ABM Announces Aacon-Ravenvolt JV Selection by U.S. Army Corps of Engineers for Energy Resilience Microgrid at White Sands Missile Range

Project will integrate solar, battery storage, and on-site generation to strengthen mission readiness amid grid outages and other disruptions

LOUISVILLE, KY / NEW YORK - November 3, 2026 - ABM (NYSE: ABM), a leading provider of facility, engineering, and infrastructure solutions, in coordination with joint venture partner AACON General Contractors, today announced that AACON-RavenVolt JV, LLC has been awarded a construction contract by the U.S. Army Corps of Engineers (USACE) Louisville District to construct an advanced microgrid at White Sands Missile Range in New Mexico. RavenVolt is ABM's energy solutions subsidiary.

Awarded under the Department of Defense's Energy Resilience and Conservation Investment Program (ERCIP), the project will combine solar power, battery energy storage, on-site backup generation, and advanced controls to safeguard mission-critical military operations against external grid outages, extreme weather events, and power disruptions.

"Reliable power is fundamental to mission readiness, and critical military installations require robust, modern infrastructure to guarantee continuous operation," said Mark Hawkinson, President, Engineering & Infrastructure Solutions, ABM. "Through the combined strengths of AACON General Contractors and RavenVolt, the AACON-RavenVolt joint venture is proud to partner with the U.S. Army Corps of Engineers Louisville District to deliver a resilient power system engineered to sustain White Sands Missile Range when the commercial grid cannot."

Constructed under a Design-Bid-Build framework, the secure feeder-level microgrid will integrate a carport-mounted solar photovoltaic (PV) array, a high-capacity battery energy storage system (BESS), dispatchable on-site generators, and an intelligent microgrid control system. Working as a single, coordinated system, these distributed energy assets will allow the installation to seamlessly island, reduce dependence on the local utility grid, and provide redundant power to vital cantonment area facilities. The scope also includes new electrical distribution lines, fiber optic communications, and security infrastructure.

The White Sands Missile Range award demonstrates AACON-RavenVolt JV, LLC's specialized capability in delivering complex federal energy resilience and mission-critical infrastructure projects.
