Capital Switchgear Limited is scaling to support the next generation of mission critical power infrastructure.

Over the last 12 months, we have continued to invest in our people, systems, facilities, and manufacturing capacity to support data centre, hyperscale, biopharma, and critical infrastructure clients.

Capital is founder-led by Stephen Cullen and Michael Sinkey. That gives our clients direct access to fast decision making, clear accountability, and an agile business that can respond quickly when project requirements change.

For data centre operators and hyperscale clients, that matters.
When power infrastructure is on the critical path, slow decisions create risk.

Capital’s founder-led structure helps us move quickly, align priorities, and keep delivery progressing.
Recent investments and expansions include:
⚡ Dublin-based production facility and HQ
⚡ 100,000 sq. ft. production capacity by end 2026
⚡ Team growth of 150 employees by 2027
⚡ 60,000+ cubicles of switchgear installed globally
⚡ 300MW of data centre power installed
⚡ LV switchgear delivered across six out of seven continents

Capital combines the agility of a founder-led specialist with the manufacturing capacity, quality systems, and technical discipline required to deliver LV switchgear at scale.

Built for speed. Engineered for reliability. Focused on mission critical delivery.

Here's to everything achieved so far, and to what's ahead.

As the demand for high-performance computing continues to grow, infrastructure must evolve to be faster to deploy, globally compliant, and built for resilience at the edge.

This project highlights our delivery of back-to-back MDCs, UL-certified and IEC-compliant, designed to support scalable, decentralised data centre deployments wherever they are needed.

A step forward in enabling the next generation of edge infrastructure.

Capital significantly expands ATS manufacturing capacity

We have made a strategic investment to scale our Automatic Transfer Switch (ATS) production in support of program-based, high-volume data centre deployments.

Our move to a new 50,000 sq ft manufacturing facility, with expansion to 100,000 sq ft planned for 2026, enables parallel ATS production lines, increased throughput, and predictable delivery times, without compromising quality.

By designing our production floor around modular ATS architectures and lean, standardised manufacturing, we support large batch orders, phased rollouts, and consistent builds across multiple sites.

With ISO 9001, 14001 & 45001-certified processes and an EcoVadis Bronze rating awarded for the second consecutive year, our manufacturing supports responsible, lower-impact production with the delivery of reliable, repeatable ATS solutions at scale for mission-critical environments.
