Grid Hardware Stocks: 58 Listed Global Companies

GE Vernova

GE Vernova was spun off from General Electric in April 2024 and operates across three segments: Power (gas turbines, nuclear, hydro), Wind (onshore and offshore), and Electrification. The Electrification segment is the direct grid hardware play, covering HVDC systems, power transformers, switchgear, substations, synchronous condensers, and grid automation software under the GridOS platform. Electrification equipment backlog quadrupled to $35 billion in four years and is projected to double again by 2028, driven by offshore wind connections, data centre load growth, and utility grid modernisation across North America, Europe, and the Middle East. The February 2026 acquisition of Prolec GE — a transformer joint venture previously 50%-owned — added approximately $3 billion in annual revenue and seven manufacturing sites, five of them in the United States, reinforcing GEV's position as a leading North American transformer supplier. The company's installed base generates roughly 25% of global electricity output, giving its grid equipment business deep utility relationships across more than 100 countries.

ABB

ABB is a Swiss electrification and automation company with around 110,000 employees operating in approximately 100 countries, formed through the 1988 merger of Asea AB and BBC Brown Boveri. It operates three continuing business areas — Electrification, Motion, and Automation — with Electrification (52% of 2025 revenues) as the most grid-relevant, covering distribution switchgear, MV/LV protection, smart power, transformers, grid-edge devices, and service. Full-year 2025 revenues reached $33.2 billion, with Electrification generating $4.1 billion in Operational EBITA at a segment margin of approximately 24%. Q1 2026 orders hit a record $6.6 billion, up 51% year-on-year, with order backlog reaching $11.5 billion. ABB also holds a position in power electronics relevant to grid through its Motion segment, which acquired Gamesa Electric's power conversion business from Siemens Energy in late 2025. Shares trade primarily on the SIX Swiss Exchange (ABBN) and Nasdaq OMX Stockholm (ABB), with OTC American Depositary Shares under ABBNY.

Schneider Electric

Schneider Electric is a French energy management and industrial automation company with approximately 150,000 employees, serving four end markets: data centres and networks, buildings, industry, and infrastructure. Its grid-relevant offer centres on medium- and low-voltage switchgear, power distribution equipment, prefabricated substations, and grid protection systems sold under brands including Merlin Gerin, Square D, and Clipsal. The company also supplies grid automation and SCADA software through its ETAP and EcoStruxure platforms. Full-year 2025 revenues were approximately EUR 38 billion, with an Energy Management backlog of EUR 21.3 billion at year-end reflecting strong data centre and grid modernisation demand. Data centres represent more than one-third of group orders and are the single fastest-growing end market, with Schneider covering the full electrical stack from MV switchgear to rack-level power distribution. The company has no fossil fuel generation exposure, making it a pure-play electrification and automation business.

Siemens Energy

Siemens Energy was spun off from Siemens AG in September 2020 and operates four segments: Gas Services, Grid Technologies, Transformation of Industry, and Siemens Gamesa (wind). Grid Technologies is the direct grid hardware business, generating EUR 10.5 billion in FY2025 revenue at a reported margin in the mid-teens, with an order backlog of EUR 42 billion — roughly double FY2023 levels. The segment covers HVDC converter stations and offshore grid connections, AIS and GIS substations, power and distribution transformers, switchgear, and grid stabilisation equipment including STATCOM, shunt reactors, and phase shifters. Siemens Energy holds a number-one global market position in HVDC solutions and substations, and a number-one position in power transformers by volume. Transformer capacity is being expanded with approximately EUR 2 billion of factory investment targeted through FY2028, including new facilities in Austria and Croatia and a new Canadian plant at Trois-Rivieres. The EUR 42 billion Grid Technologies backlog provides multi-year revenue visibility, with HVDC and offshore grid connection contracts running five to seven years.

Eaton

Eaton is an Irish-domiciled power management company incorporated in Dublin and listed on the NYSE, with approximately 100,000 employees and operations in more than 175 countries. Its Electrical Americas and Electrical Global segments — collectively the dominant share of revenues — supply switchgear, circuit breakers, transformers, busway, UPS systems, power quality equipment, and data centre power infrastructure. The company is executing a strategic separation of its Vehicle and eMobility businesses, expected to complete by end of Q1 2027, which will leave a streamlined electrical and aerospace business. Electrical Americas segment margin is targeted at 32% by 2030. Eaton is a direct beneficiary of US grid modernisation, IRA-driven manufacturing investment, and hyperscaler data centre build-out; management has characterised the current environment as a multi-year demand upcycle for electrical infrastructure. In early 2026, Eaton acquired Resilient Power Systems, a developer of solid-state transformer technology, extending its position into next-generation grid hardware.
