KKR has agreed to invest up to A$600 million ($603 million) into HMC Capital’s Energy Transition Platform, marking a major institutional bet on battery storage and wind infrastructure as Australia’s electricity system undergoes rapid structural change.

The investment introduces KKR-managed funds as a long-term partner alongside HMC Capital in a platform that currently comprises 652 MW of operational assets and a 5.7 GW development pipeline spanning battery energy storage systems and wind projects. The transaction is expected to close in mid-2026, subject to customary regulatory approvals.

Scaling Storage and Wind to Stabilize a Changing Power System

The deal comes as Australia faces mounting grid stability challenges driven by coal plant retirements, accelerating renewable penetration, and rising electricity demand. Policy priorities have increasingly shifted toward flexible infrastructure capable of balancing intermittent wind and solar generation while maintaining system reliability.

Battery storage, in particular, has emerged as a critical asset class within Australia’s energy transition, enabling rapid response to demand fluctuations and supporting grid security as renewable capacity expands across the National Electricity Market.

KKR Expands Climate Transition Strategy in Australia

KKR is funding the investment through its Global Climate Transition strategy, which has committed more than $44 billion to climate and environmental sustainability investments since 2010. The transaction represents KKR’s second climate-focused investment in Australia, following its earlier backing of distributed energy platform CleanPeak.

Neil Arora, Partner and Head of KKR’s Climate Transition strategy for Asia, said Australia’s energy system is approaching a pivotal phase, where investment in flexible infrastructure such as battery storage will be essential to sustaining grid reliability alongside renewable growth. He added that KKR’s global operating experience and climate investment platform position the firm to help scale HMC’s portfolio and support Australia’s decarbonization objectives.

Building a National-Scale Energy Transition Platform

HMC Capital described the partnership as a validation of its strategy to develop a large-scale, integrated clean energy platform capable of meeting future electricity demand from households, industry, and emerging AI-driven workloads.

David Di Pilla, Managing Director and CEO of HMC Capital, said the investment would enable the platform to materially expand operating capacity and cash flow while accelerating progress across its development pipeline. He noted that the partnership strengthens HMC’s ambition to play a central role in Australia’s transition to net zero emissions by 2050.

Governance and Long-Term Energy Policy Alignment

Julia Gillard, former Australian Prime Minister and Chair of the Energy Transition Platform, framed KKR’s entry as a milestone in building a nationally significant renewables business. She said the partnership brings global expertise and capital depth that will help position the platform as a leading contributor to Australia’s clean energy commitments.

A Broader Signal for Global Energy Transition Capital

The investment reflects a wider shift among institutional investors toward assets that deliver dispatchable flexibility rather than solely generation capacity. As electrification expands across transport, industry, and digital infrastructure, grid-scale storage and hybrid renewable platforms are increasingly seen as foundational to energy security.

KKR’s global climate portfolio already includes battery storage developer Zenobē in the UK, solar-plus-storage developer Avantus in the United States, energy services provider EGC in Germany, and industrial decarbonization platform IGNIS P2X in Spain. Together, these investments highlight a strategy focused on infrastructure that aligns long-term contracted revenues with climate policy objectives.

For policymakers, utilities, and investors, the Australia transaction underscores how climate policy, grid resilience, and institutional capital are converging around flexible energy infrastructure as a defining theme of the global energy transition.
