AB Power Systems

What AB Power Systems does

AB Power Systems Ltd, founded in 1990 in Dublin by Brian Holohan and Aileen Dunne, designs, manufactures, distributes, installs, and services battery-based standby power systems for Irish enterprise and infrastructure customers. Its core offerings comprise DC power systems, battery chargers, batteries, and control panels for mission-critical applications in telecommunications, power generation (notably ESB), renewable energy (wind, solar, and battery storage plants), UPS, emergency lighting, switch tripping, and engine starting. The company designs and manufactures more than 90% of the products it sells in-house at its Dublin 12 facility, while distributing standby batteries from multinational OEMs including Enersys, AEES, Alcad/Saft, Haze, Yuasa, Eltek Delta, and CP Power & Automation.

The business operates on a direct sales and field-sales model with quote-based pricing, bundling design, manufacturing, installation, commissioning, and long-term after-sales maintenance into tailored support packages that function as ongoing partnerships rather than transactional sales. Revenue streams are hardware sales, professional installation/commissioning services, and managed maintenance/support services. The company maintains ISO 9001 certification continuously since 1999 and achieved ISO 14001 in 2025, is a member of ISME, and is privately held, founder-owned, and bootstrapped with no disclosed external funding. Geographic scope is primarily Ireland with limited export activity tied to Irish customers' overseas operations.

With 11–50 employees and 36 years of continuous operation, the company is a small specialist manufacturer whose competitive position rests on deep domain expertise, long-tenured customer relationships, and its role as a local one-stop-shop for multinational and overseas firms operating in the Irish market. Its most significant strategic shift has been the mid-2000s pivot from telecommunications into power generation and renewables, aligning the business with Ireland's grid decarbonization and battery storage capex cycle.

Broad incumbents

• ABB: Global leader in electrification, motion, and process automation with a broad portfolio spanning switchgear, transformers, power distribution, and renewable energy integration. Overlaps with AB Power Systems on power plant auxiliary power and renewable applications at utility scale.
• Eaton: Diversified power management company producing switchgear, UPS, power distribution panels, and battery-backed DC power systems. Overlaps with AB Power Systems' product set across switchboards, panels, and UPS, with a much larger industrial and utility customer base.
• Schneider Electric: Global specialist in energy management and automation with deep exposure to switchgear, UPS, DC power systems, and renewable integration. Comparable across product (switchboards, panels, UPS) and end-markets (utilities, renewables, data centers, telecom).
• Vertiv: Global provider of critical digital infrastructure including DC power systems, UPS, switchgear, and monitoring for data centers, telecom, and energy. Comparable as a broader incumbent offering the same end-to-end DC power stack AB Power Systems assembles, but at enterprise scale across many geographies.

Direct peers

• Eltek (Delta Electronics): Manufacturer of high-efficiency rectifiers, battery chargers, and DC power systems for telecom and industrial applications, now part of Delta Electronics. Direct comparable as a power electronics OEM whose products AB Power Systems distributes and which competes for the same DC power system specifications.
• EnerSys: Global manufacturer of industrial batteries including standby power batteries for telecom, utility, and renewable applications. Direct comparable as the lead battery supplier AB Power Systems distributes; an overlap that makes EnerSys both a partner and a competitor should it decide to sell direct into Ireland.
• GS Yuasa: Japanese battery manufacturer with a strong European presence in industrial standby and motive batteries. Comparable as an OEM whose products AB Power Systems distributes, competing for the same standby and renewable backup power specifications.
• Saft (TotalEnergies): Industrial battery specialist (now part of TotalEnergies) producing cells and systems for backup, renewable integration, and grid storage. Direct overlap with AB Power Systems on standby power batteries and battery storage plant auxiliary DC power distribution.
• Socomec: European specialist in power conversion, switching, and UPS with a strong presence in critical power applications including data centers, healthcare, and renewable energy. Comparable as a focused critical-power manufacturer with overlapping switchgear, UPS, and DC power system offerings.
• Hoppecke: European manufacturer of industrial batteries and energy storage systems serving rail, motive, automotive, and stationary standby power markets. Direct comparable as a specialist industrial battery producer targeting telecom, utility, and renewable backup applications similar to AB Power Systems' served markets.
