Blackstone and Halliburton have invested $1 billion into VoltaGrid, a company that builds gas-powered microgrids for data centers. The investment, which values VoltaGrid at over $10 billion, includes an acquisition of Propell Technologies Group to bolster operations.
Why it matters
VoltaGrid provides technology companies with faster access to electricity for AI systems, addressing the power constraints currently stalling data center expansion. The deal underscores the role of independent microgrid infrastructure in supporting the scaling of large-scale computing.
VoltaGrid maintains a 7.5 gigawatt order book, a significant pipeline of projects relative to typical utility-scale deployment timelines. The firm projects its annual EBITDA will reach $1.1 billion by 2028.
The players
Blackstone
An alternative asset manager focused on real estate, private equity, and infrastructure investments.
Halliburton
An oilfield services corporation with a market capitalization of approximately $33 billion.
VoltaGrid
A Houston-based firm specializing in modular microgrid infrastructure for power-intensive data centers.
Propell Technologies Group
An industrial services firm being acquired by VoltaGrid to integrate its 800-person workforce.
The details
VoltaGrid deploys gas-powered microgrids—localized, small-scale electrical grids that operate independently from the main utility network—to supply high-density data centers. By acquiring Propell Technologies Group and its 800-person workforce, VoltaGrid intends to reduce the execution risk associated with physical infrastructure deployment. The injection of $775 million in new equity and $225 million in secondary purchases provides the capital necessary to accelerate these energy projects.
Timeline
September 2026: Blackstone and Halliburton announced the investment.
2024: The current period for annual EBITDA reporting.
2028: The target year for reaching $1.1 billion in annual EBITDA.
Through 2030: The duration covered by the current 7.5 gigawatt order book.
The Tech Race
The investment represents a major shift toward private, off-grid power solutions for the tech sector. It follows a pattern where companies are increasingly bypassing traditional utility timelines to secure dedicated power through localized microgrid infrastructure.
This deal secures the energy foundation for future data center projects that will ultimately host the next wave of AI platforms. Readers in industries reliant on large-scale compute should expect shorter lead times for power availability as these microgrids scale.
The takeaway
The move signals a transition toward data center developers owning their own power generation to bypass grid congestion. Watch for VoltaGrid to report its 2028 EBITDA targets as a measure of the effectiveness of this infrastructure rollout.
