National Grid

National Grid plc is a British multinational electricity and gas utility headquartered in London. The company operates regulated networks and related infrastructure in the United Kingdom and the Northeastern United States, with activities spanning electricity transmission and distribution, gas transmission and distribution, and associated property and infrastructure services. In its 2025 financial year National Grid reported revenue of about £18.4 billion and employed around 31,645 people, reflecting its position as one of the world’s largest investor‑owned utilities. In Great Britain, National Grid Electricity Transmission owns and maintains the 275 kV and 400 kV high‑voltage electricity transmission network in England and Wales and part‑owns major cross‑border interconnectors such as the HVDC Cross‑Channel link to France and the BritNed interconnector to the Netherlands. Through its acquisition and rebranding of Western Power Distribution, it also operates as National Grid Electricity Distribution, the regional distribution network operator for the East and West Midlands, South West England and South Wales, supplying nearly eight million customers. The group is investing heavily in large onshore reinforcements under “The Great Grid Upgrade” and in subsea projects such as the Eastern Green Links to move power from Scottish offshore wind to English demand centres. National Grid Ventures develops and operates electricity interconnectors and is progressing offshore hybrid assets like the LionLink and Nautilus concepts to combine interconnection with offshore wind collection hubs. In the United States, National Grid’s New England and New York segments own and operate electricity and gas transmission and distribution networks serving customers in Massachusetts and New York, and historically Rhode Island. The company is investing billions of dollars annually in network modernisation and “cleaner, greener” technologies, including offshore wind connections, battery storage on Nantucket and acquisitions of solar and wind generation. Across its businesses, National Grid positions its strategy around enabling decarbonisation and security of supply, including support for a zero‑carbon electricity system in Great Britain and the large‑scale integration of offshore wind through coordinated network designs and interconnector capacity.
