H&MV Engineering

What H&MV Engineering does

H&MV Engineering is a specialist provider of high-voltage electrical engineering and construction services, operating across design, build, testing, and maintenance of transmission and distribution infrastructure at voltage levels from 138 kV to 345 kV. The company is organized around three core verticals — Data Centres, Renewable Energy (wind, solar, battery energy storage), and Utilities (substation construction, T&D systems) — and serves enterprise clients including Copenhagen Infrastructure Partners and ESB on flagship projects such as the Maynooth 220/110 kV GIS substation and the 500 MW Coalburn battery facility in Scotland, the largest battery farm in Europe.

The firm operates from a primary headquarters in Limerick, Ireland, with an 18-office international footprint spanning Ireland, the United Kingdom, Norway, Sweden, Denmark, the Netherlands, Germany, Italy, Spain, Portugal, Croatia, India, and a U.S. regional headquarters in Dallas, Texas. Operations are anchored by technical certifications including ISO 9001, ISO 14001, ISO 45001, ISO 50001, and LRQA NERS accreditation, combined with a proprietary H&MV Academy offering City & Guilds Assured high-voltage switching, refresher, and substation access courses delivered in a real substation training environment in Cashel, Ireland.

H&MV pursues a project-based, quote-driven professional services revenue model, selling directly to enterprise clients through a field sales motion. The company is privately held, with private equity firm Exponent as primary backer and LGT Capital Partners joining as a minority investor in September 2024 at a €750 million post-money valuation. Annualized revenues exceed $1 billion, having quadrupled since 2022, with recent inorganic moves including the acquisition of U.S. substation contractor Cooke Power Services (January 2026) and an investment in grid consultancy Blake Clough Consulting (December 2025) extending the service stack upstream into grid connection advisory.

Direct peers

• MasTec: MasTec's Power Delivery segment constructs HV transmission lines, substations, and distribution infrastructure across the U.S. Closely comparable specialty contractor model for utility and renewable developers, particularly relevant to H&MV's U.S. growth ambitions.
• Burns & McDonnell: Burns & McDonnell is a U.S. employee-owned engineering, architecture, and construction firm with a strong T&D practice delivering substation, transmission, and renewable interconnection work. Comparable services, customers, and delivery model to H&MV, especially in U.S. utility markets.
• MYR Group: MYR Group's T&D segment delivers HV substations, transmission lines, and distribution infrastructure across North America. Closely comparable specialist electrical construction services for utility and renewable clients, though with a heavier U.S. concentration than H&MV.
• Morrison Energy Services: Morrison Energy Services is a UK-based HV electrical infrastructure contractor serving utilities, renewables, and rail. Comparable to H&MV in HV substation and grid-connection delivery across the UK and Ireland markets.
• Kirby Group Engineering: Kirby Group is an Irish-headquartered mechanical and electrical engineering contractor delivering HV, process, and data-centre projects across Europe. Most direct Irish peer to H&MV in terms of geography, customer mix, and HV substation capability.
• Quanta Services: Quanta Services is the largest pure-play electric power infrastructure services firm in North America, delivering HV transmission, substation, and renewable interconnection EPC. Directly comparable business model and customer base to H&MV, especially for the U.S. data-centre and utility segments H&MV is targeting via Cooke Power Services.

Broad incumbents

• ABB: ABB's Electrification business provides switchgear, substation automation, and grid solutions globally. While primarily an OEM, it competes with H&MV's substation EPC and services through system integrator and partner channels.
• Hitachi Energy: Hitachi Energy is a global leader in HV transmission and substation technologies, offering transformers, switchgear, and grid solutions. It competes with H&MV's HV substation EPC scope but at much larger scale and with OEM equipment ownership.
• Siemens Energy: Siemens Energy provides HV grid technology, substation solutions, and EPC services across transmission, renewables, and data-centre infrastructure globally. Overlaps H&MV's HV substation and grid-connection delivery but operates as a broad energy OEM and EPC incumbent.
• EMCOR Group: EMCOR Group delivers electrical and mechanical construction, including HV substation and data-centre infrastructure, across the U.S. and internationally. Overlaps H&MV's data-centre HV delivery but is a much broader building and industrial services platform.
