The energy transition continues to be one of the most durable and well-capitalized themes in private markets. Infrastructure fundraising has surged as institutional investors allocate to strategies offering long-duration cash flows, inflation protection, and exposure to decarbonization and digital infrastructure.

From multi-billion-dollar flagship closes to targeted mid-market vehicles, recent fundraising activity highlights how allocators are prioritizing scale, specialization, and resilience in energy transition investing. Below are some of the top infrastructure funds driving the energy transition based on recent fundraising momentum and strategic focus.

Why Infrastructure Leads the Energy Transition

Infrastructure has become a core allocation for institutional investors navigating an environment shaped by inflation, energy security concerns, and long-term decarbonization goals. Energy transition strategies (spanning renewables, grid modernization, storage, sustainable transport, and digital infrastructure) are now embedded across core, core-plus, and value-add infrastructure portfolios.

As capital continues to flow into the space, understanding which managers are raising capital and where they are deploying it has become increasingly important for allocators, fund managers, and advisors alike.

Top Infrastructure Funds Driving the Energy Transition

Manulife Investment Management – Flagship Infrastructure Fund

Manulife closed its $5.5 billion flagship infrastructure fund, exceeding target and signaling strong demand for core infrastructure strategies.

The fund focuses on essential infrastructure assets with stable cash flows, including renewable energy and energy-adjacent projects. For many institutional investors, this type of strategy provides defensive characteristics while still aligning with sustainability mandates.

Key takeaway: Core infrastructure remains a foundational allocation for energy transition exposure, particularly for pensions and insurers.

Apollo – Mid-Market Energy Transition & Digital Infrastructure

Apollo raised $2.4 billion for a mid-market infrastructure vehicle targeting energy transition and digital infrastructure projects.

Rather than focusing exclusively on large-scale assets, Apollo’s strategy highlights growing interest in mid-market transition opportunities, where operational improvements and platform build-outs can drive outsized returns.

Key takeaway: Amid the energy transition mid-market infrastructure has become an increasingly attractive deployment channel.

Meridiam – North America Infrastructure Fund IV

Meridiam collected over $1.8 billion for its North America-focused infrastructure fund, with a strong emphasis on sustainable and climate-resilient assets.

The firm’s approach centers on long-term public infrastructure, renewable energy, and sustainable mobility. The fund’s success reflects continued LP appetite for regionally focused, impact-driven infrastructure strategies.

Key takeaway: North American energy transition assets remain a priority as governments and corporates invest heavily in modernization and decarbonization.

What This Means for Allocators and Fund Managers

Recent infrastructure fundraising activity underscores several important trends shaping the energy transition:

Scale still matters, with mega-funds capturing large institutional commitments
Energy transition is now a core infrastructure theme, not a niche allocation
Mid-market and regional strategies are gaining traction alongside global platforms
Yield and downside protection remain critical, even as investors pursue sustainability goals

As allocators continue deploying capital into infrastructure, energy transition strategies are increasingly viewed as long-term portfolio anchors, offering predictable income today and structural growth tomorrow.
