Blackstone has announced the final close of Blackstone Energy Transition Partners V (BETP V) at $8.7 billion, making it more than 50 per cent larger than its predecessor fund.

The vehicle was significantly oversubscribed and reached its hard cap, reflecting investor demand for the firm’s energy transition investment strategy.

Blackstone Energy Transition Partners (BETP) focuses on building large-scale energy businesses that support growing global demand for cleaner, more reliable and affordable energy.

As of June 30, the strategy had generated a 34 per cent net internal rate of return (IRR) since 1997.

In 2025, BETP was named Fund Manager of the Year – Equity for North America by IJ Investor.

David Foley, Global Head of Blackstone Energy Transition Partners, said: “We believe there is a generational opportunity for experienced investors in the energy transition to provide solutions to the challenges posed by growing demand for electricity. By backing exceptional management teams with flexible, patient equity capital to increase manufacturing capacity, recruit and train skilled labour and construct new critical energy infrastructure assets, BETP is delivering those solutions and in the process building these companies to scale, creating jobs and generating lasting value for our investors. We are deeply grateful for the trust of our investors and look forward to deploying BETP V in investments that advance the transition to a more affordable, reliable and cleaner energy future.”

BETP V began its investment period in June and has already funded three platform companies: Kindle, Fisterra and Viridon.

These investments support the development and operation of new power generation capacity and electricity transmission infrastructure.

The fund has also completed three acquisitions focused on energy efficiency and infrastructure resilience: Flow Control Holdings, a US provider of engineered flow-control components for data centre liquid cooling; Dresser Utility Solutions, which supplies measurement, control and repair products for gas and water utilities; and DarkVision, a technology-enabled inspection services provider for critical energy infrastructure.

Since January 2025, BETP has committed more than $11 billion in new equity investments across the energy transition sector.

Investments include power equipment manufacturers such as Maclean Power Systems and Delta Star, essential services providers Alliance Technical Group and Shermco, energy analytics company Enverus, and natural gas-fired power infrastructure projects.

The firm has also monetised several mature investments in predecessor funds.

These include an agreement to sell Aypa Power, which has a 6.0-gigawatt battery storage portfolio; the sale of a majority stake in infrastructure manufacturer Sabre Industries; and the initial public offering of Legence, a provider of engineering and mechanical contracting services for data centres, healthcare and other specialised commercial and industrial markets.

The fund’s close and investment activity highlight BETP’s continued focus on energy generation, grid infrastructure, efficiency and reliability. -OGN/TradeArabia News Service
