NOMAD Power Solutions has received U.S. Department of Energy authorization to move the Vermont Long Duration Energy Storage Demonstration Project into Phase 3, shifting the program from planning into installation, integration, and construction. The project is expected to deploy up to eight transportable battery energy storage system units across five sites in Green Mountain Power's service territory. The approval is small in megawatt terms compared with the giant four-hour batteries now appearing in grid queues, but the operating question is different. NOMAD is testing whether utility-scale storage can behave less like a fixed power plant and more like reusable grid equipment that moves where the distribution system needs support. AI-generated image Transportable storage aims to make one battery asset useful across several grid jobs rather than one permanent interconnection point. What DOE just authorized NOMAD said the DOE Office of Electricity authorized the company, through its NOMAD Transportable Power Systems subsidiary, to proceed into Phase 3 under award DE-OE0000952. The approximately $19 million Vermont project is supported by a $9.5 million DOE award and an approximately 50 percent non-federal cost share, with reimbursements tied to cooperative agreement terms and milestones. The installation phase is expected to use NOMAD's latest platform, including next-generation lithium iron phosphate batteries and microgrid-enabled controls. The units are planned for sites inside Green Mountain Power territory, where rural communities have historically faced reliability issues during severe weather and utility work. $19M Approximate total project value 8 Planned transportable BESS units 5 Vermont deployment sites $9.5M DOE award supporting the project Green Mountain Power has already used an existing NOMAD system for peak management and to maintain service for customers during planned utility maintenance. That operating reference matters because transportable batteries are often described with a long list of possible applications. The Vermont project now has to show which of those applications can work together in a utility schedule. Why this is different from a normal BESS project A stationary battery is sized, interconnected, permitted, and monetized around one location. NOMAD's model asks whether the same asset can support peak shaving, outage response, planned maintenance, renewable integration, and microgrid service at different places over its operating life. The use case is distribution flexibility AI-generated image Rural and edge-of-grid circuits can need batteries for short windows, not always permanent installations. Most grid storage headlines are about transmission-scale assets. Those batteries sit at fixed nodes, bid into wholesale markets, and earn revenue from capacity, arbitrage, ancillary services, or tolling contracts. Distribution utilities face a messier set of needs. A feeder may need support during planned maintenance. A town may need backup after a storm. A substation may face a seasonal peak that does not justify permanent storage. A critical facility may need clean backup that can arrive faster than a new interconnection. Transportable storage tries to match that problem shape. If a battery can be redeployed with manageable permitting, interconnection, logistics, and operating rules, a utility can treat it as a shared resilience tool. The economics depend on utilization. A battery that avoids one diesel generator rental or one local outage is useful, but a battery that stacks several services across a year becomes more interesting. That stacking is also where the hard parts appear. Moving a BESS is not the same as moving a construction trailer. The asset needs grid-safe controls, utility procedures, trained crews, fire-safety planning, communications, maintenance records, and clear dispatch authority. Every site has its own protection settings and operating constraints. A mobile battery only becomes valuable if the operational burden is lower than the value it creates. Grid need How transportable storage can help What Vermont has to prove Planned maintenance Keep selected customers powered while crews work Repeatable setup and transfer procedures Seasonal peaks Discharge during high-cost local demand windows Enough utilization to justify asset movement Storm resilience Support remote circuits or critical loads after outages Fast deployment under real emergency constraints Microgrid operation Coordinate batteries, loads, and local generation Controls that work outside a lab environment Why LFP fits the job NOMAD says Phase 3 will include next-generation LFP batteries. That chemistry choice is not surprising. Lithium iron phosphate has become the workhorse for stationary storage because it offers strong cycle life, lower material-cost exposure than nickel-rich chemistries, and a safety profile that many storage developers prefer for large containerized systems. Mobile storage adds another reason to favor LFP. A transportable unit may face different duty cycles, weather exposure, siting requirements, and customer loads across its life. Energy density still matters, but the platform's practical value comes from durability, predictable thermal behavior, and simple maintenance. The battery has to be a field asset, not a fragile demonstration box. AI-generated image Mobile LFP systems must combine battery durability with utility-grade controls and straightforward field deployment. The DOE originally selected NOMAD's Vermont project in 2023 as part of a long-duration storage effort for remote communities and military housing. At the time, DOE described the Vermont award as a way to bring storage to rural communities that had faced unreliable electric service during severe weather. The new Phase 3 authorization matters because it takes that award into the field at a time when long-duration storage still needs more practical demonstrations outside investor decks and policy reports. Calling the project long-duration also deserves care. The industry often reserves that label for eight-hour, ten-hour, or multi-day storage. NOMAD's project is not competing directly with pumped hydro, iron-air, thermal storage, or flow batteries on multi-day bulk shifting. Its claim is more operational: if a transportable battery can cover a rural outage window, a maintenance window, or a local peak, duration becomes part of a broader resilience service. The commercialization test The Vermont deployment also lands during a reset for NOMAD itself. The company is now under NOMAD Power Solutions and trades on Nasdaq under NMAD. Industry coverage has noted the company's new ownership, recent product updates, UL 9540 certification for a 1 MW transportable system, and the need to prove commercial traction after years of development. For customers, the question is not whether a mobile battery can work once. It is whether utilities, cooperatives, data centers, municipalities, and industrial sites can buy or contract the asset with confidence. That means clear warranty terms, insurance, field service, dispatch software, spare parts, cyber-safe monitoring, and repeatable site engineering. A utility pilot can validate the product, but a commercial market needs a service model that makes deployment boring. AI-generated image The controls layer may decide whether transportable batteries become shared grid equipment or remain niche emergency assets. The strongest argument for the model is capital efficiency. Many distribution needs are real but intermittent. Utilities can struggle to justify permanent batteries at every vulnerable location, especially when local peaks and outage risks move around the system. A transportable fleet could let a utility buy fewer assets and extract more work from each one. The counterargument is that stationary batteries are easier to finance, interconnect, operate, and insure. A fixed project has a known site, a known revenue stack, and a
