VoltaGrid secures $1B strategic equity from Blackstone, Halliburton

VoltaGrid has signed agreements for a $1 billion strategic equity investment led by funds managed by Blackstone and Halliburton, marking one of the largest recent capital commitments to behind-the-meter power infrastructure for data centers and industrial users. The deal consists of approximately $775 million in primary capital injected into VoltaGrid and a $225 million secondary purchase of shares from existing investors, providing both growth funding for the company and liquidity to current shareholders. The transactions were announced in mid-May 2026, with closing expected around mid-2026, and will support accelerated deployment of VoltaGrid’s modular natural gas generation and microgrid solutions for data centers, microgrids, and broader industrial applications.

The new capital positions VoltaGrid to scale its behind-the-meter natural gas generation assets, which are designed to provide dispatchable on-site power tailored to the surging energy demand from AI and hyperscale computing facilities. According to deal disclosures, Goldman Sachs & Co. acted as financial advisor to VoltaGrid, while Blackstone was advised by Morgan Stanley and Lazard. Blackstone is contributing the majority of the equity through its infrastructure and energy transition-focused vehicles, and Halliburton is joining as a strategic partner, bringing operational expertise in remote power systems and access to gas-related equipment and supply chains. Although the parties did not disclose VoltaGrid’s valuation, the scale and structure of the $1 billion equity commitment underscore investor confidence in behind-the-meter generation as a critical enabler for the next wave of data center and industrial growth.
