portfolio rely on shipping routes, chokepoints or jurisdictions that national-security review could complicate? Advocates for pension investors have urged LPs to ask GPs how returns would hold up through disruption at energy chokepoints.
On price, the questions are just as direct. What entry multiple is being paid, and what does the return look like if financing costs stay where they are and exits take longer? Lewis expects that in 2026, execution capability rather than capital availability will be the key differentiator among infrastructure investors. Managers who can show secured connections, protected supply chains and disciplined pricing deserve more confidence than those leaning on the strength of the theme alone.
The defining question for energy infrastructure investors is no longer whether the capital is there. It is whether the power can be delivered, connected and sold at a price that justifies what was paid for it.
