Blackstone has successfully closed its fifth Blackstone Energy Transition Partners fund, securing $8.7 billion. This amount represents a 50% increase compared to the capital raised by the previous fund in the series. The firm intends to use these resources to scale energy companies capable of providing large volumes of cleaner power while enhancing the reliability and efficiency of energy infrastructure.
The new fund has already backed three entities: Kindle Energy, an independent power producer; Fisterra, a Spanish energy transition firm; and Viridon, a private power grid operator in the US. Additionally, Blackstone acquired three companies focused on infrastructure sustainability: Flow Control, which supplies liquid cooling components for data centers; Dresser Utility Solutions, a manufacturer of measurement and repair equipment; and DarkVision, a developer of industrial inspection technologies.
Blackstone is simultaneously exiting several mature investments. The firm sold Aypa Power, a battery storage operator, and divested its controlling stake in infrastructure manufacturer Sabre Industries. Furthermore, the company completed the IPO of Legence, a firm specializing in engineering and installation services for data centers. These moves reflect a broader strategy to reallocate capital toward emerging energy demands.
Data center infrastructure remains a primary focus for the firm. In 2026, Blackstone completed the IPO of its data center real estate trust and announced a $5.34 billion investment in Williams. This capital will fund five behind-the-meter power generation projects designed to meet the rising electricity needs of North American data centers.
Despite these efforts, some initiatives face delays. In September, reports emerged regarding the postponement of Project Braid, a collaboration with Google. The project aimed to build a cloud platform utilizing Google Tensor Processing Units. Blackstone had planned to invest $5 billion, with a target of bringing 500 MW of capacity online by 2027, though the timeline for this development has shifted.
