Phinergy and Rosendin Unlock New Grid Capacity for Data Centers

Second white paper positions aluminum-air generation as a strategic flexibility tool for AI-era infrastructure

  • Grid flexibility for just 1 percent of the year could unlock 70 gigawatts of new U.S. data center capacity
  • Onsite aluminum-air generation helps data centers connect to the grid sooner while preserving full emergency-backup capability
  • Follows completion of Phinergy’s Net Zero Innovation Hub milestone validation toward full scalability

SAN JOSE, Calif. (November 2, 2026) – Phinergy (TASE: PNRG), a publicly traded clean energy technology company, released its second white paper in collaboration with Rosendin Electric, one of the largest electrical contractors for data centers in the United States. Titled “From Backup Power to Grid Enabler: Use Cases for Aluminum-Air Generator (AAG) in AI-Era Data Centers,” the paper shows how the AAG turns backup power into a grid-flexibility resource.

The paper arrives as data center demand collides with mounting pushback over diesel generator permits, exhaust, noise and strain on local grids. Northern Virginia alone has more than 9,000 backup diesel generators serving data centers, prompting state lawmakers to debate stricter clean-energy requirements, according to Virginia Mercury. More than 45 states now have moratoriums or restrictions affecting new data center development, forcing operators, contractors and infrastructure planners to seek clean alternatives that match the reliability of diesel without the environmental and community costs.

At the same time, access to power has become the primary constraint on data center growth, as utilities often can’t deliver the full capacity operators request because the grid must be sized for a limited number of peak-demand hours. The AAG addresses both challenges, delivering clean backup power while acting as a grid-flexibility resource that helps operators secure capacity sooner, positioning aluminum-air generation as a strategic tool for the AI era.

Leadership Perspective

“The AAG is a single asset that delivers multiple services simultaneously,” said Emmanuel Levy, CEO, Phinergy. “It accelerates speed-to-power by helping data centers jump ahead of the interconnection queue, while providing clean, quiet, community-friendly backup power. Our recent module completion milestone through the Net Zero Innovation Hub for Data Centers moves us one step closer to full scalability and proves that aluminum-air technology is ready to meet the demands of hyperscale operators at every level today.”

Building on Proven Research

The first white paper, “Aluminum-Air Generator for Data Centers,” established the technical and commercial case for aluminum-air generation as a direct replacement for diesel generators, documenting its zero-emission profile, multi-day runtime, compact footprint and ability to integrate into existing data center architectures. The second paper builds on that foundation by expanding into three detailed use cases: clean backup power for AI inference and cloud, unlocking additional grid capacity in power-constrained markets, and an on-demand resilience layer for renewable microgrids. It also provides a direct comparison between the AAG and alternative solutions including diesel generators and lithium-ion battery systems.

A Partner Perspective From Rosendin

“Data center clients are asking for power solutions that reduce environmental impact without sacrificing uptime, and the AAG delivers on both,” said Bill Mazzetti, Senior Vice President, Rosendin Electric. “Projects have always demanded clean, quiet and resilient on-prem power. Aluminum-air generation clearly checks all these boxes. Sometimes you have to change older design and specification habits for something new that clearly solves stringent planning and local conditions for development while also offering quick-to-market, large-scale systems.”

Industry Context

U.S. data center electricity consumption could reach 380 to 790 terawatt-hours by 2030, representing 9 to 17 percent of total U.S. electricity consumption, according to EPRI’s Powering Intelligence 2026 report. The same agency also finds that if data centers reduce grid demand for just 1 percent of annual operating hours, existing U.S. electricity systems could integrate up to 70 gigawatts of new data center capacity without a single grid upgrade. The AAG makes that flexibility operational and available today.

How can data centers connect to the power grid faster when utilities can't deliver full capacity?
Phinergy’s aluminum-air generator helps data centers jump ahead of the interconnection queue by acting as a grid-flexibility resource that reduces peak demand on the grid. According to a white paper released by Phinergy and Rosendin Electric, if data centers reduce grid demand for just 1 percent of annual operating hours, existing U.S. electricity systems could integrate up to 70 gigawatts of new data center capacity without a single grid upgrade. This positions aluminum-air generation as a strategic tool for operators in power-constrained markets seeking faster speed-to-power.

How does clean backup power technology address increasing state restrictions on diesel generators at data centers?
More than 45 states now have moratoriums or restrictions affecting new data center development, largely driven by concerns over diesel generator emissions, noise, and strain on local grids. Phinergy’s aluminum-air generator delivers clean, quiet, community-friendly backup power as a direct replacement for diesel generators. Rosendin Electric, one of the largest electrical contractors for data centers in the United States, has validated the AAG as a solution that meets stringent planning and local conditions for development.

What alternatives to diesel generators are available for data center backup power?
A white paper released by Phinergy and Rosendin Electric compares the aluminum-air generator directly against diesel generators and lithium-ion battery systems as backup power options for data centers. The AAG offers a zero-emission profile, multi-day runtime, compact footprint, and the ability to integrate into existing data center architectures. Unlike diesel generators, Phinergy’s AAG operates cleanly and quietly, making it compatible with increasingly strict state and local environmental requirements.

How can data center operators reduce environmental impact without sacrificing uptime or reliability?
Phinergy’s aluminum-air generator is designed to deliver clean backup power while maintaining the reliability that data center operators require for AI inference and cloud workloads. Rosendin Electric Senior Vice President Bill Mazzetti confirmed that data center clients are asking for power solutions that reduce environmental impact without sacrificing uptime, and the AAG delivers on both. The technology provides clean, quiet, and resilient on-premises power, according to Rosendin Electric.

What impact will rising AI workloads have on U.S. grid infrastructure and data center power demand?
U.S. data center electricity consumption could reach 380 to 790 terawatt-hours by 2030, representing 9 to 17 percent of total U.S. electricity consumption, according to EPRI’s Powering Intelligence 2026 report cited by Phinergy.
