POWER UP

What POWER UP does

Power Up Connect LLC is a Baltimore, Maryland-based designer and manufacturer of mobile battery energy storage systems (MBESS) and portable charging solutions, operating from a single facility at 539 N Dean St. The company's core products are the Green Grid 90kWh MBESS (a UL 9540/9540A-certified, International Fire Code-compliant trailer-mounted system delivering 90 kWh capacity and 20 kVA continuous output) and the Green Grid Mini (a 20 kWh compact unit), both built on LiFePO4 battery chemistry with integrated solar inputs, grid-interactive inverters, sub-20ms UPS transfer, daisy-chain capability for up to nine trailers, and cloud-based remote telemetry. A complementary Multimedia Charging Trailer (dual-axle, 1,100W solar, 20kW LFP storage, RFID lockers, dual 55-inch displays, optional Starlink) and add-on modules (UVC charging carts, solar charging tables, charging lockers, wall-mounted stations, Power Up Analytics software, Power Up Care+ service) round out a diversified portable power and device-charging portfolio.

The company sells primarily through direct enterprise sales to utilities, emergency management agencies, construction firms, healthcare facilities, telecom operators, and EV infrastructure providers, with custom design orders starting at $50,000+ and standard terms of NET 30 (custom products requiring 100% pre-payment with no returns). Hardware sales are augmented by USA-only equipment rentals, limited lifetime warranty service contracts, and on-site/off-site professional services. Geographic reach spans North America, South America, Europe, and Africa on the sales side, while rentals remain domestic. Key commercial milestones include the September 2025 launch of the Green Grid 90kWh, the January 2026 ribbon-cutting deployment with Dominion Energy at its Safety and Training Center in Chesterfield, Virginia, and selection into the 2026 ChargeUp Accelerator cohort at Binghamton University's Koffman Southern Tier Incubator.

Operationally, Power Up Connect is a small privately held LLC (1–10 employees, founder Scott Calhoun) with no disclosed institutional investors, no public revenue disclosure, and only $25,000 of identified accelerator funding to date. Its value proposition centers on displacing diesel generators with zero-emission, near-silent mobile power capable of delivering 87% fuel reduction and 70% cost savings, while meeting the fire safety and interconnection standards (UL 9540, UL 9540A, UL 1973, UL 1741SA, IFC compliance) required by regulated utility and government buyers.

Direct peers

• Moxion Power: Mobile, trailer-mounted battery energy storage systems targeted at construction sites, events, and EV charging — the closest direct head-to-head competitor to Power Up Connect's Green Grid product line.
• Nomad Transportable Power Systems: Trailer- and skid-mounted mobile BESS units used for utility outages, construction, and events; directly comparable product form factor and customer set.
• FreeWire Technologies: Mobile and stationary EV charging solutions with integrated battery buffering; competes directly with Power Up's mobile EV charging offering and shares the mobile battery-buffered charger category.
• SparkCharge: Portable, battery-buffered DC fast-charging units for EVs deployed at fleet depots, roadside events, and infrastructure-light sites; overlaps with Power Up Connect's mobile EV charging use cases.

Emerging players

• BLUETTI: Portable and home LiFePO4 power stations with strong brand and retail presence; competes at the smaller-capacity, mass-market end of portable energy storage rather than trailer-scale utility mobile BESS.
• EcoFlow: Portable power stations and large-format mobile battery products for consumer, prosumer, and light-commercial use; partial overlap with Power Up's lower-capacity and EV-charging-adjacent offerings.
• Goal Zero (NRG Energy / Provo Labs): Portable solar generators and integrated mobile power products serving outdoor, emergency, and off-grid use cases that intersect with Power Up's disaster response and event applications.
• Lion Energy: Portable and expandable LiFePO4 power systems for outdoor, emergency, and small-business backup; comparable portable-LFP chemistry focus to Power Up's Green Grid Mini.

Broad incumbents

• Generac: Established backup power and mobile generator manufacturer; overlaps with Power Up's mobile power mission but addresses it primarily through combustion and stationary products rather than mobile BESS.
• Tesla Energy: Powerwall, Megapack, and Supercharger ecosystem; a much larger incumbent across stationary storage and EV charging that could credibly expand into mobile/utility-temporary BESS.
