The origins of National Grid Transco date back to the early 1990s, when the U.K. government privatized the electricity sector and established the National Grid Company to manage high-voltage transmission lines. In 2002, the business merged with Lattice Group, the former gas transporter, creating National Grid Transco. Over the years, the company has expanded its U.S. footprint through strategic acquisitions and investments in modernizing aging networks and enhancing cross-border energy interconnections.

National Grid Transco’s core services include the operation, maintenance and development of high-voltage electricity networks and extensive gas pipeline systems. In the U.K., it is responsible for ensuring the secure flow of power from generators to distribution networks and for managing the national gas transmission system. In the U.S., its regional utilities provide end-to-end delivery, metering services and emergency response capabilities. The company is actively involved in connecting renewable energy projects, advancing smart grid technologies and investing in infrastructure upgrades to support decarbonization goals.

Headquartered in London, with a significant regional presence based in Waltham, Massachusetts, National Grid Transco is led by Group Chief Executive John Pettigrew and overseen by a board of directors chaired by John Allan. The company emphasizes safety, reliability and environmental stewardship, aligning its long-term strategy with evolving regulatory requirements and stakeholder expectations in both the U.K. and U.S. energy markets.
