Company profile
researched Aug 2026VoltServer Inc. designs and manufactures fault-managed power (FMP) transmission products sold under the Digital Electricity brand. The patented approach transmits electricity as small pulses, or "packets," that are individually checked for safety and can carry embedded data, allowing power at hundreds of volts and thousands of watts to be distributed in a form the company describes as not harmful to human touch and without producing a fire hazard, with hazardous current interrupted within milliseconds. Systems combine hardware transmitters and receivers with monitoring and control software.
Power can be run through existing data pathways or in hybrid cables alongside fiber optics, which the company positions as reducing installation disruption, permitting requirements in some regions, commodity cost and electrical room footprint. VoltServer markets integrated end-to-end systems across six industry segments: service provider networks (5G and Wi-Fi remote power), transportation networks, enterprise buildings and campuses, industrial and manufacturing, data centers, and building electrification. Recent published material focuses on using Digital Electricity to add AI server racks to operational data centers with limited disruption and on the role of fault-managed power in AI infrastructure cost management.
The company is headquartered in East Greenwich, Rhode Island, and works through power and connectivity partners, including a partnership with Eaton aimed at critical infrastructure.
Founding story
Founder and CEO Stephen Eaves, who previously founded Modular Energy Devices (ModEnergy), a lithium-ion battery supplier to the telecom industry acquired by EnerSys in 2011, and who holds 15 issued or pending patents in energy storage and power conversion, set out to make electricity inherently safe. Drawing on more than 20 years in the industry, he incorporated VoltServer in 2011. Dan Lowe is listed as co-founder and Chief Business Officer, with a background in carrier Internet infrastructure companies including Arris Networks and Redstone Communications.
Business model
VoltServer manufactures and sells fault-managed power transmission hardware and accompanying monitoring and control software, delivered as integrated end-to-end systems in conjunction with power and connectivity partners and third-party manufacturers that integrate the technology into their devices.
Sales of Digital Electricity hardware systems and associated software for power distribution deployments.
Traction
As of the April 2023 Series B announcement, the company reported tens of thousands of installed circuits in buildings including NFL stadiums, smart hotels and indoor vertical farms. The company's history page states Digital Electricity powers over 1,000 large sports stadiums, office towers, hotels, condominiums and medical buildings; an earlier about page cited over 700 large venues and intelligent buildings.
Latest developments
The company promotes a partnership with Eaton to bring Digital Electricity to critical infrastructure and has published material on applying fault-managed power to AI data centers, including low-disruption installation of AI server racks in operational facilities.
▸Full profile — market position, technology, go-to-market, geography, history
Market position
VoltServer describes itself as the inventor and first mover in fault-managed power, a new class of electricity transmission, and positions Digital Electricity against conventional AC and high-voltage DC installations within the power distribution market, which its Series B announcement characterizes as multi-hundred-billion-dollar in size.
Positioning rests on safety (packetized power checked before delivery, current cut off within milliseconds), installation speed and lower disruption (use of existing data pathways and hybrid fiber cable, reduced permitting in some regions), and cost (smaller electrical room footprint, lower commodity cost, more wire per raceway), plus patent protection and code recognition of fault-managed power.
Technology
Digital Electricity is a patented fault-managed power format in which electricity is sent in discrete, individually verified packets embedded with data. Faults are detected and hazardous current stopped within milliseconds, permitting distribution at hundreds of volts and thousands of watts. Power can be carried over off-the-shelf data cable or hybrid fiber cable in existing data pathways. Product generations include Generation 2 (2017) and Gen2E (2021). Fault-managed power was adopted into the 2023 National Electrical Code, with Class 4 introduced in the 2023 edition of NFPA 70.
Go-to-market
The company sells through and with industry partners in power and connectivity, publishes white papers, product brochures, application guides, education series content and a podcast, and works with other manufacturers to embed the technology in third-party devices. A partnership with Eaton targets critical infrastructure. Series B proceeds were earmarked in part for industry education and partnership development.
Building owners and operators, service providers and network operators, data center operators, transportation hubs, industrial and manufacturing sites, and indoor agriculture growers. Installations span stadiums, airports, convention centers, office towers, hotels, condominiums, hospitals, medical buildings and indoor gardens.
Geography
Headquartered in East Greenwich, Rhode Island, United States, with deployments the company describes as around the world.
History
VoltServer was incorporated in 2011 and formally opened its doors in East Greenwich, Rhode Island in July 2013. Slater Technology Fund invested $250,000 in 2012, followed by a $2M Series A in 2013, a $1M Department of Energy grant and a $5M Series A2 in 2015, and $7.4 million in 2019. The company participated in a US Department of Energy "Plug-and-Play" solar research project in 2014 and began shipping Digital Electricity solutions in 2015 (an earlier company page cites early 2014 shipping in one account and 2015 in another). Milestones include powering Willis Tower in Chicago (2016), a second-generation Digital Electricity platform (2017), deployments at Amtrak headquarters GPON optical LAN (2017), the Sinclair Autograph Hotel (2018), a Miami stadium (2020) and Facebook's SuperCell (2020), Gen2E shipments starting in 2021, and the introduction of the Class 4 term in the 2023 edition of NFPA 70. A $17.5M Series B closed in April 2023.
