US Army Research Lab Forward-Deployed Microgrid Programs Include Medium-Voltage Solid-State Transformers

US Army Research Lab forward-deployed microgrid programs have included medium-voltage solid-state transformer (SST) work as a sub-element of the broader Mobile Electric Power program portfolio. The connection has not been the subject of dedicated public press releases but is visible through SAM.gov contract awards, DEVCOM Ground Vehicle Systems Center disclosures, and the trade-press coverage of programs adjacent to the SST core. The Army’s interest in SST technology centers on three operational requirements specific to expeditionary energy: rapid deployment, harsh-environment thermal performance, and bidirectional power-flow management for forward-deployed microgrids that combine generators, battery storage, and intermittent renewables.

The Mobile Electric Power program at the Army Corps of Engineers and DEVCOM has historically procured conventional generator sets, ruggedized switchgear, and tactical microgrid controllers from incumbent suppliers including Caterpillar, Cummins, MTU, and Eaton. Eaton’s August 2025 acquisition of Resilient Power Systems brings an MV-SST capability into Eaton’s defense-aligned product portfolio for the first time. The intersection between forward-microgrid procurement and SST product availability is therefore newly aligned.

The mgrid coverage of the Parsons Corporation $2 billion Army Corps energy resilience contract (pid 8624) and the broader Army Corps $2 billion 10-year IDIQ pipeline (pid 8651) documents the scale of US Army microgrid procurement that the SST industry is positioning against. The annual contract flow exceeds $200 million in microgrid-relevant capital procurement, with a multi-year multiplier as forward-deployment operational tempo varies.

The technical case for SSTs in forward-deployed microgrids is straightforward. A single mobile chassis containing an MV-SST plus integrated power-quality compensation replaces three or four conventional distribution-class units. The footprint, weight, and transport-aircraft compatibility advantages map directly to expeditionary requirements. The cost premium per kVA is partially offset by the elimination of the auxiliary equipment a conventional architecture would require.

The Army Research Lab’s explicit SST roadmap has not been publicly disclosed. Several SBIR Phase I and Phase II contract awards to small US power-electronics firms have included SST-relevant scope, and the broader DOE-DOD SBIR cross-coordination program has emphasized wide-bandgap semiconductor research that overlaps directly with SST device requirements. Whether the Army eventually selects a single MV-SST product line for general forward-deployment use or maintains a multi-vendor procurement posture is the unresolved strategic question.

Why It Matters

For defense-energy planners, the Army Research Lab’s forward-deployed microgrid work brings medium-voltage SSTs into expeditionary power, where rapid deployment, harsh-environment thermal tolerance, and bidirectional flow are hard requirements rather than nice-to-haves. Military qualification tends to precede commercial ruggedization, so equipment proven under these conditions can later lower the risk perception for civilian critical-facility microgrids.

Critical Perspective

Editorial correction: This post is part of MGRID’s Solid-State Transformer industry coverage. As of May 2026, that body of work systematically framed manufacturer announcements, funding rounds, and laboratory demonstrations as commercial deployments. The reality is that field-deployed commercial-class SST in revenue service globally is measured in single digits, and almost every product cited in this series is at “announced” or “funded” stage, not “operational.” Readers should treat the specific claims in this post against the standards documented in our SST Industry Reality Check (the per-claim audit table maps marketing language to verifiable deployment status). The corrective article is the canonical reference for SST industry reality; this post remains published with its original framing so the editorial drift is traceable.
